NASA’s Double Asteroid Redirection Test (DART) command team at Johns Hopkins University, Applied Physics Laboratory monitoring the DART spacecraft’s impact into the asteroid Dimorphos. The operation is the first of its kind test to redirect deadly asteroids from hitting Earth.

WASHINGTON, D.C. — NASA confirmed this week that they successfully changed the course of an asteroid.  

The project, called D.A.R.T (Double Asteroid Redirection Test), changed the course trajectory of the asteroid Dimorphos.  

On September 26, NASA crashed a spacecraft into the asteroid’s surface, causing its orbit around the larger Didymos asteroid to shorten by 32 minutes.  

NASA officials deemed the mission a success.  

Technicians prepare to move NASA’s Double Asteroid Redirection Test (DART) spacecraft onto a work stand inside the Astrotech Space Operations Facility at Vandenberg Space Force Base in California following its arrival at the facility on Oct. 4, 2021. Once secured on its stand, the spacecraft will undergo a series of tests and checkouts to confirm it is ready for launch. DART is the first mission to test technologies for preventing an impact of Earth by a hazardous asteroid. The mission is targeted to launch on Nov. 23, 2021, aboard a SpaceX Falcon 9 rocket from Vandenberg. NASA’s Launch Services Program, based at Kennedy Space Center, America’s multi-user spaceport, is managing the launch.

“All of us have a responsibility to protect our home planet. After all, it’s the only one we have,” said NASA Administrator Bill Nelson. “This mission shows that NASA is trying to be ready for whatever the universe throws at us. NASA has proven we are serious as a defender of the planet. This is a watershed moment for planetary defense and all of humanity, demonstrating commitment from NASA’s exceptional team and partners from around the world.” 

This project is the first undertaking in human history to change the course of a celestial object.  

“This result is one important step toward understanding the full effect of DART’s impact with its target asteroid,” said Lori Glaze, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “As new data come in each day, astronomers will be able to better assess whether, and how, a mission like DART could be used in the future to help protect Earth from a collision with an asteroid if we ever discover one headed our way.”
