NASA has selected Relativity Space to develop a Mars mission called Aeolus, marking a notable step for a company that is still building its place in the launch market. The mission will carry a set of scientific instruments into orbit around Mars and is planned for launch in 2028.
The spacecraft will be designed to study the planet's atmosphere with four instruments that can map dust, winds, and temperature on a global scale. NASA says the data could help improve future landings and support long-term planning for human exploration of Mars.
The project follows a model NASA has used with other commercial partners: the agency defines the science goals, while the private company develops the space hardware and launch system. This approach is meant to combine public research priorities with private-sector speed and flexibility.
Relativity Space was founded in 2015 by former SpaceX and Blue Origin engineers and became known for its focus on 3D-printed rocket manufacturing. After its Terran-1 rocket flew in 2023, the company shifted attention to the larger Terran R vehicle. Eric Schmidt later took a majority stake in the company and became its CEO, giving the firm fresh momentum as it pursues ambitious space projects.
If Aeolus reaches Mars on schedule, it could become a landmark example of how commercial launch companies and scientific institutions can work together on deep-space exploration. The mission may also help shape the next era of orbital research and planetary access.
