First Landing on The Moon


Since December 1972, no one has walked on the moon. Among the first steps of Neil Armstrong on the moon and those of his compatriot Eugene Cernan three years later, only twelve astronauts have had the privilege of treading an alien soil ... And yet, the "giant leap for mankind "fire Neil Armstrong was the beginning of an era when travel and distant conquests were becoming commonplace. And for good reason! The feat Armstrong and her fellow Apollo 11 had taken place thirteen years after the putting into orbit the first artificial satellite - Sputnik in 1957 - and sixty-six years after the first flight of the Wright brothers. Progress were to continue at this pace.

"NASA wants to see beyond. So that as if seized with enthusiasm, officials say the next step in human space exploration must be a landing on Mars, Space Administration has signed its first contracts for the construction of a space station and the establishment of a shuttle system between Earth and space, "wrote Le Monde on the front page, July 26, 1969. the case was heard: from to Step outside of our country and stay would be as simple as taking a plane. Since then, hundreds of astronauts have certainly left Earth for a few days or a few months; more recently, wealthy tourists could imitate them. But never again exceeded the suburbs of the Earth.

What has happened since? Of course, one of the motivations of Americans, the Cold War was to outdo the Soviets after they have blown past their politeness putting Sputnik into orbit. This rivalry between the two blocs allowed to pass to the opinion of the public spending huge money although they were justified by the major technological advances that have resulted from the conquest of space.

Return to the Moon, Mars or conquer venture on an asteroid undoubtedly bring a lot of new discoveries that have their utility for the common man - NASA has listed, as recalled by a Swiss scientist on his blog. By initiating the Constellation program in 2004, George W. Bush launched a new era of space exploration to Mars in sight via the Moon. Alas, the economic crisis is over there and his successor as head of the United States had to abandon the project.

The time is realpolitik. We hardly talk about "space race" but to "exploration". And the exploration of a part of the universe is now done remotely. The latest example, the first laps of Curiosity on Mars. A project to 2 billion euros against 98 billion for the Apollo program. The probe is already at work, transmitting fantastic images with Earthlings we are, so that we always fear the effects of a round trip of 500 days to the Red Planet on the body and mind of a team of astronauts.

The cost of Curiosity Mars rover launched in August, compared to other space exploration programs.
Nevertheless, other nations are already in position to send in turn, men - and without doubt, the first woman - to the moon. To this end, China has already sent two probes (Chang'e 1 and 2) around our satellite. The next step is planned for 2013: Chang'e 3 mission should include the landing of a module responsible for scientific analysis.

This will be the first moon landing in China, which is gearing up to establish itself as a member of the exclusive club of space powers. A subsequent mission provides, for its part, the return of a lunar probe on Earth. The program is then supposed to culminate in sending men to the moon.
