GREENBELT, Md. (NASA PR) — Although the chance of an asteroid impacting Earth is small, even a relatively small asteroid of about 500 feet (about 150 meters) across carries enough energy to cause widespread damage around the impact site. NASA leads efforts in the U.S. and worldwide both to detect and track potentially hazardous asteroids and to study technologies to mitigate or avoid impacts on Earth. If an asteroid were discovered and determined to be on a collision course with Earth, one response could be to launch a “kinetic impactor” – a high-velocity spacecraft that would deflect the asteroid by ramming into it, altering the asteroid’s orbit slightly so that it misses Earth. NASA’s Double Asteroid Redirection Test (DART) will be the first mission to demonstrate asteroid deflection using a kinetic impactor.

MADRID (Spanish Astrobiology Center) — Currently the Astrobiology Center (CAB, CSIC-INTA) is an integral part of the joint space mission of NASA and ESA called DART-Hera. Its objective consists of sending two spacecraft to a binary asteroid system known as Didymos 65803 and thus validating the impact techniques in order to avoid future collisions with potentially dangerous asteroids for our planet.

PARIS (ESA PR) — The world will be watching the milestone launch of NASA’s Double Asteroid Redirection Test, DART, spacecraft on Wednesday, 24 November, intended to alter one small part of the Solar System forever.

DART will collide with the small moon of an asteroid in order to shift its orbit around its parent body – to test the concept of diverting threatening objects away from Earth.

VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — NASA’s Double Asteroid Redirection Test (DART), the world’s first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards, launched Wednesday at 1:21 a.m. EST on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.

Just one part of NASA’s larger planetary defense strategy, DART – built and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland – will impact a known asteroid that is not a threat to Earth. Its goal is to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes.

It sounds like a plot for a movie but protecting Earth from a potential impact by a hazardous asteroid is the objective of an upcoming NASA mission.

The Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of technologies for mitigating such a threat. DART’s target asteroid is not a threat to Earth. The DART spacecraft launch window opens Nov. 24. It will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California.

VANDENBERG SPACE FORCE BASE, Calif. (NASA PR) — 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.

NASA’s First Planetary Defense Mission Target Gets a New Name

LAUREL, Md. (NASA PR) — Nearly two decades ago, a near-Earth asteroid was discovered to have a moon and the binary system was given the name “Didymos”—Greek for “twin,” a loose description of the larger main body and the smaller orbiting moon, which became unofficially known as Didymos B. 

In 2022, that moon will be the target of NASA’s Double Asteroid Redirection Test (DART), the first full-scale demonstration of an asteroid deflection technology for planetary defense. The DART spacecraft will execute a kinetic impact, deliberately crashing into the asteroid to change its motion in space. To mark this historic mission, Didymos B is getting an official name of its own: Dimorphos.
