The American company that launched a mission to the Moon says there is "no chance" of a soft landing due to a fuel leak.
Pittsburgh-based Astrobotic, said there was enough propellant to operate its Peregrine lander as a spacecraft.
The lander is expected to run out of fuel in about 40 hours, the firm said shortly after 17:00 GMT on Tuesday.
The 1.2-tonne lander was launched from Cape Canaveral on Monday, with the intention of landing in late February.
"Given the propellant leak, there is, unfortunately, no chance of a soft landing on the Moon," the company said in a statement posted on X, formerly Twitter.
"The team has updated its estimates, and we currently expect to run out of propellant in about 40 hours from now - an improvement on last night's estimate.
"The team continues to work to find ways to extend Peregrine's operational life."
