'Critical' fuel leak puts the first US commercial moon landing mission in peril

It is a joint venture between Lockheed Martin and Boeing 

The Peregrine lunar lander, built by Astrobotic 

The Peregrine lunar lander, launched with the Vulcan rocket from the United Launch Alliance 

Astrobotic said the lunar lander was experiencing a "propulsion anomaly" that was preventing it from orienting the solar panels toward the sun 

It was discovered to be a fuel leak. 

"Unfortunately, it appears the failure within the propulsion system is causing a critical loss of propellant," Astrobotic said
