Moreover,
Nasa struck asteroid sparked completely:
Three years after the collision between the Dart probe. However, the Dimorphos asteroid, a study turns the consequences of the impact upside down. Similarly, It would seem that the detached rocks do not behave as planned, which throws disorder on future planetary protection missions.
It was a complete success. Consequently, In 2022, the Dart probe, designed by NASA, struck the asteroid Dimorphos, signing here the success of a planetary protection mission. Nevertheless, The idea being to see if we were able to deviate an asteroid in the event of a threat. Nevertheless, to the planet. Moreover, Indeed, Dimorphos had indeed changed trajectory. Similarly, But a new study published in The Planetary Science Journal On July 4. shows that the debris torn from the star do not behave exactly as what had been planned.
A study that “changes physics” – Nasa struck asteroid sparked completely
It turns out that several massive rocks nasa struck asteroid sparked completely that have detached themselves from the asteroid. have a momentum, that is to say a motionmotionthree times larger than planned, as if they had received an additional blow that projects them more. For one of the authors. Tony Farnham of the University of Maryland, ” This additional factor changes the physiquephysique that we must consider when we plan this type of mission ».
In total, the study was able to identify 104 rocks, measuring between 20 centimeters and 3.6 meters which were ejected from the asteroid. The simulations expected that all these small debris are distributed randomly around the main asteroid. However, this is not the case. Finally, they roughly gathered in two distinct groups, with nothing between the two. One in the south, rather dense and fast, and the other in the northeast, more scattered and slow. For nasa struck asteroid sparked completely what ? No idea! Tony Farnham adds that ” This means that there is an unknown process at work here ».
Details that can be major
The simulations of trajectories used are not yet precise enough to understand where exactly the uprooted rocks come from. which could have explained their behavior, but the authors hope that future studies will be able to better connect the state of the surface to the fragments in order to reconstruct the exact trajectory of each.
In the end, these are only details, because the Dimorphos trajectory has been established and the changes studied. On the other hand. if the situation really presents itself one day, these small subtleties will be taken into account so that the future planetary defense mission is effective.
What if the debris struck the earth? Or March?
Especially since this study is not the first to issue doubts about the behavior of Dimorphos nasa struck asteroid sparked completely debris. In August 2024, simulations showed that certain fragments could approach the land dangerously within thirty years. A few months earlier. researchers have made a simulation in which the largest rocks torn from Dimorphos could hit Mars in about 6,000 years.

In short, there are many uncertainties, but it could change at the end of 2026. At that time, the hera probe, built by theESAESAshould arrive on site and “note the damage” carried out by DartDart. The data harvested will be used to refine our still parcel knowledge on the subject. and to make sure that the day when an asteroid will really threaten the earth, we will be ready.
