Rhea Space Activity raises $6M Series A for GPS-free spacecraft navigation software

Rhea Space Activity, a Washington, D.C. startup, raised $6 million in a Series A round to develop navigation software that can operate without GPS. The funding is intended to advance GPS-denied spacecraft positioning and guidance, shifting onboard navigation closer to software-defined resilience.

Artemis II Orion heat shield “aces” lunar reentry after Integrity splashdown NASA reports that the Orion “Integrity” heat shield performed “wonderfully” during Artemis II’s lunar return, meeting or exceeding expectations despite extreme reentry conditions (~2,800°C and ~40,000 km/h). Crew inspections shortly after splashdown found the shield in better-than-expected condition, supporting mission readiness for subsequent Artemis flights.

New manufacturing method makes realistic lunar-soil simulant for faster rover resilience testing A new manufacturing technology could make it easier to produce realistic lunar-soil materials for testing rover durability and mobility. By improving how closely ground tests replicate lunar regolith, the approach aims to shorten validation cycles for hardware intended to operate on the Moon’s surface.

NASA-led plan to test lunar material flammability—challenging Earth-based fire screening standard NASA Glenn and Johnson Space Center researchers, with Case Western Reserve University, are outlining a mission to test how materials burn on the Moon’s surface. The work targets limits of the long-used NASA-STD-6001B Earth-based flammability screening, where flame behavior may differ in lunar environments.
