Moon lander contracts
"Common Sense Sceptic has done a series on the moon lander contract that was awarded to SpaceX. There were supposed to be two finalists, but through some suspect dealings, SpaceX was the sole awardee and NASA didn't have the funds to properly fund that due to an insufficient appropriation from Congress. It's worth a view as it makes it plain how NASA gets whipsawed with changes in the political wind."
The amount of money initially allocated was too low for two fully formed bids but there was a widely held expectation that an old space firm would win it and continue to drain future budgets under the normal cost+ contract.
What wasn't anticipated was that SpaceX would come in with a significantly cheaper bid based on Starship so they got the contract.
Then the shenanigans started by Congress to get more money so that a second contract was awarded.
