The Satellite Control Network was originally activated to support the CORONA (Discoverer) program in 1959. An interim satellite control center was initially established in Palo Alto, California, and by June 1960, a permanent control center had been established Sunnyvale AFS, later renamed Onizuka AFS, Sunnyvale, California.
6 hours, 24 minutes Replaced a Remote Power Control (RPC) module, and tested shuttle thermal tile repair materials and techniques. Removed a cover from the left arm of Dextre, and removed launch locks from the Harmony module. Released launch locks on Harmony's port and nadir Common Berthing Mechanisms (CBM). [126] 109. STS-123 EVA 5: Michael ...
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.
Small station-keeping orbital maneuvers were executed approximately monthly to maintain the spacecraft in the station-keeping orbit. [1] The James Webb Space Telescope will use propellant to maintain its halo orbit around the Earth-Sun L2, which provides an upper limit to its designed lifetime: it is being designed to carry enough for ten years ...
The computer was architecturally similar to the Saturn Launch Vehicle Digital Computer, in particular in the instruction set; [6] however its circuit integration was less advanced. [7] The GGC weighed 58.98 pounds (26.75 kg) and was powered by 28V DC. During a short power outage it could be powered by the Auxiliary Computer Power Unit (ACPU)
Vandenberg Space Launch Complex 6 (SLC-6, pronounced "Slick Six") is a launch pad and associated support infrastructure at Vandenberg Space Force Base in California. Construction at the site began in 1966, but the first launch didn't occur until 1995 due to program cancellations and subsequent repurposing efforts.
O3b mPOWER is a communications satellite system owned and operated by SES.The system uses high-throughput and low-latency satellites in a medium Earth orbit (MEO), along with ground infrastructure and intelligent software, to provide multiple terabits of global broadband connectivity for applications including cellular backhaul and international IP trunking, cruise line connectivity, disaster ...
The Mobile Remote Servicer Base System (MBS) is a base platform for the robotic arms. It was added to the station during STS-111 in June 2002. The platform rests atop the Mobile Transporter [6] (installed on STS-110, designed by Northrop Grumman in Carpinteria, CA), which allows it to glide 108 metres down rails on the station's main truss.
