NASA to crash spaceship on asteroid

NASA is preparing to conduct a mission that will change the world forever. The space agency has announced its intention to crash one of its spacecraft into an asteroid. This collision could create debris capable of causing severe damage on Earth if it was not sufficiently dispersed in space by the impact, or if it were drawn back together by gravity. The

mission will be to study the effects of the collision on the asteroid itself, as well as on any new debris that is ejected into space. NASA wants to see how much damage can be done by just one of its spacecraft.

The launch of NASA’s DART Double Asteroid Redirection Test mission has been scheduled for 2021, and its impact with the smaller of the two asteroids in the Didymos (did-e-mos) system will likely occur in 2022. The asteroid being targeted has been named ‘Didymoon’ (Did-e-moon), which is derived from Greek and describes double asteroids ones that are made up of two rocks orbiting each other.

NASA hopes that by directly studying Didymoon they will be able to better predict the number of potentially hazardous asteroids that may pose a risk to Earth. The majority of these are believed to consist of metals, which means that if DART’s collision with Didymoon is successful, it would represent an extremely cost-effective method of deflecting any asteroids away from us.

NASA’s Double Asteroid Redirection Test mission DART is being developed as a joint partnership between NASA and the John Hopkins University Applied Physics Laboratory (APL). The spacecraft will be jointly steered by both bodies, but its navigation camera system will be provided by Malin Space Science Systems (MSSS) in San Diego, California.

The mission will be the first to demonstrate that asteroids can be deflected away from Earth, which is why it is so important not to muck up. DART’s ‘kinetic impactor’ was successfully tested during a 2014 trial on the smaller of two asteroid moons orbiting the larger body known as Didymos. This moon has been named ‘Didymoon’ (Did-e-moon), which describes double asteroids ones that are made up of two rocks orbiting each other.

NASA hopes that by directly studying Didymoon they will be able to better predict the number of potentially hazardous asteroids that may pose a risk to Earth. The majority of these are believed to consist of metals, which means that if DART’s collision with Didymoon is successful, it would represent an extremely cost-effective method of deflecting any asteroids away from us.

NASA has identified 900 potentially hazardous ?metallic asteroids whose path around the sun brings them close to or crosses Earth?s orbit. It says about 7pc are very large, and if one headed directly for us there would be no way to deflect it aside.
