The Japanese space agency said Sunday the capsule from its Hayabusa2 space probe was collected from the Australian desert in "perfect condition," hopefully containing samples from the Ryugu asteroid that could help explain the origins of life.

The capsule appeared as a bright fireball lasting several dozen seconds as it re-entered Earth's atmosphere before dawn, its protective heat shield glowing as it reached temperatures of approximately 3,000 degrees Celsius.

If the mission was successful, the capsule will contain two samples from the Ryugu asteroid, including the first subsurface asteroid sample ever collected. Scientists believe that organic matter and water existed on the asteroid when the solar system was created around 4.6 billion years ago.
