The persistent rover is preparing to dig up some Martian rocks, and mission scientists have seen evidence of ancient flash floods in Dry lake bottoms where the rover landed. NASA shared a fileI know Updates And more at a press conference today In the Jet Propulsion Laboratory in Pasadena, California.
Perseverance landed on Mars in VibroI see and his Official scientific mission started in june, after operational checks on tools and Historical flights taken By helicopter ingenuity. Perseverance is tasked with exploring Mars’ Jezero Crater, a former site Lake that NASA scientists hope to contain Fossilized evidence of Martian life. So far, the Perseverance has covered a distance of about 1 km (0.62 miles), Photograph the fun rock formations along the way. These formations shed light on the geological history of the Red Planet, and some are promising sites to search for. Biometrics (evidence of life), which researchers speculate is possible you look like Stromatolites encased in ancient rocks on Earth. In the end, the rock samples collected by the rover will be withdrawn Through another mission and fetch Down to Earth – First material that will It can be retrieved from Mars.
Perseverance was getting closer Mars will miss him, which is a dangerous stretch of sand dunes that a rover can easily reach stuck b. The significant improvement in the vehicle’s AI system means the rover can think about where it’s going next while driving, said Olivier Tobet, rover’s augmented navigation team leader, a big step beyond the cruising system. From previous touring vehicles.
All along, Perseverance has been conducting technology demonstrations that will inform future missions. Another show besides creativity was MOXIE, where perseverance produced a small amount of oxygen on the surface of Mars, which huge effects آثار to human ambitions outside the Earth. “This experiment fuels these future missions where we want to extract oxygen, that we would like to use for human astronauts to breathe and even launch vehicles,” Jennifer Trosper, director of the Perseverance Project, said during the day. Press Conference.
The rover’s final destination is called the Three Forks, which delineate a dry river delta set off from Jezero. On the way, you’ll visit several points of interest, including Crater Floor Fractured Rough, the first sample site. NASA isn’t sure if the broken ore is igneous or sedimentary, and the answer will tell scientists how Jezero formed And what clues about life it could contain. Perseverance scientists expect that the bottom of the lake will contain some of the oldest rocks that the rover will have a chance to look at. KissAdvertisement to the river delta.
“One of the hypotheses we’re trying to test is that the lake that once filled Jezero has not only existed once, but gone through multiple periods of fullness, dryness, and fullness again,” said Ken Farley, Perseverance Project Scientist at Caltech, during Press conference. “This is very important because it means that we will have multiple time periods where we can learn about environmental conditions on Mars, and we have multiple time periods where we can look for ancient life that might have existed on a planet.”
Farley He said that photographs taken by the Perseverance indicate that ancient Jezero Lake had different water levels at different times, and that scientists have seen evidence that the ancient floods moved dramatically. rocks across the delta. One of the greatest points of interest so far on the mission is a rocky outcrop south of the probe’s landing site nicknamed Artube, after a river in southern France. Artuby appears to be a petrified Martian clay, which is exactly the stagnant, undisturbed m type.From the ancient lake that NASA wants to investigate.
For sampling, the rover will first scrape the surface of the rock To clean them of any hidden elements, such as Martian dust. The rover then extracts core from the rocks and seals it in a sampling tube inside the rover’s abdomen. This tube will eventually be included in a sample bunker that, if all goes well in the next decade, will be brought to Earth by another spacecraft.
“A lot of what we’ve been doing lately on the ground as well as on the car is preparing for that first sample,” Trosper said. “We’re ready to take samples… We expect to have that first sample within the first few weeks of August.”
While Perseverance has not yet sampled any rock, it has processed one of five Witness tubes. Witness tubes are similar to specimen tubes, but they contain materials that detect contaminants. Witness tubes are opened and sealed for sampling of the local Martian environment before any rock is extracted, so that when all tubes are returned to Earth, all tubes are returned to Earth, NASA scientists will Know if any mundane Contaminations were present during sample collection. There are 38 other tubes for sampling – this 38 opportunities for us Earthlings to see what Mars is made of and how it owns the planet changed, and what, If something, once lived there.
Finally, the upcoming Perseverance project is very ambitious. Samples are expected to arrive, said Thomas Zurbuchen, NASA associate director for science on Earth by the early 2030s.
