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