according to the current concept, NASA will launch a Mars Lander near the Jezero crater, where perseverance (left) will collect and store samples. The sample recovery lander (right) will carry NASA’s rocket (Mars ascending vehicle) and ESA’s sample collection Rover (middle) – about the size of opportunity. The sampling vehicle will collect the hidden samples and take them back to the lander for transfer to the ascending aircraft; Additional samples can also be shipped directly by perseverance. Then, the ascending spacecraft will launch a special container containing samples into Mars orbit. ESA will put a spacecraft into Mars orbit before the launch of the ascending spacecraft. The spacecraft will merge with samples in orbit and capture them before returning them to earth. NASA will provide capture and seal payload modules for the orbiter

the above artist’s concept of the proposed Mars Sample Return Mission depicts a series of steps for the spacecraft to land on Mars, a total of six (a to f). NASA and ESA are working together to propose a mission to collect Martian rock samples and bring them to earth after 2020. This illustration describes a preliminary concept, not a completed design

this series starts from the upper left corner. The deceleration parachute capsule is still connected to the cruise stage, which provides power and mobility in the process from earth to Mars

after abandoning the cruise stage, the parachute uses friction with the Martian atmosphere to slow down. The parachute protects other parts of the flight system (enclosed inside) from the heat generated when passing through the upper atmosphere

in the third step, the parachute of the spacecraft further slowed down the descent speed

after separation from the parachute and air bag, the degraded deceleration rocket is launched to control the speed of the last approach to the ground

lower demotion starts to lower the lander onto a bridge. In this final approach process, the timing of key steps is based on the radar input of spacecraft altitude and speed

in the last step, the lander — carrying a rover and an ascent — lands, the connecting rope is cut off, and the descent flies out

after landing, the rover will send the previously hidden samples to the ascender, and then the ascender will lift the samples from the surface of Mars and meet a spacecraft that will bring the samples to the earth in orbit

the above figure is a conceptual diagram of the Mars sample return mission, which shows a rocket powered downgrading, which lowers a sample recovery Rover and an ascending spacecraft to the surface. The ascending vehicle is located in a large cylinder to protect it from the harsh Martian environment. A rover with solar panels folded on its right. The liftoff will receive Martian rock samples collected by previous missions and retrieve them by the rover. It will then launch the samples into Mars orbit and rendezvous with the spacecraft carrying the samples to earth

the illustration above shows the concept of a rover that collects rock and soil samples on Mars to return to earth. The sample tube in this picture was left on the surface by the previous mission, NASA Mars 2020

the above figure shows the conceptual model of NASA’s orbital sample container, which will be used to load Martian rock and soil sample tubes, which will return to earth through Martian sample return activities. On the right is the cover; In the lower left corner is a model of the tube containing the sample. The sample container will help keep the contents below approximately 86 degrees Fahrenheit (30 degrees Celsius) to help preserve the most natural state of Martian material

as part of the Mars sample return mission, the rocket will carry a sample tube container containing Martian rock and soil samples into orbit around Mars and release it, which will then be picked up by another spacecraft. The illustration above shows the concept of a Mars ascent vehicle (left) releasing a sample container (right) at a high altitude on the Martian surface
