Apollo Launch Escape System diagram. If the rocket failed in the last five minutes before launch, the CM and the launch escape system (LES, see figure) would separate from the remainder of the rocket below with the LES propelling itself and the CM beneath it upward and eastward to the sea using a small solid-fueled motor (the launch escape motor) at the top of the tower on the launch escape ...
A launch status check, also known as a "go/no go poll" and several other terms, occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed.
There are software packages associated with each domain. The 1990 edition of the Los Alamos Accelerator Code Group's compendium [1] provides summaries of more than 200 codes. Certain codes are still in use today, although many are obsolete. Another index of existing and historical accelerator simulation codes is located at the CERN CARE/HHH ...
Earth has a radius of 6,357 km (at the poles) making = 6,357,000 m and the satellites have an altitude of 20,184 km [15] making their orbit radius = 26,541,000 m. Substituting these in the above equation, with Earth mass M = 5.974 × 10 24 , G = 6.674 × 10 −11 , and c = 2.998 × 10 8 (all in SI units), gives:
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

The Transit system, also known as NAVSAT or NNSS (for Navy Navigation Satellite System), was the first satellite navigation system to be used operationally. The radio navigation system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for ...
Vostok 1 (Russian: Восток, lit. ' East ' or ' Orient ') was the first spaceflight of the Vostok programme and the first human orbital spaceflight in history. The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on 12 April 1961, with Soviet cosmonaut Yuri Gagarin aboard, making him the first human to reach orbital velocity around the Earth and to complete a full orbit ...
