    1. "ISRO conceiving two national parks is a signal for increased privatization of the

    nation’s space program” comment.

    Ans. Two space industry enclaves or “parks” that have been conceived one for

    launchers at Sriharikota and a smaller one at an existing Bangalore spacecraft campus

    signal increased privatization of the nation’s space program over the nex t five years.

    For now, the facilities will be “captive” to drive the future missions of the Indian Space

    Research Organization.

    First, ISRO wants to groom and engage domestic industry in the launch vehicles area

    from integrating sub-systems up to assembling, and even launching the PSLV.

    Eventually the future consortium will be fully responsible for building and launching the

    light-lift PSLV rocket.

    As part of Make in India initiative, Indian Space Research Organization (ISRO) has

    decided to open a 100 acre Space Park in Bangalore where private industries would be

    allowed to take up manufacturing of space system related components.

    The Space Park spread in 100 acres of Whitefield area is expected to cater to increasing

    demand for components and other parts for satellites as India aims to launch more

    satellites for various observational services in future. India plans to launch 12 satellites

    in 2016 for remote sensing and navigation

    M.Annadurai (ISRO satellite centre director) said that the Space Park will also

    contribute to the government’s ‘Make in India’ initiative as the private industry and HAL

    (Hindustan Aeronautics Ltd) have been helping us in making rockets and satellites over

    the years.

    M.Annadurai also talked about progress so far in the second lunar mission Chandrayaan

    2 and solar mission Aditya.

    “India will be the first country to have a high altitude polar landing of Chandrayaan 2

    and it will have three components – orbiter, Lander and rover – to study the lunar

    surface. The mission is scheduled to be launched 2017- 18”.

    Chandrayaan 2 has a capability to soft land at a specified lunar site and carries in-situ

    chemical analysis of the lunar surface and will have Orbiter Craft and Lander craft.

    2. What is 'crab pulsar'? Give a brief account of it.

    Ans . A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron

    star that emits a beam of electromagnetic radiation. This radiation can be observed only

    when the beam of emission is pointing toward Earth, much the way a lighthouse can be

    seen only when the light is pointed in the direction of an observer, and is responsible for

    the pulsed appearance of emission. Neutron stars are very dense, and have short,

    regular rotational periods. This produces a very precise interval between pulses that

    range roughly from milliseconds to seconds for an individual pulsar. Pulsars are believed

    to be one of the candidates of high and ultra-high energy astroparticles (see also

    centrifugal mechanism of acceleration).

    The precise periods of pulsars make them useful tools. Observations of a pulsar in a

    binary neutron star system were used to indirectly confirm the existence of gravitational

    radiation. The first extra solar planets were discovered around a pulsar, PSR B1257+12.

    Certain types of pulsars rival atomic clocks in their accuracy in keeping time.

    The Crab Pulsar

    The Crab Pulsar (PSR B0531+21) is a relatively young neutron star. The star is the

    central star in the Crab Nebula, a remnant of the supernova SN 1054, which was

    widely observed on Earth in the year 1054. Discovered in 1968, the pulsar was

    the first to be connected with a supernova remnant.

    The Crab Pulsar is one of very few pulsars to be identified optically. The optical

    pulsar is roughly 20 km in diameter and the pulsar "beams" rotate once every 33

    milliseconds, or 30 times each second. The out flowing relativistic wind from the

    neutron star generates synchrotron emission, which produces the bulk of the

    emission from the nebula, seen from radio waves through to gamma rays.

    The most dynamic feature in the inner part of the nebula is the point where the

    pulsar's equatorial wind slams into the surrounding nebula, forming a

    termination shock. The shape and position of this feature shifts rapidly, with the

    equatorial wind appearing as a series of wisp-like features that steepen, brighten,

    and then fade as they move away from the pulsar into the main body of the

    nebula.

    The period of the pulsar's rotation is slowing by 38 nanoseconds per day due to

    the large amounts of energy carried away in the pulsar wind.

    Scientist’s latest research: -

    Scientists have discovered the most energetic light ever detected in the universe

    from the centre of a supernova known as ‘Crab pulsar’ which is situated 6,500

    light years away from Earth.

    “We performed dee p observation of the Crab pulsar with MAGIC to understand

    this phenomenon, expecting to measure the maximum energy of the pulsating

    photons,” said Emma de Ona Wilhelmi from the Institute of Space Sciences (IEEC -

    CSIC) in Barcelona.

    The new observations extend this tail to much higher, above trillion electron volt

    (TeV) energies, which is several times more energetic than the previous

    measurement,” added Roberta Zanin from ICCUB -IEEC, Barcelona.

    It is surrounded by a region of intense magnetic field 10 thousand billion times

    stronger than that of the Sun.

    The new discovery challenges current theories about how neutron stars operate,

    3. Write a short note on Nag missile.

    Ans. Nag is a third generation "fire-and-forget" anti-tank missile developed in India. It is

    one of five missile systems developed by the Defense Research and Development

    Organization (DRDO) under the Integrated Guided Missile Development Program

    (IGMDP). Nag has been developed at a cost of 3 billion (US$44.2 million).

