William Robinson writes: After 18 days journey, Chandrayan, the moon mission of India, has entered Lunar orbit. The manoeuvre was described as crucial and critical by scientists, who pointed out that at least 30 per cent of similar moon missions had failed at this juncture, resulting in space crafts lost in outer space. The lunar orbit insertion placed the Chandrayaan in an elliptical orbit with its nearest point 400 to 500 kilometres away from the moon and the farthest, 7,500 kilometres. By November 15, the spacecraft is expected to be orbiting the moon at a distance of 100 kilometres and sending back data and images. The Chandrayaan is also scheduled to send a probe to the moon's surface.
