In May last year two University of Arizona undergrads were awarded NASA Institute for Advanced Concepts (NIAC) Student Fellows Prizes -- Rigel Woida (left) in regard to Mars terraforming, and engineering physics major and cosmochemistry student Daniella Della-Giustina about using near-Earth asteroids as radiation shielding for human travel to Mars -- examples of NIAC's futuristic work that is now being closed down.

Impact Risk Monitoring  on 3 July '07

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2354 UTC)
See the CRT page for a list of all objects rated as risks in the last 30 days.
Note that the time horizon for JPL is 100 years from today and for NEODyS is usually the year 2080.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON (backup) risk pages.

Notes for Today's Latest Risk Assessments
2007 LQ19JPL2204208211.8e-06-2.39-2.391JPL: "Analysis based on 18 observations spanning 19.042 days (2007-Jun-13.78733 to 2007-Jul-02.82941)." Diameter approximately 0.930 km. from mean, weighted H=17.8.
NEODyS1350208212.1e-06-2.34-2.341NEODyS: "Based on 18 optical observations (of which 0 are rejected as outliers) from 2007/06/13.788 to 2007/07/02.830. NOTE: The Virtual Impactor in 2082/07/11.625 in the table above is rated as Torino Scale 1."

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an 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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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" for more about this.
