The mission aims to launch in 2028, with Relativity funding and building the spacecraft with its own Terran R rocket powered to deliver NASA’s science payloads to orbit.
NASA has announced a new public-private partnership with Relativity Space aimed at advancing Mars exploration with a mission designed to deliver critical atmospheric data that will support future robotic and human landings on the Red Planet.
Under the agreement, NASA will provide the Aeolus atmospheric science instrument cluster, while Relativity Space will supply the spacecraft, launch vehicle and cruise operations needed to transport the payload to Mars. The mission is scheduled to launch in 2028 and represents a new approach for NASA to combine its scientific expertise with commercial innovation in order to accelerate research and increase mission opportunities.
NASA said the collaboration reflects its broader strategy to leverage commercial investment and development capabilities while focusing the agency’s resources on high-value science targets. Data collected by Aeolus is expected to improve understanding of the Martian atmosphere and help reduce risks associated with future manned and unmanned missions.
“Public-private partnerships like these are force multipliers for science,” said NASA Administrator Jared Isaacman. “By connecting NASA’s world-class tools with commercial innovation and investment, we can deliver more science, more often, and reduce the time it takes to get essential data into the hands of researchers preparing for future human missions to Mars.”
The Aeolus mission will carry a NASA-developed suite of four complementary instruments designed to provide the first global, integrated daily assessment of Martian winds, temperatures, dust activity and cloud formations. Scientists expect the mission to significantly improve atmospheric models by generating detailed information about seasonal weather patterns and environmental conditions across the planet.
The data will play a key role in improving entry, descent and landing techniques and improving mission planning for future astronauts. By providing a clearer understanding of the behavior of the atmosphere, the mission aims to make future Mars landings safer and more predictable.
Aeolus builds on more than 20 years of NASA-led Martian atmospheric research conducted by missions such as MAVEN, Mars Reconnaissance Orbiter, and Mars Odyssey. NASA said the new mission will expand the scientific foundation established by those programs while providing a more comprehensive view of the Martian atmosphere.
Researchers at NASA’s Ames Research Center in California’s Silicon Valley will design, build and integrate the payload, while Relativity Space will oversee spacecraft development and mission operations. NASA Ames Center Director Dr. Eugene Tu said the mission demonstrates how innovative partnerships can accelerate scientific discoveries and strengthen the technological foundations needed to eventually send humans to Mars.
The Aeolus payload assembly will include four instruments developed by NASA. The Doppler wind and temperature instrument, developed in collaboration with GATS, will measure wind and temperature characteristics from the surface of Mars to an altitude of about 60 kilometers. The Thermal Limb Sounder, created in partnership with Xiomas Technologies, will collect temperature data while monitoring clouds of dust and water ice. The surface radiative sensor package will measure the surface energy balance as well as dust and cloud properties, while a wide-area context camera will capture daily global images of atmospheric activity across the planet.
NASA will support science operations for at least one Martian year while Relativity Space maintains the spacecraft. The agency will also develop a custom data processing system to turn raw observations into scientific data products that can be widely used by researchers.
The mission will be carried out under NASA’s first six-year Reimbursable Space Act Agreement, providing a long-term framework intended to support stable development, mission continuity and continued cooperation between the agency and its commercial partner.
Through Aeolus, NASA aims to gain an unprecedented understanding of the Martian atmosphere while showcasing a new model of cooperation that could help accelerate future exploration of Mars and support the long-term goal of landing humans on the planet.
