Inertial Upper Stage
The Inertial Upper Stage (IUS), originally designated the Interim Upper Stage, was a Multistage rocket, two-stage, Solid-propellant rocket, solid-fueled space launch system developed by Boeing for the United States Air Force beginning in 1976 for raising payloads from low Earth orbit to higher orbits or interplanetary trajectories following launch aboard a Titan 34D or Titan IV rocket as its upper stage, or from the payload bay of the Space Shuttle as a space tug. Development During the development of the Space Shuttle, NASA, with support from the Air Force, wanted an upper stage that could be used on the Shuttle to deliver payloads from low earth orbit to higher energy orbits such as geostationary transfer orbit, GTO or geostationary orbit, GEO or to escape velocity for planetary probes. The candidates were the Centaur (rocket), Centaur, propelled by liquid hydrogen and liquid oxygen, the Transtage, propelled by hypergolic storable propellants Aerozine-50 and dinitrogen tetroxide ...

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ...

STS-51-C
STS-51-C (formerly STS-10) was the 15th flight of NASA's Space Shuttle program, and the third flight of Space Shuttle ''Discovery''. It launched on January 24, 1985, and made the fourth shuttle landing at the Shuttle Landing Facility at the Kennedy Space Center in Florida on January 27, 1985. STS-51-C was the first shuttle mission dedicated to the United States Department of Defense (DoD), and consequently many details remain classified. NASA reported that a satellite ( USA-8) was deployed during the mission using an Inertial Upper Stage booster was deployed and met mission objectives. At just over three days, the mission was shorter in duration than most civilian missions and was the shortest of ''Discovery''s career. Crew Backup crew Crew seat assignments Mission summary STS-51-C launched from Kennedy Space Center (KSC) on January 24, 1985, at 19:50:00 UTC, and was the first of nine shuttle missions in 1985.

Liquid Hydrogen
Liquid hydrogen () is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecule, molecular H2 form. To exist as a liquid, H2 must be cooled below its critical point (thermodynamics), critical point of 33 Kelvins, K. However, for it to be in a fully liquid state at atmospheric pressure, H2 needs to be cooled to .IPTS-1968
iupac.org, accessed 2020-01-01
A common method of obtaining liquid hydrogen involves a compressor resembling a jet engine in both appearance and principle. Liquid hydrogen is typically used as a concentrated form of hydrogen storage. Storing it as liquid takes less space than storing it as a gas at normal temperature and pressure. However, the liquid density is very low compared to other common fuels. Once liquefied, it can be maintained as a liquid for some time in the ...

Space Shuttle Seating Plan
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as ''spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a better model f ...

Manned Spaceflight Engineer Program
The Manned Spaceflight Engineer Program was an effort by the United States Air Force to train American military personnel as payload specialists for United States Department of Defense missions on the Space Shuttle program. Background The United States Air Force (USAF) and the National Reconnaissance Office (NRO) of the United States Department of Defense (DoD) participated in the development of the Space Shuttle from its official inception in 1969. To save money, the shuttle was intended to serve as the United States' national launch system for all civilian, military, and classified payloads. The DoD influenced key aspects of the shuttle's design such as the size of its cargo bay, and Congress reportedly told DoD that it would not pay for satellites not designed to fit into the bay. The USAF in the 1970s hoped to buy up to three shuttles and fly them with all-military crews. As with the earlier X-20 Dyna-Soar and Manned Orbiting Laboratory, budget concerns ended the "Blue Shuttle ...
