Japan's asteroid probe Hayabusa2 set for final touchdown

Hope all goes well and have a safe landing so that it may return safely to Earth to enlighten us about our Universe.

Good luck indeed.

Any word of when we ought to learn of their findings?

It's a big event. Good luck. Go Hayabusa2" Go!

It's mind boggling that they can plan and carry out a mission with such precision. Well done to the team!

To get at those crucial materials, in April an "impactor" was fired from Hayabusa2 towards Ryugu in a risky process that created a crater on the asteroid's surface and stirred up material that had not previously been exposed to the atmosphere.

Asteroids don't have an atmosphere. The only thing these materials will not have been exposed to is solar wind and the odd speck of dust.
