2008 in spaceflight

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.

Overview

The internationally accepted definition of a spaceflight is any flight which crosses the Kármán line, 100 kilometres above sea level. The first recorded spaceflight launch of the year occurred on 11 January, when a Black Brant was launched on a suborbital trajectory from White Sands, with the LIDOS ultraviolet astronomy payload. This was followed by the first orbital launch of the year on 15 January, by a Sea Launch Zenit-3SL, with the Thuraya 3 communications satellite. The launch marked the return to flight for Sea Launch following the explosion of a Zenit-3SL on the launch pad the previous January during an attempt to launch the NSS-8 satellite.

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. These were all derived from existing systems. The Blue Sparrow and Sejjil missiles also conducted their maiden flights, and the ATK Launch Vehicle made its only flight, but was destroyed by range safety after it went off course. In November, the baseline Proton-M was retired in favour of the Enhanced variant, first launched in 2007.

2011 in spaceflight

The year 2011 saw a number of significant events in spaceflight, including the retirement of NASA's Space Shuttle after its final flight in July 2011, and the launch of China's first space station module, Tiangong-1, in September. A total of 84 orbital launches were conducted over the course of the year, of which 78 were successful. Russia, China and the United States conducted the majority of the year's orbital launches, with 35, 19 and 18 launches respectively; 2011 marked the first year that China conducted more successful launches than the United States. Seven manned missions were launched into orbit during 2011, carrying a total of 28 astronauts to the International Space Station. Additionally, the Zenit-3F and Long March 2F/G carrier rockets made their maiden flights in 2011, while the Delta II Heavy made its last.

Overview of orbital spaceflight

A total of 84 orbital launches were attempted in 2011, with 78 being reported as successful; 80 launches reached orbit. 35 launches were conducted using Russian and former Soviet rockets, whilst China launched 19 rockets, and the United States launched 18. Europe conducted five launches, India and Japan launched three rockets each, and Iran conducted one launch.

2009 in spaceflight

Several significant events in spaceflight occurred in 2009, including Iran conducting its first indigenous orbital launch, the first Swiss satellite being launched and New Zealand launching its first sounding rocket. The H-IIB and Naro-1 rockets conducted maiden flights, whilst the Tsyklon-3, Falcon 1 and Ariane 5GS were retired from service. The permanent crew of the International Space Station increased from three to six in May, and in the last few months of the year, Japan's first resupply mission to the outpost, HTV-1, was conducted successfully.

Overview

The internationally accepted definition of a spaceflight is any flight which crosses the Kármán line, 100 kilometres above sea level. The first spaceflight launch of the year was that of a Delta IV Heavy, carrying the USA-202 ELINT satellite, which launched from Cape Canaveral Air Force Station at 02:47 GMT on 18 January. This was also the first orbital launch of the year.

On 2 February Iran conducted its first successful orbital launch, when a Safir was used to place the Omid satellite into low Earth orbit.
