Hayabusa2 lands on an asteroid and returns amazing images to prove it – TechCrunch

The Japanese Hayabusa2 mission on the asteroid Ryugu is an ambitious mission. The team recently made the decision to raise the stakes with a second touchdown on the surface of the space stone. Not only has everything gone as planned, but we now have the best shots of the surface of an asteroid to be sent back to Earth.

Hayabusa2 is a very, very cool mission. The basic idea is:

  1. Fly to the nearby asteroid
  2. Land and sample the surface
  3. Blow into a crater with a space gun
  4. Landing and tasting the crater
  5. Send the resulting samples to Earth

Fabulous, no? And the intrepid spaceship has just completed step 4 earlier today, touching amazing images while realizing its science. This one was taken just as it appeared on the surface:

No matter how many things could have resulted in a second touchdown that was too risky or useless. Fortunately, they concluded that the risk was acceptable and that it would be an important feat in more ways than one.

The previous sample was taken from the undisturbed Ryugu surface, more or less as it has been for many years. Then came the space gun: a 2-kilogram copper bullet propelled by an explosion shaped at 4,400 miles at the hour. It made a crater, okay! The probe cleared on the other side of the asteroid to avoid being hit by debris.

What has been exposed is a surface that has never been sampled before by human hands or robots – the soft belly of an asteroid. This could tell us a lot, which is why the team decided to start it. It's just great and historic.

It does not stay long, there are more twists than "lands". I gathered them in the gif you see above. Some other shots show the area before the craft descends.

There is not much more information than this at the moment, since a more detailed breakdown will follow, explains the website of the Hayabusa2 mission. For now, savor the face of the team after this incredible feat:
