Mars Sample Return Concept Illustration
This illustration shows a concept for multiple robots that would team up to ferry to Earth samples collected from the Mars surface by NASA's Mars Perseverance rover.
NASA and ESA (European Space Agency) are developing concepts for the Mars Sample Return program designed to retrieve the samples of Martian rocks and soil being collected and stored in sealed tubes by Perseverance. In the future, the samples would be returned to Earth for detailed laboratory analysis.
The current concept envisions delivering a Mars lander near Jezero Crater, where Perseverance (far left) is caching, or collecting, samples. A NASA-provided Sample Retrieval Lander (far right) would carry a NASA rocket (the Mars Ascent Vehicle), and a second lander, pictured in the background, would carry ESA’s Sample Fetch Rover (center), which is a little smaller than a golf cart. The fetch rover would gather the cached samples left on the surface by Perseverance and transport them to the Sample Retrieval Lander, where they would then be transferred onto the Mars Ascent Vehicle. Perseverance could also deliver additional samples directly to the lander. The Mars Ascent Vehicle would launch a container with the samples inside into orbit. Waiting in Mars orbit would be an ESA-provided Earth Return Obiter, which would rendezvous with and capture the orbiting sample container using a NASA-provided Capture, Containment, and Return System. This system would capture and orient the container, then prepare it for return to Earth inside the Earth Entry System.

Mars Sample ReturnMars Sample Return je plánovaná vysoce komplexní robotická mise k planetě Mars, která by měla dopravit zpět na Zemi vzorky marsovských horniny, podobně jako programy Apollo nebo Luna dopravily horniny z Měsíce. V současné době se její přípravou zabývá Evropská kosmická agentura v rámci projektu Aurora, ovšem vzhledem ke značným finančním nákladům půjde o mezinárodní misi s účastí americké NASA. .. pokračovat ve čtení
