The 33 Sample Tubes Collected by Perseverance

Shown here is an annotated composite image of the interiors of the 33 tubes NASA's Perseverance Mars rover has used to collect samples as of July 24, 2025, the 1,574th Martian day (or sol) of the mission. At this point, Perseverance has collected 27 rock cores, two samples of regolith (broken Mars rock and dust), and one atmospheric sample. The composite also includes images of the three witness tube interiors. Atop each image in white text is the name given to the sample by the rover science team. Ten of the samples depicted here – including one atmospheric sample and one witness tube – were deposited in January 2023 at the rover's sample depot at a location dubbed "Three Forks" within Jezero Crater. The other 23 samples collected thus far remain aboard the rover. Visit this page for details on each sample. The images of the sample tube interiors were collected by the rover's Sampling and Caching System Camera (known as CacheCam). https://photojournal.jpl.nasa.gov/catalog/PIA26643
