But the data it sent to earth showed that the first sampling campaign failed to collect any rocks < p > Figure 1: photos taken on August 6, 2021 show that NASA's perseverance Rover drilled holes on the surface of Mars for the first time < / P > < p > perseverance carried 43 titanium sample tubes. At present, it is exploring Jezero crater. The rover will collect samples of rock and weathered stone (gravel and dust) there for future return to earth for analysis. Thomas Zurbuchen, deputy director of NASA, said: "although this is not the 'hole in one shot' we want, there are always risks in exploring space. I believe that we have the right team to solve this problem, and we will persevere in seeking solutions to ensure future success. " < p > perseverance's sampling and storage system uses hollow coring bits and percussive bits at the end of its 7-foot (about 2-meter) long manipulator to extract samples. Telemetry from the rover showed that during the first sampling attempt, the two drill bits were joined as planned, and the sample tube after coring was processed as planned. Jessica Samuels, Mars ground mission manager of NASA Jet Propulsion Laboratory, said: "the sampling process is automatic from beginning to end. After the probe is placed into the collection tube, it can measure the volume of the sample. If the sample is in the test tube, the probe will display. " < p > the mission of perseverance is to set up a response team to analyze the data. The early action will be to use the Watson (wide-angle terrain sensor for operation and engineering, located at the end of the manipulator) imager to take close-up photos of the borehole. Once the team has a better understanding of what happened, they will be able to determine when to schedule the next sample collection attempt < p > Jennifer Trosper, project manager of JPL's perseverance, said: "the initial idea is that ATC is more likely to be the result that the rock target does not respond in the way we expect in the coring process, rather than the hardware problem of the sampling and storage system. In the next few days, the research team will spend more time analyzing the data we have to solve the root cause of sampling failure. " < p > NASA has encountered similar problems in sample collection and other activities on Mars before. In 2008, the soil sampling of Phoenix probe was successful after many attempts. Curiosity drilled harder and more brittle rock than expected. Recently, the heat probe on the insight lander, known as the mole, failed to penetrate the Martian surface as planned < p > perseverance is currently exploring two so-called "geological units", including the deepest and oldest exposed bedrock layer of yezelo crater and other interesting geological features. The first unit is called "crater fracture roughness", which is the bottom of yezelo crater. The adjacent unit, called "s é í TAH", contains Martian bedrock and is also the site of ridges, layered rocks and sand dunes < p > recently, the perseverance scientific team began to use the color images on the ingenuity Mars helicopter to help detect potential areas of scientific research significance and find potential dangers. On 4 August, wit completed its 11th flight to a distance of about 1250 feet (380 meters) from its current position in order to provide s é í TAH with aerial reconnaissance information < p > perseverance initially planned to explore Mars for hundreds of days, and the mission was completed when it returned to the landing site. So far, the perseverance has traveled 2.5 to 5 kilometers and may have been filled with up to eight sample tubes. Next, it will turn north and then west to its second scientific activity site, the delta of yezelo crater. There is a fan-shaped relic formed by the confluence of an ancient river and a lake, which may be rich in carbonate minerals. On earth, this mineral can preserve fossil signs of ancient microorganisms One of the key objectives of the perseverance Mars mission is astrobiology, including looking for signs of ancient microbial life. The rover will describe the geological and past climatic characteristics of Mars, pave the way for human exploration of the red planet, and will become the first mission to collect and store Martian rocks and weathered layers. NASA's follow-up mission will cooperate with the European Space Agency to launch a probe to Mars to collect these sealed sample tubes from the Martian surface and bring them back to earth for in-depth analysis（ Small) < / P > < p >
