The plan is similar to but less technologically challenging than the original architecture that was ruled out because of high costs and a sample return in the 2040 timeframe. Option one would cost ...
The orbiter would capture the capsule containing the samples, propel itself out of Mars’ orbit and carry the sample the rest of the way to Earth, according to NASA.
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).
A photomontage shows tubes containing samples from Mars, as collected by NASA's Perseverance Mars rover. The agency's Mars Sample Return Program plans to bring these samples back to study them in ...
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]
Later, other sample-return missions failed: Kosmos 300 and Kosmos 305 in 1969, Luna E-8-5 No. 405 in 1970, Luna E-8-5M No. 412 in 1975 had unsuccessful launches, and Luna 18 in 1971 and Luna 23 in 1974 had unsuccessful landings on the Moon. [13] In 1970, the Soviet Union planned for a 1975 first Mars sample-return mission in the Mars 5NM project.
The four finalists were Phoenix, MARVEL, SCIM (Sample Collection for Investigation of Mars), and the ARES ("Aerial Regional-scale Environmental Survey") Mars airplane. [17] 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).
The move to redesign the mars sample return strategy comes after a NASA-commissioned independent review concluded last September that the program was hindered by "unrealistic budget and schedule ...
