Join us for a Deep Dive into Double Asteroid Redirection Test (DART) - NASA's First Planetary Defense Test Mission. 

DART is the first-ever space mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid's motion in space through kinetic impact.  Launched in 2021, DART will be kinetically impacting Dimorphos - a known asteroid (with no threat to Earth) on September 26 at 7:14 pm ET. 

DART is the world’s first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards.  The goal is to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes.  DART will show that a spacecraft can autonomously navigate to a target asteroid and intentionally collide with the asteroid – a method of deflection called kinetic impact. The test will provide important data to help better prepare for an asteroid that might pose an impact hazard to Earth, should one ever be discovered.

LICIACube, a CubeSat riding with DART provided by the Italian Space Agency (ASI), will be released prior to DART’s impact to capture images of the impact and the resulting cloud of ejected matter.  Researchers will precisely measure that change using telescopes on Earth. Their results will validate and improve scientific computer models critical to predicting the effectiveness of the kinetic impact as a reliable method for asteroid deflection. Roughly four years after DART’s impact, ESA’s (European Space Agency) Hera project will conduct detailed surveys of both asteroids, with particular focus on the crater left by DART’s collision and a precise determination of Dimorphos’ mass.

“DART is turning science fiction into science fact and is a testament to NASA’s proactivity and innovation for the benefit of all,” said NASA Administrator Bill Nelson. “In addition to all the ways NASA studies our universe and our home planet, we’re also working to protect that home, and this test will help prove out one viable way to protect our planet from a hazardous asteroid should one ever be discovered that is headed toward Earth.”

Her research interest include the impact of technology on student achievement and teacher behavior. Buckner recently served as a 2013-14 Einstein Fellow at the National Science Foundation Education and Human Resources Directorate where she collaborated with colleagues on learning, learning environments, broadening participating and workforce development. Barbie sees education as her calling and has spent her life sharing her love for learning with everyone around her. Knowing that today’s student will compete in a global economy, Barbie says that “It is imperative that today’s students are prepared with consistent, rigorous, and relevant standards that encourage more STEM majors, particularly women, to keep this great nation at the forefront in technology, innovation, and advancement.”
