Satellite Dispenser
A satellite dispenser is a space tug usually released from the upper stage (sometimes called kick stage) of a rocket and designed to fly small secondary payloads to their desired location before deploying them. Project West Ford launched 480,000,000 needles in space in 1961 and 1963 using a dispenser. The company Moog Inc. launched a satellite dispenser on a Falcon 9 rocket on 14 July 2014, placing 6 Orbcomm satellites in orbit. SHERPA (space tug), SHERPA is a satellite dispenser first launched on 3 December 2018 on a rideshare mission called ''SSO-A: SmallSat Express''. The two SHERPA dispensers placed a number of 64 satellites, after separating from the Falcon 9 Block 5 rocket once it entered a polar Sun-synchronous orbit around 575 kilometers above Earth.

Space Tug
''Space Tug'' is a young adult science fiction novel by author Murray Leinster. It was published in 1953 by Shasta Publishers in an edition of 5,000 copies. It is the second novel in the author's Joe Kenmore series. Groff Conklin gave it a mixed review in ''Galaxy'', noting that it held "plenty of excitement though not much maturity." Boucher and McComas preferred it to the series's initial volume, but still found it "quite a notch below ... Leinster's adult work." P. Schuyler Miller reported the novel was marked by "the fastest kind of action" and "the feeling of technical authenticity.""The Reference Library", ''Astounding Science Fiction'', November 1954, p.144 Plot introduction The novel concerns the problems of the running of a space station.

Project West Ford
Project West Ford (also known as Westford Needles and Project Needles) was a test carried out by Massachusetts Institute of Technology's Lincoln Laboratory on behalf of the United States military in 1961 and 1963 to create an artificial ionosphere above the Earth. This was done to solve a major weakness that had been identified in military communications. History At the height of the Cold War, all international communications were either sent through submarine communications cables or bounced off the natural ionosphere. The United States military were concerned that the Soviets might cut those cables, forcing the unpredictable ionosphere to be the only means of communication with overseas forces. To mitigate the potential threat, Walter E. Morrow started Project Needles at the MIT Lincoln Laboratory in 1958. The goal of the project was to place a ring of 480,000,000 (Abstract) copper dipole antennas in orbit to facilitate global radio communication. The dipoles collectively pr ...

Falcon 9
Falcon 9 is a partially reusable medium lift launch vehicle that can carry cargo and crew into Earth orbit, produced by American aerospace company SpaceX. The rocket has two stages. The first (booster) stage carries the second stage and payload to a certain altitude, after which the second stage lifts the payload to its ultimate destination. The rocket evolved through several versions. V1.0 flew from 2010–2013, V1.1 flew from 2013–2016, while V1.2 Full Thrust first launched in 2015, encompassing the Block 5 variant, flying since May 2018. The booster is capable of landing vertically to facilitate reuse. This feat was first achieved on flight 20 in December 2015. Since then, SpaceX has successfully landed boosters over 100 times. Individual boosters have flown as many as 15 flights. Both stages are powered by SpaceX Merlin engines, using cryogenic liquid oxygen and rocket-grade kerosene (RP-1) as propellants. The heaviest payloads flown to geostationary transfer or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
