This followed the retirement of Delta II in 2018 and single-stick (non-Heavy) variants of the Delta IV in 2019. With the start of 2024, Vulcan Centaur took its first flight in time to maintain continuity of ULA's service in the heavy-lift launch vehicle market before the Delta IV Heavy program came to an end three months later on April 9, 2024.
The Delta IV Heavy ( Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024, behind NASA 's Space Launch System and SpaceX 's Falcon Heavy and closely followed by CASC 's Long March 5.

Delta Flight Museum. / 33.655043; -84.420127. The Delta Flight Museum is an aviation and corporate museum located in Atlanta, Georgia, United States, near the airline's main hub, Hartsfield–Jackson Atlanta International Airport. The museum is housed in two 1940s-era Delta Air Lines aircraft hangars at Delta's headquarters, designated a ...
Gravity loss. In astrodynamics and rocketry, gravity loss is a measure of the loss in the net performance of a rocket while it is thrusting in a gravitational field. In other words, it is the cost of having to hold the rocket up in a gravity field. Gravity losses depend on the time over which thrust is applied as well the direction the thrust ...
List of landings on extraterrestrial bodies. Coordinates: 80.13°S 1.44°E. This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts. The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an ...
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
Delta- v in feet per second, and fuel requirements for a typical Apollo Lunar Landing mission. In astrodynamics and aerospace, a delta-v budget is an estimate of the total change in velocity ( delta- v) required for a space mission. It is calculated as the sum of the delta-v required to perform each propulsive maneuver needed during the mission.
Convair XF-92. Developed into. F-106 Delta Dart. The Convair F-102 Delta Dagger [N 2] was an interceptor aircraft designed and produced by the American aircraft manufacturer Convair. A member of the Century Series, the F-102 was the first operational supersonic interceptor and delta-wing fighter operated by the United States Air Force (USAF).
