The first readings from the SuperCam instrument aboard NASA's Perseverance rover have arrived on Earth. SuperCam was developed jointly by the Los Alamos National Laboratory (LANL) in New Mexico and a consortium of French research laboratories under the auspices of the Centre National d'Etudes Spatiales (CNES). The instrument delivered data to the French Space Agency's operations center in Toulouse that includes the first audio of laser zaps on another planet.

"It is amazing to see SuperCam working so well on Mars," said Roger Wiens, the principal investigator for Perseverance's SuperCam instrument from Los Alamos National Laboratory in New Mexico. "When we first dreamed up this instrument eight years ago, we worried that we were being way too ambitious. Now it is up there working like a charm."

Perched atop the rover's mast, SuperCam's 12-pound (5.6-kilogram) sensor head can perform five types of analyses to study Mars' geology and help scientists choose which rocks the rover should sample in its search for signs of ancient microbial life. Since the rover's Feb. 18 touchdown, the mission has been performing health checks on all of its systems and subsystems. Early data from SuperCam tests - including sounds from the Red Planet - have been intriguing.

"The sounds acquired are remarkable quality," says Naomi Murdoch, a research scientist and lecturer at the ISAE-SUPAERO aerospace engineering school in Toulouse. "It's incredible to think that we're going to do science with the first sounds ever recorded on the surface of Mars!"

On March 9, the mission released three SuperCam audio files. Obtained only about 18 hours after landing, when the mast remained stowed on the rover deck, the first file captures the faint sounds of Martian wind.

The wind is more audible, especially around the 20-second mark, in the second sound file, recorded on the rover's fourth Martian day, or sol.

SuperCam's third file, from Sol 12, includes the zapping sounds of the laser impacting a rock target 30 times at a distance of about 10 feet (3.1 meters). Some zaps sound slightly louder than others, providing information on the physical structure of the targets, such as its relative hardness.

"I want to extend my sincere thanks and congratulations to our international partners at CNES and the SuperCam team for being a part of this momentous journey with us," said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington.

"SuperCam truly gives our rover eyes to see promising rock samples and ears to hear what it sounds like when the lasers strike them. This information will be essential when determining which samples to cache and ultimately return to Earth through our groundbreaking Mars Sample Return Campaign, which will be one of the most ambitious feats ever undertaken by humanity."

The SuperCam team also received excellent first datasets from the instrument's visible and infrared (VISIR) sensor as well as its Raman spectrometer. VISIR collects light reflected from the Sun to study the mineral content of rocks and sediments. This technique complements the Raman spectrometer, which uses a green laser beam to excite the chemical bonds in a sample to produce a signal depending on what elements are bonded together, in turn providing insights into a rock's mineral composition.

"This is the first time an instrument has used Raman spectroscopy anywhere other than on Earth!" said Olivier Beyssac, CNRS research director at the Institut de Mineralogie, de Physique des Materiaux et de Cosmochimie in Paris.

"Raman spectroscopy is going to play a crucial role in characterizing minerals to gain deeper insight into the geological conditions under which they formed and to detect potential organic and mineral molecules that might have been formed by living organisms."

Perseverance 'SuperCam' begins hunt for past life on Mars
Paris (AFP) March 10, 2021
The bundle of instruments known as SuperCam on board the Perseverance Mars rover has collected its first samples in the hunt for past life on the Red Planet, mission scientists said Wednesday. The return to Earth years from now of the rocks and soil it retrieves "will give scientists the Holy Grail of planetary exploration," Jean-Yves le Gall, president of France's National Centre for Space Studies (CNES), which mostly built the mobile observatory, commented via a YouTube broadcast. These "pie ... read more
