But note that their quality was degraded because of the SHM and the non-nominal att= itude law. - The solar panel / attitude quaternions files were also disseminated but are not significant. Best wishes, Pascale Ferrage De : Marechal Christophe Envoy=E9 : vendredi 12 avril 2019 11:04 =C0 : ostst@jpl.nasa.gov Objet : [EXTERNAL] Jason-3 is back Dear ostst, This morning, on a pass at 07:00UTC (i.e. on cycle 116, pass 246), all JASON-3 core mission instruments were restarted : - POSEIDON at 07:16:24UTC - AMR at 07:18:12UTC - GPSPB at 07:20:01 UTC The first post-SHM mission telemetry will be available around 09 :45UTC.

Our teams are currently investigating the exact reasons of that SHM, in the objective of restarting Jason-3 measurements as soon as possible. We will of course keep you informed of the schedule for mission recovery. Very best regards.
