GC016 Stardust: Return to Sender (part 1)

On the 15th of January, a special package was delivered to a dry lake bed in Utah -- and nobody complained that it took 7 years to arrive and covered 3 billion miles in the meantime. This particular package cost $212M to produce, but its contents are (at least in scientific terms) priceless. This week's episode is a discussion of the Stardust mission, and its (political and technical) history.
