Objet : Jason 2 information from mlast JSG

Dear OSTST,

During the last exceptional JSG held on June 20th, due to the gyro 1 and 2 
status that will need more investigations, the global ageing of the spacecraft, 
and the already existing recommandation from OSTST to move it to a new 
orbit at 1309.5km, it was decided to start the maneuvers to that new orbit
 as soon as reasonably possible.

Maneuvers to that Long Repeat Orbit (LRO) will then start on Monday, July 3rd, 
hoping to reach the LRO by the end of the week (July 8th).

If the spacecraft status is still green, the instruments will be restarted 
on the following week (from July 10th)

CNES will keeping on performing investigations on gyros, in parallel of that 
mission restart.

I will keep you informed of the results of those investigations.

Best regards,

Christophe Marechal
Jason-2/Jason-3 CNES project manager
