Key facts
- NASA has contracted Relativity Space to build and launch a spacecraft to Mars by 2028.
NASA has contracted Relativity Space, led by former Google executive Eric Schmidt, to build and launch a spacecraft to Mars by 2028. The mission, dubbed Aeolus, aims to provide daily atmospheric imaging of the Red Planet, potentially positioning Relativity ahead of SpaceX in the race for Martian exploration.

This contract signifies a significant step for Relativity Space and Eric Schmidt, potentially validating their 3D-printed rocket technology and placing them in direct competition with SpaceX for lunar and Martian exploration contracts. It also highlights NASA's strategy of leveraging commercial innovation for ambitious space missions.
NASA has awarded a contract to Relativity Space, a rocket company acquired by former Google executive chair Eric Schmidt, to build and launch a spacecraft to Mars by 2028. The mission, named Aeolus, will carry scientific instruments designed to provide daily, global views of Mars' atmosphere, including dust, winds, and temperature. This data is expected to enhance safety for future landers and astronauts on the Red Planet.
The contract follows a model of public-private partnerships, where NASA handles the scientific payload while private companies provide infrastructure. This approach allows NASA to fund ambitious missions more cost-effectively. However, the partnership also carries risks, as Relativity Space is still an unproven entity, having experienced a launch failure with its Terran-1 rocket.
Relativity Space, founded by former SpaceX and Blue Origin engineers, aims to utilize 3D printing for cheaper rocket construction. The company is developing the larger Terran R rocket. Schmidt's investment and leadership came after the company faced fundraising challenges. His involvement has also been linked to potential projects like launching a space telescope financed by his family philanthropy.
The mission's 2028 target date presents a tight timeline for Relativity to design and build both the spacecraft and its rocket. If successful, the Aeolus mission could position Relativity Space ahead of competitors like SpaceX, which also has long-term Mars ambitions but has not yet sent its own dedicated mission to the planet.
