NASA ran into a leak portion fueling its caller satellite rocket Monday (February 2, 2026) successful 1 last make-or-break trial that volition find erstwhile astronauts tin motorboat connected a lunar fly-around.
The motorboat squad began loading the 98-meter rocket with super-cold hydrogen and oxygen astatine Kennedy Space Centre astatine midday. More than 2.6 cardinal litres had to travel into the tanks and stay connected committee for respective hours, mimicking the last stages of an existent countdown.
But conscionable a mates hours into the daylong operation, excessive hydrogen was detected adjacent the bottommost of the rocket. Hydrogen loading was temporarily halted, with conscionable fractional of the halfway signifier filled.
The motorboat squad scrambled to enactment astir the occupation utilizing techniques developed during the lone different Space Launch System rocket motorboat 3 years ago. That archetypal trial formation was plagued by hydrogen leaks earlier yet soaring.
The crew, 3 Americans and 1 Canadian, monitored the captious formal rehearsal from astir 1,600 km distant successful Houston, location to Johnson Space Centre. They person been successful quarantine for the past one-and-a-half week, awaiting the signifier countdown's outcome.
The all-day cognition volition find erstwhile they tin blast disconnected connected the archetypal lunar voyage by a unit successful much than fractional a century.
Running 2 days down due to the fact that of a bitter acold snap, NASA acceptable its countdown clocks to halt a half-minute earlier reaching zero, conscionable earlier motor ignition. The clocks began ticking Saturday (January 31, 2026) night, giving motorboat controllers the accidental to spell done each the motions and woody with immoderate lingering rocket problems. Hydrogen leaks kept the archetypal SLS rocket connected the pad for months successful 2022.
If the fuelling demo tin beryllium completed successfully connected time, NASA could motorboat commandant Reid Wiseman and his unit to the satellite arsenic soon arsenic Sunday (February 8, 2026). The rocket indispensable beryllium flying by February 11 oregon the ngo volition beryllium called disconnected until March. The abstraction bureau lone has a fewer days successful immoderate fixed period to motorboat the rocket, and the utmost acold already has shortened February's motorboat model by 2 days.
The astir 10-day ngo volition nonstop the astronauts past the moon, astir the mysterious acold broadside and past consecutive backmost to Earth, with the extremity of investigating the capsule's beingness enactment and different captious systems. The unit volition not spell into lunar orbit oregon effort to land.
NASA past sent astronauts to the satellite during the 1960s and 1970s Apollo program. The caller Artemis programme aims for a much sustained lunar presence, with Wiseman's unit mounting the signifier for aboriginal satellite landings by different astronauts.
