(Seoul = Yonhap News) Reporter Nam-seok Eom = The American Mars rover ‘Perseverance’ managed to collect nuclear samples by drilling a hole in the rock after one failure.

The samples will be sealed and stored on the rover’s ship, and will be returned to Earth for detailed analysis along with more than 40 other soil and rock samples to be made.

Perseverance chief engineer Adam Stelltzner tweeted on the 2nd (local time), “It’s a little tricky to say, but a very complete nuclear sample is secured.”

According to the National Aeronautics and Space Administration (NASA), Perseverance drilled a hole in the rock on the 1st and took a sample the size of a finger, and sent evidence photos clearly showing the rock sample in a titanium tube (tube). ).

However, the rock sample is not visible in the photo taken and transferred to the vertical holding, so there is no residue left on the cap of the titanium tube and it was shaken 5 times for 1 second. I decided to go ahead and receive more.

It is said that the new image that has been filmed will be available on the morning of the 4th.

The Perseverance took the first rock sample on the 6th of last month and drilled a hole in the rock, but the rock was not hard and brittle, so it could not be contained in the titanium tube.

Since then, the rover has been collecting monsters from new rocks about 800 feet away.

NASA plans to send a spacecraft built together with the European Space Agency (ESA) in the early 2030s to pick up these monsters and bring them back to Earth.

By analyzing these samples with advanced ultra-precise equipment that the rover could not bring to the field, it is expected that it will be possible to reliably determine the existence of ancient life on Mars and understand geological history and climate. The information gathered will be used to prepare for a manned mission to Mars.

The place where Perseverance took the sample is an example of a landing site, and the ridge protruding from the bottom of the crater is called ‘Citadelle’. It is predicted that the rock will be harder than where the first sample was taken and would not break during the sampling process.

Perseverance is an example that is assumed to be an ancient delta into which rivers flowed in the future.

Ingenuity, originally brought to test the feasibility of helicopter operations in the thin atmosphere of Mars, has been reported to help Perseverance’s exploration activities by performing better than expected.

In an email interview with the New York Times, Dr. Kenneth Parley, a geochemistry professor at the California Institute of Technology involved in perseverance operations, planned to send a robber to check the image of the Mars orbit, because it was important, but the Injury’s close-up image showed him concluding that it was not special, stating, “It saved a lot of time for the perseverance to control it personally.”
