Analyzing samples retrieved from the asteroid Ryugu by the Japanese Space Agency's Hayabusa2 spacecraft has revealed new insights into the magnetic and physical bombardment environment of interplanetary space.

This relentless high-speed flow of charged particles from the sun fills interplanetary space.

"If successful, it would be China's first samples collected from interplanetary space," Zhang said, adding that a spacecraft will be sent to fly around and then land on the asteroid to collect the samples.

Otherwise, the mission would drift off into interplanetary space.

They then pumped the chamber to a vacuum — to mimic the conditions of interplanetary space — and fired tiny aluminum spheres at the meteorites.
