DARMSTADT,
Germany -- The launch of Europe's MetOp-A weather satellite was delayed for the
second straight day Oct. 18 because of high winds above the Baikonur Cosmodrome
launch site in Kazakhstan, launch officials said. A new attempt will be
made on Oct. 19.
It was the
fifth straight scrub of the launch since July. Three attempts to launch MetOp-A
aboard a new version of Russia's venerable Soyuz rocket were scrapped that
month because of sensor false alarms on the new, all-digital network
installed at the launch installation and the rocket.
Launch
officials spent three months testing the ground installation and its
connections to the modified Soyuz, called the Soyuz 2-1a [image],
but an Oct. 17 attempt was aborted
one minute and 10 seconds before launch when a ground sensor signaled low
pressure in the rocket's upper-stage fuel tank.
Officials
from Starsem, the French-Russian company that manages Soyuz commercial
launches, said Oct. 18 that the sensor warning was erroneous; there had been no
problem with the upper stage's fuel pressure.
This new,
digital version of Soyuz was first tested at northern Russia's Plesetsk
Cosmodrome in November 2004 and worked without incident. The same system is
being used for the first time at the Baikonur site for the Metop-1 launch.
The
4,085-kilogram MetOp-A will be Europe's first polar-orbiting meteorological
satellite and also will inaugurate a long-term cooperation with U.S. civil and
military authorities on weather monitoring. The U.S. National Oceanic and
Atmospheric Administration (NOAA) and the U.S. Defense Department are partners
in the future U.S. polar-orbiting weather satellite system and are sharing
responsibility for a trans-Atlantic polar-orbiting system with Europe's EUMETSAT
organization, headquartered here.
Three
identical MetOp satellites are being built by a large contracting team led by
Astrium of Europe. They will be launched at four-year intervals. Each
carries 11 observing instruments.
The MetOp program,
financed principally by EUMETSAT with a 25 percent contribution by the European
Space Agency, is budgeted at 2.4 billion euros ($3
billion).