    As originally conceived, the Nag would have been available with three different types of

    guidance, a wire guided version, an infra-red version and a mill metric wave (mmw)

    active radar homing version . DRDO failed to develop a wire guidance system leading to

    plans for this being dropped. Currently, guidance is based on an imaging infrared (IIR)

    passive seeker that ensures high-hit accuracy in both top- and front-attack modes.

    The mmW seeker, on the other hand, is intended to operate as an optional system that

    can replace the IIR passive seeker as a module. Also incorporated into the guidance

    system, is a CCD camera. The advantage of this optical seeker is that it is less prone to

    jamming. The missile has a weight of 42 kg and can engage targets at ranges 4 –5 km.

    The Nag is claimed to be first anti-tank missile which has a complete fiberglass

    structure.

    The Nag has a flight speed of 230 meters per second, is armed with an 8 kg tandem

    shaped-charge warhead, has a rocket motor using nitramine-based smokeless extruded

    double base sustainer propellant, has a single-shot hit probability of 0.77 and a CEP of

    0.9 meters, and has a 10-year maintenance-free shelf-life. it was tested from Shamirpet

    in Hyderabad on 13 June 2010.

    The missile tested during the summer in Rajasthan failed to achieve its objective of

    hitting the target at the intended 4 km range. The scientists found the fault with the

    heat seeker unable to distinguish the heat signature of the target and the surrounding

    during extreme temperate at great distance. This led to the development of a better

    seeker with higher resolution and sensitivity by Research Centre Imarat (RCI) that can

    track and distinguish targets at long distances .The first seeker trials were carried out on

    29 July 2013 in the hot desert conditions in Rajasthan. The evaluation trials carried out

    in September/August 2013 with the improved seeker provided fairly accurate results.

    The actual trials are expected to begin in early 2014. In Jan 2016 successfully hit the

    target 4 km away during a night trial in the Mahajan Field Firing Range.

    Indian army: 450 Nag missiles along with 13 NaMiCA (Nag Missile carriers) carriers

    were to be inducted into the Army's arsenal by 2011 with the successful completion of

    final validation trials in Rajasthan; however, this may now take some more time after

    the missile's failure in the user validation trials. The Army also projected in their

    perspective plan the need for 7000 Nag missiles and around 200 NAMICAs.

    4. Write a short note on WIPO and critically analyses the IPR policy of India.

    Ans. WIPO was established in 1967 by the WIPO Convention, which states that WIPO’s

    objective was “to promote the protection of intellectual prope rty throughout the

    world” (WIPO, 1967, Article 3) Headquartered in Geneva, Switzerland.

    WIPO currently administers 24 treaties and facilitates the negotiation of several

    proposed treaties covering copyrights, patents and trademarks.

    The World Intellectual Property Organization (WIPO) is the United Nations specialized

    agency that coordinates international treaties regarding intellectual property rights. Its

    184 member states comprise over 90% of the countries of the world, who participate in

    WIPO to negotiate treaties and set policy on intellectual property matters such as

    patents, copyrights and trademarks.

    WIPO should become “IPR agnostic” and not insist on blindly promoting intellectual

    property rights out of a simple belief that “more is better.” WIPO sho uld explore new

    models of rewarding creativity and promote whatever models encourage the creation

    and dissemination of knowledge and culture. Traditional business models that rely upon

    copyrights and patents are not the only means of promoting creativity and rewarding

    innovation. New viral distribution marketing channels take advantage of the benefits of

    digital technology and work by spreading information, as opposed to preventing access

    to information. WIPO should not favors traditional business models over innovative new

    models in its work programme, and it should refocus its efforts on promoting creativity

    and innovation by whatever means possible.

    Critically analyses the IPR policy of India:-

    Intellectual Property Rights (IPR) refers to rights provided to individuals or organizations

    pertaining to specific innovation or Invention in products or processes for a certain

    period of time. They exist in the form of patents, trademarks, Geographical Indicators

    (GIs), copyrights, etc. IPR intends to spur and incentivize creativity and innovation and

    facilitate access to knowledge in order to achieve social and economic welfare. In 1994,

    member countries of the World Trade Organization (WTO) signed the Trade-Related

    Aspects of Intellectual

    Property Rights (TRIPS), which established the global standards for IPRs. India has the

    Patent’s Act, 1970 under which the patent system operates in the country and the

    Indian Copyright Act, 1957. As a signatory to the TRIPS agreement, India introduced the

    Patent Amendment Act of 2005, which signaled a shift from process patents to product

    patents; to make the act TRIPS compliant. India has based its patent law on the twin

    principles of encouraging protection of IPR and safeguarding public interest through a

    “pro -public health” and “pro -access” stance. However, in light of the recent patent

    judgments passed in notable cases such as the one surrounding Compulsory Licensing

    (CL) in Bayer vs. NATCO, or the decision to not grant patent protection to Glivec (a

    cancer drug manufactured by Novartis since it failed to meet the stipulated novelty

    requirements), there is an increased debate over the country’s IPR policy and laws.

