    ORION STATUS AND MULTI-MISSION CAPABILITIESAs the Orion team prepares for the Preliminary Design Review

    (PDR) in August 2009, the design is more mature than PDR levels for

    similar complex systems, meeting stringent human rating requirements

    to ensure a safe, robust, and affordable vehicle to address mission

    needs within and beyond Low Earth Orbit(LEO)Human exploration requires going beyond Low Earth Orbit.

    Human exploration requires a destination beyond our own making,

    such as the Moon, asteroids, or Mars. Exploration is discovering the

    unexpected, exploring the unknown, and expanding the range of hu-

    man endeavors. The Orion spacecraft provides the ability to stay in

    space for 210 days and to re-enter at the velocities typical of lunar orasteroid missions. It is a highly mass efficient, safe, spacecraft config-

    ured for trans-LEO missions and also capable of transporting humans

    to the ISS. Therefore, it is the only human spacecraft currently con-templated that can do human exploration. Other human spacecraft,

    planned to be commercial, cannot perform the human exploration mission. Orion, on the other hand, in addition to human ex-

    ploration missions can do the LEO human missions envisioned by the commercial community and other LEO missions as well.

    Key Messages

    Orion Design is MatureOrion hardware is being

    qualified to be safer, more reliable, and more op-

    erable than the Shuttle and is approved by theNASA Crew Office

    Orion Design is RobustOrion is designed to be

    easily adapted to architecture changes and the

    schedule can be accelerated to minimize the gap

    following Shuttle retirement

    Orion is Capable, Flexible and Affordable, ena-

    bling U.S. Leadership in Human Space Flight

    Orions multi-mission capability and adaptability

    will enable LEO missions and exploration beyond

    Low Earth Orbit

    Orion Design is MatureThe design maturity of the Orion vehicle far exceeds the maturity of the Apollo and Shuttle designs at PDR, according to

    engineers and experts who worked on the Apollo and Shuttle programs. This maturity has been achieved with an unprecedented

    emphasis on safety, reliability, operability, and affordability in close coordination with the NASA Safety and Astronaut offices.

    The requirements and design embrace lessons learned from the Columbia accident report findings regarding loss of crew and

    loss of mission, with a focus on design for survivability. The Orion team is adhering to rigorous human rating requirements.

    Early quantitative safety and mission success analysis and demonstrations have enabled risk identification to support weight

    optimization resulting in sixty design improvements. Orions process for minimizing loss of mission probability for a 210 daymission has resulted in a spacecraft that is currently 8 times safer than the Shuttle with a target of achieving a minimum of 10

    times better than the Shuttle.The NASA Constellation program manager recently commended the Orion teams safety analysisstating, We have used this analysis to great effect and have a great vehicle heading into PDR. In addition, a standing review

    board serves as an independent review team to routinely assess design maturity, technical issues and risk. At a recent NASA

    Independent Aerospace Safety Advisory Panel (ASAP) public meeting, the ASAP commented on the Constellation Programs

    process for what they call the design for minimum risk This process incorporates an event-driven reduction in risk so thatresidual risk is both controlled and documented, with retirement taking place

    only after a specific event is successfully completed. The advanced design

    maturity of Orion serves to greatly reduce program technical, schedule, and cost

    risk as the program moves forward to Critical Design Review (CDR).

    The Orion project takes advantage of the expertise of all 10 NASA fieldcenters and includes a diverse industry team led by Lockheed Martin and

    supported by major subcontractors and small businesses. The NASA/Industry

    team benefits from the highly skilled aerospace workforce from across thecountry enabling broad public outreach and constituent support.

    Although the first missions for Orion will deliver crew and cargo to the

    International Space Station, lunar capability is being designed into Orion from

    the outset. The crew capacity requirement recently was optimized from six to

    four with a positive impact resulting in an initial Orion configuration that meetsboth Space Station and Lunar mission requirements, thereby reducing testcomplexity, schedule and budget concerns. The system architecture and volume

    allows for later modifications to achieve a 6 person contingency crew rescue

    capability. The aerodynamics and aero-thermal characteristics of the capsuleconfiguration are well understood and proven advancements in technology are

    being integrated into the design. A block upgrade approach has been adopted

    with high Technology Readiness Level subsystems used now for near term

    LEO missions with a path to graceful continuous product improvement. Any

    slips in Orion's Initial Operational Capability (IOC) have been primarily a resultof budget realities rather than design challenges.

    Risk reduction testing of critical subsystems has been ongoing with no technical drivers identified. Features are being in-

    corporated into the design to maximize mission success and crew safety. For example, the propulsion system is dual fault toler-

    ant for lunar return; the crew module will be fully operational using only one of its two solar arrays; and the crew module struc-

    ture has crumple zones designed to enable safe contingency land landings. Many components and subsystems have already

    completed development testing. Environmental Control and Life Support Systemcomponentshave been bench tested and someof the Guidance, Navigation and Control hardware and software are being flown in simulation labs using Test-Like-You-Fly

    principles. The Crew Module has undergone buoyancy testing. An operational Launch Abort System has been assembled and is

    being prepared for a launch pad abort test at White Sands Test Facility later this year. Sixty-one of eighty-three planned windtunnel tests have been completed. The docking system hardware and software is undergoing validation in a specially designed

    simulation facility. Fourteen successful parachute drop tests have been completed. Crew Module avionics components have

    been lab tested and will fly later this year on the launch pad abort test at White Sands Test Facility. Infrastructure, such as the

    Kennedy Space Centers Operations and Checkout (O&C) facility; NASA and industry test labs; and White Sands have been

    activated and are being prepared for test, production and operations. The photographs below show some of the Orion hardwarebefore, during, and after testing. Photos Courtesy of NASA

