Tianwen-3 (Chinese: 天问三号) is a planned Mars sample-return mission by China which would send two spacecraft (an orbiter/Earth-returner and a lander/ascent-vehicle) via two separate launches to Mars. Together, the two spacecraft will seek to obtain samples of Martian rocks and soil and then return the cached samples to Earth. [1]
In October 2009, NASA and ESA established the Mars Exploration Joint Initiative to proceed with the ExoMars program, whose ultimate aim is "the return of samples from Mars in the 2020s". [33] [34] ExoMars's first mission was planned to launch in 2018 [35] [36] with unspecified missions to return samples in the 2020–2022 time frame. [37]
A Mars sample-return (MSR) mission is a proposed mission to collect rock and dust samples on Mars and return them to Earth. [1] Such a mission would allow more extensive analysis than that allowed by onboard sensors.
Nelson said both options involve cleaning Martian dust from the tubes on the planet surface instead of on the return vehicle, and using one of the spare arms on the Mars Perseverance rover to ...
A montage of artist's impressions show the different elements of NASA's original Mars Sample Return mission architecture. A large solar-powered sample collection lander is seen at right with the ...
“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 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 ...
