Hayabusa2 conducts first laser-ranging experiment with asteroid Torifune

JAXA says its Hayabusa2 spacecraft carried out the first successful laser-ranging experiment with an asteroid during a July 5 flyby of Torifune, the first target of its extended mission.

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.

Our reading

Our view is that this is a capability milestone rather than a scientific finding; the announcement gives no precision or measurement result for Torifune.

What to do or watch

Watch for JAXA to release the precision, duration, or measurement result from the July 5 Torifune laser-ranging experiment, since none was included in the announcement. The unresolved question is whether that data will make this a scientific finding rather than only a capability milestone.
