The Japanese lunar orbiter Kaguya has completed its main mission. But there’s one final scientific endeavor: It will slam into the moon’s surface at about 2:30 p.m. ET (18:30 UT) today.
Amateur skywatchers with telescopes and some experience might see the event from Earth. “The timing favors telescopic observers in east Asia, Australia and New Zealand, who may be able to see a brief flash of light or a plume of debris rising from the Moon’s southeastern limb,” according to Spaceweather.com.
