Mars flyby
Data collected from Mariner 4's flyby on a modern map
A Mars flyby is when a spacecraft passes near the planet Mars, but does not enter orbit or land on it.[1] Unmanned (no humans on board) space probes have used this method to collect data on Mars[2] and other worlds. A spacecraft that is built for a flyby is also known as a "flyby bus" or "flyby spacecraft".[3]
List of Mars flybys
- Dawn, closest approach (2009) was 549 km.[4][5]
- Rosetta[6] within 250 km[2]
- Nozomi[7]
- Mariner program spacecraft
- Mariner 4 (1965, the first successful Mars flyby), Mariner 6, and Mariner 7 returned data from Mars flybys
- Mars program spacecraft
- Two Mars flyby attempts were made in 1960 under Mars 1M (Mars 1960A and Mars 1960B).
- The third attempt at a Mars flyby was the Soviet Mars 2MV-4 No.1,[8] also called Mars 1962A or Sputnik 22, which launched in 1962 as part of the Mars program.[9] but it was destroyed in low Earth orbit due to rocket failure.[10]
- Mars 1 also launched in 1962 but communications failed before it reached Mars.[11]
- Mars 4 achieved a flyby in 1974 and detected a night-side ionosphere, although by that time Mars was already orbited by other spacecraft.[11]
- Mars 6 and 7 were Mars landers carried by flyby buses.[12]
