Thank you Nestor for this information
May be you can add that we used  the proposed CCSDS DTN ION to support the Meteron Operations involving Marshal in Huntsville (Alabama) and voice and video were provided using the CCSDS standards via JSC (Houston) and Col-CC (Munich).
Best Regards

Dear MO-ers,

We have just finished successfully the ESA METERON OPSCOM-2 experiment. During the experiment ESA astronaut Alex Gerst "drove" from the ISS the European Ground Prototype Rover (also called Eurobot) on the ground at ESTEC, deployed and stowed its robotic arm and took images.
On the ground the METERON operation teams at ESOC, BUSOC and ESTEC monitored the operations and performed coordinated joint commanding, using the METERON Operations Environment (MOE), deployed in three geographically separated centres.

Beside being a milestone for the METERON project and for Robotic Operations, today's successful OPSCOM-2 experiment is also a milestone for our CCSDS MO Services.

MOE external interfaces have been based on MO services, including standard MO M&C services (e.g. Action, Activity and Parameter Services) as well as proprietary precursor MO robotic services (e.g. Motion Control, Imaging, Manipulation, Command Authority Coordination and File Management Services).
The same MO services were also deployed on the METERON laptop on the ISS as part of the software used by Alex to control the rover.

That is why with todays operations, we can say MO services concept has been validated operationally over the space to ground link.

At implementation level, the METERON Robotic Services, did not use the MAL APIs but have been implemented as web services. The implementation was however based to a large extent on the MAL, COM and MO service specs. The messages were encoded in binary (FastInfoset encoding) and transferred over DTN.

One particular aspect, which may be worth mentioning is that the deployment architecture incorporated the concept of service proxy and the PUB-SUB pattern was adopted over the space link and on the ground successfully. Also we demonstrated that the exact same services were consumed at run-time via two different transport protocols (with two different encodings) on the ground and over the space link.

So, I guess now we can all say the MO Services concept is space qualified and I trust this will help in increasing the TRL.

Please do not hesitate to contact me, if you wish any detailed information.

Kind Regards
