India marked its presence on Moon tonight to be only the fourth nation to scale this historic milestone after a Moon Impact Probe with the national tri-colour painted successfully landed on the lunar surface after being detached from unmanned spacecraft Chandrayaan-1.

Joining the US, the erstwhile Soviet Union and the European Union, the 35-kg Moon Impact Probe(MIP) hit the moon exactly at 8.31 PM, about 25 minutes after the probe instrument descended from the satellite in what ISRO described as a "perfect operation".

Miniature Indian flags painted on four sides of the MIP signalled the country's symbolic entry into moon to coincide with the birth anniversary of the country's first prime minister Jawaharlal Nehru, observed as Children's Day.

"It will signify the entry of India on Moon," an ISRO official said. The MIP is one of the 11 scientific instruments (payloads) onboard Chandrayaan-1, India's first unmanned spacecraft mission to Moon launched on October 22 from Sriharikota spaceport.

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.
