Interplanetary rivalry ignites as NASA taps relativity Space for 2028 Mars Orbiter mission

In a major expansion of its deep-space commercial outsourcing strategy, NASA has finalized a historic public-private partnership with Eric Schmidt’s Relativity Space to build and deploy an autonomous scientific orbiter to Mars. The announcement positions the unproven rocket startup as an immediate interplanetary challenger to Elon Musk's SpaceX, setting up a high-stakes corporate race to the Red Planet.
The mission, officially dubbed "Aeolus," is scheduled to blast off during the 2028 Martian launch window. Under the newly established framework, NASA will design and construct a specialized suite of weather and environmental instruments, while Relativity Space will absorb the operational risk of designing the spacecraft, managing the interplanetary transit, and launching the payload aboard its next-generation Terran R rocket.
A dual-purpose science station and orbital data center
The Aeolus orbiter is designed to deliver the scientific community’s first daily, global tracking network of the Martian atmosphere. Engineered by teams at NASA’s Ames Research Center, the four-instrument payload will actively map Martian wind profiles, atmospheric temperatures, localized pressure differentials, and shifting dust clouds up to 60 kilometers above the surface.
Beyond its meteorological duties, the spacecraft will debut a highly ambitious secondary infrastructure payload: an orbital "Relay Data Center." The proprietary system will embed server-class computing architecture and mass storage arrays directly into Mars orbit. Utilizing a hybrid network of advanced optical laser and traditional radio links, the spacecraft will run edge-AI processing models on board and serve as a high-bandwidth communication bridge for existing and future robotic rovers navigating the Martian terrain.
The Schmidt-Musk dynamic spills into deep space
The collaborative agreement represents a massive validation for Relativity Space, which underwent an aggressive corporate restructuring last year when former Google CEO Eric Schmidt acquired a controlling majority stake and installed himself as chief executive. Schmidt has quietly refocused the cash-strapped company's 3D-printing manufacturing lines toward establishing space-based cloud computing infrastructure, using a network of anonymous philanthropic backers to fund initial development flights.
The NASA selection injects a fascinating dynamic into the long-standing philosophical and technological rivalry between Schmidt and SpaceX founder Elon Musk, who have historically clashed over artificial intelligence safety and tech regulation.
Managing flight anomalies and development risk
Despite the immense hype surrounding the contract, aerospace analysts caution that the 2028 timeline leaves virtually zero margin for engineering delays. Relativity Space remains a highly speculative player in the heavy-lift launch sector; its smaller, early-stage Terran 1 vehicle suffered a second-stage structural failure during its lone flight attempt in March 2023. The company subsequently retired the platform to focus entirely on the massive, reusable Terran R, which is currently undergoing engine qualification testing ahead of an uncrewed maiden flight targeted for late 2026.
NASA leadership acknowledged the inherent volatility of backing a company that has yet to successfully achieve stable Earth orbit but emphasized that taking calculated risks is crucial to accelerating the pace of deep-space discovery. The agency is utilizing a six-year, reimbursable Space Act Agreement, ensuring public funding is directed solely toward instrument engineering and data pipeline processing while leaving the massive financial burden of launch logistics and rocket development entirely on the commercial sector.