    India on the Global Innovation and IPR Scale :-

    India is ranked 29th out of 30 countries in the International IP Index 2015,

    released by the Global Intellectual Property Center of the US Chamber of

    Commerce. This ranking measures the overall IP environment in a country.

    China is ranked 19th in the same list.

    India ranks 76th out of 143 countries (down from 66 in 2013) on the Global

    Innovation Index 2014 published by Cornell University, INSEAD and World

    Intellectual Property Organization (WIPO). It is the lowest ranked among the

    BRICS nation, with China occupying the 29th rank.

    The policy draft seeks to draw a correlation between a strong IP protection framework

    and increased foreign investment in manufacturing in the country under the ‘Make in

    India’ program; however it does not present any empirical evidence supporting the

    same or raise a point over whether IP protection in itself guarantees more foreign

    investment. On the contrary, it is extremely hard to provide any empirical evidence. In

    the US, while the number of patents has increased from 59,715 patents in 1983 to

    244,341 in 2010, annual growth in the total factor productivity reduced from 1.2% in

    1970- 79 to below 1% in 2000-09 and the annual expenditure on R&D has oscillated in a

    band of 2.5% of the GDP for over three decades

    5. Trace out the breakout of Ebola epidemics and how we are trying to fight it.

    Ans . An observational study done roughly 29 months after the outbreak on survivors ofthe 2007 Bundibugyo Ebola virus outbreak in Uganda found that long-term sequelae

    (consequences) persisted for more than two years after Ebola virus disease. Symptoms

    included eye pain, blurred vision, hearing loss, difficulty swallowing, difficulty sleeping,

    arthralgias, memory loss or confusion, and "various constitutional symptoms controlling

    for age and sex".

    From August through December 2014, a total of 10 patients with Ebola were treated in

    U.S. hospitals; of these patients, 8 survived. In March 2015, the U.S. CDC interviewed

    the survivors; they all reported having had at least one adverse symptom during their

    recovery period. The symptoms ranged from mild (for instance hair loss) to more severe

    complications requiring rehospitalization or treatment. The most frequently reported

    symptoms were lethargy or fatigue, joint pain, and hair loss. Sixty-three percent

    reported having eye problems including two who were diagnosed with verities, 75%

    reported psychological or cognitive symptoms, and 38% reported neural difficulties.

    Although most symptoms resolved or improved over time, only one survivor reported

    complete resolution of all symptoms.

    A study published in May 2015 discussed the case of Ian Crozier, a Zimbabwe-born

    physician and American citizen who became infected with Ebola while he was working

    at an Ebola treatment center in Sierra Leone. He was transported to the US and was

    successfully treated at Emory University Hospital. However, after discharge Crozier

    began to experience symptoms including low back pain, bilateral enthesitis of the

    Achilles tendon, paresthesias involving his lower legs, and eye pain, which was

    diagnosed as uveitis. His eye condition worsened and a specimen of aqueous humor

    was obtained from his eye which tested positive for Ebola. The authors of the study

    concluded "Further studies to investigate the mechanisms responsible for the ocular

    persistence of Ebola and the possible presence of the virus in other immune-privileged

    sites (e.g., in the central nervous system, gonads, and articular cartilage) are

    warranted." The authors also noted that 40% of participants in a survey of 85 Ebola

    survivors in Sierra Leone reported having "eye problems", though the incidence of

    actual uveitis was unknown.

    Another study which was released in August 2015 looked at the health difficulties that

    have been reported by survivors. Calling the set of symptoms "post-Ebola virus disease

    syndrome (PEVDS)", the research found symptoms which included "chronic joint and

    muscle pain, fatigue, anorexia, hearing loss, blurred vision, headache, sleep

    disturbances, low mood and short-term memory problems." The research suggests that

    "implementation of specialized health services to treat and follow-up survivors" is

    needed.

    In early December, the WHO reported that at a national level there were a sufficient

    number of beds in treatment facilities to treat and isolate all reported Ebola cases,

    although the uneven distribution of cases was resulting in serious shortfalls in some

    areas. Similarly, all affected countries had sufficient and widespread capacity to bury all

    reported deaths; however, because not all deaths are reported, it was possible that

    some areas still had insufficient burial capacity. They reported that every district now

    had access to a laboratory to confirm cases of Ebola within 24 hours from sample

    collection, and that all three countries had reported that more than 80% of registered

    contacts associated with known cases of EVD were being traced, although contact

    tracing was still a challenge in areas of intense transmission and in areas of community

    resistance.

    A number of Ebola Treatment Centers were set up in the area, supported by

    international aid organizations and staffed by a combination of local and international

    staff. Each treatment centre is divided into a number of distinct and rigorously separate

    areas. For patients, there is a triage area, and low- and high-risk care wards. For staff,

    there are areas for preparation and decontamination. An important part of each centre

    is an arrangement for safe burial or cremation of bodies, required to prevent further

    infection. In January 2015, a new treatment and research center was built by Rusal and

    Russia in the city of Kindia in Guinea. It is one of the most modern medical centers in

    Guinea. Also in January, MSF admitted its first patients to a new treatment centre in

    Kissy, an Ebola hotspot on the outskirts of Freetown, Sierra Leone. The center has a

    maternity unit for pregnant women with the virus.

