The year 2008 contained several significant events in spaceflight, including the first flyby of Mercury by a spacecraft since 1975, the discovery of water ice on Mars by the Phoenix spacecraft, which landed in May, the first Chinese spacewalk in September, and the launch of the first Indian Lunar probe in October.
Five carrier rockets made their maiden flights in 2008; the Ariane 5ES, Long March 3C, Zenit-3SLB, PSLV-XL, and the operational version of the Falcon 1, with an uprated Merlin-1C engine. The first Vietnamese and Venezuelan satellites, Vinasat-1 and Venesat-1 respectively, were launched in 2008, while a failed Iranian launch was reported to have been that country's first indigenous orbital launch attempt. In September, SpaceX conducted the first successful orbital launch of a privately developed and funded liquid-fuelled carrier rocket, when the fourth Falcon 1 launched RatSat, following previous failures in 2006, 2007, and August.
