What a great achievement for Nigeria! From Jonathan Amos on the BBC: Nigeria's latest Earth observation satellites have returned their first pictures. The spacecraft, launched on 17 August, give the African nation a powerful new capability to map its own lands and other parts of the globe.

The first picture released from the Nigerian pair is of New Zealand's biggest city, Auckland. It was acquired by NigeriaSat-X, and reveals the buildings and the landscape surrounding this major urban centre.
