The lift-off of the Sea Launch Zenit-3SL launch vehicle carrying the Inmarsat-4 satellite ha been delayed until Tuesday.

The reason for the delay was due to an automated halt in the launch countdown system, prior to fueling. The launch team is currently reviewing the data from this system.

On Sunday, the team will assess readiness to resume the countdown for launch on Monday, November 7.

The Zenit-3SL launch vehicle is to put the 5,958 kg I-4 satellite into a geosynchronous transfer orbit.

Built by EADS Astrium for Inmarsat, the I-4 satellite is to ensure data transmission to North and South Americas for over 13 years.

Sea Launch was created in 1995 as a consortium that included Boeing (United States), Kvaerner Group (Norway), Russian space corporation Energia (Moscow), the Yuzhnoye design bureau (Ukraine) and the Yuzhmash production association (Ukraine).

Preparations for the launch lasted 72 hours. Specialists conducted the final tests on the launch system and the satellite itself.
