Surface of Young Jupiter Family Comet 81P/Wild 2: View from the Stardust Spacecraft

D. E. Brownlee
2004 Science  
Green 4 We interpret the nucleus properties and jet activity from the Stardust spacecraft imaging and the onboard dust monitoring system data.  ...  The surface is active and yet it retains ancient terrain. Wild 2 appears to be in the early stages of its degradation phase as a small volatile-rich body in the inner solar system.  ...

Curation, spacecraft recovery, and preliminary examination for the Stardust mission: A perspective from the curatorial facility

Michael Zolensky, Keiko Nakamura-Messenger, Lisa Fletcher, Thomas See
2008 Meteoritics and Planetary Science  
The Curation office played a role in the mission from its inception, most critically assisting in the design and implementation of the spacecraft contamination control plan, and in planning and documenting  ...  A unique class 100 cleanroom was built to maintain the returned comet and interstellar samples in clean comfort, and to permit dissection and allocation of samples for analysis.  ...  Because the samples are both microscopic and fragile, and distributed along impact tracks ranging from tens of micrometers to millimeters in size, it has proven to be a significant challenge to reliably  ...
