R5-S2, part of the same small satellite formation as R5-S4, contributing to coordinated multi-spacecraft technology testing.ibuting to coordinated multi-spacecraft technology testing that informs how future distributed sensing or communications missions might coordinate several small satellites acting as one system. Its French-Chinese pedigree, uncommon among astrophysics missions given ongoing geopolitical tension between the two nations' broader space programs, made the collaboration itself nearly as notable as the science.
