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]
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.
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]
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 ...
“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 troubled Mars mission's final design won't be clear until 2026. ... Anyone hoping for a clear path forward this year for NASA’s imperiled Mars Sample Return mission will have to wait a ...
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 Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002. [2] [3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit. [1]
