Hubble's time-lapse movie of the aftermath of DART's collision reveals surprising and remarkable, hour-by-hour changes
National Aeronautics and Space Administration's (NASA's) Hubble Space Telescope captured a series of photos of asteroid Dimorphos when it was deliberately hit by a 1,200-pound NASA spacecraft called DART on September 26, 2022, according to their statement.
Hubble's time-lapse movie of the aftermath of DART's collision reveals surprising and remarkable, hour-by-hour changes as dust and chunks of debris were flung into space, NASA said in their statement.
Smashing head on into the asteroid at 13,000 miles per hour, the DART impactor blasted over 1,000 tons of dust and rock off of the asteroid.
The Hubble movie offers invaluable new clues into how the debris was dispersed into a complex pattern in the days following the impact, NASA said.
This was over a volume of space much larger than could be recorded by the LICIACube cubesat, which flew past the binary asteroid minutes after DART's impact, they said.
The primary objective of DART, which stands for Double Asteroid Redirection Test, was to test our ability to alter the asteroid's trajectory as it orbits its larger companion asteroid, Didymos, the agency said.
Though neither Didymos nor Dimorphos poses any threat to Earth, data from the mission will help inform researchers how to potentially divert an asteroid's path away from Earth, if ever necessary, the statement said.

On December 7, 1909, Belgian-American chemist Leo Baekeland’s process patent for making Bakelite was granted, two years after he had figured it out. Bakelite is the first fully synthetic plastic and its invention marked the beginning of the Age of Plastics. A.S.Ganesh tells you more about Baekeland and his Bakelite…
