Crews reported seeing an odd glow on the lunar horizon just before sunrise. The phenomenon, which prompted a notebook sketch by Apollo 17 Commander Eugene Cernan, was unexpected because the airless moon lacked atmosphere for reflecting sunlight.

The spacecraft, known as Ladee, is scheduled to be launched at 11.27pm EDT (11.27pm Singapore time) on Friday (11.27am Singapore time, Saturday) from Nasa's Wallops Flight Facility on Wallops Island, Virginia.