    6. What are recent developments in India to overcome the concern of rising

    antimicrobial resistance, a serious health issue in India? Discuss

    Ans. Antibiotic resistance in microorganisms, especially in bacterial species, has

    become an eminent and serious concern in the field of healthcare and medicine.

    Decrease in new antibiotic research permitted a rise in bacterial drug resistance.

    Antibiotic resistant bacteria have been found in the initial stages of antibiotic use, but

    over the time, they have become resistant to more than one antibiotic, termed as

    multidrug resistant organisms (also called “superbugs”). Bacteria now are frequently

    resistant to many if not all of the antibiotics. Inappropriate use and misuse of antibiotics

    are significant factors for the increase in antibiotic resistant bacteria and thus evoked

    counter attack. Hence, we are now experiencing a rapid increase in the number of

    alternative approaches to combat these antibiotic resistant bacteria.

    Antibiotic Resistance and its Current Aspects : Antibiotic resistance has become a major

    concern in the present-day world. Most of the antibiotic resistant bacteria may have

    attained resistance to the first-line antibiotics. This has necessitated the development of

    second-line antibiotics. With a slowdown in the development of antibiotics in the past

    decade, the resistance level of bacteria has increased many folds, which demand the

    development of new drugs. Currently, newer classes of compounds, including

    antimicrobial peptides, bacterial biosynthetic inhibitors, etc., have given an upper hand

    against antibiotic resistance. The recently developed carbapenem family of betalactum

    antibiotics exhibit broad-spectrum activity. A number of next-generation

    fluoroquinolones currently are in developmental stages. Moreover, the use of lytic

    bacteriophages to manage bacterial infections is accelerating the current research

    developments. However, just like a bacteria, bacteriophages can also acquire resistance

    to phages that attack them. Thus, phages can evolve resistance and adapt to resistant

    bacteria. Looking at the current situation, there does seem to be a necessity to identify

    and develop compounds that can address the problem of antibiotic resistance. The

    threat of resistant bacteria is a critical public health issue that requires a coordinated

    and multifaceted response.

    New and Alternative Approaches: Prevention is (always) better than cure. Avoiding

    infections will reduce the use of antibiotics, further inhibiting the incidence of resistance

    development in bacteria. A closer look at antibiotic resistant infections and the causes

    and analyzing them will help the scientific community to develop new and specific

    strategies to prevent them. Avoiding inappropriate use and misuse of antibiotics would

    slow down the spread of resistant bacteria. As bacteria always evolve and can develop

    more and more resistance, new antibiotics are needed to fight against them. WHO

    recommends guidelines and some global strategies to fight and overcome this serious

    issue? Latest strategies and approaches to tackle antibiotic resistant bacteria are

    described in the following sections:-

    Photodynamic Therapy (PDT): PDT uses the interaction of light with a

    photosensitize to inactivate bacteria. Photosensitize binds to the target cell and is

    activated by irradiation with a light of suitable wavelength. During this process,

    reactive oxygen species are generated that will produce bactericidal effect by

    damaging multiple cellular structures. It has been found that anaerobic bacteria

    that lead to periodontal diseases can be suppressed using PDT. In a research by

    Minnock et al. it was concluded that chlorine e6 and BLC 1010 is able to suppress

    periodontopathogenic bacteria. The efficiency of PDT can be improved by

    chemical derivatisation or conjugation of photosensitizes; e.g., introduction of

    side chains into the dye molecule ethylene blue and porphirins has shown

    optimized results. Although there are some adverse effects such as impairment of

    benign oral flora that may further develop to a single resistant species, scar

    formation and phototoxic effects, PDT has a great benefit when the resistance

    against antibiotics become worse.

    Antimicrobial Peptides (AMPs): Recent findings suggest that AMPs could be used

    as a therapeutic model for designing new class of antibiotics. AMPs are basically

    small peptides produced as part of non-specific immune response in many

    organisms of both animal and plant kingdom. Study of AMPs as novel therapeutic

    agents is in experimental stages. Hypotheses have been made regarding whether

    these peptides can interfere with DNA as well, but this is yet to be evaluated for

    confirmation. McGrath et al. synthesized a low-toxicity Lys-Leu or kloth (KL)

    peptide called (KLAKLAK)2 toward mammalian cells. A variant of (KLAKLAK) 2 —

    known as D(KLAKLAK) 2—has been studied for antimicrobial activity. The study

    successfully showed the inhibition of several gram-negative bacteria. In another

    experiment, Barbu et al.showed that D(KLAKLAK) 2 induced apoptosis in mucor.

    The molecule was also shown to inhibit germination and reduce hyphal activity,

    yielding a fungicidal effect. With technological advancements, some of the

    limitations like toxicity, stability, drug delivery mechanism, etc., can be resolved,

    and then this new class of antibiotics could be a promising antimicrobial in the

    market.

    7. Discuss the macroeconomic impacts of renewable energy deployment in the

    context of recent IRENA's report on renewable energy.

