The LRO, in service since 2009, circles the moon from pole to pole every two hours while the moon rotates underneath it.<\/p>\n
A Nasa statement said it was challenging to capture the image. To photograph a specific spot on the moon, the spacecraft must wait until that location turns into view, which took six days in this case \u2013 and the spacecraft had to be tilted just right so that its camera pointed to the crater while it passed 96.5km overhead.<\/p>\n
Timing was the other challenge, Nasa said: \u201cIf the camera snapped even 10 seconds too early or too late, the target would drift off-centre by 10 miles [16km].\u201d<\/p>\n
The images they captured from different viewing angles brought out different features, including brighter and darker streaks fanning out around the crater.<\/p>\n
Nasa explained the darker streaks \u201care made of surface dust and rocks altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts\u201d that was thrown up by the collision from 45cm below the surface.<\/p>\n
The brighter streaks that hug the crater\u2019s rim were fresh material excavated from deeper underground.<\/p>\n
Finding the crater site was a global endeavour that brought together leading experts and hobbyists.<\/p>\n
Nasa said its Centre for Near Earth Object Studies incrementally refined the trajectory until identifying the location of impact, which it then provided to Korea.<\/p>\n
The Danuri team in turn sent its co-ordinates to Nasa\u2019s LRO team to help refine their follow-up imaging sequence.<\/p>\n
