Dynamic science on the Stardust mission

چکیده
[1] Radio Doppler and ranging data at X band ( 8.4 GHz), optical navigation data, and spacecraft attitude control data can be used to characterize the dust environment surrounding comet 81P/Wild 2 and possibly the mass and bulk density of its nucleus. As a secondary objective, a favorable solar conjunction prior to the cometary encounter on 2 January 2004 can be used to sound the Sun’s corona at X band.

متن کاملNASA returns rocks from a comet.
Cometary particles returned by the Stardust Discovery Mission are primarily silicate materials of solar system origin. Some of the grains were formed at high temperatures close to the Sun, but then transported far out to the Kuiper belt region of the solar system before being incorporated in the comet.
متن کاملThe Comet Coma Rendezvous Sample Return (CCRSR) Mission Concept – The Next Step Beyond Stardust
The Stardust Comet Sample Return Mission successfully returned particles from the coma of Comet 81P/Wild 2, providing a host of important new insights into the nature of cometary materials and the processes which formed our Solar System. These samples have important limitations, however, because they were collected in modest numbers at harsh hypervelocities and represent a one-time random sampl...
متن کاملUnderstanding the Comet Wild 2 Mineralogy in Samples from the Stardust Mission
The status of the solid materials and mineralogical and petrological results of the Stardust mission to comet 81P/Wild 2 are presented. This mission became the first successful samplereturn mission since the Apollo project. This time the challenges were much less related to the availability of state-of-the-art analytical capabilities. Still, dedicated tools had to be developed to manipulate the...
متن کاملNM-SCALE ANATOMY OF AN ENTIRE STARDUST CARROT TRACK. K.Nakamura-Messenger
Introduction: Comet Wild-2 samples collected by NASA's Stardust mission are extremely complex, heterogeneous , and have experienced wide ranges of alteration during the capture process. There are two major types of track morphologies: " carrot " and " bulbous , " that reflect different structural/compositional properties of the impactors. Carrot type tracks are typically produced by compact or ...
