Since 1990, NASA has purchased expendable launch vehicle launch services directly from commercial providers, whenever possible, for its scientific and applications missions. Expendable launch vehicles can accommodate all types of orbit inclinations and altitudes and are ideal vehicles for launching Earth-orbit and interplanetary missions.
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA.As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory.
For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems. Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit.
NASA chose the RS-68 because of its lower cost, about $20 million per engine including the cost of NASA's upgrades. The upgrades included a different ablative nozzle to accommodate a longer burn, a shorter start sequence, hardware changes to limit free hydrogen at ignition, and a reduction in the amount of helium used during countdown and flight.
The most recent TDRS launch was in January 2013 (TDRS-K) from CCAFS. Kodiak Star (Athena I) & Lunar Prospector (Athena II) The Athena I vehicle carried NASA's Kodiak Star mission into orbit Sept. 29, 2001, from the Kodiak Launch Complex in Alaska. NASA's Starshine 3 and three U.S. Department of Defense satellites were launched into different ...
The project goal is to examine the performance advantage, as well as the operational aspects, of a towed, airborne launch system. [ 4 ] According to Gerrard Budd, the development manager of NASA Armstrong Center's air launch program, "[NASA] thinks that [the glider] is the optimization for air launch", comparing the design of the system to ...
The Checkout, Control and Monitor Subsystem (CCMS) controls the actual processing and launch of the Space Shuttle. [4] This subsystem consists of the staffed consoles in the firing room, as well as minicomputers, and data transmission and recording systems, which monitor the pre-launch performance of all electrical and mechanical systems on board the Shuttle vehicle.
The RS-83 was developed by Rocketdyne Propulsion and Power in Canoga Park, California to power the launch vehicle as part of the Space Launch Initiative program. This engine was designed to produce a thrust of 664,000 lbf (2,950 kN) at sea level and 750,000 lbf (3,300 kN) in a vacuum with an I sp of 395 and 446 seconds (3.87 and 4.37 kN·s/kg ...
