Ariane's official website noted, just a couple
hours before the 160th flight was to have blasted off last night
[Tuesday]: "Tonight's liftoff of Arianespace Flight 160 was delayed
after one of the mission's two clients requested additional
verifications on its satellite payload.
"The Ariane 5G launcher and its dual payload are in a safe mode
on the launch pad.
"Additional information on the mission's rescheduling will be
provided during the morning hours of April 9 (Kourou time).
"Arianespace was notified of the client's need for additional
satellite verifications prior to the startup of fueling activity
with the Ariane 5's cryogenic core stage. As a result, the
countdown activity was stopped before any of the stage's liquid
oxygen/liquid hydrogen propellant had been loaded."
Flight 160 will carry the 2,950-kg. INSAT 3A satellite, produced
by the Indian Space Research Organisation, and GALAXY XII - a 1,760
kg.-payload built by Orbital Sciences Corporation for PanAmSat.
