Joy! NASA’s asteroid mission achieved mission impossible, created history

NASA asteroid mission has done something considered impossible and the world can sleep easier now. NASA’s Double Asteroid Redirection Test, also known as DART, has successfully managed to deflect a massive asteroid from its path after crashing its 570kg spacecraft into asteroid Dimorphos.

NASA chief Bill Nelson said, “All of us have a responsibility to protect our home planet. After all, it’s the only one we have. This mission shows that NASA is trying to be ready for whatever the universe throws at us.” He added that the US agency has proven that it can defend the planet. (via REUTERS)

Before the crash, asteroid Dimorphous took about 11 hours and 55 minutes to orbit the larger asteroid Didymos, whereas, post crash, it took only 11 hours and 23 minutes to orbit the larger asteroid. (via REUTERS)

DART impact has shortened the orbit by 32 minutes. None of these space rocks - Dimorphous as well as Didymos pose any threat to our planet, hence it was an ideal target to carry out the DART mission. At the time of collision, the DART spacecraft was traveling at 14000 (22,530-kmph) miles per hour. (via REUTERS)

The DART team is currently measuring how efficiently the spacecraft transferred its momentum to the asteroid. “DART has given us some fascinating data about both asteroid properties and the effectiveness of a kinetic impactor as a planetary defense technology. The DART team is continuing to work on this rich dataset to fully understand this first planetary defense test of asteroid deflection,” said Nancy Chabot, the DART coordination lead at the Johns Hopkins Applied Physics Laboratory in a press statement.
