Deep Space Atomic Clock Moves Toward Increased Spacecraft Autonomy

Designed to improve navigation for robotic explorers and the operation of GPS satellites, the technology demonstration reports a significant milestone. Spacecraft that venture beyond our Moon rely on communication with ground stations on Earth to figure out where they are and where they’re going. NASA’s Deep Space Atomic Clock is working toward giving those far-flung explorers more…

NASA Helps Study One of the World’s Most Diverse Ecosystems

An international team of researchers spent October and November 2023 in the field studying one of the world’s most biologically diverse areas – South Africa’s Greater Cape Floristic Region. As part of the effort, researchers used NASA airborne and space-based instruments to gather complementary data to better understand the unique aquatic and terrestrial ecosystems in this region. Their…
