Tiny Fragments of a 4-Billion Year Old Asteroid Reveal Its History

In June 2018, Japan’s Hayabusa 2 mission reached asteroid 162173 Ryugu. It studied the asteroid for about 15 months, deploying small rovers and a lander, before gathering a sample and returning it to Earth in December 2020.

The Ryugu sample contains some of the Solar System’s most ancient, primitive, and unaltered material, opening a window into its earliest days about 4.6 billion years ago.

In an expected move, the Japan Aerospace Exploration Agency (JAXA) has announced a mission extension for their Hayabusa2 spacecraft. Hayabusa2 will be sent to rendezvous with another asteroid in a few years time.

It’s target is 1998 KY26, a near-Earth object (NEO) less than a kilometer in diameter. But it’ll take a while and some maneuvering around other objects in the Solar System to reach its goal. JAXA says the spacecraft will arrive at the asteroid in July 2031.
