What can Spacecrafts do for you ?

• Satellite television ,Radio , and internet

• Weather forecasting • GPS

Satellite television is used to deliver television programming using signals relayed from space radio stations (e.g. DVB satellites). The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block down converter (LNB). A satellite receiver then decodes the desired television programme for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services, especially to geographic areas without terrestrial television or cable television.

• A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a crew, which is designed to remain in space for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. As of April 2016 two space stations are in orbit: the International Space Station , which is permanently manned, and China's Tiangong-1 (which successfully launched on September 29, 2011), which is unmanned most of the time. Previous stations include the Almaz and Salyut series, Skylab, and most recently Mir.

Future of space station technology

What’s Next• NASA says it will select a target asteroid

by 2019, which will be about a year before the unmanned collector spacecraft

is launched.

• Space tourism is space travel for recreational, leisure or business purposes. A number of startup companies have sprung up in recent years, such as Virgin Galactic and XCOR Aerospace, hoping to create a sub-orbital space tourism industry.

• The publicized price for flights brokered by Space Adventures to the International Space Station aboard a Russian Soyuz spacecraft have been US $20–40 million, during the period 2001–2009 when 7 space tourists made 8 space flights. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit.
