SPEX (astronomy)
The SPEX (Spectropolarimeter for Planetary Exploration) is a single-channel, high-precision polarimeter for the characterization of planetary atmospheres. It is intended for planetary science missions, but it could, with minor modifications, also be used for Earth observation by a microsatellite A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's genome. ..., such as the Dutch FAST-D project.

Planetary Science
Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, which originally grew from astronomy and Earth science, and now incorporates many disciplines, including planetary geology, cosmochemistry, atmospheric science, physics, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve combinations of spac ...

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 ...

Netherlands Institute For Space Research
SRON Netherlands Institute for Space Research is the Dutch expertise institute for space research. The Institute develops and uses innovative technology for research in space, focusing on astrophysical research, Earth science and planetary research. SRON has a line of research into new and more sensitive sensors for X-rays and infrared radiation. SRON was founded in 1983 under the name ''Stichting Ruimteonderzoek Nederland'' or ''Space Research Organisation, Netherlands''. SRON is a member institution of the Dutch Research Council (NWO). The Institute is headquartered in Leiden with additional facilities in the city of Groningen. Science and technology The institute has over 250 staff members who are employed in a support department and five divisions: High-Energy Astrophysics (HEA), Low-Energy Astrophysics (LEA), Earth and Planetary Science (EPS), Sensor Research and Technology (SR&T) and Engineering Division (ED). Technology SRON's ambition is to act as a leading institute i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
