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 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]
NASA's mission to return samples from Mars and potentially discover the first signs of alien life has a new timeline. The samples may arrive sooner. NASA scrapped its $11 billion scheme to grab ...
Mars Sample Return is humanity’s first mission to bring scientific samples from a habitable planet back to Earth, Fox said. “We want to bring those back as quickly as possible to study them in ...
“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 ...
Planetary protection aims to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions. A sample return from Mars or other location with the potential to host life is a category V mission under COSPAR, which directs to the containment of any unsterilized sample returned to Earth.
The goal is more than 30 samples to scour for possible signs of ancient Martian life. The space agency wants to get at least some of the collected samples to Earth sometime in the 2030s for no more than the $7 billion. That would require a spacecraft that goes to Mars to get the tubes and launches off the planet.
