NASA’s Perseverance Mars rover begins hunt for signs of past life

NASA’s Perseverance Mars rover has begun its hunt for proof of historical microbial life. 

The spacecraft, which landed on the red planet in February, has examined an array of devices on its 7-foot robotic arm. 

In a Monday release, NASA stated that Perseverance had commenced its probe of Martian rocks and sediment, testing detectors and capturing its first science readings.



The rover will use X-rays and ultraviolet mild to look at rocks along with zooming for “closeups” of surfaces.

The company stated that Perseverance’s PIXL (Planetary Instrument for X-ray Lithochemistry) – an X-ray instrument – had already proven “unexpectedly strong science results” throughout its testing, together with figuring out the composition of Martian mud clinging to a small calibration goal aboard Perseverance

“We got our best-ever composition analysis of Martian dust before it even looked at rock,” Abigail Allwood, PIXL’s principal investigator at NASA’s Jet Propulsion Laboratory, stated.

Perseverance stays within the space round Jezero Crater – NASA’s preliminary touchdown website and a crater lake billions of years in the past.

Working with the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) spectrometer – which makes use of an ultraviolet laser to map mineralogy and natural compounds – and its WATSON (Wide Angle Topographic Sensor for Operations and Engineering) digicam, NASA scientists mixed mineral maps from the three devices. 

Early photographs from WATSON have already supplied information from Martian rocks, based on NASA, together with info concerning colours, sizes of grains and the presence of “cement” between the grains. 

Eventually, the Perseverance rover will gather and cache the rock and regolith to be returned in a joint mission with the ESA (European Space Agency).

However, any geological insights found earlier than then will likely be essential to understanding the historical past of the crater and “place any indication of possible life in context.”

“Mars 2020, in my view, is the best opportunity we will have in our lifetime to address that question,” stated Kenneth Williford, the deputy project scientist for Perseverance.
