The Soviet Union considered a Mars sample-return mission, Mars 5NM, in 1975 but it was cancelled due to the repeated failures of the N1 rocket that would have launched it. Another sample-return mission, Mars 5M (Mars-79), planned for 1979, was cancelled due to complexity and technical problems. [14]
In the summer of 2001, the Jet Propulsion Laboratory (JPL) requested mission concepts and proposals from industry-led teams (Boeing, Lockheed Martin, and TRW). [17] The science requirements included at least 500 grams (18 oz) of samples, rover mobility to obtain samples at least 1 kilometre (0.62 mi) from the landing spot, and drilling to obtain one sample from a depth of 2 metres (6 ft 7 in).
The Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002. [2] [3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit. [1]
At the time, NASA Administrator Bill Nelson said independent reviews estimated the project would cost between $8 billion and $11 billion and that the samples may not return until 2040, which was ...
For nearly half a century, NASA has been talking an awfully good game about its much-heralded Mars Sample Return (MSR) project. As long ago as 1978, the space agency requested funding to develop a ...
Watch live as a Nasa spacecraft returns to Earth with the largest asteroid sample in history on Sunday 24 September. After a seven-year, four-billion-mile journey across space, the ambitious NASA ...
SCIM was a sample return mission that would have used a free-return trajectory and aerogel to capture Mars dust and return it to Earth [17] (see also: the Stardust mission). MARVEL was an orbiter that would have searched for volcanism as well as analyzed various components of the Mars atmosphere. [17]
But the independent review found that actual Mars sample return costs, under latest designs, would soar to as high as $11 billion and fail to deliver the specimens to Earth before 2040.
