The goal of the Laboratory Analysis of Returned Samples (LARS) program is to maximize the science derived from planetary sample-return missions. Activities supported by LARS fall into two categories: (1) development of laboratory instrumentation and/or advanced techniques required for the analysis of returned samples; (2) direct analysis of samples already returned to Earth. Proposals may fall into either category or contain tasks that do both.

Amended April 9, 2020. The due dates for this program element have been delayed. Step-1 proposals are now due May 15, 2020, and Step-2 proposals are now due July 14, 2020.
