ULA

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. 🌎

LIVE: They are coming home. Watch as the Artemis II crew returns to Earth, splashing down at around 8:07pm ET (0007 UTC April 11). twitter.com/i/broadcasts/1…

Power. Performance. Precision. ULA again delivers for Amazon Leo. bit.ly/av_leo5 // @AmazonLeo

Humans are back in the Moon's neighborhood for the first time in more than 50 years. @NASAArtemis II is the first crewed lunar mission since 1972. This is one more step in NASA's path to establishing a long-term lunar presence for science and exploration. 📹: NASA

LAUNCH HIGHLIGHTS: The United Launch Alliance Atlas V rocket lifts off on Saturday, April 4 carrying Amazon Leo 5. The high-performance variant of the legendary rocket family successfully delivered its payload of 29 advanced broadband satellites into orbit, helping to connect the world. bit.ly/av_leo5 // @AmazonLeo Watch on YouTube: youtube.com/watch?v=wLEgJd…

Thank you, a great time to be in space!

Deployment confirmed: Another 29 Leo satellites have been successfully deployed in low Earth orbit, making it the heaviest payload ever launched on Atlas V. Thanks to @ulalaunch for a successful fifth mission together.

United Launch Alliance advances @AmazonLeo constellation with successful Leo 5 launch. Atlas V precisely delivered 29 broadband satellites dedicated to connecting the world. newsroom.ulalaunch.com/releases/unite…

United Launch Alliance has successfully completed today's launch of the Amazon Leo 5 mission by the Atlas V rocket! All 29 advanced broadband satellites have been released into low Earth orbit, marking the largest payload ever launched by the venerable rocket family. Atlas V has delivered a total of 139 Amazon spacecraft into orbit through six successful flights -- Protoflight and five launches for the Leo constellation. Next up, Leo 6 with another 29 satellites, is planned for April 27. bit.ly/av_leo5 // @AmazonLeo

Main engine cutoff, or MECO, is confirmed for the Centaur upper stage. The Atlas V rocket has achieved its low Earth orbit with the Amazon Leo Atlas 5 mission. bit.ly/av_leo5

Successful Atlas staging is confirmed as the rocket passes off the coast of Cape Hatteras, North Carolina at an altitude of 140 miles. The Centaur upper stage continues the ascent by accelerating the Amazon Leo payload to orbit. The vehicle now weighs less than seven percent of its liftoff mass. bit.ly/av_leo5

Atlas V has exited Earth's atmosphere and crossed the Karman line, allowing the payload fairing to be jettisoned. The rocket is over 115 miles downrange from the launch pad and traveling more than 7,000 mph. bit.ly/av_leo5

Solid rocket booster burnout and jettison is confirmed. The five GEM 63s consumed a half-million pounds (227,000 kg) of propellant to augment the initial liftoff power of the Atlas V. The rocket now weighs half of what it did at liftoff less than two minutes ago. bit.ly/av_leo5

LIFTOFF of the United Launch Alliance Atlas V for @AmazonLeo, taking the rocket's largest and heaviest payload ever into space! And the vehicle has cleared the tower! bit.ly/av_leo5

GO for launch! The final readiness poll by Launch Conductor Scott Barney is complete and Launch Director Bryan Titus has given final permission to launch our fifth @AmazonLeo mission! GO ATLAS! GO CENTAUR! GO AMAZON LEO! Watch the live launch webcast here: bit.ly/av_leo5

Atlas V is fully fueled and configured for today's Amazon Leo 5 mission that will advance our customer's mission to provide fast, reliable internet to communities around the world. Clocks are holding at T-minus 4 minutes for a 30-minute, 30-second planned built-in hold before final readiness polls and proceed toward our new launch time of 1:46 a.m. EDT (0546 UTC). Live launch webcast is about to begin. Tune in! bit.ly/av_leo5

Atlas V fueling is underway with cryogenic propellants for today's Amazon Leo 5 launch. Atlas and Centaur propulsion console operators here at ULA's Launch Control Center are performing the steps to command the pad systems to begin flowing 66,000 gallons of liquid oxygen and liquid hydrogen in the rocket over the next 90 minutes. Weather forecast is 90% favorable to launch at 1:45 a.m. EDT (0545 UTC). bit.ly/av_leo5 // @AmazonLeo
