Around 6 pm on Thursday night, the Japanese spacecraft Hayabusa 2 touched down on Ryugu—a distant asteroid.
The craft wasn’t there to make friends, something it promptly proved by firing a bullet into the asteroid. The goal, according to officials at the Japan Aerospace Exploration Agency, is for Hayabusa 2 to collect debris from the asteroid to bring back to Earth for testing.
It marks the completion of a long and arduous journey for Hayabusa 2. The craft was deployed in 2014, taking nearly four years to complete its 2 billion mile journey to Ryugu’s orbit in June of 2018. After dropping rovers onto the asteroid’s surface for months, Hayabusa 2 finally landed on the rock itself to fire the bullet and collect the subsequent debris.
The craft was reportedly successful in gathering the sample.

Now, the craft will make the treacherous 3 billion mile journey back home, where it’s expected to drop the sample at a location over Australia, but it won’t reach Earth’s atmosphere until at least 2020.
Judging by Twitter, it will be arriving to a warm reception.
#Humanity is awesome, #Space #Science edition: Japanese robot Hayabusa 2 flies to an asteroid, orbits it for a year, drops probes, does a precise soft touchdown in microgravity to grab a sample, and will fly all the way back to Earth with that sample.https://t.co/7kCIiYEXcD

Truly exciting to hear what's happening 300mill. km away from earth. Safe travel home! https://t.co/T3ewZhkKUX

Americans also had the most American response ever.
