ULA

Atlas V rolled from the VIF to the pad at SLC-41 with another 29-satellite Leo payload, exactly 23 days after our last mission with @ULAlaunch. Leo Atlas 6 (LA-06) is scheduled to liftoff tonight, Apr 27, at 8:52 p.m. ET. ULA is using a streamlined roll-to-launch flow for this mission, with rollout, testing, fueling, and liftoff all within a single countdown. The process helps enable a faster turnaround between missions, allowing for a higher launch cadence as we prepare to transition from Atlas V to Vulcan. We’re now on the second of four back-to-back Leo launches on Atlas V, building steady momentum as we expand our constellation.

ULA's Roll & Preps Crew moved the Atlas V 551 rocket to Space Launch Complex-41 this morning to deliver Amazon's next 29 broadband satellites into space later tonight. Liftoff time is 8:52 p.m. EDT (0052 UTC). ULA is proceeding with a continuous roll-and-launch in a single-day countdown, part of our efforts to increase launch cadence for our @AmazonLeo customer. This effort reduces the amount of time the rocket spends at the pad, enabling launch to occur sooner. bit.ly/av_leo6

United Launch Alliance has initiated the countdown for launch of our sixth Atlas V 551 rocket to advance the Amazon Leo broadband constellation. But this countdown is unlike Atlas V launches you are accustomed to. Over the next 18 hours, we will move the 20-story rocket from the Vertical Integration Facility (VIF) to the pad, perform all of the necessary testing, load propellant and launch the mission. This is part of ULA's efforts to increase launch day efficiency and maximize launch opportunities while continuing our commitment to Amazon Leo. It increases launch cadence by reducing the amount of time that the rocket spends at the pad. Tonight's launch time is 8:52 p.m. EDT (0052 UTC) from Cape Canaveral. The weather forecast has improved to 85% GO. bit.ly/av_leo6 // @AmazonLeo

The U.S. Space Force weather squadron at Cape Canaveral predicts a 75 percent chance of acceptable weather for the United Launch Alliance Atlas V rocket launch of the @AmazonLeo mission on Monday at 8:52 p.m. EDT (0052 UTC). Full details: bit.ly/av_leo6

The ULA Launch Readiness Review is GO to continue preps for launch of Atlas V with our sixth Amazon Leo constellation mission. Liftoff is planned for Monday, at 8:52 p.m. EDT (0052 UTC) from Cape Canaveral. Early weather forecast is 75% favorable. The evening launch will be visible from Florida to New England, if weather conditions in your area permit. This visibility map shows when and where your best chances are to see the rocket as it streaks northeasterly into space. ULA will offer live reports from launch control in our automatically refreshing blog beginning at 5:45 p.m. EDT (2145 UTC). The launch livestream starts at 20 minutes before liftoff. bit.ly/av_leo6 // @AmazonLeo

Happy Earth Day 🌎

On Sunday morning, Atlas V received its payload of 29 satellites for the next United Launch Alliance mission to space for Amazon. The Leo 6 launch enables expansion of Amazon Leo constellation to provide fast, reliable internet to communities around the world. bit.ly/av_leo6 // @AmazonLeo

Extremely precise performance and injection accuracy. Contributing to “SLS’s 99.92 percent accuracy” (John Honeycutt, PM of SLS) – The ICPS, built in collaboration with @BoeingSpace, performed two burns to place Orion into a high Earth orbit, lofting the astronauts towards their lunar trajectory. Bullseye!

Let's do it again! A week after successfully launching our fifth Atlas V rocket for Amazon Leo, ULA ground crews have begun preparing for the Leo 6 mission. We will be launching another 29 advanced broadband satellites into space for our customer using the Atlas V 551 rocket later this month. bit.ly/av_leo6 // @AmazonLeo

Welcome home! Congratulations on a safe, successful mission and return to Earth. 🌎
