Amendment 21: E.10 Lunar Explorer Instrument for Space Biology Applications Final Text and Due Dates

E.10 Lunar Explorer Instrument for Space Biology Applications (LEIA) is intended to solicit ground-based proposals for an autonomous biological research experiment using yeast as a model organism to be integrated into the Biosensor hardware and tested for hardware biocompatibility. This is to establish a functional experimental payload that is flight ready. This opportunity is not meant to encompass the spaceflight, only to prepare the investigation for future flight opportunities.

ROSES-2021 Amendment 21 releases final text and due dates for E.10 LEIA which was previously released as draft for community comment. Mandatory NOIs are due June 7, 2021, and proposals are due July 16, 2021.

On or about May 17, 2021, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2021" (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at
