Mumbai, July 17 - The Reliance Anil Dhirubhai Ambani Group's film and entertainment arm Adlabs has been helping restore invaluable footage of the Apollo 11 mission that had put the first human on Moon 40 years ago.

The restored images, as part of an ongoing programme, include the sequences showing Neil Armstrong's historic descent down the ladder of the spacecraft and installing the US flag on the Moon.

The restoration work was initiated by Lowry Digital, a wholly-owned subsidiary of Adlabs Films, on behalf of the National Aeronautics and Space Administration (NASA), according to an announcement by Adlabs here Friday.

Lowry Digital has completed the initial phase of the restoration of a 150-minute-long footage beamed to NASA from Apollo 11. The entire restoration work is expected to be completed by September, the company said.

The restoration mission was commissioned by NASA as part of the 40th anniversary celebrations of the 1969 Moon landing July 20. Portions of it will be shown to the media in Washington later Friday.

Apart from Armstrong's descent on the Moon, the footage also shows images captured by him and his associate Edwin Buzz Aldrin, the second man to set foot on the Earth's only satellite during that mission.

Adlabs Film chief executive Anil Arjun said the footage is being digitally restored using Lowry Digital's proprietary Lowry Process.

'We feel honoured to have been selected by NASA to carry out the restoration of this historic footage, which will be lauded by generations to come.
