PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

This illustration depicts the interior of a sample tube being carried aboard the Mars 2020 Perseverance rover.

About the size and shape of a standard lab test tube, the 43 sample tubes headed to Mars must be lightweight, hardy enough to survive the demands of the round trip, and so clean that future scientists will be confident that what they are analyzing is 100% Mars, without Earthly contaminants.

Cutaway

  • Plunger: Works in concert with the spring to release (retract) or activate (extend) the two exterior-mounted ball locks.
  • Springs: Along with the plunger, acts to release or activate the ball locks.
  • Payload Cavity: Also known as the bore, is the area in the tube where cores of Martian rock and samples of regolith will be stored.
  • Titanium Nitride Coating: The specialized surface treatment resists contamination.
  • Hermetic Seal: This mechanically-activated plug is designed to ensure that no contaminants can get into the sample tube and that nothing from inside the tube can get out.

JPL built and will manage operations of the Mars 2020 Perseverance rover for NASA.
