Overview
- A formal public‑private Space Act Agreement announced Wednesday has NASA providing the four‑instrument Aeolus payload while Relativity Space supplies the spacecraft, Terran R launch vehicle and cruise operations for a planned 2028 launch.
- Aeolus is designed to deliver the first integrated daily, global maps of Martian winds, temperatures, dust and clouds to improve atmospheric models used for landings and future crewed missions.
- Under the deal NASA will operate the science instruments for at least one Martian year and build the data pipeline to turn raw measurements into ready‑to‑use science products, with the agency reimbursing Relativity under a six‑year framework.
- The mission faces near‑term risk because Terran R has not yet flown, Relativity’s interplanetary program is newly formed under Eric Schmidt’s leadership, and the company is relying in part on an undisclosed philanthropic funder.
- The partnership follows NASA’s broader strategy of buying services from commercial providers to increase mission cadence and could also expand Mars telecom, subsurface radar mapping and onboard high‑capacity data processing capabilities.
