Spaceflight, Space flight means the use of space technology to achieve the flight of spacecraft into and through outer space. A space flight begins with a launchwhich provides the force to push from the gravity which sends the space craftto the surface of the earth.
People began travelling to space in 1961 in small spacecrafts which arecalled capsules, which were launched from earth by using powerful rockets.How do humans survivein space? There is no availability of oxygen, waterand many other human needs .So all the air craft with crew carry a life –support system. This supplies air to breathe. This system also includes theequipment to keep the air at comfortable temperature. This system also removescarbon dioxide and odours. AIRCRAFTS GENERALLYALLOWING FOR SPACETRAVEL (HUMAN FLIGHT): The firsthuman flight was launched by the SovietUnion on 12 April 1961 as a part of the Vostok program, with cosmonaut Yuri Gagarin aboard. The first human flight is made bySoviet Union (Russia) in 12 April 1961 and named as Vostok1.
Program Start date Notes Apollo program 1961 Brought first human to the Moon Skylab 1973 The crewed missions only took place in 1973 and 1974; first American space station Apollo–Soyuz Test Project 1975 Joint with Soviet Union (Now Russia) Shuttle-Mir Program 1995 Russian partnership ENTERTAINMENT AND FREETIME IN SPACE: The astronauts can bring someof their own belongings with them. They can spend their leisure time in thesame way that they are spending on Earth by reading their favourite books,listening to music, etc.. Also, since the Earth and stars they’re able to seefrom the Space Shuttle’s windows are so beautiful, the astronauts can spendtheir time by enjoying the view and taking pictures of stars planets etc.. Living in space is not just doing only work and nothing to play.Astronauts like to have fun, too.
If you’re staying on the International SpaceStation for a few months, it is certainly okay to look out the window, playwith your food or tease your crewmates once in a short time. Fun is anessential component to the quality of life. WHAT IS THE OUTER SPACE LIKE? Ø We usually don’t notice, but also air havesome weight, and it is held onto the surface by the earth’s gravity.Ø Higher than 400 km abovethe ground, where the International Space Station (ISS) is flying, there isalmost no air. The state where no air is present is called as vacuum.
And Spaceis a vacuum.Ø Generally, the altitudes of 100 km or above areconsidered as outer space. Where humans can’t live without spacesuit.Ø In the higher elevations, the amount of air isless. That is why the air becomes less as higher as you go up.
Ø In a vacuum, humans cannot live without wearing aspace suit. Ø As the space a is vacuum there is no air tobreathe in Space.
