Rocket Lab is protesting 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 selection of SpaceX for a crewed lunar lander. That challenge was connected to the lunar lander award.
Now Blue Origin has won the Mars orbiter award. Rocket Lab is disputing the selection. Rocket Lab's challenge is the latest dispute. This time, Blue Origin has won the award and Rocket Lab stands as the challenger.
