Probe may have found cosmic dust, BBC

"The discovery was made by a member of the public, using the Stardust@Home internet application, which invited participants to search the aerogel collection medium for tiny particles of the dust. "There are two particles, but they are in the same track. So when they hit the aerogel, they were together - they are two components of the same particle," Dr Westphal told BBC News. "But they are very different from each other. That in itself is interesting, because if this does turn out to be interstellar dust, then it is a bit more heterogeneous than people thought." The initial speck, known as particle 30, was spotted by Bruce Hudson, from Ontario in Canada. Under the agreement made between the science team and participants in Stardust@Home, Mr Hudson was allowed to choose a name for the particle; he called it Orion."

In previous work, two platforms have been developed for testing computer-vision algorithms for robotic planetary exploration (McGuire et al. 2004b,2005; Bartolo et al. 2007). The wearable-computer platform has been tested at geological and astrobiological field sites in Spain (Rivas Vaciamadrid and Riba de Santiuste), and the phone-camera has been tested at a geological field site in Malta.

In this work, we (i) apply a Hopfield neural-network algorithm for novelty detection based upon color, (ii) integrate a field-capable digital microscope on the wearable computer platform, (iii) test this novelty detection with the digital microscope at Rivas Vaciamadrid, (iv) develop a Bluetooth communication mode for the phone-camera platform, in order to allow access to a mobile processing computer at the field sites, and (v) test the novelty detection on the Bluetooth-enabled phone-camera connected to a netbook computer at the Mars Desert Research Station in Utah.
