Hayabusa 2: search for vital vestiges
In 2014, the Japanese space agency will send a probe called Hayabusa 2 to the asteroid 1999 JU3. After laying on the asteroid during the summer of 2018, the material of the asteroid will be collected and will rise to Earth in 2020.
The purpose of this essay is to demonstrate the importance that asteroids have had in the origin of life on Earth and to do so they want to collect the material they contain. How, then?
The collection of materials will take place in two ways. On the one hand, the probe will release bullets the size of the ends of the fingers and pick up the material they will release when they collide with the ground. On the other hand, from a certain distance, a two-kilogram explosive is thrown with a two-meter diameter crater, which is then introduced into the crater and collects the material from it. This material will be different from the previous one, as it will be protected from solar rays below the asteroid soil.
A few years ago, we wanted to do a similar process with the Hayabusa probe, but because it was a breakdown, the only thing that could be picked up was a bit of dust.
