Rocket Lab has rescheduled its launch of its Electron rocket for Thursday. The launch window opens at 0130 UMT (8:30 p.m. EST Wednesday). The previous attempt was aborted with two seconds left in the countdown due to an issue with the booster’s liquid oxygen (LOx).

“Launch was aborted due to rising liquid oxygen temperatures – the result of a LOx chilldown bleed schedule not compatible with the warm conditions of the day,” the company said in a tweet. “The fix is simple. Next attempt tomorrow!”

SpaceX has rescheduled the Falcon 9 launch of a Dragon resupply ship to the International Space Station for Friday at 1535 UMT (10:35 a.m. EST).

“Taking additional time for the team to conduct full inspections and cleanings due to detection of particles in 2nd stage fuel system,” SpaceX said in a tweet. “Now targeting CRS-13 launch from SLC-40 on Dec. 15. Next launch opportunity would be no earlier than late December.”
