This new video details the rover’s Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals instrument – mercifully shortened to SHERLOC.

Suit material

Mars Guy points out that the Perseverance rover carried pieces of NASA space suit material to the surface of Mars for long-term exposure testing in the harsh environment. The first extremely high resolution images have now been sent back.

Also onboard is a piece of the Martian meteorite Sayh Al Uhamer 008 (SaU008) – a meteorite found in Oman in 1999. It is the first Mars sample return, Mars Guy explains, a piece of Mars that landed on Earth to be returned to Mars via the Perseverance rover.
