Mars 2020: Rover PLACES Bundle

March 22, 2022. Mars 2020 Release 3 includes the first release of the Rover PLACES bundle, covering all data acquired through February 18, 2022, 23:00 PST, or approximately sols 0-355..

The PLACES bundle has now completed its PDS peer review. In response to a reviewer's comment, a correction was made on March 23 to one of the Data Localization products, best_interp.csv. Users who downloaded this product before March 23 are advised to get the newest version of best_interp.csv and its label best_interp.csv.xml

The Mars 2020 Rover PLACES Bundle contains rover localizations and mechanism positions, along with ancillary data, extracted from the PLACES (Position Localization and Attitude Correction Estimate Storage) data base used in Perseverance rover operations.
