CubeSat
A CubeSat is a class of miniaturized satellite based around a form factor consisting of cubes. CubeSats have a mass of no more than per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. , more than 1,600 CubeSats have been launched. In 1999, California Polytechnic State University (Cal Poly) professor Jordi Puig-Suari and Bob Twiggs, a professor at Stanford University Space Systems Development Laboratory, developed the CubeSat specifications to promote and develop the skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit (LEO) that perform a number of scientific research functions and explore new space technologies. Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, ...

ELA-1
ELA-1, short for Ensemble de Lancement Ariane 1 ( French for Ariane Launch Area 1), now named Ensemble de Lancement Vega (short ELV), is a launch pad at the Centre Spatial Guyanais in French Guiana. It has been used to support launches of the Europa rocket, Ariane 1, Ariane 3, and is currently used to launch Vega rockets. History Europa (BEC) ELA-1, at the time designated Base Équatoriale du CECLES (BEC) was constructed as an equatorial launch site for the Europa-II rocket which was being built as part of the ELDO programme. The first launch occurred on 5 November 1971. This was the only flight of the Europa-II, which ended in failure due to a guidance problem. The launch site was mothballed, and later demolished. Ariane (ELA) When the Ariane 1 programme was started, to replace the failed ELDO programme, a new launch site was built on the site of the former CECLES pad. This was designated Ensemble de Lancement Ariane (ELA). The first Ariane 1 launch occurred on 24 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Academy Of Sciences
The Polish Academy of Sciences ( pl, Polska Akademia Nauk, PAN) is a Polish state-sponsored institution of higher learning. Headquartered in Warsaw, it is responsible for spearheading the development of science across the country by a society of distinguished scholars and a network of research institutes.

Continuous Wave
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration. It may refer to e.g. a laser or particle accelerator having a continuous output, as opposed to a pulsed output. Continuous wave is also the name given to an early method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal, for example by Morse code in early radio. In early wireless telegraphy radio transmission, CW waves were also known as "undamped waves", to distinguish this method from damped wave signals produced by earlier ''spark gap'' type transmitters. Radio Transmissions before CW Very early radio transmitters used a spark gap to produce radio-frequency oscillations in the transmitting antenna. The signals produced by these spark-gap transmitters c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BRITE
BRITE-Constellation is an ongoing space mission carrying out two-band photometry in wide fields with a constellation of six (presently, three operational) BRIght Target Explorer (BRITE) nanosatellites. The mission was built by a consortium of three countries, Canada, Austria, and Poland, each operating two BRITE satellites. The six satellites were launched into low-Earth orbits between February 2013 and August 2014. Each satellite is a cube-shaped spacecraft with sides of hosting an optical telescope of aperture feeding an uncooled CCD with a field of view of approximately 20° × 24°. The satellites were intended for photometry of the brightest stars in single passband located in the blue (three satellites) or red (the other three satellites) part of the optical range. Early history The idea of using microsatellite for scientific observations, especially for photometry of bright stars, was born during discussions on possible designs for Canada's first scientific satellite.

Atmospheric Reentry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MaSat-1
MaSat-1 (from the words ''Magyar'' and ''Satellite'', the first meaning " Hungarian" in Hungarian, ''maszat'', pronounced IPA ˆmÉ’sÉ’t meaning "smudge") is the first indigenous Hungarian satellite, developed and built by students at the Technical University of Budapest.
