Less budget, rising costs impact Mars Sample Return An $11 billion price tag for the program would cause NASA to cannibalize other science programs and missions, Nelson said.
[15] They presented a notional mass budget for a concept that would launch a 9.5-metric-ton payload from Earth, including a Mars orbiter for Earth return, and a lander having a 400-kg rover and a "Mars return vehicle" that would mass over 2 metric tons. A 20-kg sample canister would arrive at Earth containing 5 kg of samples including ...
Mars Ascent Vehicle (MAV) is a two-stage, solid-fueled rocket that will deliver the collected samples from the surface of Mars to the Earth Return Orbiter. Early in 2022, Lockheed Martin was awarded a contract to partner with NASA's Marshall Space Flight Center in developing the MAV and engines from Northrop Grumman . [ 171 ]
The resulting gas flow is analyzed in the mass spectrometer with a mass range of 2–535 daltons. [1] [5] The tunable laser spectrometer (TLS) performs precision measurements of oxygen and carbon isotope ratios in carbon dioxide (CO 2) and methane (CH 4) in the atmosphere of Mars in order to distinguish between their geochemical or biological ...

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 Mars Sample Recovery Helicopters are a pair of robotic unmanned helicopters being developed by the engineers of the American company AeroVironment Inc. and proposed in March 2022 as a means of delivering Martian soil samples from the sample depots made by the Perseverance rover to the location of the Sample Retrieval Lander (SRL) that will load these samples onto the Mars Ascent Vehicle ...
