UNITED LAUNCH ALLIANCE

A behind-the-scenes look as ULA teammates re-engineer Santa's sleigh to meet mission requirements. Wishing you every happiness as we launch into 2019!

Watch live at ULA's Delta IV Heavy rocket blasts off with the NROL-71 mission for the National Reconnaissance Office.

If you've ever seen a Delta IV Heavy rocket lift off, you may have notice that it seems to emerge from a cloud of fire. ULA's Tyler Strickland talks with propulsion engineer Kris Kolman to learn more.

United Launch Alliance will use a Delta IV Heavy rocket to launch the NROL-71 mission for the National Reconnaissance Office. The launch is scheduled for 12/7 at 8:19 p.m. PDT. This will be 132nd mission for United Launch Alliance and ULA's second Delta IV Heavy launch in less than four months. It is the 382nd Delta launch since 1960, the 38th for a Delta IV rocket since 2002 and the 11th Delta IV Heavy.

ULA challenged our employees to create videos for a “film festival” earlier this year — to create videos around the theme “Save Lives.” Congratulations to Sanel Babic, who is the runner up with his video.

An elite group of United Launch Alliance specialists will serve as an ascent flight control team during launches of Boeing’s Starliner spacecraft aboard Atlas V rockets. Stationed in the Vehicle Ascent and Launch Operations Room (VALOR) at ULA’s Denver headquarters this dedicated team will monitor the health and performance of the Atlas V rocket during every Starliner capsule’s climb to space.

Rocket's eye view of the ULA Atlas V rocket's successful launch of the fourth Advanced Extremely High Frequency (AEHF) mission for the U.S. Air Force. The mission marked ULA's 50th for the Air Force and the 250th flight of the Centaur upper stage.

The Oct. 17, 2018, launch of the AEHF-4 mission marked the 250th flight for the high-energy, fully cryogenic Centaur upper stage. ULA's Rick Beach, Greg Arend and George Kontogiannis talk about the design and evolution of the world's most efficient upper stage.

A United Launch Alliance (ULA) Atlas V rocket carrying the fourth Advanced Extremely High Frequency (AEHF) mission for the U.S. Air Force lifts off from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida, on Oct. 17, 2018. The launch of AEHF-4 marks ULA’s 50th launch for the U.S. Air Force.

Watch live as ULA's Atlas V rocket launches the fourth Advanced Extremely High Frequency (AEHF-4) satellite for the U.S. Air Force.

United Launch Alliance will use an Atlas V 551 rocket to launch the fourth communications satellite in the Advanced Extremely High Frequency (AEHF) series for the U.S. Air Force. The launch is scheduled for 10/17. The window opens at 12:15 a.m. EDT. AEHF satellites provide highly-secure, jam-proof connectivity between U.S. national leadership and deployed military forces. Atlas V rockets successfully launched the first three AEHF satellites in 2010, 2012 and 2013 as the new constellation was formed in geosynchronous orbit 22,300 miles above Earth. This will be 131st mission for United Launch Alliance and our 50th launch for the Air Force. It is the 79th for an Atlas V rocket and the 9th in the 551 configuration.

Rocket's eye view of NASA's Ice, Cloud and land Elevation Satellite (ICESat)-2 mission from ULA's Delta II rocket. Launched Sept. 15, 2018, ICESat-2 marked the Delta II's final mission, capping a 29-year run of 155 launches and 100 consecutive successful missions.

A United Launch Alliance (ULA) Delta II rocket carrying launch NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) mission lifts off from Space Launch Complex-2 at Vandenberg Air Force Base, California, on Sept. 15, 2018. ICESat-2 is the 155th and final launch of the Delta II rocket. From its origin as the launch vehicle for the first Global Positioning System (GPS) satellites to NASA’s Earth observing, science and interplanetary satellites including Mars rovers Spirit and Opportunity to vital commercial communication and imaging satellites, the Delta II rocket has truly earned its place in space history.

A United Launch Alliance Delta II Heavy rocket will launch NASA's Ice, Cloud and land Elevation-2 (ICESat-2) mission from Vandenberg Air Force Base, California. The ICESat-2 mission will be the final for the workhorse Delta II rocket, which has launched 154 times, including missions for the U.S. Air Force, NASA, the National Reconnaissance Office and commercial customers. Go Delta! Go ICESat-2!

ULA challenged our employees to create a “film festival” earlier this year — to create videos around the theme “Explore the Universe.” Congratulations to Rick Jones, runner up for our first competition for this video “Explore.”

ULA systems engineer Patrick Moore recently joined the Kerbal Space Academy to talk about the Parker Solar Probe mission and Delta IV Heavy rocket. Patrick provided realistic flight commentary as KSA instructor DasValdez launched his own “Deltish IV” rocket carrying a “Parker Sorta Probe”, built using stock parts in Kerbal Space Program.
