JAXA's Hayabusa2 spacecraft carried out the first successful laser-ranging experiment with an asteroid during a July 5 flyby of Torifune, the agency says.
Torifune is the first exploration target of Hayabusa2's Extended Mission. JAXA says the milestone will advance the capabilities of space agencies pursuing future missions to near-Earth asteroids and other deep-space objects.
The announcement gives no precision, duration or measurement result for Torifune, so this stands as a capability milestone rather than a scientific finding.
