CU-Boulder and the New Horizons Pluto/Kuiper Belt mission announced this week that the school's Lab for Atmospheric and Space Physics' (LASP) Student Dust Counter (SDC) is not only "the first student-built and -operated science instrument ever sent on a planetary space mission," but at 18 AU also "now holds the record for the most distant working dust detector" (data viewer).

Impact Risk Monitoring  on 13 October '10

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2311 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
