Amendment 83: D.15 LISA Preparatory Science Mandatory NOIs Now Due January 20, 2023

The LISA Preparatory Science (LPS) program (D.15 of ROSES) solicits proposals from U.S. investigators to conduct activities that contribute to furthering the eventual science yield of the ESA-led Laser Interferometer Space Antenna (LISA) gravitational wave observatory planned for launch in the early 2030s. It is not intended as a vehicle for funding specific U.S. contributions to the LISA instrument or science ground segment, or to develop concepts for other missions outside of LISA.

ROSES-2022 Amendment 83 reopens the opportunity to submit a mandatory Notice of Intent (NOI) for this program. Mandatory NOIs must now be submitted by January 20, 2023. The proposal due date remains unchanged: March 16, 2023.

On or about January 12, 2023, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2022" (NNH22ZDA001N) will be posted on the NASA research opportunity homepage at
