THE'ESA, the European space agency, has approved Hera: a mission that aims to deflect asteroids. The goal is to find out if our technologies are sufficient or not to guarantee greater security for our planet and to prevent, in the worst case, an Armageddon.
The test, which will cost 320 million dollars, will see the collaboration of ESA and NASA. The two space agencies will send two vehicles to a double asteroid system called Didymos. The probe DART of NASA will crash into the smaller asteroid, named Didymoon, at a speed of 13,320 miles per hour, while the Italian cubesat LICIAcub will record the whole.
Hera will come later to map the impact crater and measure the asteroid mass; will carry two CubeSats that will be able to fly over the surface of the celestial body and then land and free small drones, the size of a briefcase. Their task will be to capture the "vital data" on the character created, so as to provide scientists with important information such as the asteroid mass. The aim, said ESA, is "to transform the deflection of asteroids into a well-known technique of planetary defense". It will be interesting to follow the story closely, because it is an important test for the safety of the Earth: in fact many have assumed that, should an asteroid impact against our Planet, it could be a big problem for humanity as the current technology would still not be sufficient for complete protection.
Meanwhile, NASA researchers have succeeded in creating the first global map of Titan, Saturn's largest moon. In this way, the space agency could have a better idea of where to drive their lander, but also know what to expect when it lands. The goal is to reach the surface of Saturn's frozen moon in 2034.
