Welcome to Edition 8.33 of the Rocket Report! NASA officials seem optimistic about launching the Artemis II mission next month, so confident that they will forgo another fueling test on the Space Launch System rocket to check the integrity of fickle seals in a liquid hydrogen loading line. The rocket will return to the launch pad next week, with liftoff targeted for April 1 at 6:24 pm EDT (22:24 UTC). NASA has six launch dates available in early April after the agency added April 2 to the launch period. April 1 and 2 each have launch windows that open before sunset, an added bonus for those of us who prefer a day launch, for purely aesthetic reasons.

Firefly’s Alpha rocket flies again. Firefly Aerospace’s Alpha rocket successfully returned to flight Wednesday, March 11, launching a technology demonstration mission more than 10 months after the rocket’s previous launch failed, Space News reports. The launch followed several delays and scrubbed launch attempts. The two-stage Alpha rocket lifted off from Vandenberg Space Force Base, California, and headed southwest over the Pacific Ocean, reaching orbit about eight minutes later. Firefly said the rocket’s upper stage later reignited its engine, demonstrating restart capability required for some orbit insertion missions. This was the seventh flight of Firefly’s Alpha rocket, capable of hauling more than a ton of payload to low-Earth orbit.
Block II preview... The recent setbacks for Firefly’s Alpha program included a launch failure last April and a fire that destroyed a booster stage on the test stand. The Texas-based company billed this week’s flight as a purely demonstration mission to validate several upgrades for the Alpha Block II rocket configuration, which will debut on the next launch. The Block II will include a 7-foot (2-meter) increase to Alpha’s length, consolidated batteries and avionics built in-house, improved thermal protection systems, and stronger carbon composite structures built with automated machinery. This week’s flight carried the rocket’s new in-house avionics suite and enhanced thermal protection system, Firefly said. “Flight 7 served as a critical opportunity to validate Alpha’s performance ahead of our Block II upgrade, and this team knocked it out of the park,” said Adam Oakes, Firefly’s vice president of launch.
