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.
Delta Pyxidis (δ Pyxidis) is binary star system in southern constellation of Pyxis. Having an apparent visual magnitude of +4.877, [2] it is bright enough to be visible to the naked eye. Based upon an annual parallax shift of 13.19 mas as seen from Earth, [1] it is located around 250 light years from the Sun.

Delta Aquilae, Latinized from δ Aquilae, is a binary star system in the equatorial constellation of Aquila. It has an apparent visual magnitude of 3.4 [2] and, based upon parallax measurements, is located at a distance of about 50.6 light-years (15.5 parsecs) from Earth. [1] It is drifting closer with a radial velocity of −30 km/s. [6]
Delta Force bodyguards in civilian clothing providing close protection to General Norman Schwarzkopf during the Gulf War, 1991. Delta Force was created in 1977 after numerous well-publicized terrorist incidents led the U.S. government to develop a full-time counter-terrorism unit. Key military and government figures had already been briefed on ...
