For launch the wind constraints at the launch pad varied slightly for each mission. The peak wind speed allowable was 34 knots (63 km/h; 39 mph). However, when the wind direction was between 100 degrees and 260 degrees, the peak speed varies and may be as low as 20 knots (37 km/h; 23 mph).
Two-person rule. Sealed Authenticator System safe at a missile launch control center with two crew locks. The two-person rule is a control mechanism designed to achieve a high level of security for especially critical material or operations. Under this rule, access and actions require the presence of two or more authorized people at all times.
The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.
The NASA inspector general now reports that the launcher will not be ready in time for the planned rocket launch. To make matters worse, due to design changes, more cost increases are expected.
The Nuremberg Code (German: Nürnberger Kodex) is a set of ethical research principles for human experimentation created by the court in U.S. v Brandt, one of the Subsequent Nuremberg trials that were held after the Second World War. Though it was articulated as part of the court's verdict in the trial, the Code would later become significant ...
Launch vehicle system tests. Launch vehicle system tests assess the readiness of a launch system to safely reach orbit. Launch vehicles undergo system tests before they launch. Wet dress rehearsals (WDR) and more extensive static fire tests prepare fully assembled launch vehicles and their associated ground support equipment (GSE) prior to launch.
SpaceX CRS-4 →. SpaceX CRS-3, also known as SpX-3, [4] was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 18 April 2014.
