One year on Mars – the Perseverance rover

NASA’s Perseverance Mars rover snapped this view of a hill in Mars’ Jezero Crater called “Santa Cruz” on April 29, 2021, the 68th Martian day, or sol, of the mission. About 20 inches (50 centimeters) across on average, the boulders in the foreground are among the type of rocks the rover team has named “Ch’ał” (the Navajo term for “frog” and pronounced “chesh”).

The Perseverance rover has been on Mars for a year. What have learned about “Mars’ watery past” and how will this impact future exploration by rovers and humans.

On Thursday, February 17, 2022 the Jet Propulsions Laboratory held its annual von Kármán Lecture, this year titled, One Year on Mars.

The host was Brian White, Public Services Office, NASA/JPL and the co-host was Nikki Wyrick, Public Services Office, NASA/JPL.

The guests were;

  • Jennifer Trosper, Mars 2020 Project Manager, NASA/JPL
  • Dr. Katie Stack Morgan, Deputy Project Scientist, Mars 2020, NASA/JPL

Watch Perseverance Rover – Findings from One Year on Mars

Mars Perseverance Rover background

The Perseverance Mars rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life.

Perseverance is investigating Jezero Crater – a region of Mars where the ancient environment may have been favorable for microbial life – probing the Martian rocks for evidence of past life. The rover carries an entirely new subsystem to collect and prepare Martian rocks and sediment samples that includes a coring drill on its arm and a rack of sample titanium tubes in its chassis. Throughout its exploration of the region, the rover will collect promising samples, sealing them are tubes and storing them in its chassis until Perseverance deposits them on the Martian surface to be retrieved by a future mission. Perseverance will likely create multiple “depots” later in the mission for this purpose. increases the likelihood that especially valuable samples will be accessible for retrieval. Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and bring them to Earth for in-depth analysis using powerful laboratory equipment too large to take to Mars.

Two science instruments mounted on the rover’s robotic arm are used to search for signs of past life and determine where to collect samples by analyzing the chemical, mineral, physical, and organic characteristics of Martian rocks. On the rover’s mast, two science instruments provide high-resolution imaging and three types of spectroscopy for characterizing rocks and soil from a distance, also helping to determine which rock targets to explore up close.
