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]
