Europe has delayed again the flight of its most sophisticated weather and climate satellite - the Metop platform. The spacecraft was set to go into orbit on a Soyuz rocket from Kazakhstan, but the launch countdown was suspended with just seconds left on the clock.
The MetOp-A satellite launch was scrubbed at T-1 second, before the planned 16:28 GMT (12:28 p.m. EDT) lift-off today due to an. as yet. undisclosed problem with its Soyuz ST Fregat launcher.
Following the roll out to the launch pad and erection at the launch tower at the weekend, MetOp is ready for launch at 18:28 CEST tomorrow from the Baikonur Cosmodrome in Kazakhstan. The launch of Europe's first polar-orbiting weather satellite is set to make a major contribution to global weather forecasting and climate monitoring. The roll out to the launch pad and erection of the Soyuz rocket at the launch tower took place on Saturday 14 October. Carried by train, the launcher left the hall where the upper-composite, which comprises the MetOp satellite and the Fregat upper-stage, had been integrated with the third-stage of the launch vehicle. The train slowly pulled its cargo over to the launch pad where the rocket was erected with the help of a huge hydraulic ram. The final countdown rehearsal followed, confirming that the launch will go-ahead tomorrow.
EUMETSAT confirms Tuesday 17 October as the new launch date for MetOp, Europe's first polar-orbiting satellite. MetOp will lift off at 18:28 CEST (16:28 UTC; 22:28 local time) from the Baikonur Cosmodrome, Kazakhstan on a Soyuz/ST launcher.
EUMETSAT has announced that on Saturday 30 September the upper composite (comprising the MetOp spacecraft, the Fregat upper stage and the Soyuz fairing) experienced a slight mechanical shock. It was then decided to interrupt the launch campaign and return the upper composite to the clean room for inspection.
A preliminary review has already indicated that there are no apparent problems, however a full inspection of the spacecraft and the Fregat is considered essential. The fairing will therefore be removed today to allow for visual inspection.
A new launch date could then be announced by Starsem on Wednesday 4 October.
As the launch campaign continues on track, the MetOp satellite has been successfully mated to the Fregat upper-stage.
As both the satellite and the upper-stage engine remain fuelled, the integration is potentially hazardous. Nevertheless, this delicate operation was carried out very smoothly with everything going according to plan.
With the launch of MetOp now set for 7 October at 18:28 CEST, the MetOp satellite is out of storage and preparations for launch are well underway at the Baikonur Cosmodrome in Kazakhstan.
MetOp-A, the first in a new European series of three meteorological operational satellites designed to monitor the Earth’s atmosphere from polar orbit, is now to be launched on Saturday 7 October from Baikonur, Kazakhstan.
It will complement Europe’s already highly successful Meteosat satellites positioned in geostationary orbit and will form the European part of an integrated system to be deployed jointly with the USA to provide better weather and climate information.
The first MetOp satellite is currently at the Baikonur cosmodrome in Kazakhstan. There, it is undergoing final preparations for its 7 October launch onboard a Russian Soyuz ST/Fregat rocket operated by Starsem. Lift-off is scheduled for 18:28 CEST (16:28 GMT).
