Phoenix Mars Landing Thread

[DaveS]

A lot of the participants in discussions there have a large bias towards trusting opinions/solutions from NASA at the expense of others. I just don't think it's very healthy. I'm not in any way complaining about the lack of coverage of the ISS partners though, I don't look for, or expect, any from them.

Not exactly! Ares 1 and Ares V is heavily questioned and ESAS is under a full blown attack as well and that includes it's main author, Mike Griffin. And there's not much love for Scott "Doc" Horowitz either!

So, not much love for Constellation according to NASA there! And NASA doesn't really deserve much credit for getting the shuttles up/down. That credit goes to the contractors/sub-contractors(USA, Lockheed Martin, ATK etc).

NASA really only provide high-level management. The only NASA employees in the Shuttle FCR in the MCC during missions is the MOD reps, Flight Directors and CapComs, a grand total of 6 persons! The rest of the flight control team is USA employees!

Good luck Phoenix!

The title says it all, here give updates on the Mars Landing Pheonix which is to land today. (And for some reason Nasaspaceflights forms down.:compbash2

Pheonix? Phoenix! I corrected the topic title, if you don't mind

Can somebody possible create a scenario with the correct data to simulate the EDL "real time"? With a mark time as when to start the scenario running. Say entry minus 2 hours?

Just the XYZ position lines and the mark time will be sufficient. Thanks in advance.

What is ET for Landing?

What is ET for Landing?

7:52:52 pm EDT.

 

[silent_protagonist]

7:52:52 pm EDT.

Is that real time, or communication delayed, when-we-know-about-it time? (Just because I like to nitpick )

BTW if anybody gets the Science Channel they're going to be running live coverage starting at 19:00 EDT (23:00 GMT).

At this point in Time Phoenix is accelerating, Mars is pulling her in. This is expected.
This happens every time on Orbiter when your nearing Mars.

Should be getting Solar Pannel Sep here soon.

If you will be following the Phoenix landing using Orbiter with Brian Jones' add-on spacecraft the time to start the simulation is 6:24 PM EDT.

The simulation takes 1 hour and 14 minutes to run from its starting point 12,944 km above Mars to the actual landing. That will put you on Mars at 7:38 PM EDT. The signal from Phoenix will reach Earth 15 minutes later at 7:53 PM.

Not for while, still some 90 or so minutes away from Cruise Stage sep.

 

[Missioncmdr]

Should be getting Solar Pannel Sep here soon.

What? That is not supposed to happen until about seven minutes before entry.

 

[Missioncmdr]

NASA TV coverage starting.

 

[Kyle]

My Bad, Sorry for false info, thanks for correcting.

 

[Kyle]

NASA TV Coverage is on.

 

[DaveS]

MRO and Odyssey is GO for EDL COMM SUPPORT. Instruments in EDL configuration.

 

[DaveS]

ESA MEX is GO for EDL COMM SUPPORT.

Using Brian's updated Phoenix Addon and the new scenario. I find myself running about 20 minutes early in UT, with touchdown occuring at 23:38 UT. Anyone else finding this?

The numbers here on Earth are delayed because of the time it takes radio transmissions to reach Earth.

That's correct. Remember, all the times stated are Earth Received Time or ERT, which is 15 minutes behind the actual events. That's how long it takes for the signals to travel from Mars to Earth. So 2338 UT is the correct touchdown time.
