Eight NASA probes have visited the surface of Mars, and the Mars rover perseverance will store the samples collected for the first time so that they can be brought back to earth on future missions. NASA’s will rover is getting closer to its scheduled launch date on July 30.
on December 17, 2019, engineers conducted the first driving test of the will rover at the jet power laboratory in Pasadena, California.
the rover is responsible for an important astrobiology mission, that is, to search for evidence of micro life in the history of Mars, and to explore the geological characteristics of jezerro crater. At the same time, will will will also demonstrate some key technologies for future robots and humans to explore Mars. In the course of all of these missions, will will will also collect the first samples of Martian rocks and weathered layers (mainly broken rocks and dust) for return to earth in a series of future missions.
in this artist’s vision, the United Launch Alliance’s two-stage atlas 5 launch vehicle will propel the will to the red planet. This will be NASA’s fifth Mars mission with a 60 meter high atlas 5 rocket.
“today, 51 years ago, NASA was making the final preparations for its first moon landing,” NASA director Jim bridenstein said in a video interview on July 17. “Today, we are about to usher in another milestone in our exploration: collecting samples on Mars. As we celebrate the heroes of Apollo 11 today, people in the future will probably remember everyone behind the will – not only because of what they achieved 100 million miles away from home, but also because of what they were able to do to make it happen. ”
NASA announced the Mars 2020 mission in December 2012 and confirmed that it will be launched this summer. Due to the relative position of the earth and Mars, the launch opportunity only appears once every 26 months. If perseverance fails to go to Mars this summer, the program will have to be postponed to September 2022, which will seriously affect the long-term goals of NASA’s Mars exploration program and increase the risk of the entire mission.
in planning the Mars mission, the will team faced significant challenges. The will has the most heavy load to reach Mars so far, and team members also conducted a complete test program to confirm the reliability of the parachute design. In addition, they have made a lot of efforts to improve the performance of the rover’s sample preservation system, which will be the most complex and clean device ever to go into space. Firm and indomitable will of
novel coronavirus pneumonia, the 8 x 13 cm aluminum plate will be installed on the Mars force monitor to commemorate the impact of the new crown pneumonia pandemic.
however, novel coronavirus pneumonia is the biggest challenge in all obstacles faced by the team of perseverance. The safety precautions need to be completed remotely and with huge workload. To commemorate novel coronavirus pneumonia and firm and indomitable will to health care workers from all over the world, the team has installed a 8 * 13 cm aluminum plate on the Mars rover, which is symbolized by healing and medicine. The firm and indomitable Rover novel coronavirus pneumonia is a

The snake winding pattern on it symbolizes healing and medicine to commemorate the impact of the new crown pneumonia pandemic and commends the tough will of medical staff all over the world.
at present, all major components of the Mars 2020 mission (from the parachute to the Rover) are ready. On July 7, the will rover was installed on top of the Atlas V rocket, which will be responsible for the launch mission.
“this mission requires 314 million miles (505 million kilometers) of interplanetary space after launch, and then a 7-minute terror flight to safely reach the surface of Mars,” said Lori, director of NASA’s Planetary Science Division “When we first saw the landforms of jazerro crater for the first time, we really began to realize that there was a treasure field of Science in front of us, and the game really started,” glaze said
the Astrobiology mission of the will rover will be to look for signs of ancient microbial life. It will also depict the climate and geological features of Mars, pave the way for human exploration of the red planet, and become the first planetary mission to collect and preserve Martian core and dust samples. Currently, NASA is working with the European Space Agency (ESA) to develop a follow-up mission to launch a spacecraft to Mars to bring the samples stored by perseverance back to earth for further analysis.
the disk-shaped cruise platform of Mars 2020 will Mars rover is located above the rear shell, and the power descent device and perseverance Rover are located inside the rear shell. This photo was taken on May 28, 2020 at the Kennedy Space Center in Florida.
the Mars 2020 mission is part of a larger program, which also includes lunar missions to prepare for human exploration of the red planet. NASA is conducting a space exploration program called the Artemis program, which aims to return astronauts to the moon by 2024 and establish a lasting human presence on and around the moon by 2028.
if the launch is successful on July 30, the will rover will land in jezerro crater on February 18, 2021. Determining a specific landing date and time will help mission planners better understand the light and temperature at the landing site, as well as the location of Mars orbiting satellites, whose mission is to record and relay probe data during descent and landing.