    The Orion development and test program is designed to accommodate current NASA funding and risk levels. While sig-

    nificant acceleration of the IOC would be difficult, the following items are examples of program changes that are being evalu-

    ated that would result in building additional schedule margin and confidence in meeting the early 2015 IOC:

    1. Changing the Systems Qualification test to a Flight Qualification test that includes autonomous docking to the ISS

    2. Enabling flight qualification through additional subsystem test and verification, including environmental testing andhuman-in-the-loop testing

    3. Adding another CEV Avionics Integration Lab (CAIL) test facility to eliminate lab test bottlenecking

    4. Starting production immediately and adding ground operations and production pathfinders to shorten the timeline tolaunch

    5. Expediting transfer of ground support equipment from White Sands Test Facility to Kennedy Space Center to support

    launch operations

    6. Deferring additional lunar-unique requirements/verification could also help accelerate the current IOC date

    If additional funds are made available, an improvement in schedule margin and the potential to accelerate the current IOC is

    possible.

    Orion Design is Robust

    Orion is being designed for the harsh environments beyond LEO resulting in a versatile

    vehicle suitable for missions within and beyond LEO. While the Crew Module is being de-

    signed for four crew members and will provide anytime crew rescue from the ISS, Orion is

    also designed to operate autonomously in close proximity to the ISS and can provide ISS re-boost and cargo de-orbit capability.

    A smart" Service Module can

    provide cargo delivery capabilities

    similar to what the Shuttle delivers

    today. This version of the service

    module can perform repeated tug

    missions capturing payloads

    located in low Earth orbit for

    delivery to the ISS or other orbits.

    Currently, the program baseline is to qualify

    Orion for both a two propellant tank and a four

    propellant tank version. By flying only two of itsfour propellant tanks, Orion can use the additional

    volume to perform ISS resupply missions for un-

    pressurized cargo. Additionally, the Crew Modulecan deliver and return pressurized cargo depending

    on the number of crew aboard Orion. This cargo

    concept can deliver approximately 1,800 lbs of

    pressurized and unpressurized cargo every crewed

    mission (four crew), or approximately 3,600 lbs of

    cargo per year at little or no additional cost. This is approximately 17% of the 22,000lbs requirement for ISS servicing in 2015, leaving ample opportunities for commer-

    cial cargo supply for the ISS. Orion could also provide 100% of ISS annual cargo

    requirements at a cost equal to or less than the current commercial approaches to sup-plement planned commercial systems. This concept employs an upgraded autono-

    mous Orion Service Module as a tug once the primary ISS mission is complete and

    after the Crew Module has been delivered

    to its de-orbit target. Using low cost

    launch vehicles that do not have ISS-qualified transfer stages to deliver cargo

    to LEO, the autonomous Orion Service

    Module can capture the cargo in LEO then deliver it to the ISS with its sparepropellant capacity.

    Currently designed to transport

    four astronauts to the moon,

    Orion has considerable

    capabilities for missions in low

    Earth orbit. Its first mission

    delivers four astronauts to ISS.

    using the existing Crew Module for

    pressurized cargo and the Service

    Module for un-pressurized cargo.

    In addition to providing cargo services in conjunction with Orions nominal

    ISS missions, the upgraded autonomous Service Module as described above couldbe launched to deliver 30,000 lbs of unpressurized cargo including additional nodes,

    large spares and Orbital Replacement Units (ORUs) if the ISS continues to operate

    beyond 2016. With spare propellant capacity, even in the two tank version of theService Module, the ability exists to provide ISS re-boost reducing reliance on the

    International Partners providing this service. In addition, when it is necessary to

    deorbit the ISS, Orion can provide this capability using a full propellant load in a

    four tank version.

    Orion can support NASAs Science Mission Directorate by hosting payloads

    and delivering or servicing spacecraft. A remote manipulator system can be in-

    stalled in one of the cargo compartments and on-orbit servicing for the ISS and

    other spacecraft can be performed. A science payload or observation instrument

    can be installed in one of the cargo compartments and the Service Module can

    serve as a science or observation platform after the nominal crew delivery mission

    is complete. Since the baseline design mission duration for the Service Module is

    210 days at the ISS, there is ample time for a variety of science experiments. Useof all four propellant tanks in the Service Module could provide additional delta V

    (approximately 600 meters/second), thereby allowing the Service Module to

    operate as a space platform or a space tug for non-functioning satellites.

    The Orion Service Module can be

    used to transport and deliver

    small secondary payloads into

    orbit for science, defense or

    university missions.

    A pair of Orions can be launched for a six-month mission to a Near Earth

    Object (asteroid) as early as 2018. The two-Orion configuration provides

    additional habitat volume, provisions, propellant and redundancy without the need

    for development of any new

    Constellation elements. Thiscould provide an early opportunity

    for an operational exploration

    mission prior to a lunar missionwhile supporting NASAs high

    priority science objectives and serving as a pathfinder for Mars missions,

    thereby validating Orions design for long duration deep space missions. An

    Orion crewed mission to libration points could provide a servicing capability for

    the James Webb Space Telescope or other science pl

    Orions considerable capabilities are a

    result of its design to operate beyond low

    Earth orbit in a variety of extremely

    demanding and harsh environments.

    Currently, Orion is the only human rated

    vehicle that can perform missions to the

    moon, to nearby asteroids and other

    destinations in our solar system.

    atforms.Orion is highly configurable

    with the addition of mission kits to

    perform the various missions de-scribed above. Since it is already

    being qualified for a four-tank and

    a two-tank Service Module con-

    figuration, a range of missions anddestinations is possible while

    maintaining the ability to easily

    adapt to potential changes in the

    overall Constellation architecture.

    Modified to include a robotic arm,

    Orion can support humanservicing missions to large space

    telescopes such as Hubble.
