NASA’s DART Spacecraft Strikes an Asteroid—on Purpose
NASA DART mission: Spacecraft crashes into an asteroid in test of defense against killer space rocks,
The mission was designed to test whether a probe could knock a hazardous space rock away from a crash course with Earth.

MINI : NASA has successfully carried out the DART Mission in which a vending machine-sized spacecraft hit an Asteroid in the first-ever Planetary Defense Test.
NASA IS USUALLY quite cautious with its area probes. But this time, with DART, it’s different. A group of scientists has now intentionally plowed a craft right into a tumbling area rock at excessive speed. Mission accomplished.
It’s only a take a look at, an attempt to decide whether or not an asteroid may be nudged off its direction—a method that might be used to divert a near-Earth item on a collision direction with us if it’s noticed properly sufficient in advance. This specific take a look at issue is known as Dimorphos, and it’s approximately 6.eight million miles from Earth. It’s genuinely the diminutive member of an asteroid pair: It’s a moon of its plenty large sibling, Didymos.

The DART spacecraft is set the dimensions of a merchandising machine, and it became hurtling at a daft 14,000 miles in line with hour because it smashed into Dimorphos. As the craft sped alongside on its very last approach, the DART group—looking from challenge control—met every milestone with cheering and applause. “It went from a group of character pixels, and now you could see the form and shading and texture of Didymos, and you could see the equal factor with Dimorophos as we get nearer and nearer. This is so cool,” stated Lori Glaze, NASA’s Planetary Science Division director, mins earlier than impact.
The closing photographs from the craft’s digital digicam found out Didymos to be a barely egg-fashioned rock, affected by boulders and pockmarked with craters. The photos fast grew in length and then—the display went blank. Loss of signal. That showed the spacecraft’s collision, and the room rang out with the shouts of researchers:
“Oh wow!”
“Oh my goodness!”
“We were given it!”
'Spectacular! Amazing! Wonderous'
Glen Nagle, the Outreach and Administration Lead at NASA's Operations Support Officer, says there’s nevertheless a lot technology to be determined from today’s event.
"What a lovely little asteroid it is," he says.
"Its look indicates that it can be just like different asteroids which have been visited in current years, a unfastened rubble pile of house-sized boulders and car-sized and smaller rocks sure collectively through gravity.".
“Incredibly happy with our CSIRO crew withinside the manage room today. Just like DART, they have been laser focussed at the mission to hand and maintained communications lock proper at some point of those very last hours."
What is planetary defence system and what does it mean for humanity?
As per NASA scientists, a Planetary Defense System is a globally unifying effort to protect everyone living on Earth. The $325 million mission was the first attempt to shift the position of an asteroid or any other natural object in space to test the capability of humans of saving the Earth from potentially hazardous asteroid impacts in future.
"We're embarking on a new era, an era in which we potentially have the capability to protect ourselves from something like a dangerous hazardous asteroid impact," said Lori Glaze, director of NASA's planetary science division, NDTV reported.
