DART

Artist's impression of the DART spacecraft on its way to the Didymus-Dimorphus asteroid system. The targeted impact with Dimorphus changed not only its orbit around Didymus, but also the system's orbit around the Sun.

The DART impact changed not only the asteroid's orbit around its companion, but also the system's orbit around the Sun.

New research shows that the spacecraft's deliberate crash pushed the entire Didymus-Dimorphus asteroid system, providing the first evidence that humans altered the solar orbit of a natural body.

Gaia solves the mystery of asteroid rotation: Collisions and internal friction reveal the structure of "debris piles"

Analysis of data from the European Space Agency's Gaia mission reveals a sharp gap in the rotation patterns of asteroids – the result of a struggle between collisions and internal friction – and provides a new tool for deciphering the internal structure
These images, showing the material ejected from around the near-Earth asteroid that was struck, were taken during the approach (with Didymus at top left) and the receding (with Didymus at top right) of the LICIACube satellite, which flew over the area a few minutes after the impact and recorded its aftermath. The ejection field consists of an asymmetrical cone of dust containing streams and filaments, as well as more than 100 meter-sized rocks ejected in various directions.

NASA's DART mission deflected an asteroid – but released a swarm of space rocks

Astronomers at the University of Maryland have discovered that an unexpected burst of rock fragments released during the DART mission carried with it three times more momentum than the spacecraft itself – a discovery that provides important new insights

NASA faces a (theoretical) 72% chance of an asteroid impact

NASA's biennial exercises simulate an asteroid impact to prepare international response strategies. These scenarios use real data to test emergency preparedness and explore diversion techniques like the DART mission

Technion researchers are partners in the HERA space mission: first attempt in history to divert an asteroid from its orbit
This image from NASA's Hubble Space Telescope from Oct. 8, 2022, shows debris blasted off the surface of Dimorphus 285 hours after the spacecraft's intentional impact with the asteroid on Sept. 26. The shape of the tail has changed over time. Scientists continue to study the material ejected from the asteroid as impact and how it moves through space, to better understand the asteroid.

NASA confirms that the DART impact significantly changed the asteroid's trajectory

The duration of Dimorphos' orbit of the asteroid Didamos was shortened by about half an hour

NASA's DART spacecraft is aimed at impacting the target asteroid Dimorphos with the aim of deflecting it on September 26

DART, which is the world's first attempt to change the speed and trajectory of an asteroid in space, is trying a method to deflect asteroids that could be useful if such a need arises in the future to protect Earth.

When cinema and reality come together in the mission of dropping an asteroid: the DART spacecraft is launched

The DART spacecraft that will try to change the orbit of a double asteroid will be launched on 24/11. The producers of the space disaster film "Don't Look Up" on Netflix, about the discovery of an asteroid that threatens the Earth, have timed its rise
