Relativity Space, a startup whose only rocket launch ended in failure, has been tapped by NASA to build and launch a critical Mars orbiter in 2028. This decision places a significant deep-space mission in the hands of a company yet to achieve orbital success, raising questions about the agency's evolving risk assessment and its commitment to mission reliability.
NASA has awarded a high-profile Mars mission, named Aeolus, to Relativity Space, but the company has never successfully put a payload into orbit. Its sole launch, the Terran 1 rocket, failed to reach orbit as planned, according to Startup Fortune. This selection of an unproven entity for a vital interplanetary mission marks a notable departure from NASA's traditional procurement methods.
NASA appears to be trading established reliability for the potential speed and innovation offered by a private startup, a strategy that could either revolutionize deep space missions or lead to costly failures. A profound shift in the agency's risk tolerance, prioritizing potential innovation over proven reliability for deep-space endeavors, a move that could jeopardize future deep-space endeavors, is indicated by this choice.
The Aeolus Mission and Relativity's Comprehensive Role
NASA selected Relativity Space to provide both the spacecraft and the rocket for the Aeolus probe mission to Mars, reports Scientific American. This integrated contract means Relativity Space is responsible for the entire mission architecture, from vehicle construction to launch. The company announced its intention to build and fly a science orbiter to Mars on June 17, 2026, according to Space Daily, suggesting a proactive push from the startup itself.
The Aeolus orbiter will carry NASA's atmospheric instruments, designed for scientific research into Mars' environment. Crucially, it will also serve as a communications relay for surface assets already on Mars or planned for future missions. This dual role significantly amplifies the risk associated with an unproven provider, as a failure could isolate existing or future Mars surface missions. Entrusting an unproven startup with this vital "communications relay for surface assets" means NASA is not just risking a single orbiter, but potentially isolating existing or future Mars surface missions, placing an unprecedented bet on a company that has yet to achieve orbit.
Relativity Space's Ambitious Trajectory
Relativity Space announced on June 17, 2026, that it would build and fly a science orbiter to Mars in 2028, as reported by Space Daily. This aggressive timeline for a company that has never successfully reached orbit suggests an extraordinary, perhaps pressured, push to accelerate Mars exploration. The private sector's influence appears significant in this trajectory.
Eric Schmidt, former Google CEO, took a majority stake in Relativity Space last year and installed himself as CEO, according to TechCrunch. His high-profile involvement suggests a substantial private sector push to validate Relativity Space through a major government contract. This leadership change and significant investment likely influenced NASA's risk assessment for this critical mission, positioning Relativity as an attractive, albeit risky, partner.
Why NASA Prioritizes New Commercial Partners
NASA's choice likely reflects a strategic shift towards fostering commercial space capabilities and potentially leveraging private sector agility to accelerate its ambitious exploration timelines. The agency may seek to reduce costs and encourage innovation by engaging newer companies in high-stakes projects. This approach could be an attempt to diversify its supplier base and avoid dependency on traditional, often more expensive, aerospace contractors.
However, a profound shift in the agency's risk tolerance is signaled by this decision. NASA is prioritizing potential innovation over proven reliability for deep-space endeavors. This strategy carries inherent technical and reliability risks, especially for a mission vital for communications relay, which could have cascading effects on other Mars operations.
The Road Ahead for Mars Exploration
This bold move by NASA could either pave the way for faster, more cost-effective deep space missions with private partners or underscore the critical need for established reliability in such high-stakes endeavors. The success or failure of the Aeolus mission will heavily influence future NASA procurement strategies and the role of commercial startups in deep-space exploration. A successful mission could validate NASA's new risk-taking approach, while a failure might force a re-evaluation of its commercial partnership models.
The aggressive 2028 timeline for a company that has never reached orbit to build both a Mars spacecraft and rocket suggests either an extraordinary, unstated confidence in Relativity's capabilities or a desperate push by NASA to accelerate Mars exploration, regardless of the inherent risks. The aerospace community will closely watch Relativity Space's progress as it prepares for its ambitious Mars launch within the next two years.
Addressing Key Questions
Which rocket company was selected for the 2026 Mars mission?
Relativity Space was selected by NASA to build and launch the Aeolus Mars orbiter. The company plans to use its Terran R rocket for the mission, a reusable launch vehicle currently under development. The Terran R is designed to carry larger payloads than its predecessor, Terran 1, which failed to reach orbit.
What is the goal of NASA's 2026 Mars mission?
The Aeolus mission aims to study the Martian atmosphere using specific instruments. It also serves a vital secondary role as a communications relay, supporting future surface missions and enhancing data transmission from existing Mars assets. This dual purpose makes the mission's success critical for broader Mars exploration efforts and the continuity of scientific data.
What technology will be used for the 2026 Mars mission?
Relativity Space will construct both the Aeolus spacecraft and its Terran R launch vehicle. The Terran R rocket utilizes 3D-printed components, a core innovation for Relativity Space, aiming to reduce manufacturing time and costs significantly. The Aeolus orbiter itself will house NASA's advanced atmospheric instruments, contributing to our understanding of Mars' climate and atmospheric processes.
