Anyway, near the end of this episode (season 1 episode 3 I think), they were speaking to a meteorite expert about the fact that sometimes meteorites completely disintegrates before reaching the planet's surface.
I recognized the expert right away; it was Mike Zolensky who is pictured in the latest blog post when they were gathering samples from the Stardust return capsule. I noticed that he was wearing a Stardust polo shirt during this interview and I thought this was really cool!
I wish that I could buy one of those Stardust shirts somewhere but was unable to find one, however I did find several different 'Stardust NeXT' shirts on the Caltech store page. I might actually buy one of those.
