NASA is a planetary defense system, since the weekly asteroid stalemate.
A Double Asteroid Double Driving Test (DART), an agency intends to conduct an experiment that reaches an average of 21,000 kilometers per hour at an asteroid level, because a similar collision could dump Earth to dangerous asteroids. .
According to NASA, the first mission of the DART mission is to show the kinetic effect of a small asteroid.
"DART's first mission to NASA would be to defend the impact of a kinetic impactor (an asteroid changing its orbit) to defend the future impact of future asteroids," Lindley Johnson said the head of the NASA head of the Washington-based defense chief. .
In recent years, space experts are worried about space rocks that can break into their future and can cause disasters, similar to those of an asteroid strike, which have erased the dinosaurs on this planet.
The space agency wants to use the DART system to hit the asteroid Didymos. This binary asteroid on Earth has two small rocks, Didymos A and B, and is not a threat to the Earth. Didymos is approximately 800 meters wide. The small Didymos B has a width of 160 meters and the orbit around the Didymos A.
NASA's nuclear space will be smaller when it reaches the rock between 2022 and 2024. There will be a collision around 11 million kilometers around the Earth.
This experiment will allow scientists to collect solid data on asteroids, which will impede impacts.
Nancy Chabot, at the Applied Physics Laboratory at the Johns Hopkins University and scientists from the DART project scientists, thinks that telescopes will play an important role in a successful mission.
"We need to know where this moon will be, so we can do this maximum deflection. We can give it a go when we know everything we know. We understand everything in the system, but exactly where it will be. [requires tracking] We want to try to get over it, "said Chabot Space.com.
The entire event will be followed by telescopes in the ground and two satellite space:
- The Italian lightweight Cubic Asteroid Picture, which will be sent to DART; and,
- The HERA Probe of the European Space Agency, according to which ESA invented a more detailed binary asteroid study.
