Yuri Bakhvalov, First Deputy Director General of theKhrunichev Space Centre on behalf of the Russian State Commissionofficially confirmed that the launch of CryoSat ended in a failure dueto an anomaly in the launch sequence and expressed his regret to ESAand all partners involved.

Preliminary analysis of thetelemetry data indicates that the first stage performed nominally. Thesecond stage performed nominally until main engine cut-off was tooccur. Due to a missing command from the onboard flight control systemthe main engine continued to operate until depletion of the remainingfuel.

As a consequence, the separation of the second stage fromupper stage did not occur. Thus, the combined stack of the two stagesand the CryoSat satellite fell into the nominal drop zone north ofGreenland close to the North Pole into high seas with no consequencesto populated areas.

An investigating commission by the RussianState authorities has been established to further analyze the reasonsfor the failure, results are expected within the next weeks. Thiscommission will work in close cooperation with a failure investigationboard consisting of Eurockot, ESA and Khrunichev representatives.

This information is released at the same time by Eurockot and ESA.
