Why NASA is crashing a spacecraft into an asteroid

The threat from asteroids and comets Millions of cosmic bodies, like asteroids and comets, orbit the sun and often crash into the Earth. Most of these are too small to pose a threat, but some can be cause for concern. Near-Earth objects include asteroids and comets whose orbits will bring them within 120 million miles (193 million kilometers) of the sun. Astronomers consider a near-Earth object a threat if it will come within 4.6 million miles (7.4 million kilometers) of the planet and if it is at least 460 feet (140…

The unpredictabilities of NASA’s wild plan to ram an asteroid off course

It’s the stuff of sci-fi disaster films. What do we do if an asteroid is on a collision course with our home planet? One option might be the use of brute force, sending a spacecraft to intervene in the asteroid’s trajectory to simply knock it off course. Today, NASA will explore this possibility with a world-first mission to crash into the asteroid Dimorphos and alter its orbit. We checked in with the team behind this landmark mission to understand some of the mechanics at play.A rare opportunity…

A NASA Spacecraft Will Collide With an Asteroid on Monday. Watch Live Here : ScienceAlert

On September 26 at 11.15 pm UTC, NASA's DART mission (Double Asteroid Redirection Test) will be the first to deliberately and measurably change the motion of a significant body in our Solar System.In other words, it will smash into an asteroid.The mission will provide the first test of a technique that could be used in the future – to redirect any asteroids we detect on a collision course with Earth.You can view a livestream below:https://www.youtube.com/watch?v=-6Z1E0mW2ag frameborder="0″ allow="accelerometer; autoplay;…

NASA is about to crash a spacecraft into an asteroid

Dimorphos is a lump of space rock so far away from Earth that we don’t even know what it looks like — and on Monday, we’re going to smash it with a spacecraft. The Double Asteroid Redirection Test (DART) will be traveling at more than 14,000 miles per hour when it hits the asteroid, in what has to be one of the most metal science experiments of all time. DART is a NASA effort to see if it can change an asteroid’s movement in space. It’s being billed as the world’s first “planetary defense test mission” — a test run to…

How to Watch NASA’s DART Spacecraft Crash Into an Asteroid

An artist’s depiction of the DART Spacecraft approaching the asteroid. Illustration: NASAThe demise of DART is finally upon us, as the NASA spacecraft is on a collision course with the tiny Dimorphos asteroid. Here’s how you can watch this hugely important experiment to deflect an asteroid. Short for Double Asteroid Redirection Test, the DART mission is the first test of kinetic impactor technology as a means of deflecting asteroids that could be headed towards Earth. Although Didymos means no harm to our planet, the epic

Can We Really Deflect an Asteroid by Crashing Into It? Nobody Knows, but We Are Excited to Try

NASA's Double Asteroid Redirection Test (DART) spacecraft is designed to be a one hit wonder. It will end its days by crashing into an asteroid at 24,000 kilometres per hour on September 26. Launched from Earth in November 2021, DART is about the size of a bus and was created to test and prove our ability to defend Earth from a dangerous asteroid.Landing a direct hit on a target from 11 million kilometres away isn't easy. But while this sounds far, the asteroid was actually selected by NASA because it is relatively close…

Webb and Hubble Telescopes Will Observe NASA’s Asteroid Deflection Test

A host of telescopes will be watching, including the Hubble and Webb space telescopes.“We are moving an asteroid,” Tom Statler, DART program scientist, told reporters yesterday at a NASA press briefing. “We’ve never done that before,” he added, saying “it’s kind of

Water Drop Discovered on Ryugu Asteroid Offers Clues to Origins of Life on Earth

Specks of dust retrieved by a Japanese space probe from an asteroid some 300 million kilometres from Earth have revealed a surprising component: a drop of water, scientists said Friday. The discovery offers new support for the theory that life on Earth was seeded from outer space.The findings are in the latest research to be published from the analysis of 5.4 grams of rocks and dust gathered by the Hayabusa-2 probe from the asteroid Ryugu."This drop of water has great meaning," lead scientist Tomoki Nakamura of Tohoku…
