Hayabusa re-entry over Australia. 
Credit Clay Center Obs./NASA.

The Japanese Hayabusa asteroid sample return mission arrived late yesterday evening over Woomera, Australia (1351 UTC). Its small re-entry capsule is the bright point at lower right while the trailing larger spacecraft destructs, hitting the atmosphere at the superorbital speed of natural meteors. Image by staff and students of the Clay Center Observatory aboard a NASA aircraft, posted by NASA/Ames' observing campaign. BBC has a report today on the successful capsule recovery, and [new] also see this. Read more from earlier here and here.

Impact Risk Monitoring  on 14 June '10

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2358 and JPL at 2359 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
