Mars: Perseverance collects samples rich in organic compounds



the search for perseverance signs of life in March increased significantly. In recent months, the rover has explored the remains of an ancient river delta inside Jezero Crater, where a large lake was located billions of years ago.


The presence of this delta is one of the main reasons why NASA sent all-terrain vehicle about the size of a car to Jezero, and according to members of the mission, so far this place lives up to expectations.

Perseverance has collected four delta samples since early July. All four have been drilled into rocks, showing that this part of Mars could probably have supported terrestrial organisms in the past and even retain signs of such microbial life.

“The rocks we are examining in the delta have the highest concentration of organic matter that we have ever found on a mission,” scientist Ken Farley of the California Institute of Technology in Pasadena, USA, said at a press conference on Thursday. fifteen).

“And, of course, organic molecules are the building blocks of life. So it’s all very interesting, because we have rocks that were deposited in a habitable environment in a lake that carries organics, ”he added.

One feature of the delta that Perseverance has recently experimented with and studied, a 0.9-meter-wide rock that the team calls Wildcat Ridge, is particularly intriguing. According to team members, Wildcat is a fine-grained mudstone that likely formed at the bottom of ancient Lake Jezero.

Crater samples on Mars are rich in organic compounds

The Perseverance SHERLOC (Raman and Luminescence Scan for Organic and Chemical Habitable Environments) found that the rock is abundant in organic matter that is spatially associated with sulfur-bearing minerals called sulfates.

“This correlation suggests that as the lake evaporated, both sulfates and organic matter were deposited, stored and concentrated in this area,” SHERLOC scientist Sunanda Sharma of NASA’s Jet Propulsion Laboratory in Southern California, USA, said during the team.

“On Earth, sulfate deposits are known to retain organic matter and may contain signs of life called biosignatures. This makes these samples and this set of observations some of the most intriguing we have ever taken on a mission and adds to some of the excitement the team had as we approached the front of the delta.”

Biosignature in samples from Mars will be difficult to prove

However, Farley and Sharma emphasized that these Martian compounds cannot be considered biosignatures. Organic matter may be created and deposited by purely geological processes, and the data collected by Perseverance does not yet tell enough about the original scenario to make a connection.

Indeed, according to Farley, it would be very difficult for the mission team to make such a determination using only the rover’s observations, as the task is difficult and the burden of proof that a supposed discovery of alien life must meet is too high. This reality is embodied in the mission of Perseverance.

The samples are expected to arrive on Earth in 2033.

If all goes according to plan, the samples collected by Perseverance will be sent to Earth as early as 2033 as part of a joint NASA-European Space Agency (ESA) campaign.

Once the samples are on our planet, scientists around the world will be able to examine them with a variety of instruments, many larger and more complex than anything a rover can mount.

Perseverance has 43 sample tubes, 15 of which are already sealed. 12 contain drilled rock cores, one is an atmospheric sample (the result of a first Perseverance rock sampling attempt that did not go as planned), and two are “witness tubes”.

The mission team will use witness test tubes to determine what materials in Mars samples, if any, could be contaminating Earth. The sample return plan includes an ESA-provided Earth Return Orbiter (ERO) and a NASA-built lander, scheduled to launch in late 2027 and early 2028, respectively.

Perseverance will travel to the lander and place its samples, which will be launched from the surface of Mars, aboard a rocket carried by the lander. ERO will pick up the samples in orbit around Mars and bring them back to Earth.

The rover, which landed with the tiny Ingenuity helicopter for technology demonstrations in February 2021, should still be healthy enough in the late 2020s to do the job of bringing in samples, according to NASA officials.

The claim is based on the Curiosity rover, which has the same basic body plan and nuclear power system as Perseverance and is still in Gale Crater on the Red Planet more than a decade after it landed.

But if the attempt fails, NASA and ESA have a plan B. Perseverance takes two samples of each rock it collects, one for storage on board and one for storage in one or more “deposits” at the Jezero.

Thus, if Perseverance is unable to deliver the samples, the return probe will land near the sample warehouses and pick up the vials one by one using two helicopters.

These helicopters will be launched aboard the lander and will be very similar to Ingenuity, which is still going strong after 31 missions to Mars. However, the sample collection helicopters will need to be slightly larger than the Ingenuity as they will be equipped with wheels to help them roll into the sample tubes.

The Perseverance team has already chosen a possible location for the first sample depot, a nice flat part of the Jezero that could be a safe landing area.

On October 19, the team members will hold a “to go or not to go” meeting to determine if they are ready to start dropping sample tubes there, said NASA Planetary Science chief Lori Gleizes. If the decision to “go away” is made, Perseverance will store 10 to 11 sample tubes on site, an operation that will likely take about two months.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet



NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

My power is very low, so this might be the last photo I can upload. But don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will, but I’ll sign here soon. Thank you for staying with me.

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