    Ans. This paper builds on the results of the study “Macroeconomic Effects of the Energy

    Transition” in Germany conducted by Prognos/EWI/GWS for the German Federal

    Ministry for Economic Affairs and Energy. The goal was to analyze the effects of the

    German energy transition on the economy, energy system and emissions. Two scenarios

    have been defined. The Counter-Factual scenario describes the development without

    the energy transition and is based on the assumptions of the reference scenario given in

    the “Energy Scenarios 2010”. The Energy Transition sce nario reflects historical

    developments up to 2013 and the expected development up to 2020 is based on the

    Energy Reference Forecast. The main differences between the two scenarios are the

    expansion of renewable energy in gross electricity production and the improvements in

    energy efficiency. The model PANTA RHEI shows the interrelations between the

    economy, energy system and environment. The economic core of the model consists of

    input-output tables, system of national accounts and the labor market. The economic

    module is extended by an environmental module. That includes i. a. energy balances

    and energy prices. Both modules are linked in a consistent way. The Counter-Factual

    and Energy Transition scenario have been implemented in the model. The results show

    that the investments in renewable energy and energy efficiency have a positive effect

    on GDP and employment. EEG surcharge leads to increased electricity prices for most

    consumer groups except the electricity-intensive industries. As a consequence the price

    index rises. In combination with decreasing investments in the electricity market from

    2013 onwards, employment and GDP effects become lower over time.

    Recent IRENA's report on renewable energy:-

    Renewable energy jobs reached an estimated 7.7 million in 2014, excluding large

    hydropower.

    Jobs in the sector increased 18% from the estimate reported last year and the

    regional shifts towards Asia continued, especially in manufacturing.

    The 10 countries with the largest renewable energy employment were China,

    Brazil, the United States, India, Germany, Indonesia, Japan, France, Bangladesh

    and Colombia.

    In 2014, the solar PV sector accounted for 2.5 million jobs, of which two-thirds

    were in China. Solar PV jobs also grew in Japan, while decreasing in the European

    Union.

    Bio-fuels (1.8 million), biomass (822,000) and biogas (381,000) are also major

    employers, with jobs concentrated in the feedstock supply. While Brazil and the

    United States continued to dominate, Southeast Asia saw growth in bio-fuel jobs,

    reflecting measures to support production.

    Wind employment crossed the 1 million mark, with China accounting for half of

    these jobs. The United States, Brazil and the European Union also saw gains.

    Solar water heating and cooling employed 764,000 people, more than three

    quarters of them in China. Other significant markets are India, Brazil and the

    European Union.

    Small hydropower employed about 209,000 people, more than half in China,

    followed by the European Union, Brazil and India.

    Large hydropower was estimated to support another 1.5 million direct jobs,

    mostly in China and largely in construction and installation.

    An array of industrial and trade a policy continues to shape employment, with

    stable and predictable policies favoring job creation.

    8. Write a short note on vegetation in space.

    Ans . Lettuce, peas and radishes are just a few vegetables that are found in a summer

    garden. But did you know these same vegetables also can be grown in space? Crew

    members aboard the International Space Station have been growing such plants and

    vegetables for years in their "space garden."

    "Growing food to supplement and minimize the food that must be carried to space will

    be increasingly important on long-duration missions," said Shane Topham, an engineer

    with Space Dynamics Laboratory at Utah State University in Logan. "We also are

    learning about the psychological benefits of growing plants in space -- something that

    will become more important as crews travel farther from Earth."

    The experiment has four major objectives: to find out if the produce grown in space can

    be consumed safely; what types of microorganisms might grow on the plants and what

    can be done to reduce the threat of microorganisms in the hardware prior to launch;

    what can be done to clean or sanitize the produce after it has been harvested; and how

    to optimize production compared to the resources required to grow it.

    Since 2002, the Lada greenhouse has been used to perform almost continuous plant

    growth experiments on the station. Fifteen modules containing root media, or root

    modules, have been launched to the station and 20 separate plant growth experiments

    have been performed.

    I don’t see future space crews leaving the Earth for long durations without having the

    ability to grow their own food," said Topham. "The knowledge that we are gaining is

    enabling us to extend our exploration and future colonization of space."

    9. What are the reasons Pluto is not considered as ninth planet? Discuss.

    Ans. Our first discussion of this part what is Pluto: -

    Pluto was discovered in 1930 by an astronomer from the United States. An astronomer

    is a person who studies stars and other objects in space.

    1. Pluto was known as the smallest planet in the solar system and the ninth planet

    from the sun. Today, Pluto is called a “dwarf planet.” A dwarf planet orbits the

    sun just like other planets, but it is smaller.

    2. A dwarf planet is so small it cannot clear other objects out of its path. On average,

    Pluto is more than 3.6 billion miles (5.8 billion kilometers) away from the sun.

    That is about 40 times as far from the sun as Earth. Pluto orbits the sun in an oval

    like a racetrack. Because of its oval orbit, Pluto is sometimes closer to the sun

    than at other times.

