NASA Selects Relativity Space for a Landmark 2028 Mission to Mars
In a major development for both commercial spaceflight and planetary science, NASA has officially selected Relativity Space — the rocket company led by former Google executive Eric Schmidt — to launch its Aeolus payload to Mars in 2028. The announcement marks a significant step forward in NASA's growing embrace of public-private partnerships to carry out deep-space science missions, and it signals that commercial launch providers are increasingly competitive players in the most ambitious corners of space exploration.
What Is the Aeolus Mars Mission?
The Aeolus mission is named after the keeper of the winds in Greek mythology, and the name is fitting. The primary scientific goal of the Aeolus payload is to deliver what NASA describes as "the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds." In other words, it will give scientists and mission planners an unprecedented, continuous picture of Mars's dynamic and often violent atmosphere.
The payload will carry four specialized instruments designed to study the Martian atmosphere in a level of detail that has never been achieved before. This atmospheric data isn't just scientifically interesting — it has direct, practical consequences for future Mars missions. According to NASA, the data gathered by Aeolus will "directly inform entry, descent, and landing systems and support safer, more predictable missions" to the Red Planet. As humanity sets its sights on eventual crewed Mars missions, understanding the atmosphere becomes one of the most critical engineering challenges to solve.
Relativity Space's Role in the Mission
Under the terms of the new public-private partnership, Relativity Space will be responsible for far more than just putting the payload on a rocket. The company will provide the spacecraft, rocket, and cruise operations needed to fly the Aeolus payload all the way to Mars. This end-to-end responsibility is a significant expansion of the role typically assigned to commercial launch providers, who are more commonly contracted simply to deliver a payload into Earth orbit.
Taking on cruise operations — the months-long journey through deep space between Earth and Mars — represents a major technical and logistical undertaking. It places Relativity Space alongside a very short list of companies capable of supporting interplanetary missions, a domain historically dominated by NASA's own Jet Propulsion Laboratory and a handful of established aerospace contractors.
Who Is Eric Schmidt, and Why Does It Matter?
Eric Schmidt served as CEO and later Executive Chairman of Google, helping to transform it into one of the most valuable technology companies in history. His involvement in Relativity Space as CEO brings both significant credibility and substantial resources to the company at a pivotal moment in its development. Schmidt has become an increasingly prominent figure in the intersection of technology, defense, and space, and his leadership of a company now entrusted with a NASA interplanetary mission underscores how dramatically the commercial space landscape has shifted over the past decade.
Relativity Space was originally founded in 2015 by Tim Ellis and Jordan Noone with the ambitious goal of 3D-printing entire rockets. The company developed a reputation for its innovative manufacturing approach and has been working toward orbital launches with its Terran R rocket. Securing a NASA Mars contract is a significant validation of the company's capabilities and long-term vision.
The Growing Role of Public-Private Partnerships in Space Exploration
NASA's decision to partner with Relativity Space for the Aeolus mission is part of a broader strategic shift at the agency. Over the past decade, NASA has leaned more heavily on commercial partners — from SpaceX's Falcon 9 and Crew Dragon vehicles to Rocket Lab's small satellite launches — to reduce costs and accelerate mission timelines. The Commercial Crew and Commercial Cargo programs set a powerful precedent for how public-private collaboration could make NASA's goals more achievable in an era of constrained budgets.
Extending this model to Mars science missions is a logical next step, but it is also a more complex one. Mars missions involve significantly higher risks, longer timelines, and greater technical demands than Earth-orbit operations. The fact that NASA is willing to trust a commercial partner with an end-to-end interplanetary mission speaks volumes about how far the commercial space sector has come.
Why Mars Weather Data Is Critical for the Future of Space Exploration
Understanding Martian weather is not merely an academic exercise. Mars has some of the most extreme and unpredictable atmospheric conditions in the solar system, including planet-wide dust storms that can last for months and wind patterns that pose serious risks to landing spacecraft. Every Mars lander and rover that has attempted entry, descent, and landing has done so with incomplete atmospheric data, making what engineers sometimes call "the seven minutes of terror" even more uncertain.
The Aeolus payload aims to close that knowledge gap. With daily, global atmospheric readings, future mission planners will be able to select landing windows with far greater confidence, design entry systems optimized for real Martian conditions, and potentially save billions of dollars in mission risk mitigation. For the long-term goal of landing humans on Mars, this data could prove essential.
Looking Ahead to 2028 and Beyond
With the 2028 launch window now confirmed and Relativity Space locked in as the mission partner, attention will turn to the technical milestones that must be achieved in the coming years. Relativity Space will need to demonstrate reliable launch capabilities, refine its spacecraft systems, and prove it can manage the complex cruise operations required for a Mars transit.
If successful, the Aeolus mission will not only deliver transformative science but also establish a new benchmark for what commercial aerospace companies can accomplish. It could open the door to further NASA contracts for interplanetary missions and help build the commercial infrastructure that a sustained human presence on Mars will eventually require. For now, all eyes are on Relativity Space and the bold bet NASA has placed on a new generation of space pioneers.
