Dust From Japan's Asteroid-Blasting Probe Returns to Earth

Long-time Slashdot reader reminds us that in 1999 scientists discovered the asteroid Ryugu flying 300 million kilometres (or 186,411,357 miles) from earth. In 2014, Japan launched a probe to collect samples from it. Today those samples returned to earth. The International Business Times shares pictures and report:In a streak of light across the night sky, samples collected from a distant asteroid arrived on Earth after being dropped off by Japanese space probe Hayabusa-2. Scientists hope the precious samples, which are expected to amount to no more than 1 gram of material, could help shed light on the origin of life and the formation of the universe. [That's 0.00220462262185 pounds.] The capsule carrying samples entered the atmosphere just before 2:30 am Japan time (1730 GMT Saturday), creating a shooting-star-like fireball as it entered Earth's atmosphere. "Six years and it has finally come back to Earth," an official narrating a live broadcast of the arrival said, as images showed officials from Japan's space agency JAXA cheering and pumping their fists in excitement... The capsule was recovered in the southern Australian desert, and will now be processed before being sent to Japan... The probe collected both surface dust and pristine material from below the surface that was stirred up by firing an "impactor" into the asteroid. The material collected from the asteroid is believed to be unchanged since the time the universe was formed... Scientists are especially keen to discover whether the samples contain organic matter, which could have helped seed life on Earth.