    3. At its closest point to the sun Pluto is still billions of miles away. Pluto is in a

    region called the Kuiper (KY-per) Belt. Thousands of small, icy objects like Pluto

    are in the Kuiper Belt. Pluto is only 1,400 miles (2,300 kilometers) wide. That's

    about half the width of the United States. Pluto is slightly smaller than Earth's

    moon. It takes Pluto 248 years to go around the sun. One day on Pluto is about 6

    1/2 days on Earth.

    Following the reason Pluto is not considered as ninth planet Anymore:-

    In 2003, an astronomer saw a new object beyond Pluto. The astronomer

    thought he had found a new planet. The object he saw was larger than Pluto.

    He named the object Eris (EER-is).Finding Eris caused other astronomers to

    talk about what makes a planet a "planet. There is a group of astronomers that

    names objects in space.

    This group decided that Pluto was not really a planet because of its size and

    location in space. So Pluto and objects like it are now called dwarf planets

    .Pluto is also called a plutoid. A plutoid is a dwarf planet that is farther out in

    space than the planet Neptune. The three known plutoids are Pluto, Eris and

    Make . Astronomers use telescopes to discover new objects like plutoids.

    Scientists are learning more about the universe and Earth's place in it. What

    they learn may cause them to think about how objects like planets are

    grouped. Scientist’s group objects that are like each other to better

    understand them. Learning more about faraway objects in the solar system is

    helping astronomers learn more about what it means to be a planet.

    Ans. Our first parts of discussion are what is IRNSS: - IRNSS is an independent regional

    navigation satellite system being developed by India. It is designed to provide accurate

    position information service to users in India as well as the region extending up to

    1500 km from its boundary, which is its primary service area. IRNSS will provide two

    types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS)

    and is expected to provide a position accuracy of better than 20 m in the primary

    service area It is an autonomous regional satellite navigation system being developed by

    Indian Space Research Organization which would be under total control of Indian

    government. The requirement of such a navigation system is driven by the fact that

    access to Global Navigation Satellite Systems like GPS are not guaranteed in hostile

    situations.

    Following details IRNSS project of ISRO :-

    ISRO plans to launch the constellation of satellites between 2012 and 2014.

    ISRO on 1 July 2013, at 23:41 IST launched from Sriharikota the First IndianNavigation Satellite the IRNSS-1A. The IRNSS-1A was launched aboard PSLV-

    C22.

    On 4 April 2014, at 17:14 IST ISRO has launched IRNSS-1B from Sriharikota , its

    second of seven IRNSS series. 19 minutes after launch PSLV-C24 was successfully

    injected into its orbit.

    IRNSS-1C was launched on 16 October 2014, and IRNSS-1D on 28 March 2015. The constellation would comprise 7 satellites of I-1K bus each weighing around

    1450 Kilograms, with three satellites in the Geostationary Earth Orbit (GEO) and 4

    in Geosynchronous Earth Orbit (GSO). The constellation would be completed

    around 2015.

    IRNSS-1D, which will provide navigation, tracking and mapping service and have a

    mission life of 10 years, is the fourth in the constellation of seven satellites,

    planned by Isro to constitute IRNSS, which would be on par with US-based GPS

    once the full complement of spacecrafts are launched IRNSS-1D on 28 March

    2015.

    PSLV-C31 from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota .

    11. What are the factors showing that ninth planet does exist? Discuss.

    Ans . Caltech researchers have found evidence of a giant planet tracing a bizarre, highly

    elongated orbit in the outer solar system. The object, which the researchers have

    nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20

    times farther from the sun on average than does Neptune (which orbits the sun at an

    average distance of 2.8 billion miles). In fact, it would take this new planet between

    10,000 and 20,000 years to make just one full orbit around the sun.

    The researchers, Konstantin Batygin and Mike Brown, discovered the planet's

    existence through mathematical modeling and computer simulations but have

    not yet observed the object directly.

    "This would be a real ninth planet," says Brown, the Richard and Barbara

    Rosenberg Professor of Planetary Astronomy. "There have only been two true

    planets discovered since ancient times, and this would be a third. It's a prettysubstantial chunk of our solar system that's still out there to be found, which is

    pretty exciting."

    Brown notes that the putative ninth planet —at 5,000 times the mass of Pluto —

    is sufficiently large that there should be no debate about whether it is a true

    planet. Unlike the class of smaller objects now known as dwarf planets, Planet

    Nine gravitationally dominates its neighborhood of the solar system. In fact, it

    dominates a region larger than any of the other known planets —a fact that

    Brown says makes it "the most planet-y of the planets in the whole solar system."

    Batygin and Brown describe their work in the current issue of the Astronomical

    Journal and show how Planet Nine helps explain a number of mysterious features

    of the field of icy objects and debris beyond Neptune known as the Kuiper Belt.

    "Although we were initially quite skeptical that this planet could exist, as we

    continued to investigate its orbit and what it would mean for the outer solar

    system, we become increasingly convinced that it is out there," says Batygin, an

    assistant professor of planetary science. "For the first time in over 150 years,

    there is solid evidence that the solar system's planetary census is incomplete."

