Agency says Dart mission shows it is 'very possible' to save Earth from impact of an asteroid.

The Hera mission is expected to launch in October 2024 and arrive towards the end of 2026. These are considered to be those close to 500ft or wider in diameter. It is about 500 feet across and orbits another nearby larger asteroid.

NASA's DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world's first test of a planetary defence system, ...

Although none are known to pose a foreseeable hazard to humankind, NASA estimates that many more asteroids remain undetected in the near-Earth vicinity. Smaller asteroids are far more common and present a greater theoretical concern in the near term, making the Didymos pair suitable test subjects for their size, according to NASA scientists and planetary defense experts. DART flew directly into Dimorphos at 15,000 miles per hour (24,000 kph), creating the force scientists hope will be enough to shift its orbital track closer to the parent asteroid. Whether the experiment succeeded beyond accomplishing its intended impact will not be known until further ground-based telescope observations of the asteroid next month. Last year, NASA launched a probe on a voyage to the Trojan asteroid clusters orbiting near Jupiter, while the grab-and-go spacecraft OSIRIS-REx is on its way back to Earth with a sample collected in October 2020 from the asteroid Bennu. Earlier calculations of the starting location and orbital period of Dimorphos were made during a six-day observation period in July and will be compared with post-impact measurements made in October to determine whether the asteroid budged and by how much.

Tech giant Google took it upon itself to launch its own type of celebration following NASA's Double Asteroid Redirection Test (DART) mission successfully ...

The company's Google Doodles on Google.com frequently feature historical figures or events on anniversaries. Neither of the asteroids, which are located about 7 million miles away, pose any threat to Earth. If you Google "NASA DART" or "NASA DART mission" it will trigger an animation featuring a spacecraft hitting the "News" tab and knocking your search results off-kilter.

[The dramatic series](https://twitter.com/NASA/status/1574539270987173903?s=20&t=STv37mPgMsVUfvuscEyHxg) shows the asteroid gradually filling the frame, moving from a faraway mass floating in the darkness to offering an up-close and personal view of its rocky surface. Because it doesn't carry a large antenna, it adds, those images will be downlined to Earth "one by one in the coming weeks." Nonetheless, NASA officials [have hailed the mission ](https://www.nasa.gov/press-release/nasa-s-dart-mission-hits-asteroid-in-first-ever-planetary-defense-test)as an unprecedented success. "DART's success provides a significant addition to the essential toolbox we must have to protect Earth from a devastating impact by an asteroid," Lindley Johnson, NASA's planetary defense officer, said in a statement. 2021 on a one-way mission to test the viability of kinetic impact: In other words, can NASA navigate a spacecraft to hit a (hypothetically Earth-bound) asteroid and deflect it off course? It's the high point of a NASA project known as the Double Asteroid Redirection Test, aka DART, which started some $300 million and seven years ago.
