We are pleased to announce the initial release of the Astrophysics Cross-Observatory Science Support (ACROSS) web portal and the associated ACROSS software tools. The ACROSS initiative represents part of NASA’s response to the Astro2020 Decadal Survey’s identification of Time-Domain and Multimessenger Astrophysics (TDAMM) as a top priority for the 2020s. ACROSS addresses coordination challenges that impact the capability for rapid response to new astrophysical events across NASA’s fleet (and ground- and space-based observatories globally). ACROSS provides the infrastructure needed to implement a “whole-of-fleet” approach to TDAMM science, ensuring smaller missions like BurstCube achieve maximum impact alongside flagship observatories. The software tools are open source. We look forward to your feedback and collaboration!
