WASHINGTON — NASA and the European Space Agency have completed an agreement under which NASA will provide hundreds of millions of dollars of support for a European Mars rover mission.
Officials with NASA and ESA signed the agreement May 16 at ESA's Paris headquarters, formalizing previously announced cooperation between the agencies on the ExoMars Rosalind Franklin rover mission, scheduled to launch in 2028.
The agreement confirms NASA's planned contributions to the mission, including throttable braking engines that will be used on a new descent stage being developed by ESA and radioisotope heating units (RHUs), which use heat from the decay of plutonium-238 to keep the spacecraft warm. The RHUs also require a launch from the United States on a vehicle NASA will procure.
