Schoolchildren direct moon mission
A Nasa spacecraft in orbit around the moon has sent back five dozen new images of the lunar surface including a view of the far side with Earth in the distance.
Pupils from an elementary school in the US state of Montana directed the spacecraft to snap pictures as part of a project headed by Sally Ride, the first American woman in space.
The images were returned earlier this week.
Twin Nasa probes entered lunar orbit over the New Year's weekend on a mission to study the gravity field.
During non-critical parts of the mission, select students get to choose camera targets.
The Montana students got their role for winning a Nasa-sponsored contest that renamed the craft Ebb and Flow.
