On 14 February 2026, at the American Association for the Advancement of Science annual meeting in Phoenix, Arizona, Kelly Fast presented data on a persistent gap in planetary defense capabilities.

A study found that these cosmic bodies appear to hold up remarkably well to sudden energy deposition and shock conditions, so we may be able to knock them off course and avoid disaster.
