Cosmic Dust Analyzer
The Cosmic Dust Analyzer (CDA) on the Cassini mission is a large-area (0.1 m2 total sensitive area) multi-sensor dust instrument that includes a chemical dust analyzer (time-of-flight mass spectrometer), a highly reliable impact ionization detector, and two high rate polarized polyvinylidene fluoride (PVDF) detectors. During 6 years en route to Saturn the CDA analysed the interplanetary dust cloud, the stream of interstellar dust, and Jupiter dust streams. During 13 years in orbit around Saturn the CDA studied the E ring, dust in the plumes of Enceladus, and dust in Saturn's environment. Overview The Cosmic Dust Analyzer, CDA was the seventh dust instrument from the Max Planck Institute for Nuclear Physics (MPIK), Heidelberg (Germany) following the dust detectors on the HEOS 2 sat5ellite and dust detctors on the Galileo and Ulysses space probes and the more complex dust analyzers on the Helios spacecraft, the Giotto and VeGa spacecraft to Halley's Comet. The new dust analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo And Ulysses Dust Detectors
The Galileo and Ulysses Dust Detectors are almost identical dust instruments on the Galileo and Ulysses missions. The instruments are large-area (0.1 m2 sensitive area) highly reliable impact ionization detectors of sub-micron and micron sized dust particles. With these instruments the interplanetary dust cloud was characterized between Venus’ and Jupiter's orbits and over the solar poles. A stream of interstellar dust passing through the planetary system was discovered. Close to and inside the Jupiter system streams nanometer sized dust particles that were emitted from volcanoes on Jupiter's moon Io and ejecta clouds around the Galilean moons were discovered and characterized. Overview Following the first dust instruments from the Max Planck Institute for Nuclear Physics (MPIK), Heidelberg (Germany) on the HEOS 2 satellite and the Helios spacecraft a new dust instrument was developed by a Team of Scientists and Engineers of Eberhard Grün to detect cosmic dust ...

Doktoringenieur
The Doktoringenieur (acronym Dr.-Ing., also ''Doktor der Ingenieurwissenschaften'') is the German engineering doctorate degree, comparable to the Doctor of Engineering, Engineering Doctorate, Doctor of Science (Engineering), Doctor of Science (Technology) or a PhD in Engineering or Architecture. It was first introduced in 1899, in the context of the centenary of the Technical University of Berlin, at the Prussian Institutes of Technology. The other German states adopted it in the following years. In contrast to the other historic doctoral degrees (e.g. ''Dr. phil.'', ''Dr. iur.'' or ''Dr. med.''), the Doktoringenieur was not titled in Latin but German, and therefore written with dash (Dr.-Ing.). In the field of mathematics, computer science and natural sciences, some universities offer the choice between ''Dr.-Ing.'' and ''Dr. rer. nat.'' based on the primary focus of the dissertation. If the contributions focus slightly more on applied scientific engineering a ''Dr.-Ing.'' is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rutherford Appleton Laboratory
The Rutherford Appleton Laboratory (RAL) is one of the national scientific research laboratories in the UK operated by the Science and Technology Facilities Council (STFC). It began as the Rutherford High Energy Laboratory, merged with the Atlas Computer Laboratory in 1975 to create the Rutherford Lab; then in 1979 with the Appleton Laboratory to form the current laboratory. It is located on the Harwell Science and Innovation Campus at Chilton near Didcot in Oxfordshire, United Kingdom. It has a staff of approximately 1,200 people who support the work of over 10,000 scientists and engineers, chiefly from the university research community. The laboratory's programme is designed to deliver trained manpower and economic growth for the UK as the result of achievements in science.

Halley's Comet
Halley's Comet or Comet Halley, officially designated 1P/Halley, is a List of periodic comets, short-period comet visible from Earth every 75–79 years. Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and thus the only naked-eye comet that can appear twice in a human lifetime. Halley last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC. But it was not until 1705 that the English astronomer Edmond Halley understood that these appearances were reappearances of the same comet. As a result of this discovery, the comet is named after Halley. During its 1986 visit to the inner Solar System, Halley's Comet became the first comet to be observed in detail by spacecraft, providing the first observational data on the structure of a comet nucleus and the mecha ...
