The exploration of Mars has been an important part of the space exploration programs of the Soviet Union (later Russia), the United States, Europe, and Japan. Dozens of robotic spacecraft, including orbiters, landers, and rovers, have been launched toward Mars since the 1960s. These missions were aimed at gathering data about current conditions and answering questions about the history of Mars. The questions raised by the scientific community are expected to not only give a better appreciation of the red planet but also yield further insight into the past, and possible future of Earth.

Alexey Arkhipovich Leonov (Russian: Алексе́й Архи́пович Лео́нов), (born 30 May 1934 in Listvyanka, Kemerovo Oblast, USSR), is a retired Soviet/Russian cosmonaut and Air Force General who, on 18 March 1965, became the first human to walk in space. Leonov was selected as a member of the first cosmonaut group in 1960. His spacewalk was originally to have taken place on the Vostok 11 mission, but this was cancelled, and instead happened on the Voskhod 2 flight. He was outside the spacecraft for 12 minutes, connected to the craft by a 1.5 metres (4.9 ft) tether. At the end of the spacewalk, Leonov's spacesuit had inflated in the vacuum of space to the point where he could not reenter the airlock. He opened a valve to allow some of the suit's pressure to bleed off, and was barely able to get back inside the capsule. Leonov was to have been commander of the ill-fated 1971 Soyuz 11 mission to Salyut 1, the first manned space station, but his crew was replaced with the backup after Cosmonaut Valery Kubasov was suspected to have tuberculosis. This crew were subsequently killed when the spacecraft depressurised in space. On his next trip into space, Leonov commanded the Soviet side of the Apollo-Soyuz mission, Soyuz 19. From 1976 to 1982, Leonov was the commander of the cosmonaut team ("Chief Cosmonaut"), and deputy director of the Yuri Gagarin Cosmonaut Training Centre, where he oversaw crew training. He retired in 1991. (more...)

The next scheduled launch is the maiden flight of the ATK Launch Vehicle, which will carry the SOAREX-VI experiment on a sub-orbital trajectory. Liftoff, from LP-0B at the Mid-Atlantic Regional Spaceport (Wallops Island), is scheduled to occur between 14:00 and 17:00 on 21 August. The next orbital flight may be made by a Safir rocket, which Iran would use to carry the Omid satellite. The next scheduled manned launch will be of the Space Shuttle Atlantis, on mission STS-125, the final mission to service the Hubble Space Telescope. Launch from LC-39A at KSC is scheduled for 8 October. A webcast can be viewed on NASA TV.
