As already mentioned previously, 2 of its 3 gyros are show= ing an abnormal behavior, very likely due to their ageing during 9 years in= the difficult radiation environment experienced at 1336km orbit. As 2 gyros out of 3 are required to ensure nominal attitude control, no mis= sion recovery has been possible for the moment, nor is planned in the futur= e days : actions for recovery are however undergoing and we are still optim= istic about resuming Jason-2 data production in the future. A Joint Steering Group has been called on June 20th in order to discuss fut= ure plans on Jason-2. We will of course keep OSTST community informed of the decisions of this JSG Very best regards, Christophe Marechal Jason-2/Jason-3 CNES project manager
