NASA's new Astrophysics Cross-Observatory Science Support (ACROSS) initiative is organizing the 4th Time Domain and Multi-Messenger Astrophysics (TDAMM) Workshop.  This workshop will focus on developing community observing plans to enable the rapid and coordinated follow-up of explosive transients by space-based and ground-based observatories.

NASA invites U.S. and international members of the ground and space science communities to attend the workshop and contribute to its final product, a publicly available white paper with findings for relevant agencies and the broader astrophysics community. Learn more and register for the workshop.
