Rocket Lab is challenging NASA's selection of a Mars communications orbiter contract to Blue Origin. The contract is worth up to $700 million. In 2021, Blue Origin fought NASA's choice of SpaceX for a crewed lunar lander. That dispute was over the lunar lander award.
Now Blue Origin has won the Mars orbiter contract. Rocket Lab is challenging the award. Rocket Lab's protest is the current dispute. This time, Blue Origin is the winning side and Rocket Lab stands as the challenger.
