KickSat
KickSat was a satellite dispenser for small-satellite ( femtosatellite) project inaugurated in early October 2011, to launch many very small satellites from a 3U CubeSat. The satellites have been characterized as being the size of a large postage stamp. and also as "cracker size". The mission launch was originally scheduled for late 2013 and was launched April 18, 2014. Kicksat reached its orbit and transmitted beacon signals that were received by radio amateurs. Telemetry data allowed the prediction of the orbit and the reentry on May 15, 2014, at about 01:30 UTC. Due to a non-redundant design, a timer reset while on-orbit and the femtosatellites were not deployed in time, and burned up inside the KickSat mothership when the undeployed satellite-deployment mechanism reentered Earth's atmosphere. It is one of several crowdfunded satellites launched during the 2010s. History The project was crowdfunded through Kickstarter. The project was advertised with the goal of reducing ...

Miniaturized Satellite
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

SpaceX CRS-3
SpaceX CRS-3, also known as SpX-3, was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 18 April 2014. It was the fifth flight for SpaceX's uncrewed Dragon cargo spacecraft and the third SpaceX operational mission contracted to NASA under a Commercial Resupply Services (CRS-1) contract. This was the first launch of a Dragon capsule on the Falcon 9 v1.1 launch vehicle, as previous launches used the smaller v1.0 configuration. It was also the first time the F9 v1.1 has flown without a payload fairing, and the first experimental flight test of an ocean landing of the first stage on a NASA/Dragon mission. The Falcon 9 with CRS-3 on board launched on time at 19:25 UTC on 18 April 2014, and was grappled on 20 April at 11:14 UTC by Expedition 39 commander Koichi Wakata. The spacecraft was berthed to the ISS from 14:06 UTC on that day to 11:55 UTC on 18 May 2014. CRS-3 then successfully de-orbited and splash ...

Breakthrough Starshot
Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named ''Starchip'', to be capable of making the journey to the Alpha Centauri star system 4.37 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark Zuckerberg. A flyby mission has been proposed to Proxima Centauri b, an Earth-sized exoplanet in the habitable zone of its host star, Proxima Centauri, in the Alpha Centauri system. At a speed between 15% and 20% of the speed of light, it would take between twenty and thirty years to complete the journey, and approximately four years for a return message from the starship to Earth. The conceptual principles to enable this interstellar travel project were described in "A Roadmap to Interstellar Flight", by Philip Lubin of UC Santa Barbara.(file available at University of California, Santa Barbarhere Accessed 16 April 2016) Sending the ...

Crowdfunded Satellites
Crowdfunded satellites are artificial satellites that have been funded by using crowdfunding, rather than more traditional methods of financing. Several crowdfunded satellites have been launched in the 2010s, including SkyCube, KickSat, ArduSat, all of which resulted from successful Kickstarter campaigns, and the Russian Mayak,{{Cite web, url=https://www.calvertjournal.com/news/show/8606/russian-students-launch-crowdfunded-satellite, title=Russian students launch crowdfunded satellite, last=Morton, first=Elise, date=17 July 2017, website=The Calvert Journal, language=en, archive-url=, archive-date=, access-date=2019-01-05 which used the Russian Boomstarter platform.

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.

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Interplanetary Society
The British Interplanetary Society (BIS), founded in Liverpool in 1933 by Philip E. Cleator, is the oldest existing space advocacy organisation in the world. Its aim is exclusively to support and promote astronautics and space exploration. Structure It is a non-profit organisation with headquarters in London and is financed by members' contributions. It is situated on South Lambeth Road ( A203) near Vauxhall station. History The BIS was only preceded in astronautics by the American Interplanetary Society (founded 1930), the German VfR (founded 1927), and Soviet Society for Studies of Interplanetary Travel (founded 1924), but unlike those it never became absorbed into a national industry. Thus it is now the world's oldest existing space advocacy body. When originally formed in October 1933, the BIS aimed not only to promote and raise the public profile of astronautics, but also to undertake practical experimentation into rocketry along similar lines to the organisations ...

Materials International Space Station Experiment
The Materials International Space Station Experiment (MISSE) is a series of experiments mounted externally on the International Space Station (ISS) that investigates the effects of long-term exposure of materials to the harsh space environment. The MISSE project evaluates the performance, stability, and long-term survivability of materials and components planned for use by NASA, commercial companies and the Department of Defense (DOD) on future low Earth orbit (LEO), synchronous orbit and interplanetary space missions. The Long Duration Exposure Facility (LDEF), which was retrieved in 1990 after spending 68 months in LEO, revealed that space environments are very hostile to many spacecraft materials and components. Atomic oxygen, which is the most prevalent atomic species encountered in low earth orbit, is highly reactive with plastics and some metals, causing severe erosion. There is also extreme ultraviolet radiation due to the lack of an atmospheric filter. This radiation det ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
