NASA’sDART missionto ram a kinetic impactor into a harmless asteroid wentperfectlyyesterday , result in the desired destruction of the ballistic capsule . And as purview from Earth showed , the effect of the impact were n’t subtle .
The 1,340 - pound spacecraft plowed into Dimorphos , a small moon around asteroid Didymos , at 7:14 p.m. ET on Monday , following a 10 - month journeying to the binary asteroid system . DART ’s onboard genus Draco camera trance stunning POV images as it sped toward the asteroid at speeds reaching 14,000 nautical mile per hour ( 22,500 kilometers per time of day ) .
TheDRACO imagesof the football stadium - sizing Dimorphos were sublime , revealing a mountainous surface covered in boulders , rocks , and dust . DART was obliterated as a result of the wallop , requiring other instruments to chronicle the aftermath . scientist are now working to determine the academic degree to which DART impress the moonlet ’s speed and actuate a potential variety in its orbital trajectory around its prominent host , Didymos . A meaningful solvent would suggest that scientists have stumbled upon apotential way to deflect hazardous asteroids . Dimorphos and Didymos do n’t pose a menace to our major planet , neither before nor after the DART experimentation — this was merely a psychometric test to see if we can successfully move a infinite rock .

telescope around the world were focused on the binary asteroid arrangement . depart into the experiment , it was n’t unclouded how visible the impact might be from Earth , but the images we ’re see from the ground clearly show a substantial feather emanating from Didymos .
“ It is hard to comment on the sensational experience we had last night , ” wrote the Virtual Telescope task in ablog post . “ We check in veridical - time , with our very own eye , the event of DART slamming into its mark asteroid Didymos , make it much hopeful , with a Brobdingnagian cloud of junk . ” To track the impact , the Italy - based Virtual Telescope Project collaborate with the Klein Karoo Observatory in Calitzdorp , South Africa . “ The quarry asteroid is visible on the bottom right of each prototype and clearly spring up a dusty cloud , which expands quite rapidly in [ an easterly ] way , where the asteroid was move , to , ” agree to the post . The astronomers estimate that detritus swarm was expanding at a rate of 1.8 nautical mile per second ( 2.9 kilometre / s ) .
Astronomers with the ATLAS undertaking also chronicled the event . brusk for Asteroid Terrestrial - wallop Last Alert System , ATLAS is an asteroid impact early warning system base in Hawaii and funded by NASA . “ ATLAS observation of the DART spacecraft at Didymos ! ” outcry ATLAS in atweet . A zip - up timelapse testify a large plume acquire by the impact and prompt in the direction of the binary asteroid system .

The South African Astronomical Observatory , which manages an observatory in Sutherland , South Africa , captured a similartimelapse . Again , it prove a growing plume moving in the direction of the asteroid . It ’s authoritative to place out that , at a distance of over 6.8 million miles ( 11 million km ) , the binary dyad come along as a single object .

I ’m struck by the size of the feather , but it ’s difficult to tell if the encroachment kicked up a lot of material or if these views are a function of really bright junk . Views of Dimorphos ’s surface looked very rubble mound - like , evoke a loose conglomeration of materials . If that ’s the casing , Dimorphos may have done wonderful equipment casualty to the asteroid , but we need more data point to be sure . At the very least , DART produced a substantial cloud of detritus .
As to when we ’ll fuck the stage to which Dimorphos ’s orbital trajectory was change , that could take anywhere from several sidereal day to several weeks . disregardless , it ’ll be a fascinating result .
