A spacecraft which was heading for the moon has suffered a "critical loss of propellant", the corporate behind it has stated.
It seems there was a "failure within the propulsion system", Astrobotic added.
It stated its group was attempting to stabilise Peregrine Mission 1, however "given the situation" it's prioritising "maximising the science and data" that may be captured.
It can be "alternative mission profiles".
Just half an hour earlier, Astrobotic stated communication had been re-established after a "blackout" when the battery ran very low.
Peregrine Mission 1's photo voltaic panels have been additionally pointing away from the solar.
Its group used an "improvised manoeuvre" which pointed Peregrine's "solar array" again in direction of the solar, it stated in a put up on X.
"We are now charging the battery," the corporate added.
Peregrine Mission 1 took off in Florida on a brand new Vulcan rocket at 7.18am UK time.
It is meant to be the primary US spacecraft to land on the moon's floor since Apollo 17 in 1972 and appeared to lift off into space as planned.
Astrobotic beforehand stated Peregrine "successfully" separated from the rocket however an "anomaly" had occurred.
The propulsion downside threatened the "ability of the spacecraft to soft land on the moon", it admitted.
A touchdown had been scheduled for 23 February.

NASA has paid Astrobotic, an area logistics start-up, $108m (£85m) for 5 scientific devices to be carried to the moon - a fraction of the price of launching its personal mission.
The lander, which is the dimensions of a backyard shed, can be carrying the stays of a number of Star Trek forged members and the DNA of former US presidents together with John F Kennedy.
Astrobotic chief govt John Thornton has beforehand stated the craft will spend 12 days in transit between the Earth and lunar orbit however the bulk of the time might be ready, circling the moon for the "local lighting conditions" of the group's touchdown web site to be appropriate.
In its first replace on the problem on X, Astrobotic stated on Monday that after efficiently separating from United Launch Alliance's Vulcan rocket, the Peregrine lander started receiving telemetry through NASA.
"After successful propulsion systems activation, Peregrine entered a safe operational state," it went on.
"Unfortunately, an anomaly then occurred, which prevented Astrobotic from achieving a stable sun-pointing orientation."

This had appeared like a dream begin to the Peregrine Mission.
But its future now hangs within the stability.
Astrobotic says the spacecraft is not in a "stable sun-pointing orientation".
That suggests its photo voltaic panels will not be harvesting wherever close to sufficient photo voltaic vitality and if the corporate cannot shortly stabilise the lunar lander it's going to lose energy.
It's unclear what has gone mistaken.
Everything gave the impression to be working completely. When mission controllers wakened the spacecraft, after it was launched from the launch rocket, every little thing carried out as anticipated.
It's attainable that there's a downside with the sensors the spacecraft makes use of to orientate its place utilizing the solar and stars. Or maybe there's a software program glitch.
Astrobotic might be attempting to work an answer. If it is {hardware}, can they use a back-up system? If it is software program, can they add new pc code to appropriate the bug?
They'll be doing every little thing they'll to avoid wasting the mission.
Part of the rationale for the renewal of curiosity in lunar missions is the invention of water on the moon, which might hydrate astronauts and be a supply of oxygen and gas - saving future missions from having to retailer their very own provides.
It is hoped the moon might present a staging put up for missions to Mars and even past.
Controversy over human stays
The Peregrine mission has attracted controversy due to a few of its industrial payloads.
Among the stays on board are these of Star Trek creator Gene Roddenbury - alongside along with his spouse and son - in addition to icons from the present Nichelle Nichols, James Doohan and DeForest Kelley, who performed Nyota Uhura, Montgomery Scott and Dr Leonard McCoy.
The DNA of former US presidents George Washington, Dwight Eisenhower and John F Kennedy are additionally being transported.
The Navajo Nation of Native Americans had written to NASA demanding the launch must be delayed as a result of there might be capsules on board containing human stays.
The nation's president, Buu Nygren, stated sending cremated stays to the moon "is tantamount to the desecration of this sacred space".
Eyebrows have additionally been raised over different industrial payloads.
The supply firm DHL is launching its MoonBox programme, taking mementoes reminiscent of images, novels and even a pattern of Mount Everest to the lunar floor.
Astrobotic has shrugged off criticism of the mission's industrial cargo.
"To be leading America back to the surface of the moon is a momentous honour," stated Mr Thornton.
