Good morning from Mojave, where our team is preparing for an end-to-end, capstone launch rehearsal of LauncherOne — the final test of our development program.
We’ve been pushing hard to prepare for this moment — rehearsing fueling operations, testing our telemetry hand-offs, simulating full-team missions, and all the other kind of work that needs to be done before debuting a new rocket.
Check out our blog to get up to speed on all of the activities leading up to this milestone, and what we're aiming for today:
Our ground ops team completed fuel (RP-1) loading last night and began loading LN2 a little over an hour ago. We’re watching weather closely; currently, it looks good for our target takeoff time around 11 AM.
LN2 has been fully loaded and the flight crew is onboard. Off to a smooth start today.

Alrighty, here we go! Cosmic Girl, with LauncherOne underwing, has taken off from the runway at Mojave Air and Space Port. We’re flying out to what will be the drop point for our upcoming Launch Demo.
Today’s test is going well! We are verifying all of our systems and working our way through our procedures. All systems are healthy and conditions are nominal.
We’ve successfully completed our pull-up maneuver and simulated drop. Everything has looked good thus far on this capstone launch rehearsal. Cosmic Girl heading back to base.
Our flying launch pad has returned to base and our crew are all smiles. We’re putting the finishing touches on today’s successful cryogenic captive carry flight.
Beautiful pull-up maneuver today!
And here are a few more photos, courtesy of our chase plane.

That's a wrap on today's rehearsal, the final major test before our upcoming launch demo. We'll have more updates very soon — thanks for following along today! 🚀
