Cape Canaveral, FL (Florida Today) -- A helium leak forced SpaceX to scrub Monday's attempt to launch a Falcon 9 rocket and Dragon cargo capsule from Cape Canaveral Air Force Station.
No further details were immediately available.
SpaceX Launch Director Ricky Lim reported the scrub to his team a little more than an hour before the planned 4:58 p.m. liftoff.
"We have encountered an issue that will result in our scrubbing" the launch, Lim said in an announcement replayed on NASA TV. "The team here will start to safe the vehicle, offload propellants and then work on the details of the next few days forward."
SpaceX expects to be ready to try again at 3:25 p.m. Friday, the next available attempt due to orbital dynamics determing how quickly Dragon can reach the station with time-sensitive experiments.
There's a 40 percent chance of favorable weather on Friday.
