A spacecraft is a craft or machine designed for spaceflight. Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, planetary exploration and space tourism. Spacecraft and space travel are common themes in works of science fiction. On a sub-orbital spaceflight, a spacecraft enters space and then returns to the surface, without having gone into an orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers, while those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific research are space probes. Robotic spacecraft that remain in orbit around a planetary body are artificial satellites. Only a handful of interstellar probes, such as Pioneer 10 and 11, Voyager 1 and 2 , and New Horizons, are currently on trajectories that leave our Solar System. From Wikipedia under the

What type of friction do the air molcules it is bombarded create? Q. Please help these are the answers I have been given to choose from: a huge amount of heat. Astronauts are protected from this by thermal insulation on the outside of the spacecraft, gravity to force the spacecraft back into space, a soft and easy landing. Thanks!

Q. Ok so I looked everywhere 4 this answer, didnt find it...Ok so like how did scientists figure how to build a spacecraft? And how did they figure out how to support life? Asked by Shepp - Mon Dec 7 12:44:04 2009 - - 5 Answers - 0 Comments A. Engineers build spacecraft using known facts supplies to them by scientists. They also use 100 years of experience in building aircraft, radio and electronics equipment and 50 years of experience in building space vehicles. Some things are obvious. If there is a vacuum in space, you seal the vehicle and put air inside it, this is if you expect people to be inside it. If the thing experiences severe vibration on launch, you build it to withstand vibration. Answered by Grignard Reagent - Mon Dec 7 14:32:47 2009 From Yahoo Answer Search: "Spacecraft" |
