In this framework, the control law can be computed using deterministic algorithms. Summary: The classic approach in Automatic Control relies on the use of simplified models of the systems and reformulations of the specifications.

The primary objective of the Stardust mission is to capture both cometary samples and interstellar dust. Scientists have found a wide range of compositions and structures for the comet Wild 2 particles that were captured and returned to Earth by NASA's Stardust spacecraft. Stardust Findings Suggest Comets More Complex Than ThoughtĬomets may be more than just simple conglomerations of ice, dust and gases. NASA Study Finds New Kind of Organics in Stardust MissionĪ team of scientists found a new class of organics in comet dust captured from comet Wild 2 in 2004 by NASA's Stardust spacecraft. They do contain some stardust grains from other stars but the majority of solids are solar system materials that appear to have formed over a very broad range of solar distances and perhaps over an extended time range. The comet particles returned by the Stardust mission have been a real bonanza.
The Cosmic Dust Lab (CDL)Īt Johnson Space Center in Houston, Texas, will be closed down and cleaned in order to resume work associated with processing of the Interstellar Tray from Stardust. The 2007 round of sample processing and allocations of Cosmic Dust has been completed. The capsule will go on public display in the museum's Of flight icons in the Smithsonian's National Air and Space Museum in Stardust sample return capsule will join the collection Stardust Capsule To Go On Display At Smithsonian Life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. NASA scientists have discovered glycine, a fundamental building block of The Stardust-NExT will utilize the existing Stardust spacecraft to flyby Comet Tempel 1 in 2011, and observe changes in theĬomet since Deep Impact visited it in 2005.įirst Discovery of Life's Building Block in Comet When the international team of 200 scientists began examination of the returned particles, we found that the particles were indeed ancient building blocks of the solar system but the nature and origin of the particles was quite unexpected. They were expected to contain materials that the solar system formed from, preserved in ice for billions of years. Comets are ancient bodies of frozen ice and dust that formed beyond the orbit of the most distant planet. The primary goal of the Stardust mission was to collect samples of a comet and return them to Earth for laboratory analysis.
