A Bold Leap for Mars ScienceNASA has selected Relativity Space — the rocket company led by former Google CEO Eric Schmidt — to launch its ambitious Aeolus payload to Mars in 2028, marking a major milestone in public-private space exploration. The announcement signals a new chapter in how NASA approaches interplanetary science.
Under the deal, Relativity Space will provide the spacecraft, rocket, and cruise operations to carry Aeolus to the Red Planet. The payload itself is designed to study Mars' atmosphere in unprecedented detail, giving scientists the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds.
"This partnership combines NASA's scientific leadership with commercial innovation to advance Mars science," the agency said.## What Is the Aeolus Payload?Aeolus will carry four advanced instruments to study the Martian climate system. According to NASA, the data collected will:
- Directly inform entry, descent, and landing systems for future human and robotic missions
- Support safer, more predictable mission planning on the Martian surface
- Provide daily global weather maps of Mars for the first time
- Help scientists understand dust storm dynamics ## Relativity Space: From 3D Printing to Interplanetary TravelRelativity Space uses massive 3D printers to build most of its rocket components. The company's Terran R rocket is expected to be the workhorse for the Mars mission.
Why This Matters for Commercial SpaceThe partnership is structured as a public-private model where NASA provides scientific oversight and payload development, while Relativity handles launch and transit operations.
