Launch commit criteria are the criteria which must be met in order for the countdown and launch of a space shuttle or other launch vehicle to continue. These criteria relate to safety issues and the general success of the launch, as opposed to ''supplemental data''.〔(The Space Shuttle Launch Team )〕 ==Atlas V== Launch commit criteria for Atlas V launches are similar to those used for the Atlas V launch of the Mars Science Laboratory Some can be overridden if additional requirements are met.〔(Atlas V MSL Weather Criteria )〕 * wind at the launch pad exceeds * ceiling less than or visibility less than * upper-level conditions containing wind shear that could lead to control problems for the launch vehicle. * cloud layer greater than thick that extends into freezing temperatures * cumulus clouds with tops that extend into freezing temperatures within * of the edge of a thunderstorm that is producing lightning for 30 minutes after the last lightning is observed. * field mill instrument readings within of the launch pad or the flight path exceed +/- 1,500 volts per meter for 15 minutes after they occur * thunderstorm anvil is within of the flight path * thunderstorm debris cloud is within or fly through a debris cloud for three hours * Do not launch through disturbed weather that has clouds that extend into freezing temperatures and contain moderate or greater precipitation, or launch within of disturbed weather adjacent to the flight path * Do not launch through cumulus clouds formed as the result of or directly attached to a smoke plume 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Launch commit criteria」の詳細全文を読む スポンサード リンク
