Space Exploration

Space Exploration
Space is explored in two ways;
– by studying it from Earth using powerful telescopes.
– by launching spacecraft to get a closer view.

Space Exploration

  • most space exploration is by unmanned space probes.
  • first pictures of the far side of the Moon were sent back by the Luna 3 space probe on 7th October 1959. (more photos of the first pictures of the Moon.)
  • manned missions have only reached as far as the Moon and no one has been back there since 1972.
  • NASA – Apollo astronauts took three days to reach the Moon.
  • a journey to the nearest star; Alpha Centauri by a Space Shuttle would taken 80,000 years.
  • some spacecraft on long voyages of exploration may be driven along by nuclear power.
  • many probes have never come back from from another planets.
