Nilesat 201 will replace Nilesat 101 which was expected to terminate its mission in 2013.It also meets the growing demands for Nilesat space capacities within the Middle East and North Africa (MENA) region, to maintain Nilesats leading position among the regional satellite operators.

Mission Overview

CoverageIts coverage includes MENA region, including the GULF region, and full coverage of Sudan and East of Africa.

Launching Ariane 5.Liftoff was delayed nearly 44 minutes due to storms at the spaceport.Powering up to 2.9 million pounds of thrust, the launcher surpassed the speed of sound42 seconds after liftoff, weathering intense aerodynamic pressures as it rocketed into the stratosphere before shedding the two strap-on rocket motors, which supplied the bulk of the energy required to push the Ariane 5 into the sky.The rocket's core liquid-fueled core stage kept firing until the mission's nine-minute point, when it shut down and separated to fall back into theAtlantic Ocean. An upper stage HM7B engine ignited for a nearly 16-minute burn aiming for an egg-shaped orbit stretching from 155 miles to 22,236 miles above Earth.
