ESA Science Image of the Week: This strangely meandering channel, carved on the Moon, is one of the Most Famous features on our nearest celestial neighbour. It shot to fame in July 1971 when two astronauts of Apollo 15 drove their lunar rover to its edge (Apollo 15 was launched to the Moon 45 years ago this week, on 26 July 1971, tomorrow in fact!).