    The road to the theoretical discovery was not straightforward. In 2014, a former

    postdoc of Brown's, Chad Trujillo, and his colleague Scott Shepherd published a

    paper noting that 13 of the most distant objects in the Kuiper Belt are similar with

    respect to an obscure orbital feature. To explain that similarity, they suggested

    the possible presence of a small planet. Brown thought the planet solution was

    unlikely, but his interest was piqued.

    He took the problem down the hall to Batygin, and the two started what

    became a year-and-a-half-long collaboration to investigate the distant objects. As

    an observer and a theorist, respectively, the researchers approached the work

    from very different perspectives —Brown as someone who looks at the sky and

    tries to anchor everything in the context of what can be seen, and Batygin as

    someone who puts himself within the context of dynamics, considering how

    things might work from a physics standpoint. Those differences allowed the

    researchers to challenge each other's ideas and to consider new possibilities. "I

    would bring in some of these observational aspects; he would come back with

    arguments from theory, and we would push each other. I don't think the

    discovery would have happened without that back and forth," says Brown. " It

    was perhaps the most fun year of working on a problem in the solar system that

    I've ever had."

    12. Write a short note on Zika virus.

    Ans. Zika virus (ZIKV) is a member of the virus family Flaviviridae and

    the genus Flavivirus , transmitted by daytime-active Aedes mosquitoes, such as A.

    aegypti . Its name comes from the Zika Forest of Uganda, where the virus was first

    isolated in 1947.

    The virus was first isolated in April 1947 from a rhesus macaque monkey that had

    been placed in a cage in the Zika Forest of Uganda, near Lake Victoria, by the

    scientists of the Yellow Fever Research Institute. A second isolation from the

    mosquito A. africanus followed at the same site in January 1948. When the monkey

    developed a fever, researchers isolated from its serum a transmissible agent that

    was first described as Zika virus in 1952.

    In humans, the virus causes most often no symptoms or a mild illness known

    as Zika fever, which since the 1950s has been known to occur within a narrowequatorial belt from Africa to Asia.

    In 2014, the virus spread eastward across the Pacific Ocean to French Polynesia,

    then to Easter Island and in 2015 to Mexico, Central America, the Caribbean,

    and South America, where the Zika outbreak has reached pandemic levels.

    Zika virus is related to dengue, yellow fever, Japanese encephalitis, and West

    Nile viruses.

    The illness it causes is similar to a mild form of dengue fever, is treated by

    rest, and cannot yet be prevented by drugs or vaccines.

    There is a possible link between Zika fever and microcephaly in newborn babies

    by mother-to-child transmission, as well as a stronger one with neurologic

    conditions in infected adults, including cases of the Guillain –Barré syndrome.

    In 2015, Zika virus RNAwas detected in the amniotic fluid of two fetuses,

    indicating that it had crossed the placenta and could cause a mother-to-child

    infection. There is a possible link between Zika fever and microcephaly in

    newborn babies by mother-to-child transmission

    In January 2016, the U.S. Centers for Disease Control and Prevention (CDC)

    issued travel guidance on affected countries, including the use of enhanced

    precautions, and guidelines for pregnant women including considering

    postponing travel. Other governments or health agencies soon issued similar

    travel warnings, while Colombia, the Dominican Republic, Ecuador, El

    Salvador, and Jamaica advised women to postpone getting pregnant until

    more is known about the risks. On February 2, 2016, Dallas County Health and

    Human Services confirmed the first case of transmission in the United States.

    Marvin Lee Minsky was born in New York City to an eye surgeon father, Henry, and to a

    Jewish mother, Fannie, who was an activist in Zionist affairs, where he attended The

    Field ston School and the Bronx High School of Science. He later attended Phillips

    Academy in Andover, Massachusetts. He then served in the US Navy from 1944 to 1945.

    He held a BA in mathematics from Harvard (1950) and a PhD in mathematics

    from Princeton (1954). He was on the MIT faculty from 1958 to his death. In 1959 he

    and John McCarthy founded what is now known as the MIT Computer Science and

    Artificial Intelligence Laboratory. At the time of his death, he was the Toshiba Professor

    of Media Arts and Sciences, and professor of electrical engineering and computer

    science.

    Marvin Minsky, “father of artificial intelligence,”

    Marvin Minsky, a mathematician, computer scientist, and pioneer in the field of

    artificia l intelligence, died at Boston’s Brigham and Women’s Hospital on Sunday,

    Jan. 24, of a cerebral hemorrhage. He was 88.

    Minsky, a professor emeritus at the MIT Media Lab, was a pioneering thinker

    and the foremost expert on the theory of artificial intelligence. His 1985 book

    “The Society of Mind” is considered a seminal exploration of intellectual structure

    and function, advancing understanding of the diversity of mechanisms interacting

    in intelligence and thought. Minsky’s last book, “The Emotion Machine:

    Commonsense Thinking, Artificial Intelligence, and the Future of the Human

    Mind,” was published in 2006.

    Minsky viewed the brain as a machine whose functioning can be studied and

    replicated in a computer — which would teach us, in turn, to better understand

    through experience? How, for example, do we teach a sophisticated computer

    that to drag an object on a string, you need to pull, not push — a concept easily

    mastered by a two-year-old child.

