ABL Space Systems has pushed the debut liftoff of its RS1 rocket back a day to Tuesday (Jan. 10), citing high winds at its Alaska launch site.
The California-based startup tried to launch its RS1 rocket multiple times from the Pacific Spaceport Complex in Alaska in November 2022 but was thwarted on each occasion by technical issues. Another attempt on Dec. 8 was scrubbed six minutes before liftoff when the launch team noticed abnormal data readings from the rocket.
That latest issue likely has a "thermoelectrical or thermomechanical root cause," ABL representatives said via Twitter on Dec. 13. The company stood down to address it, delaying the next liftoff attempt to Jan. 9 at the earliest.
That try has now been pushed back by an additional day, to Tuesday (Jan. 10), due to high winds at the launch site, ABL said via Twitter on Monday (Jan. 9). ABL will attempt to launch at 6 p.m. EST (2300 GMT) on Tuesday, but the liftoff will apparently not be livestreamed; the company will provide updates on the mission via Twitter.
ABL Space Systems, which was founded in 2017, intends to snare a large share of the small-satellite launch market with the RS1.
The 88-foot-tall (27 meters) rocket can deliver up to 2,975 pounds (1,350 kilograms) to low Earth orbit on each flight, according to the company. ABL is currently selling missions aboard the rocket for $12 million apiece.
Though the coming mission is a test flight, the RS1 is carrying operational satellites: The rocket will try to deliver to orbit two cubesats called VariSat-1A and VariSat-1B. The shoebox-sized satellites will test marine data communications operations for the company VariSat LLC, if all goes according to plan.
Editor's note: This story was updated at 3:55 p.m. EST on Jan. 9 with news of the latest launch delay, to no earlier than Jan. 10.
