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).
NASA has arrived at two ways of returning samples collected on Mars to Earth. Now, the agency will test the options to see if the cache can make it back in the 2030s.
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 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]
“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away ...
The ESA has also considered a sample return mission, one of the latest known as Martian Moon Sample Return or MMSR, and it may use heritage from an asteroid sample return mission. [57] Osiris-Rex 2 was a proposal to make OR a double mission, with the other one collecting samples from the two Mars moons. [58]
The result of NASA's last "Decadal Survey" was to prioritize a Mars sample-return mission, as Mars has a special importance: it is comparatively "nearby", might have harbored life in the past, and might even continue to sustain life. Jupiter's moon Europa is another important focus in the search for life in the Solar System. However, due to the ...
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 ...
