A NASA spacecraft noticed one thing bizarre orbiting the moon. It was only a lunar neighbor.

NASA’s Lunar Reconnaissance Orbiter (LRO) snapped a wonderfully timed photograph because it crossed paths with one other spacecraft orbiting the moon.

The LRO, which has been orbiting the moon for 15 years, captured a number of photographs of the Korea Aerospace Analysis Institute’s Danuri lunar orbiter as the 2 spacecraft, touring in almost parallel orbits, zoomed previous one another in reverse instructions throughout three orbits between March 5 and March 6, in line with a statement from NASA.

Danuri, the Republic of Korea’s first moon-explorer, has been in lunar orbit since December 2022. On the time the images have been taken, Danuri was orbiting under the LRO, which was flying 50 miles (80 kilometers) above the moon’s floor.

Relative velocities between the 2 spacecraft have been about 7,200 miles per hour (11,500 kilometers per hour), NASA officers mentioned, making it difficult for the LRO’s slim angle digital camera to hone in on Danuri. The LRO’s digital camera publicity time was roughly 0.338 milliseconds, inflicting Danuri to look smeared throughout the picture and stretched 10 instances its measurement, because it traveled swiftly in the other way of the LRO.

“The LRO operations staff at NASA’s Goddard House Flight Heart in Greenbelt, Maryland, wanted beautiful timing in pointing LROC to the appropriate place on the proper time to catch a glimpse of Danuri,” NASA officers mentioned within the assertion.

NASA’s LRO had three alternatives to snap images of Danuri throughout shut flybys. For the primary snapshot, LRO was 3 miles (5 kilometers) above Danuri and oriented down 43 levels from its typical place wanting down on the lunar floor. In capturing the orbiter with its new positioning, Danuri appeared kind like a disk-shaped streak throughout the center of the picture.
