The spacecraft NASA deliberately crashed into an asteroid last month succeeded in nudging the rocky moonlet from its natural path into a faster orbit, marking the first time humanity has altered the motion of a celestial body, the US space agency announced, Report informs, citing Reuters.
The $330 million proof-of-concept mission, which was seven years in development, also represented the world's first test of a planetary defense system designed to prevent a potential doomsday meteorite collision with Earth.
Findings of telescope observations unveiled at a NASA news briefing in Washington confirmed the suicide test flight of the DART spacecraft on Sept. 26 achieved its primary objective: changing the direction of an asteroid through sheer kinetic force.
Astronomical measurements over the past two weeks showed the target asteroid was bumped slightly closer to the larger parent asteroid it orbits and that its orbital period was shortened by 32 minutes, NASA scientists said.
