European Space Agency Goes to NASA for Mars Rover Launch Using Pioneering Nuclear Power Source After Splitting with Russia

After splitting from Russia's Roscosmos due to geopolitical issues, the European Space Agency (ESA) and NASA collaborated to launch the ExoMars Rosalind Franklin rover mission, the first to use a nuclear power source.

Nuclear Power Source: A Game-Changer in Space Exploration

The European Space Agency is set to deploy a revolutionary nuclear-powered device in its next expedition to Mars, pushing the boundaries of space exploration. This new tech is the first to use Americium to warm the spacecraft components and will be integrated into the Rosalind Franklin rover, Europe's inaugural Mars rover.

The project was announced on May 16 and is backed by NASA in their new agreement, which heralds a new era in space investigation. Europe was initially in partnership with Roscosmos of Russia, but it was terminated in 2022 because of the invasion of Russia into Ukraine.

To warm spacecraft, radioisotope heater units (RHUs) use heat from the radioactive decay of materials, eliminating the requirement for energy produced by solar panels. Previously, depending on US or Russian plutonium-238 RHUs, the ESA created its program in 2009.

The new European RHUs will be the first to use americium-241, a more abundant and cheaper by-product of plutonium decay, despite having lower power per gram. These RHUs will heat the mission's landing platform, which deploys the rover onto the Martian surface. Extending the lander's operational life provides a backup if issues arise during rover deployment.

Orson Sutherland, head of ESA's Mars Exploration group, said the organization's americium RHUs are a significant accomplishment. The Rosalind Franklin rover, built to look for ancient life on Mars, has a 2-meter drill to probe underneath the surface.

The mission was initially scheduled to launch in 2018 but was delayed because of COVID-19 and technical difficulties. After Russia's cooperation, ESA had to rethink the program, build a new lander, and enlist NASA's help.

The Americium RHUs are under development as part of the European Devices Using Radioisotope Energy (ENDURE) project, and certification is needed before the anticipated debut in 2028. The National Nuclear Laboratory will produce the required americium pellets in the United Kingdom. To enable longer mission durations and the investigation of previously unreachable regions, ESA plans to develop americium batteries for future Moon missions by the 2030s.

NASA's Vital Role in Mission Success

NASA's critical participation in the ExoMars Rosalind Franklin rover mission cannot be understated, especially with the ESA leading the way. After ESA and Roscosmos parted ways, NASA stepped forward to offer vital assistance, which included finding a US commercial launch provider and sending vital heater units and rover propulsion system components.

The partnership between NASA and ESA exemplifies how international cooperation in the search for scientific knowledge can succeed. By combining their expertise and resources, these two elite space organizations want to accomplish ground-breaking outcomes in the exploration of Mars and the hunt for evidence of extinct life.

The Rosalind Franklin rover is equipped with its cutting-edge drill, wherein it can dig for up to 6.5 feet below the Martian surface, which could help solve long-standing mysteries of the planet's history and its possible habitability. This innovative project replaces the earlier Mars rovers, reflecting humanity's pursuit of knowledge in space and propelling humankind's cosmic journey.

As the launch date 2028 approaches, excitement is building for the culmination of years of careful planning and preparation. The success of the ExoMars Rosalind Franklin mission depends heavily on the efficient collaboration between NASA and ESA and the inventiveness of the scientists, engineers, and technicians working on the project.
