Editor's Note: This advisory was updated Tuesday, Sept. 13, 2022, to note that Rick Welch, Perseverance deputy project manager, is now participating in the briefing in place of Art Thompson, Perseverance project manager.

Members of the mission will discuss the rover’s activities as it gathers samples in an ancient river delta.

NASA will host a briefing at 11:30 a.m. EDT (8:30 a.m. PDT) on Thursday, Sept. 15, at the agency’s Jet Propulsion Laboratory in Southern California to provide highlights from the first year and a half of the Perseverance rover’s exploration of Mars.

The rover landed in Mars' Jezero Crater in February 2021 and is collecting samples of rock and other materials from the Martian surface. NASA’s Perseverance is investigating the sediment-rich ancient river delta in the Red Planet’s Jezero Crater.

The briefing will livestream on NASA Television, Twitter, Facebook, and YouTube, as well as the agency’s app.

Watch on the agency's website at:

Participants will include:

  • Lori Glaze, director of NASA's Planetary Science Division, NASA Headquarters
  • Laurie Leshin, JPL director
  • Rick Welch, Perseverance deputy project manager, JPL
  • Ken Farley, Perseverance project scientist, Caltech
  • Sunanda Sharma, Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals scientist, JPL
  • David Shuster, Perseverance returned sample scientist, University of California, Berkeley

Questions can be asked on social media during the briefing using #AskNASA.

Perseverance marks the first step in the Mars Sample Return campaign, which would return scientifically promising samples to Earth for further study using the most sophisticated instruments around the world. These samples collected by Perseverance during its exploration of an ancient river delta are thought to be the best opportunity to reveal the early evolution of Mars, including the potential for life.
