NASA’s Test Crash Into Asteroid Was 25X More Successful Than Benchmark Objective | Eastern North Carolina Now | NASA announced Tuesday that according to data it obtained from a recent test in which the agency intentionally crashed a spacecraft into an asteroid, it was successful in altering the motion of the asteroid, the first time a mankind has altered the motion of a celestial object.

    NASA announced Tuesday that according to data it obtained from a recent test in which the agency intentionally crashed a spacecraft into an asteroid, it was successful in altering the motion of the asteroid, the first time a mankind has altered the motion of a celestial object.

    The results from NASA's Double Asteroid Redirection Test (DART) investigation were an important development from a defense perspective because the test was part of NASA's creation of asteroid deflection technology that could be used to protect earth one day.

    In a statement, NASA explained what the mission was, the metrics that were used to define a successful mission, and the results:

    Prior to DART's impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid, Didymos. Since DART's intentional collision with Dimorphos on Sept. 26, astronomers have been using telescopes on Earth to measure how much that time has changed. Now, the investigation team has confirmed the spacecraft's impact altered Dimorphos' orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.

    Before its encounter, NASA had defined a minimum successful orbit period change of Dimorphos as change of 73 seconds or more. This early data show DART surpassed this minimum benchmark by more than 25 times.


    "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."

    Lori Glaze, director of NASA's Planetary Science Division at NASA Headquarters in Washington, said that the result was an important step in understanding how asteroid deflection technology could be used in the future.

    "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," she said.

    "DART has given us some fascinating data about both asteroid properties and the effectiveness of a kinetic impactor as a planetary defense technology," said Nancy Chabot, the DART coordination lead from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. "The DART team is continuing to work on this rich dataset to fully understand this first planetary defense test of asteroid deflection."
