Although earth-orbiting satellites have by far accounted for the great majority of launches in the space program, even more information on the moon, other planets, and the sun has been acquired by space probes. Also in China landed a spacecraft called chang'e 4 on the dark side of the Moon. The first crew arrived in From to , these probes confirmed the high surface temperature and thick atmosphere of Venus, discovered signs of recent volcanism and possible water erosion on Mars, and investigated Mercury. Intelligence-gathering satellites have been used to verify arms-control agreements, provide warnings of military threats, and identify targets during military operations, among other uses. Module 7: Solar System Exploration. In Lunar Prospector was crashed near the South Pole of the Moon in an attempt to find water - it didn't find any. It also measured atmospheric pressure and measured the temperature before it stopped transmitting. Module 4: Moon Base This module will look at the history of the Moon, how it was formed in relation to the Earth and how its gravity influences our planet. In August the Magellan probe went into orbit around Venus and accurately mapped the surface of the planet. Christopher C.

The first step in embarking on a long and challenging journey involves laying solid groundwork for a successful endeavor. More from Space The Apollo Program InPresident Kennedy had committed the United States to the goal of landing astronauts on the moon and bringing them safely back to earth by the end of the decade.

Space exploration benefits

While the observation of objects in space—known as astronomy—pre-dates reliable recorded history, it was the development of large liquid-fueled rocket engines during the early 20th century that allowed space exploration to become a practical possibility. Now, the view of Earth from orbit has become commonplace, but space is still changing the way we think about Earth. The first crew reached Skylab in May, At first it was hoped that shuttle flights could operate on a monthly basis, but schedule pressures contributed to the explosion of the Challenger shuttle in , when cold launch conditions led to the failure of a rubber O-ring, and the resulting flame ruptured the main fuel tank. A probe called New Horizons reached Pluto and Charon in July sending back the first detailed images. In December Pioneer 10 flew past Jupiter. Space shuttle Atlantis flew its first mission in The shuttle fleet subsequently operated on approximately a bimonthly schedule. It was crushed by the atmospheric pressure. The Mars Pathfinder and Mars Global Surveyor, both of which reached Mars in , were highly successful, the former in analyzing the Martian surface and the latter in mapping it. Soyuz 4 and 5 docked in space in Jan. Also in China landed a spacecraft called chang'e 4 on the dark side of the Moon. Venera 13 and Venera 14 reached Venus in

Second, governments were willing to take on this responsibility because of the belief that fundamental research would produce new knowledge essential to the health, the security, and the quality of life of their citizens. Visiting an asteroid will provide valuable mission experience and prepare us for the next steps—possibly for the first humans to step on Mars.

The Columbia Encyclopedia, 6th ed. Satellites and Probes Although studies from earth using optical and radio telescopes had accumulated much data on the nature of celestial bodies, it was not until after World War II that the development of powerful rockets made direct space exploration a technological possibility. The ESA Mars Express, launched in , began orbiting Mars later that year, and although its Beagle 2 lander failed to establish contact, the orbiter has sent back data. Space shuttle Atlantis flew its first mission in It analyzed the atmosphere, finding it to be almost all carbon dioxide with tiny amounts of oxygen and water vapor. No spam, we promise. Shenzhou : the series of missions which saw China become the 3rd nation into space. Stone Mountain dominates the background in this lunar scene. Meanwhile in Bruce McCandless made the first untethered space walk. Also in Luna 2 crashed onto the Moon. The Space Shuttle After the Skylab space station fell out of orbit in , the United States did not resume sending astronauts into space until , when the space shuttle , capable of ferrying people and equipment into orbit and back to earth, was launched. But those targets may not be what we need to keep Earth's ecosystems functioning, some planetary scientists fear. In May, , the Dragon made its first resupply trip to the space station, returning with experiments and other items. Space probes have also been aimed at the outer planets, with spectacular results. The history of human space flight has been dominated by the US and Russian efforts in space and was unquestionably accelerated by the cold-war rivalry between these two countries.

The satellite Sputnik circled the Earth doing little more than send back radio beeps, but it ushered in the space age. Module 5: Mars Colony In this module, students will look at the history of Mars, how it was formed, and how its position in our solar system have contributed to it becoming the Red Planet.
