A flight spare is a copy of a spacecraft or spacecraft part which is held in reserve in case it is needed for the mission. Flight spares are built to the same specifications as the original equipment (the "flight model"), and can be substituted in the case of damage or other problems with the flight model, reducing launch delays.
The second objective of STS-41-C was to capture, repair and redeploy the malfunctioning Solar Maximum Mission satellite ("Solar Max"), which had been launched in 1980. On the second day of the flight, the LDEF was grappled by the Remote Manipulator System and successfully released into orbit. Its 57 experiments, mounted in 86 removable trays ...
Satellite formation flying is the coordination of multiple satellites to accomplish the objective of one larger, usually more expensive, satellite. [1] Coordinating smaller satellites has many benefits over single satellites including simpler designs, faster build times, cheaper replacement creating higher redundancy, unprecedented high resolution, and the ability to view research targets from ...
The Flight-Releasable Grapple Fixture (FRGF) is the simplest variation of the North American grapple fixture, it allows only for grappling and does not have any electrical connectors. [4] Its use began early in the Space Shuttle program and was developed from the Flight Standard Grapple Fixture (FSGF) by allowing the Grapple Shaft to be ...
On-orbit satellite servicing refers to refueling or repairing space satellites while in orbit. [1]New commercial interest in on-orbit servicing of satellites is in large part due to the decreased costs of launching commercial satellites and the rise of low orbit, rather than geostationary, satellites for which servicing costs less.
Jan. 8—Kit Samson, a Philippine-born pianist who played a 23-year engagement with his band, Kit Samson's Sound Advice, at the Kalaha Hilton Hotel, died Dec. 20 after several years of declining ...
2-way DiSEqC switch 4-way DiSEqC switch with attached coaxial cables.. DiSEqC (/ ˈ d aɪ s ɛ k, d aɪ ˈ s ɛ k s i /; [citation needed] short for Digital Satellite Equipment Control) is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small [1] dish antenna rotor.
The Samson Switchblade is an American amateur-built roadable aircraft, under development by Samson Motorworks of Meadow Vista, California. It was publicly introduced at AirVenture in 2009 in mock-up form. The aircraft is intended to be supplied as a kit for amateur construction initially and possibly as a complete ready-to-fly-aircraft in the ...
