NASA OIG: Audit of the Mars 2020 Rover Project

"The largest risk to the Mars 2020 schedule is the Project's Sample and Caching Subsystem (Sampling System), which will collect core samples of Martian rocks and soil and place them on the planet's surface for retrieval by a future robotic or human mission. At Preliminary Design Review (PDR), three of the Sampling System's critical technologies were below technology readiness level (TRL) 6, meaning the prototype had not yet demonstrated the capability to perform all the functions required. Projects are evaluated during PDR to ensure they meet all system requirements with acceptable risk and within cost and schedule constraints. The immaturity of the critical technologies related to the Sampling System is concerning because, according to Mars 2020 Project managers, the Sampling System is the rover's most complex new development component with delays likely to eat into the Project's schedule reserve and, in the worst case scenario, could delay launch. As of December 2016, the Project was tracking the risk that the Sampling System may not be ready for integration and testing - the period when a spacecraft is built, undergoes final testing, and is prepared for launch - in May 2019, as planned."
