yaksha writes to tell us that the Indian Space probe, Chandrayaan, has become only the fourth nation to land a probe on the Moon. The 35-kg Moon Impact Probe touched down in what officials are describing as a "perfect operation." "Developed by ISRO's Vikram Sarabhai Space Centre of Thiruvananthapuram, the primary objective of MIP is to demonstrate the technologies required for landing a probe at the desired location on the moon. The probe will help qualify some of the technologies related to future soft landing missions. This apart, scientific exploration of the moon at close distance is also intended using MIP."
