NASA is betting on the private sector to reach Mars

The US Space Agency (NASA) recently expanded the scope of its partnerships with the public and private sectors to include exploration of the planet Mars, after it concluded an agreement with the company “Relativity Space” to launch an orbital probe called “Aeolus”, provided that the launch does not take place before 2028.

The probe bears the name “Iolos,” which means “god of the winds” in Greek mythology, a name that is in line with the scientific mission it will perform, as NASA will provide the vehicle with four advanced scientific instruments that will provide, for the first time, a daily, comprehensive, planet-wide picture of the movement of winds, temperatures, dust storms, and clouds in the Martian atmosphere.

It is expected that the data that the probe will collect about weather and climate on the Red Planet will contribute to enhancing the readiness of future human missions to Mars, by providing more accurate information about the environmental conditions that astronauts will face.

The Aeolus mission is not limited to studying the atmosphere, but also includes exploring the ice layers near the surface and analyzing the rocky structure beneath the surface of Mars.

Within the framework of the agreement, Relativity Space will provide the probe and launch vehicle, and will also work to attract additional contributions from commercial companies, academic institutions, and non-profit organizations to develop other scientific payloads.

Missile development

Relativity Space was founded in 2015, with the aim of developing reusable rockets. It began its activity by producing small rockets, before moving on to developing medium and heavy rockets to compete with major companies such as SpaceX, Blue Origin, and Rocket Lab in the space launch market.

The first missile developed by the company was “Tiran-1”, which was launched in March 2023, and was able to reach space, but it did not succeed in reaching its target orbit after the third stage of the launch process suffered a technical defect.

Following that experience, the company decided to stop developing the “Tiran-1” and focus on developing the larger missile, the “Tiran-R”, which has a carrying capacity of about 23.5 tons to low Earth orbit.

The first launch of this missile is scheduled to take place later this year, and the company expects it to be the means of launching the “Aeolus” probe.

“Aeolus” represents the first mission within the planetary science program launched by “Relativity Space”, which aims to implement special scientific missions to explore the depths of the solar system, within a vision based on achieving “more scientific research for every dollar spent.”

techniques

The company seeks to develop and launch basic scientific technologies and payloads that serve scientific research priorities in the field of space exploration.

The company is currently led by former Google CEO Eric Schmidt, who assumed the position of CEO in March 2025, after acquiring a majority stake in it, and reports indicate that he provides a large portion of the financing necessary to expand its activities.

Schmidt has previously supported, with his own funds, a number of astronomical projects, including a space telescope called “Lazuli,” which was designed to be a new generation successor to the Hubble Space Telescope.

Continuous approach

In fact, relying on partnerships between the public and private sectors in the field of space exploration is not a new trend, as the administration of former US President George W. Bush began implementing this model after the Columbia space shuttle disaster, when it moved to privatize the operations of transporting goods, and then transporting astronauts, to and from the International Space Station. The administration of President Barack Obama continued to adopt this approach, and even expanded its scope significantly, after canceling the “Constellation” program dedicated to deep space exploration, which the Bush administration had launched.

During the first term of President Donald Trump, the policy of partnership with the private sector witnessed a new impetus through the revival of the “Artemis” program, which aims to return humans to the moon in preparation for heading towards Mars.

Real test

Within the framework of this program, the human landing system on the moon is being developed by SpaceX and Blue Origin, in preparation for returning astronauts to the moon’s surface for the first time in decades.

The commercial lunar payload services program has also achieved mixed results, with only the Blue Ghost unmanned lander developed by Firefly Aerospace having achieved complete success so far.

Despite this, NASA is still adopting this program as one of the basic components of the plan to establish a permanent base on the moon.

NASA’s partnership with Relativity Space constitutes a real test to see the extent to which some planetary science missions can be implemented based on the same partnership model that has proven successful in other space programs. If the Aeolus mission is successful, it will likely be followed by similar missions carried out by other private companies.

The mission gains additional importance in light of the current Trump administration’s tendency to give priority to the “Artemis” program, coinciding with proposals to reduce spending on planetary science and Earth science programs, which has raised widespread concerns within the scientific community about the future of robotic missions, compared to human exploration programs.

New model

The Aeolus mission represents an attempt to find a new model that achieves the greatest possible scientific return in light of limited financial resources, by expanding the private sector’s contribution to the implementation of scientific missions. However, the partnership with “Relativity Space” involves a degree of adventure, given that the “Tiran-R” missile has not yet carried out its first flight. However, the success of the missile and its entry into service will result in two important developments. The first is the inauguration of a new phase that can be described as the era of commercial planetary science, a phase that may not witness implementation. Giant space missions, but they will open the door to a large number of smaller and less expensive scientific missions.

The second development is that the success of “Tiran-R” will give “Relativity Space” a great opportunity to obtain new launch contracts, allowing it to join “Blue Origin” and “Rocket Lab” in competing with “SpaceX”, which continues to impose its dominance in the global space launch market.
