Not to rain on your parade, but this is extremely unlikely to happen. For past missions the EDL data were released to PDS years after the landing. Even the MSL landing simulation on Eyes wasn't based on realtime data AFAIK.


He said "so hopefully we get real time EDL data just like we did on Phoenix"; assuming that people officially involved in the uploading EDL firmware will receive realtime telemetry by sure, I deduced he was talking abouth something like publishing realtime telemetries. Did it happen for Phenix?
Anyway, telemetries of "just" surface operations like initially happened for Philae would be good too. :-) (I followed in realtime the depletion of the battery... until DLR cut the feed :-( )

No.

Sorry to create confusion. By real time telemetry I mean that we on the ops team would see real time UHF telemetered EDL data through the Marco small sats. On Phoenix we got a real time link through Odyssey (it was very cool to see the real time data, I remember thinking, wow I'm seeing data from a spacecraft on a parachute over Mars!). If the Marco links do not work we will still get the open loop recording of the UHF data stream from MRO (the program decided to record the open loop stream, then if there were any issues the full transmitted stream would be available for data extraction). That will downlink later in the day for review by the ops team. Of course with a successful landing we will also get the playback of the data in the first Odyssey pass about 5 1/2 hours after landing, so the MRO data is primarily for anomaly review.

Of course the real time data is not something that will be available outside of the project. When and how they will publish that data is not something I know anything about. Sorry to provide a false hope of seeing this data on NASA TV or other sources. Any animation you see of EDL will be purely open loop with estimated timelines from prior to EDL. Assuming we do get the UHF data in real time there should still be a running status of the EDL progress over NASA TV (as you are used to with Phoneix and MSL). If we do not get the link from Marco we get a few blips on the UHF direct to Earth transmit (too low a signal to see data, just get the open loop signal strength) in EDL that provide progress such as on the parachute and landing. Certainly critical data, but not the same as receiving real time data.

Things looking good less than 2 weeks to EDL!
