California will surpass its 10th rocket launch of the year less than two months into 2026. Here's how to livestream the next SpaceX Falcon 9 mission.
The helium system on the SLS upper stage —officially known as the Interim Cryogenic Propulsion Stage (ICPS)—performed well during both of the Artemis II countdown rehearsals. “ Last evening, the team was unable to get helium flow through the vehicle. This occurred during a routine operation to repressurize the system,” Isaacman wrote.
What: Falcon 9 rocket launch at Vandenberg Space Force Base in Santa Barbara County. When: Between midnight and 4 a.m. Saturday, according to SpaceX.
The Artemis 2 human lunar mission around the moon could be back on track after NASA pulled off a successful fueling test of the SLS rocket.
SpaceX halted Falcon 9 launches for a week while it investigated that issue, which was traced to a fuel leak in one of the booster's nine Merlin engines. This leak led to a fire shortly after touchdown, which weakened a landing leg and caused the vehicle to tip over.
The two-day countdown test at NASA’s Kennedy Space Center in Florida included filling up the tanks of the giant Space Launch System rocket with millions of pounds of liquid hydrogen and liquid oxygen.
