Unlike NewtonThree, which burns only once per mission, NewtonFour completes multiple burns to ensure we deploy the satellites into their target orbits.
As planned, the upper stage has now shut down and will coast about halfway around Earth before the engine relights to complete the mission.
We're waiting for the rocket to coast halfway around Earth, deploy its payload, and downlink telemetry. Even when you're moving ~20,000 miles per hour, it takes a while to circle our planet! 🌎
We appear to have an anomaly that has prevented us from reaching orbit. We are evaluating the information.
As we find out more, we're removing our previous tweet about reaching orbit. We'll share more info when we can.
#CosmicGirl has returned safely back to @SpaceCornwall with our flight crew.

Our mission livestream will kick off as planned at 5:30 AM PDT/12:30 PM UTC — but we're targeting an updated takeoff time of ~6:50 AM PDT/1:50 PM UTC. We'll also live-tweet updates we progress through major milestones, so keep an eye on our feed here.
The primary for today’s mission is the @DeptofDefense Space Test Program, which is launching four R&D satellites for its first mission (STP-27VPA) on LauncherOne. #TubularBells

With operations for our #LaunchDemo2 mission already in full swing, it's an exciting morning here at Mojave Air and Space Port!

LOX loading on the rocket has begun, and we're looking good to hit our target takeoff time of approximately 10:30 AM Pacific.
As we move through our major milestones today, we'll keep you in the loop right here on Twitter. But first, a quick recap for anyone who's unfamiliar...
We are Virgin Orbit, the team opening space for good. We're driven by an ambition to smash down the barriers preventing affordable, responsive access to space.

And if you've seen our LauncherOne system, you'll know that we're doing launch a little differently from everyone else.

Our vehicles, hardware, and software are all ready to go. With two rehearsals already complete, one final wet dress rehearsal is all that remains for us to do. However, the Covid-19 pandemic is impacting our ability to safely operate, and thus our schedule.
Our team has really proven to be outstanding. In the past week, we’ve completed full mission duration hotfire campaigns on both our upper & main stage engines, qualified our flight software and mission planning for this flight, verified the health of all rocket systems, and more.
Through extensive use of remote work and PPE, the redesign of our launch operations, and well-trained and dedicated staff, we've done everything in our power to keep our team safe at work — and thus far, we've prevented any cases of teammate-to-teammate transmission.

Good morning, world! Today is a momentous occasion for the Virgin Orbit team: operations for the first orbital launch demonstration of our LauncherOne rocket are well underway. 🚀
After a promising pre-flight briefing this morning, weather remains favorable for our target launch window today.

As a reminder, we will not be livestreaming this flight — but stick around and refresh this feed for updates as the action happens.
Between the COVID-19 crisis and Memorial Day, it’s a bit of an odd time to be launching a rocket — but we’re thrilled to be approaching our first official launch window after years of working methodically through the LauncherOne program. We’re feeling more ready than ever.

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: virg.in/TFr
