One rocket got off the ground Monday afternoon at Vandenberg Space Force Base while a different booster still stands awaiting its own chance for liftoff, spoiling plans for a double-header day.

Forced to scrub Monday morning’s liftoff attempt, the Firefly Aerospace team has backup opportunities through Thursday, with a dally opportunity from 6:37 to 7:29 a.m. at Space Launch Complex-2. 

As of Monday afternoon, officials confirmed the next attempt would take place Tuesday morning after apparently resolving the ground support equipment issue that kept the mission earthbound. .

“The rocket and spacecraft remain healthy and ready for launch,” Firefly said on social media. 

The decision to bypass a Monday departure occurred after the team tackled earlier issues that led to looking for a liftoff at the end of the launch window.

Alpha, making the program’s sixth flight since its debut, will deliver the Lockheed Martin Corp.’s LM 400 to demonstrate the firm’s new multi-mission satellite bus, or frame.

The LM 400 has been designed to host a variety of missions — including remote sensing, communications, imaging and radar — for military, commercial or civil customers.

The mission had aimed for Sunday morning, but unfavorable weather prompted the team to postpone the countdown.

Meanwhile, a SpaceX Falcon 9 rocket blasted off at 1:42 p.m. Monday from Space Launch Complex-4 after being delayed a day.

The Falcon 9 rocket deployed the 27 Starlink satellites into orbit approximately one hour after liftoff, SpaceX confirmed.

The first-stage booster, completing its 25th launch and landing, touched down on a droneship in the Pacific Ocean. 

Monday’s mission marked the fifth flight for Falcon 9 rockets during April for the SpaceX team at Vandenberg.
