CENTENNIAL, Colo., May 20, 2019 (ULA PR) – United Launch Alliance leaders and engineers completed an important milestone with the conclusion of the system Critical Design Review (CDR) for the company’s new Vulcan Centaur rocket. The system-level CDR is the final review of the design for the overall rocket.
Centennial, Colo., April 8, 2019 (ULA PR) – Today, United Launch Alliance (ULA) CEO Tory Bruno gave an update on the continued progress of the Vulcan Centaur during a ULA media event at the 35th Space Symposium.
“As the nation faces growing threats in the space environment, ULA is unleashing the energy of American ingenuity by developing the Vulcan Centaur,” said Bruno. “Purpose built to meet our nation’s needs for expanding space missions, the Vulcan Centaur’s innovative technology is transforming the future of launch and will advance America’s superiority in space.”
Cape Canaveral Air Force Station, Fla., March 15, 2019 (ULA PR) – A United Launch Alliance (ULA) Delta IV rocket carrying the tenth Wideband Global SATCOM (WGS) satellite for the U.S. Air Force lifted off from Space Launch Complex-37 on March 15 at 8:26 p.m. EDT. ULA has been the exclusive launch provider for all ten WGS satellites.
CAPE CANAVERAL AIR FORCE STATION, Fla. (ULA PR) — Everything is progressing toward the ULA Delta IV launch carrying the WGS-10 mission for the U.S. Air Force. The mission is set to lift off on Friday, March 15 from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida.
Today’s forecast shows a 70 percent chance of favorable weather conditions for launch. The launch window begins at 6:56 p.m. ET and extends to 9:05 p.m. ET.
IUKA, Miss. (Northrop Grumman PR) — In a small Mississippi town, a group of scientists and engineers recently gathered to discuss their next project: building large aerospace composite structures for Northrop Grumman’s new OmegA rocket. OmegA is being designed to launch the U.S. Air Force’s most critical spacecraft for U.S. national security missions.
GREENBELT, Md. (NASA PR) — Early on an August morning, the sky near Cape Canaveral, Florida, will light up with the launch of Parker Solar Probe. No earlier than Aug. 6, 2018, a United Launch Alliance Delta IV Heavy will thunder to space carrying the car-sized spacecraft, which will study the Sun closer than any human-made object ever has.

The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
The draft environmental assessment for SpaceX’s proposed expansion at NASA’s Kennedy Space Center (KSC) also revealed that Elon Musk’s rocket company plans to most of more than 4,000 satellites of its planned Starlink constellation from Cape Canaveral.
That will guarantee a busy schedule for SpaceX’s Launch Complex 39A (LC-39A) at KSC and LC-40 at the adjoining Cape Canaveral Air Force Station (CCAFS). LC-39A can accommodate Falcon 9 and Falcon Heavy boosters while LC-40 is configured for the Falcon 9.

Evolved Expendable Launch Vehicle (EELV) Program
Technology Maturity, Design Stability, and Production Readiness
All but one (14 of 15) of ULA’s launch vehicle variants—which are based on payload fairing size and number of strap-on solid rocket boosters used—and two variants of SpaceX’s Falcon 9 have flown at least once, demonstrating technology maturity. For design stability and production readiness, the program assesses launch vehicles using Aerospace Corporation’s “3/7 reliability rule.” Once a variant is launched successfully three times, its design can be considered stable and mature. Similarly, if a variant is successfully launched seven times, both the design and production process can be considered stable and mature.
VANDENBERG AIR FORCE BASE, Calif., Jan. 12, 2018 (ULA PR) – A United Launch Alliance (ULA) Delta IV rocket carrying a payload for the National Reconnaissance Office (NRO) lifted off from Space Launch Complex-6 on Jan. 12 at 2:11 p.m. PST. Designated NROL-47, the mission is in support of national defense.
Vandenberg Air Force Base, Calif. Jan. 11, 2018 (ULA PR) – The launch of a United Launch Alliance Delta IV carrying the NROL-47 mission was scrubbed today due to an issue with a ground system valve.
The launch is planned for Friday, Jan. 12, from Space Launch Complex-6 at Vandenberg Air Force Base. The forecast shows a 90 percent chance of favorable weather conditions for launch. The launch time is 1:00 p.m. PT.
SpaceShipTwo Flies: Virgin Galactic’s SpaceShipTwo Unity performed its seven glide flight this morning in Mojave. The flight appeared to go as planned based on what I could see from the ground and Virgin Galactic’s tweets; the space plane landed and rolled to a stop on runway 30. The pilots were Mark Stucky and Michael Masucci.
This is the seventh glide flight for Unity and the 37th glide test for the SpaceShipTwo program. Its predecessor, Enterprise, flew 30 glide and three powered flights before it broke up during its fourth powered flight on Oct. 31, 2014.
Virgin Galactic officials have said today’s test should be the final glide flight for Unity. If all went well, the next test will be powered.
UPDATE: Virgin Galactic has posted a description of today’s flight here.
SpaceX Scrubs: SpaceX scrubbed a static fire of the Falcon Heavy booster for the second time in as many days at NASA’s Kennedy Space Center. The company planned a 12- to 15-second firing of the 27 first stage engines of the heavy-lift rocket. No reason has been given for the scrub. Reports indicate that a third attempt is set for Friday. If the same schedule is maintained, the six-hour test window will open at 1 p.m. EST.
Delta IV Launch Set: United Launch Alliance is planning to launch a Delta IV booster with the NROL 47 reconnaissance satellite from Vandenberg this afternoon. The original launch time was set for 1 p.m. PST, but ULA says it is working a technical issue that will delay the launch until later. No new time as been set yet. The launch was scrubbed on Wednesday due to high winds.
UPDATE: Liftoff is now planned for 1:55 p.m. PST. Webcast commentary will start at 1:30 p.m. PST. UPDATE 2: Liftoff now at 2:05 p.m. PST.
Chinese & Indian Launches Scheduled: A Chinese Long March 3B rocket will launch two Beidou navigation satellites at approximately 2300 GMT (6 p.m. EST) today. The flight will be conducted from the Xichang Satellite Launch Center.
India’s PSLV booster will launch the Cartosat 2F remote sensing satellite from Satish Dhawan Space Center on Friday at 0358 GMT (10:58 p.m. EST on Thursday, Jan. 11). It will be the first PSLV launch since August when a failure of the payload shroud to separate doomed an IRNSS-1H navigation satellite to a fiery destruction.
A Long March 2D rocket is set to launch an unidentified satellite from Jiuquan on Saturday at approximately 0710 GMT (2:10 a.m. EST). This will be China’s third launch of the new year.

SpaceX had a banner year in 2017, launching a record 18 times and helping to propel the United States to the top of the global launch table with a perfect 29-0 record. The U.S. total made up 32.2 percent of 90 orbital launches worldwide, which was an increase over the 85 flights conducted in 2016.
The 29 American launches were a leap of seven over the 22 flights conducted the previous year. This is the highest number of American orbital launches since the 31 flights undertaken in 1999. However, that year the nation’s launch providers suffered four failures whereas they were perfect in 2017.
