Tricorder Tech: A.I. / Machine Learning: Adaptive Sampling With PIXL On Mars Perseverance

by Keith CowingMay 24, 2024May 24, 2024

Editor’s note: From the paper’s Introduction: “At the time of this writing, PIXL’s adaptive sampling capability has been operating on Mars for over 951 sols (martian days), with over 52 […]

A synthesis of the daily surface pressure measurements coverage (vertical axis LMST, Local Mean Solar Time) as a function of the sol number and solar longitude of Perseverance rover on Mars. The pressure is given in Pascal (Pa). Data are available in Rodríguez-Manfredi et al. (2021b). -- astro-ph.EP

Mars 2020 Perseverance Rover Studies Of The Martian Atmosphere Over Jezero From Pressure Measurements

by Keith CowingJanuary 25, 2024January 24, 2024

The pressure sensors on Mars rover Perseverance measure the pressure field in the Jezero crater on regular hourly basis starting in sol 15 after landing.

The bit carousel, which lies at the heart of Sample Caching System of NASA's Mars 2020 mission, is attached to the front end of the rover in the Spacecraft Assembly Facility's High Bay 1 at the Jet Propulsion Laboratory in Pasadena, California. The carousel contains all of the tools the coring drill uses to sample the Martian surface and is the gateway for the samples to move into the rover for assessment and processing. Credits: NASA
