It wouldn’t have been surprising for SpaceX to get priority on the range schedule since it had already reserved the launch window with the Space Force for April 10. SpaceX subsequently delayed this particular Starlink launch for two days until it finally launched on Saturday evening, April 12. Another SpaceX Starlink mission launched Monday morning.
There are several puzzling things about what happened last week. When SpaceX missed its reservation on the range twice in two days, April 10 and 11, why didn’t ULA move back to the front of the line?
ULA, which is usually fairly transparent about its reasons for launch scrubs, didn’t disclose any technical problems with the rocket that would have prevented another launch attempt. ULA offers access to listen to the launch team’s audio channel during the countdown, and engineers were not discussing any significant technical issues.
The company’s official statement after the scrub said: “A new launch date will be announced when approved on the range.”
Also, why can’t ULA make another run at launching the Kuiper mission this week? The answer to that question is also a mystery, but we have some educated speculation.
Changes in attitudes
A few days ago, SpaceX postponed one of its own Starlink missions from Cape Canaveral without explanation, leaving the Florida spaceport with a rare week without any launches. SpaceX plans to resume launches from Florida early next week with the liftoff of a resupply mission to the International Space Station. The delayed Starlink mission will fly a few days later.
Meanwhile, the next launch attempt for ULA is unknown.
Tory Bruno, ULA’s president and CEO, wrote on X that questions about what is holding up the next Atlas V launch are best directed toward the Space Force. A spokesperson for ULA told Ars the company is still working with the range to determine the next launch date. “The rocket and payload are healthy,” she said. “We will announce the new launch date once confirmed.”
