  • The US's first lunar lander in decades is in trouble.
  • After launching on Monday, Peregrine Mission One started leaking fuel, Astrobotic said.
  • The situation is "critical" and may cost the lander its moon shot.

The first US-built lunar lander since the days of Apollo is leaking fuel and putting the entire mission at risk.

The leak is forcing the spacecraft's thrusters to operate beyond capacity to prevent the spacecraft from tumbling out of control.

Peregrine Mission One, a lunar lander built by Astrobotic, started leaking fuel hours after it launched from Cape Canaveral in Florida on Monday.
