US EditionNew observations show the aftermath of a spacecraft intentionally colliding with an asteroid
- In September 2022, NASA's DART spacecraft struck Dimorphos, shortening its orbit by 0.15 seconds and 2,360 feet, confirming deliberate orbital change.
- As a kinetic impactor test, the DART spacecraft showed it can nudge an asteroid's orbit, with debris from Dimorphos roughly doubling momentum transfer, researchers said.
- Dimorphos measures 525 feet in diameter while Didymos spans 2,560 feet and has about 200 times more mass; each solar orbit lasts 769 days, slowing over 10 micrometers per second.
- Scientists say Earth remains safely out of the asteroids' way, and the European Space Agency's Hera spacecraft will follow up at Didymos and Dimorphos in December 2026, tagging along for months of surveying.
- As Makadia warned, surface 'probability maps' are vital to select impact sites that avoid gravitational 'keyholes' and reduce impact risks.

In 2022, a NASA spacecraft intentionally crashed into the small Dimorphos asteroid during a planetary defense test. The objective was to assess whether humanity could protect the Earth from cosmic threats, such as space rocks. New observations now reveal that the planetary defense test was a success, altering both the orbit of Dimorphos and that of a larger asteroid, Didymos. Dimorphos and Didymos are a binary pair, which means that asteroids or…
In September 2022, NASA's DART (Double Asteroid Redirection Test) mission demonstrated that it was possible to alter an asteroid's orbit by kinetic impact. After the DART probe crashed with Dimorphos (160 metre diameter), the asteroid, which is part of a binary system and orbits around a much larger one, Didymos (780 metres), reduced its orbital period by 33 minutes.
NASA has achieved a historic feat: humanity has become the first to change the orbit of an asteroid around the Sun. This is a huge milestone for planetary protection.
We are living in the dystopia of a world war, mad geopolitics, terror of attacks, bombed civilians, and the poor Ukraine that has gone into the background and continues to be bombarded by Putin more than before, but I give you a little astronomical news
