Aerogels made of cadmium selenide quantum dots in a porous 3-D network have been developed for use in the semiconductor industry. [73] Aerogel performance may be augmented for a specific application by the addition of dopants, reinforcing structures, and hybridizing compounds. For example, Spaceloft is a composite of aerogel with some kind of ...
A particle captured in aerogel. Aerogel is a silica-based porous solid with a sponge-like structure, 99.8% of whose volume is empty space. Aerogel has about 1/1000 of the density of glass. An aerogel was used in the Stardust spacecraft because the dust particles the spacecraft was to collect would have an impact speed of about 6 km/s. A ...
The Japanese Kibo module (left) and the Exposed Facility Unit (right). The Tanpopo mission is an orbital astrobiology experiment investigating the potential interplanetary transfer of life, organic compounds, and possible terrestrial particles in the low Earth orbit.
Either way, in 1931 Kistler published a paper in Nature (vol. 127, p. 741) titled "Coherent Expanded Aerogels and Jellies". He left his teaching post at the University of Illinois in 1935 and signed a contract with Monsanto Company in the early 1940s to start developing granular silica aerogel products under the trademark Santocel. Largely used ...
Stardust was a 385-kilogram robotic space probe launched by NASA on 7 February 1999. Its primary mission was to collect dust samples from the coma of comet Wild 2, as well as samples of cosmic dust, and return them to Earth for analysis.
Genesis was a Discovery-class mission of the NASA Jet Propulsion Laboratory (JPL) at the California Institute of Technology. The spacecraft was designed and built by Lockheed Martin Space Systems at a total mission cost of US$264 million. NASA launched the craft on a Delta II 7326 rocket on August 8, 2001, at 16:13:40 UTC from Cape Canaveral.
Other ground and space-based telescopes were used for follow-up observations of the newly discovered object, including the MeerKAT radio telescope in South Africa and the XMM-Newton space ...
Dust collector with aerogel blocks as used by the Stardust and Tanpopo missions. Examples of extraterrestrial material collected on Earth include cosmic dust and meteorites. Some of the meteorites found on Earth had their origin in another Solar System object such as the Moon, [1] Martian meteorites, [2] [3] and the HED meteorite from Vesta.
