NASA time-domain and multimessenger astronomy technology investments

The Decadal Survey on Astronomy and Astrophysics 2020 issued in 2021 by the National Academies delivered strong recommendations for NASA to consider future missions to complement detections of gravitational waves and neutrinos with electromagnetic observations in space, and more generally to sustain its fleet of missions that contribute to the science enabled by multi-messenger and time-domain astronomy. In this presentation we discuss the current technology investments by NASA in this vibrant field, including detector development, infrastructure, suborbital experiments, and small satellites.
