English: Just two days after leaving the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, in a specialized container carefully strapped to the deck of a semi-trailer truck, NASA’s Double Asteroid Redirection Test (DART) spacecraft arrived in California — its final stop here on Earth.

DART will be the world’s first mission to test planetary defense techniques, demonstrating one mitigation method of asteroid deflection, called kinetic impact. DART will impact the small asteroid moonlet Dimorphos, which orbits a larger companion, Didymos, in a binary asteroid system to change its orbital period.

Inside a cleanroom at Johns Hopkins APL, the DART spacecraft being moved into a specialized shipping container that headed across the country to Vandenberg Space Force Base near Lompoc, California, where DART is scheduled to launch from late next month.
