Relativity Space to privately develop Mars orbiter mission

Relativity Space has announced its Interplanetary Sciences Program, a new initiative aimed at advancing planetary missions through private development. The program’s first mission is a Mars orbiter scheduled for launch in late 2028, focusing on science and telecommunications. The orbiter will include a suite of instruments contributed by NASA’s Ames Research Center, including an atmospheric profiling system and a radar for mapping subsurface ice and geology.

NASA confirmed the instrument suite, named Aeolus, includes a Doppler wind and temperature sensor, thermal limb sounder, surface radiometric sensors, and a wide-field camera. The agency will support the instrument’s operations for one Martian year and develop software to process the data. The mission aims to enhance scientific research and support future human missions to Mars by leveraging NASA’s expertise and commercial innovation.

The spacecraft will also function as a communications node, offering high-bandwidth laser and radio-frequency links to Earth and supporting communications with surface missions. It will feature significant data storage and computing capabilities, potentially enabling artificial intelligence and autonomous operations. While technical details remain undisclosed, the inclusion of a radar and advanced computing suggests substantial power requirements.

The mission will launch on Relativity’s Terran R reusable rocket, with funding reportedly coming from an undisclosed philanthropic organization. The company has not yet revealed details about future missions beyond the Mars orbiter, but the program is seen as a proof of concept for broader interplanetary exploration. Relativity’s focus on scalable and rapid launch capabilities aligns with its goal of making space more accessible for scientific and commercial purposes.
