☆ NASA's asteroid-deflecting DART spacecraft nears planned impact with its target

NASA/Johns Hopkins/Handout via REUTERSSept 26 (Reuters) - Ten months after launch, NASA's asteroid-deflecting DART spacecraft neared a planned impact with its target on Monday in a test of the world's first planetary defense system, designed to prevent a doomsday collision with Earth. Neither object presents any actual threat to Earth, and NASA scientists said their DART test cannot create a new existential hazard by mistake. Also, their relative proximity to Earth and dual-asteroid configuration make them ideal for the first proof-of-concept mission of DART, short for Double Asteroid Redirection Test. ROBOTIC SUICIDE MISSIONThe mission represents a rare instance in which a NASA spacecraft must ultimately crash to succeed.

☆ NASA spacecraft closes in on asteroid for head-on collision

A NASA spacecraft closed in on an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth. The galactic grand slam was set to occur at a harmless asteroid 7 million miles (9.6 million kilometers) away, with the spacecraft named Dart plowing into the rock at 14,000 mph (22,500 kph). The $325 million mission is the first attempt to shift the position of an asteroid or any other natural object in space. The spacecraft packed a scant 1,260 pounds (570 kilograms), compared with the asteroid's 11 billion pounds (5 billion kilograms). Monday's dramatic action aside, the world must do a better job of identifying the countless space rocks lurking out there, warned the foundation's executive director, Ed Lu, a former astronaut.
☆ NASA crashes DART spacecraft into an asteroid, testing a tactic to bump space rocks away from Earth

NASA's 1,376-pound probe traveled about 6.8 million miles before crashing into the asteroid, as part of the Double Asteroid Redirection Test (DART) mission. Scientists will be monitoring the trajectory of the asteroid, Dimorphos, which orbits a larger asteroid, Didymos. As the DART spacecraft flew closer, Dimorphos emerged as a separate point of light that grew larger and brighter.

The DART mission operations team at the Johns Hopkins Applied Physics Laboratory erupted in applause after the probe's successful demise.
☆ NASA is about to crash a spacecraft into an asteroid. Here's why the mission could one day save humanity.

The mission, known as DART, or the Double Asteroid Redirection Test, will attempt a method of planetary defense that could save Earth from an asteroid on a potential collision course with the planet. On Monday, the spacecraft will crash into Dimorphos at a blistering speed of around 4 miles per second, or 15,000 mph. Ground-based telescopes will be used to time Dimorphos' orbit and determine whether the mission was a success. The Applied Physics Lab built and manages the $325 million DART mission for NASA. Even if the DART mission fails, scientists will learn a lot from the experiment, said Andrea Riley, a program executive in NASA's Planetary Defense Coordination Office.

NASA's Double Asteroid Redirection Test will collide with an asteroid on September 26. NASA's Double Asteroid Redirection Test (DART) mission launched atop a SpaceX Falcon 9 in November 2021, with the aim of nudging a space rock into a slightly tighter orbit around its companion asteroid. The $308 million spacecraft traveled 6.8 million miles from Earth to Dimorphos, a small asteroid orbiting the asteroid Didymos. NASA JPL DART Navigation TeamOn Monday, September 26, four hours before impact, DART will switch into autonomous mode, steering itself toward its target.