    "Very few people produce seminal work in more than one field; Marvin Minksy

    was that caliber of genius," MIT President L. Rafael Reif says. "Subtract his

    contributions from MIT alone and the intellectual landscape would be

    unrecognizable: without CSAIL, without the Media Lab, without the study of

    artificial intelligence and without generations of his extraordinarily creative

    students and protégés. His curiosity was ravenous. His creativity was beyond

    measuring. We can only be grateful that he made his intellectual home at MIT.”

    A native New Yorker, Minsky was born on Aug. 9, 1927, and entered Harvard

    University after returning from service in the U.S. Navy during World War II. After

    graduating from Harvard with honors in 1950, he attended Princeton University,

    receiving his PhD in mathematics in 1954. In 1951, his first year at Princeton, he

    built the first neural network simulator.

    Minsky joined the faculty of MIT’s Department of Elect rical Engineering and

    Computer Science in 1958, and co-founded the Artificial Intelligence Laboratory

    (now the Computer Science and Artificial Intelligence Laboratory) the following

    year. At the AI Lab, he aimed to explore how to endow machines with human-like

    perception and intelligence. He created robotic hands that can manipulate

    objects, developed new programming frameworks, and wrote extensively about

    philosophical issues in artificial intelligence.

    “Marvin Minsky helped create the vision of artificial intelligence as we know it

    today,” says CSAIL Director Daniela Rus, the Andrew and Erna Viterbi Professor in

    MIT’s Department of Electrical Engineering and Computer Science. “The

    challenges he defined are still driving our quest for intelligent machines and

    inspiring researchers to push the boundaries in computer science.”

    Minsky was convinced that humans will one day develop machines that rival

    our own intelligence. But frustrated by a shortage of both researchers and

    funding in recent years, he cautioned, “How long this takes will depend on how

    many people we have working on the right problems.”

    In 1985, Minsky became a founding member of the MIT Media Lab, where he

    was named the Toshiba Professor of Media Arts and Sciences, and where he

    continued to teach and mentor until recently.

    Professor Nicholas Negroponte, co-founder and chairman emeritus of the

    Media Lab, says: “Marvin talked in riddles that made perfect sense, were always

    profound and often so funny that you would find yourself laughing days later. His

    genius was so self- evident that it defined ‘awesome.’ The Lab bathed in his

    reflected light.”

    In addition to his renown in artificial intelligence, Minsky was a gifted pianist —

    one of only a handful of people in the world who could improvise fugues, the

    polyphonic counterpoint that distinguish Western classical music. His influential

    1981 paper “Music, Mind and Meaning” illuminated the connections between

    music, psychology, and the mind.

    Other achievements inclu de Minsky’s role as the inventor of the earliest co

    focal scanning microscope. He was also involved in the inventions of the first

    “turtle,” or cursor, for the LOGO programming language, with Seymour Paper,

    and the “Muse” synthesizer for musical variations , with Ed Fredkin.

    Minsky received the world’s top honors for his pioneering work and mentoring

    role in the field of artificial intelligence, including the A.M. Turing Award — the

    highest honor in computer science — in 1969.

    In addition to the Turing Award, Minsky received honors over the years

    including the Japan Prize; the Royal Society of Medicine’s Rank Prize (for

    Optoelectronics); the Optical Society of America’s R.W. Wood Prize; MIT’s James

    R. Killian Jr. Faculty Achievement Award; the Computer Pioneer Award from IEEE

    Computer Society; the Benjamin Franklin Medal; and, in 2014, the Dan David

    Foundation Prize for the Future of Time Dimension titled “Artificial Intelligence:

    The Digital Mind,” and the BBVA Group’s BBVA Foundation Frontiers of

    Knowledge Lifetime Achievement Award.

    14. Write a short note on Zika virus and its disastrous potentialities.

    Ans . The Zika virus is a mosquito-transmitted infection related to dengue, yellow fever

    and West Nile virus. Although it was discovered in the Zika forest in Uganda in 1947 and

    is common in Africa and Asia, it did not begin spreading widely in the Western

    Hemisphere until last May, when an outbreak occurred in Brazil. Until now, almost no

    one on this side of the world had been infected. Few of us have immune defenses

    against the virus, so it is spreading rapidly. Millions of people in tropical regions of the

    Americas may now have been infected.

    Yet for most, the infection causes no symptoms and leads to no lasting harm.

    Scientific concern is focused on women who become infected while pregnant and

    those who develop a temporary form of paralysis after exposure to the Zika virus.

    At least 4,000 babies in Brazil have been born with microcephaly over just the

    last four months, and the spread of Zika virus is rapidly exploding. Here's just one

    photo showing the horrific deformations believed to be caused by Zika, carried by

    mosquitoes.

    As more reports of deformed children keep appearing, the media is freaking out, the

    CDC is freaking out and the U.S. government is freaking out, demanding urgent calls for

    yet more vaccines. Alarmingly, the very same scientists who pushed for the release of

    the genetically engineered mosquitoes that may have caused this entire are also nowcalling for more genetically engineered mosquitoes which they claim will solve this

    problem.
