Dart has collided with Dimorphos, what other planetary defense proposals do we have?

NASA’s Dart probe impacted yesterday morning against the 160-metre-diameter asteroid Dimorphos. This celestial body orbits another asteroid called Didymos and both are located at a distance of about 11 million kilometers from Earth. They are no threat to humanity

Through this collision the US space agency wants to modify the trajectory of Dimorphos. Something that they will check if they have achieved in the coming weeks. Although this asteroid poses no threat, it allows NASA scientists to Experiments on the use of space technology for planetary defense.

European Space Agency (ESA) collaboration in DART mission which will launch in 2024 HERA, a project with which it intends to study in detail how the accident affected the NASA probe In the dimorphose in the long run. However, these programs are not the only ones to study how they can halt the progress of an asteroid coming dangerously close to Earth.



Space Defense Projects

The Chinese National Space Administration (CNSA) said they are preparing a plan to divert the path of potentially dangerous asteroids. As he remarked in April of this year, he anticipated that it would be ready Duration of 4-5 years.

CNSA Deputy Director Wu Yanhua announced that the first phase of the project will be “Improving Surveillance and Early Warning System” of near-Earth objects”. Thus, he sought to detect asteroids that represented a real threat to Earth earlier and more efficiently, in order to study the techniques needed to eliminate them.

The asteroid will be 3,241,785 km away from Earth tomorrow.

In addition, the CNSA warned that they were careful to develop a “Simulation Software” Defense against nearby asteroids.” By about 2026 they expected a ship to be ready for testing. impact missionAs NASA has done with Dart.

In parallel with the DART and China missions, Patrick King, a physicist at the University of Maryland (USA), thought of developing a nuclear missile that exploded next to the asteroid to destroy it.

King elaborated for Science Alert that there was a problem with his theoretical plan: “You should A model that calculates the classes of all fragments,

As he emphasized, the calculation of this meteorite disruption was “far more complex than the calculation of a simple deflection.” However, King assured that it should be analyzed and evaluated whether it is worth going ahead with such a project.


On June 11, it will again pass close to the Earth.

Here . Spanish participation in

The Spanish business group GNV is behind the development of the Guidance, Navigation and Control (GNC) system for ESA’s HERA mission. Using this technology the European Space Agency will be able to maintaining and controlling the classroom of spacecraft depending on the mission.

Thanks to the GNVs, European researchers will be able to guarantee the correct navigation of the ships that they will send to Dimorphos and Didymos to collect data on the binary asteroid system. The last thing about the project dates back to September 2020, when the two sides signed the agreement.
