Space Flight | Week 6

Space scientists are very interested in the phenomenon of weightlessness. They have carried out extensive studies on the fact that weight of the object depends on its position relative to the centre of the earth.

Space travel means traveling through space to visit and explore other worlds. The scientists that travel to space are called ASTRONAUTS. Space flight can occur with space craft /spaceship or without human on board.

Examples of human space flight include the Russian Soyuz program, the US space shuttle program, as well as the ongoing international space station.

Examples of unmanned space flight include satellites in orbits around the earth.

In 1961, the USSR sucessfully placed the first man, Yuri Gagarin in Orbit round the earth. On 21 July, 1969, Neil Armstrong a US astronaut became the first human being to step on the moon.  The Nigerian satellite was launched in September, 2003.
