NASA is making final preparations for its Perseverance Mars Rover to collect its first Martian rock samples, which will be sent to Earth on future missions. The six-round geologist is searching for a scientifically interesting target in a part of the Jezero crater called the “Rough, Fractured Crater Floor.
This important mission milestone is expected to begin in the next two weeks. Perseverance landed in Jezero crater on February 18, and NASA launched the science phase of the rover mission on June 1, exploring the bottom of a 1.5-square-mile (4-square-kilometer) crater, which may contain the oldest and deepest exposed bedrock at Jezero.
“When Neil Armstrong collected the first Tranquility sample 52 years ago, he began a process that will rewrite human understanding of the moon,” said Thomas Zurbuchen, deputy director of science at NASA Headquarters. “I fully expect that the first Perseverance sample from Jezero Crater and subsequent samples will do the same for Mars. We are on the threshold of a new era of planetary science and discovery.
Armstrong collected the first sample flower from the moon It took 3 minutes and 35 seconds. Perseverance takes about 11 days to complete your first sample, because you have to receive your instructions. From hundreds of millions of miles away, while relying on the most complex and effective mechanism, and the cleanest mechanism ever sent into space: the sampling and buffering system.
precision instruments work together.
sequence. Sampling starts by moving and placing everything needed for sampling within reach of its 2-meter-long robotic arm. It then conducts image research so that the NASA science team can determine the exact location where the first sample was collected and a single target location in the same area for “close to science.
“The idea is to obtain valuable data about the rocks we are studying,” said Vivian Sun, a field scientific colleague at NASA’s Jet Propulsion Laboratory in Southern California: “By searching for geological twins and performing detailed in-situ analysis Take a sample. ” “In the geological surrogate, we first use a grinding bit to scrape off the top layer of rock and dust to expose a cool, weather-free surface, clean it with our gas dust removal tool, and then get closer to the proximity science installed in the turret. SHERLOC, PIXL and WATSON instruments.
SHERLOC (Raman and Luminescence Scanning for Organics and Chemicals for Habitable Environments), PIXL (Planetary X-ray Rock Chemistry Instrument) and WATSON (Wide Angle for Operation and Engineering Sensor The camera will provide a chemical and mineral analysis of the wear target. Perseverance’s SuperCam and MastcamZ instruments are located on the rover’s mast and will also participate. SuperCam emits a laser on the worn surface, measures the resulting plume using a spectrum and collects other data, while MastcamZ captures high-resolution images.
These five instruments work together and will be able to perform unprecedented analysis of geological materials at the construction site.
“Once our pre-search science is complete, we will limit the rover mission to the sun or Mars day,” Sun said. “This will allow the rover to be fully charged for the next day’s events.” At the beginning of sampling day
, the sample processing arm in the adaptive cache assembly retrieves the sample tube, warms it up, and inserts it into the bit. A device called a rotary drill rig transports the tubes and bits to the rotary drum rig on the Perseverance robotic arm. The rig will then drill through the geological “twin” of intact rock to study the previous sun, filling it with a core sample roughly the size of a piece of chalk. The
Perseverance arm will then move the bit and tube assembly back onto the bit conveyor and then transfer it to the adaptive damping assembly, where the sample volume will be measured, photographed, sealed, and stored. The next time you see the contents of the sample tubes, they will be analyzed in a clean room on Earth using scientific instruments that are too large to send to Mars.
“Not all samples collected by Perseverance will be used to explore ancient life, and we don’t want the first sample to provide clear evidence in any way,” said Ken Farley, Perseverance project scientist at the California Institute of Technology. “Although the rocks in this geological unit are not excellent time capsules for organic matter, we believe that they have been around since the formation of the Jezero Crater and are of incredible value in filling the gaps in our geological understanding of the region. Urgently needed… to know if we have ever found life on Mars.” More information on
One of the main goals of the Perseverance Mars mission is astrobiology, including the search for signs of ancient microbial life. The rover will describe the geological features of this planet. The weather in the past will pave the way for humans to explore the red planet. It will be the first mission to collect and store Martian rocks and weathered layers. The
Perseverance Mars 2020 mission is the first step of NASA’s Mars sample return activity. NASA’s follow-up mission is currently being developed in cooperation. Help prepare for exploration n humans from the red planet.
JPL is managed by the California Institute of Technology in Pasadena, California for NASA.
