They see the first sign from Spain that the asteroid impacted by Dart has deflected

On September 26, the morning of the 27th for Spanish time, NASA crashes a spacecraft traveling at more than 22,000 kilometers per hour against an asteroid the size of the Roman Colosseum, It was a deliberate move, the result of years of careful planning, engineering and global collaboration. it was DartWhich stands for ‘Double Asteroid Redirect Test’.

What surprised the scientists the effect was really great DART’s target asteroid, Dimorphos, is about 11 million kilometers away. Earth,

images taken by James Webb Telescope And this Hubble They showed an explosive collision, much larger than scientists had predicted. Both showed noticeable post-crash system brightnessWith large spikes of material ejected into space.



The first part of the mission was a hit and its success We were able to confirm this live, as the Dart itself included a camera that transmitted the images seen up to the moment of the collision., when the probe shattered against the surface of the dimorphos. DART’s companion, the Italian LICIACube satellite, also captured the impact from a “safe” distance, as well as ground-based telescopes in favorable locations to observe the event.

Now it’s time to check the second part of the mission: confirm that the first maneuver to twist a celestial body by kinetic impact has been successful, that is, Verify that Dimorphos has changed its orbit around Didymos -This small star The primary of this system – after the dart hit. And the first comments are promising.

Astronomers at Pujult Observatory (Barcelona) have observed the first indication that Dimorphos, a 160-metre-diameter rock, a little distracted, However, “we need to wait a few more days to confirm whether the divergence was expected or not,” they report from EFE.


Asteroid dimorphos just seconds after colliding with NASA's Dart spacecraft.

“Science goes beyond experiment and from that experiment we will have more information. To learn how to defend against dangerous asteroids in the future”, Pujalt observers recalled in a statement today.

From the Astronomical Park of the Pujalt Observatory, in collaboration with the Institute for Space Studies of Catalonia (IEEC), CSIC and NASA, monitor the event and have been able to capture images of the moments after the impact thanks to the 20-inch TGS telescope.

These images have been shared with researcher Josep Maria Trigo (IEEC), who in turn is part of the DART project team. NASA,

“All this information, and capture later in the nights to come, will serve Confirm how the dynamics change we humans have made in the past asteroids, All this will help in planning in future years to gain more insight into how we will be able to deflect asteroids that could be a threat to life on Earth”, the Pujalt astronomers have highlighted.

Within a few years, the mission of Hera European Space Agency (ESA) Will take an even closer look at the effects of the Dart Effect.


The HERA mission will carry two CubeSats to collect information about the binary asteroid system.
