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.

The truck, spacecraft and a small motorcade of APL engineers and technicians pulled into Vandenberg Space Force Base near Lompoc, California, on Saturday, Oct. 2, in the early afternoon local time.

"Although it was just a few days of travel, this has been a journey long coming," said Elena Adams, DART mission systems engineer from APL. "We are all excited and relieved to see the truck arrive safely at Vandenberg and for DART to begin its final preparations for launch."

The spacecraft will go through a series of final tests and checks, as well as fueling, in the next few weeks as the team prepares for DART's scheduled launch aboard a SpaceX Falcon 9 rocket in late November.

In mid-September, the spacecraft successfully went through a pre-shipment review to ensure each part was complete and ready for shipment. The DART team also successfully went through a flight operational readiness review to assess its readiness to start spacecraft operations once DART enters space.

"We spent the last one and a half years testing DART on the ground, practicing for what's the most highly anticipated part yet: its flight to Dimorphos," Adams said. "We have a few more mission rehearsals to do, with the team practicing spacecraft launch operations from Vandenberg in California and the APL Mission Operations Center in Maryland. Once completed, we will be ready for launch and operations."

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.

Although neither asteroid poses a threat to Earth, the collision with Dimorphos enables researchers to demonstrate the deflection technique along with several new technologies, and collect important data to enhance our modeling and predictive capabilities for asteroid deflection. Those enhancements will help us better prepare should an asteroid ever be discovered as a threat to Earth.

Highly porous rocks responsible for Bennu's surprisingly craggy surface
Tucson AZ (SPX) Oct 18, 2021
Scientists thought asteroid Bennu's surface would be like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth's orbit had suggested the presence of ��large swaths of fine-grain material called fine regolith that's smaller than a few centimeters. But when the spacecraft of NASA's University of Arizona-led OSIRIS-REx asteroid sample return mission arrived at Bennu in late 2018, the mission team saw a surface c ... read more
