NASA: The DART satellite successfully changed an asteroid’s course

NASA

NASA claims to have been successful in deflecting an asteroid. It was to prevent an approaching cosmic object from wreaking havoc on Earth. Dimorphos was intentionally hit by the refrigerator-sized DART. In a historic test of humanity’s capacity to prevent an approaching cosmic object from wreaking havoc on Earth, NASA claims to have been successful … Read more

Moon shows impacts of dinosaur-killing asteroid; study

Moon shows impacts of dinosaur-killing asteroid
  • Dinosaurs may have been wiped out by meteorites that hit Earth billions of years ago.
  • China’s Change 5 probe has brought samples from the moon to Earth.
  • Analysis shows important events that affected the earth were part of other events happening in space.

Surprising information about the past of our solar system has been revealed by China’s Change 5, which brought samples from the moon to Earth. Science Advances has reported on one such discovery.

The dinosaurs may have been killed by the meteorites that struck our planet and the moon thousands of years ago, according to evidence discovered by scientists.

The lunar soil analysis demonstrated that important events that affected the earth were part of other events happening in space, say experts from Curtin University.

The team scrutinized tiny glass beads from two billion years ago to reach the conclusion.

Scientists said that those beads must have been created by the heat and pressure of meteorites. The silicate fragments might have developed as a result of volcanic eruptions.

Researchers employed numerous microscopic analytical techniques and geological surveys.

They discovered that some spherules, or lunar beads, were from the same era as the crater events that wiped out the dinosaurs.

Watch: NASA spacecraft hits asteroid during planetary defense test

Watch: NASA spacecraft hits asteroid
  • NASA’s DART spacecraft successfully collided with an asteroid on Monday night.
  • The $330 million mission was designed to see if a spaceship could alter an asteroid’s trajectory just by applying kinetic force.
  • The collision was the first test of a planetary defense system meant to stop an apocalyptic meteorite collision with Earth.

Ten months after DART’s launch, the National Aeronautics and Space Administration (NASA) webcast from the mission operations center outside of Washington, DC, depicted humanity’s first attempt to change the motion of an asteroid or any celestial body.

In the first test of a planetary defense system meant to stop an apocalyptic meteorite collision with Earth, NASA’s DART spacecraft successfully slammed into a faraway asteroid at supersonic speed on Monday.

The asteroid Dimorphos is about the size of a football stadium. It was 6.8 million miles (11 million km) from Earth when the cube-shaped “impactor” vehicle, barely bigger than a vending machine with two rectangular solar arrays, streaked into it at 7:14 pm EDT (2314 GMT).

DART, which was launched by a SpaceX rocket in November 2021, was mostly piloted by NASA flight directors until the last hours of the trip when autonomous onboard navigation software took over.

The mission operations center at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, kept a close eye on Monday night’s bullseye strike.

The DART onboard camera’s second-by-second views of the target asteroid, which grew larger and eventually covered the TV screen of NASA’s live webcast just before the signal was lost, caused cheers to break out in the control room as it was confirmed that the spacecraft had collided with Dimorphos.

The $330 million mission, which took seven years to build, was designed to see if a spaceship could alter an asteroid’s trajectory just by applying kinetic force, just far enough to keep Earth safe.

NASA spacecraft are positioned to collide with an asteroid

NASA spacecraft

The impact is scheduled for Monday at 23:14 GMT (00:14 BST, Tuesday). Dart won’t be able to tell its target apart from Didymos until the last 50 minutes or so. The spacecraft’s trajectory must then be modified by navigational software for a direct strike. The American space agency is about to send a spacecraft hurtling … Read more

NASA Announces an SUV Sized Asteroid Passes by Earth

WASHINGTON: The Earth almost dodged a doomsday following an asteroid the dimension of an SUV passed Earth at a high speed of 1,830 miles (2,950 kilometers). Making it the nearest asteroid ever witnessed lingering by Planet Earth, stated by NASA this Tuesday. If the asteroid was on the way of the collision with Earth, as … Read more
