Manned Orbital Development System was created by the US Air Force Space System Division SSD in June 1962. It was to begin working on plans to use Project Gemini Gemini hardware as the first step in a new USAF US Air Force man in space program called MODS Manned Orbital Development System , a type of military space station that used Gemini spacecraft as ferry vehicles. The term Blue Gemini first showed up in August 1962 as part of a more specific proposal to fly six Gemini missions with Air Force pilots in a preliminary orientation and training phase of MODS. MODS was effectively superseded when the Manned Orbital Laboratory was announced in December 1963.

Refimprove date June 2009 The Fractional Orbital Bombardment System FOBS was a Soviet Union Soviet Intercontinental ballistic missile ICBM program in the 1960s that after launch would go into a low Earth orbit and would then de orbit for an attack. It had no range limit and the orbital flight path would not reveal the target location. This would allow a path to North America over the South Pole , hitting targets from the south, which is the opposite direction from which North American Aerospace Defense Command NORAD early warning systems are oriented. The Outer Space Treaty banned nuclear weapons in Earth orbit. However, it did not ban systems that were capable of placing weapons in orbit, and the Soviet Union avoided violating the treaty by conducting tests of its FOBS system without live warheads. The Soviets developed three missiles to employ FOBS, with only one entering service The orbital missile 8K69 also known as R 36orb was initially deployed in 1968, with the first regiment put on alert in 1969. The Global Rocket 1 , or GR 1, was cancelled due to engine problems. The R 46 missile R 46 was not developed, and eventually scrapped. The U.S. Defense Support Program early warning satellites, first launched in 1970, enabled the US to detect a FOBS launch.

Refimprove date January 2010 Air Combat Maneuvering Instrumentation ACMI systems record an aircraft s in flight data. They are often used by the military for aerial combat training and analysis. ACMI systems usually include 4 major subsystems. Subsystems Control and Computation The Control and Computation Subsystem CCS is usually a rack mounted personal computer running applications that calculate Time Space Position Information TSPI . Transmission Instrumentation The Transmission Instrumentation Subsystem TIS is firmware running at or near a communications tower on the range the aircraft are flying around. The TIS will have 1 9 remote interrogators remotes scattered throughout the range. One of these remotes is at the TIS, and is referred to as the remote at Master . Each remote interrogates an AIS pod see below loaded on each aircraft flying on range, and receives the response and relays it to the TIS. Airborne Instrumentation Antiquated ACMI systems triangulated each pod s position and relayed that TSPI back to the CCS. Modern ACMI systems no longer triangulate instead, a GPS unit is installed in each Airborne Instrumentation Subsystem AIS pod to calculate its own position, thereby relieving the CCS of the triangulation algorithm. The CCS now gets a complete TSPI message from the AIS pod via the TIS, and forwards this data to a display system. Advanced Display and Debriefing or Individual Combat Aircrew Display Advanced Display and Debriefing Subsystems ADDS are quickly vanishing and being replaced by Individual Combat Aircrew Display Systems ICADS because the ICADS software can run on any compatible personal computer. ICADS is the display software that receives data from the CCS and displays it in a three dimensional graphical user interface .

Refimprove date March 2008 File SRBsepfromDiscovery07042006.png thumb right Discovery rockets to orbital velocity, seen here just after booster separation An orbital spaceflight or orbital flight is a spaceflight ... one convention, the boundary of space . To remain in orbit at this altitude requires an orbital speed of 7.8 km s. Orbital speed is slower for higher orbits, but attaining them requires higher delta v . The expression orbital spaceflight is mostly used to distinguish from sub orbital spaceflight s, which are flights where apogee of a spacecraft reaches space but perigee is too low. Orbital ... font size smaller colspan 8 style text align center Orbital Human spaceflight Name Debut Launches manned ... 2003 3 Orbital spaceflight from Earth has only been achieved by launch vehicle s that use rocket ... orbital speed, but allows for atmospheric drag approximately 300 m s with the ballistic coefficient ... until orbital velocity is achieved. Currently, 2 4 Multistage rocket stages are needed to achieve the required delta v. Most launches are by expendable launch system s. The Pegasus rocket for small satellites ...
