The cable system, formerly used for space elevators, connected the Moon and Earth, and can now be used to tie asteroids together.
Many measures to prevent asteroids from colliding with the Earth have been proposed, including the use of a probe to pierce asteroids to discover their mass and composition, thereby controlling deviations. . However, this plan faces a lot of risks, because it can accidentally create debris to fall to Earth.
Fortunately, scientists now have a more secure solution. According to the Parabolic Arc, Flaviane Venditti and colleagues at Central Florida University have proposed using a cable system to prevent the impact of asteroids.
Specifically, the cable system previously used for purposes such as space elevators, connecting the Moon and Earth, will now be used to tie a potentially asteroid to Other smaller asteroids. From there, change the center of mass of both and raise them to another orbit more safely.
However, this method still has certain disadvantages. (Photo: Engadget).
This approach, compared to the original probe solution, not only prevents asteroid hazards, but also minimizes the risk of fragmentation making them more likely to fall to Earth, causing damage. widespread.
To test the effectiveness of the method, Venditti's team used the asteroid Bennu as a test subject. According to Venditti, the team simulated computers to calculate the dynamics of wiring under various conditions. The conclusion shows that this way is feasible to use in planetary defense systems.
However, the above system still has certain disadvantages. One of them is that they take a lot of time compared to traditional high-impact methods such as spacecraft or rockets.
Due to the work with the detection and coordination system, if any negligence occurs due to lack of vigilance, the process will be delayed. Moreover, it is not easy to find another small asteroid.
