Okay, this is the state:

Why the Odyssey is on the surface of the Sun? :facepalm:
Is that something with my computer, or what?

We've completed a very nerve-racking crew and cargo transfer:p
Well done to the crews of both ships:cheers:
Next stop, Mercury:)

Discovery is on her way to Mercury:cheers:
That was a very rough month or so:p We faced a lot more challenges than the Odyssey crew did, and still everyone did a terrific job:thumbup:

We wish a safe journey to the crew of Discovery!:hello:

I apologize for not being present, matters outside of my control interfered.

That mission was a little rocky, but given the challenges we ran into, everyone did a fantastic job:thumbup:

Any idea what happened?

No problem;)
The Discovery team is in your hands from here on out:thumbup:

I just removed the SAS, as astrosammy said...

And here is the Odyssey, after some Mid-Course Corrections:

I need to do another MCC, but I'll do it some weeks before the orbit insertion, don't worry...
I just can't perform all the corrections in one time, so I need to do it later in the mission...

For future reference, everyone please remember to replace the MJD decimal point with a "_" in the file name. Two dots in a file name can cause problems.

After a smooth cargo transfer, the airlock between Chronus and Discovery couldn't be opened. Therfore an emergency EVA was schedulded, to transfer the Crew of the Discovery to their ship. The failure was later discovered as a faulty pressurization valve.
You know, the interesting thing is, something like that could very well have happened in real life.

So far, we have faced down some of the challenges of conducting a real-life interplanetary mission: the logistics, the timing, the coordination of a lot of people in different places operating on different schedules. Even some of the glitches in Orbiter have some similarity to the mechanical failures that happen in real spacecraft--certainly they can have the same consequences! And most of all, we've had to rely on some deadly serious team-work.

I remember being in the pilot's seat of Chronus's first mission back in March, in the earliest days of the project. Everybody was in chat and ready (we didn't have Twitch yet:lol:), so I hit the switches to fire up the APU and started taxiing to the runway. I got maybe ten feet before hearing a loud bang, and the ship was all the sudden spinning like mad through space, with a warning on the screen that my crew had all suffocated. It turned out that I had forgotten to raise the crew elevator before taxiing. I wrote it off as an Orbiter glitch and started the mission over. After all, if that had happened for real, the ship would probably have been severely damaged and the mission scrubbed, but certainly there wouldn't have been any deaths. But by all rights, we could have accepted it, and said that all of the A-Crew except Lydia died in a mysterious explosion. Mysterious explosions happen in space programs--think of Apollo 1, and Challenger! But I felt that after all that build-up and anticipation, I'd be a real :censored: to simply say "Sorry, guys, we all died" and end the project there. So I let that one go and restarted, figuring it was Orbiter's problem and not ours.

It haunts me to this day:(

There are also many problems in real spaceflight that we have not had to deal with. The psychological pressure of spending a few weeks--let alone a year!--crammed with a few other guys in a small metal tube where an uncountable number of things could go wrong, and anyone or everyone could bear some level of blame, could easily drive astronauts bonkers. Even the very successful Mars 500 experiment could not fully simulate the extent of that problem.

And of course, there are the nasty health issues of long periods in zero-g, radiation (especially on Mercury!), micrometeorites, and all the other things that make good Hollywood drama:p

I'd say that everyone involved in the Iron Hill Project has proven that they have at least some of the Right Stuff (though not all of it by any stretch:p)

Very true. I would suggest that you and the rest of the Deep 6 project team try to document some of the experiences you have in doing it. Orbiter may not be the highest end mission simulator on Earth, but even a project like this provides interesting data on how Interplanetary missions will work in the future, psychologically & logistically.

On the topic of the right stuff,

Okay, I've noticed some strange things that are very likely connected to the problems we've been having with Chronus--ISS and Mir are in wacky orbits (ApA in the 1200 km area), Luna-01B is in a roughly 1700 km orbit around the Moon, and MESSENGER is on a hyperbolic path over 3 million kilometers from Mercury.

And that's without SAS being in the file at all:huh:

Any thoughts?

Well, we don't need ISS, Mir and Luna. We can put MESSENGER back and "shut down" the first three if they have problems.

I tend to see that as a "last resort" measure...I'll do it if I have to, but first I'm going to try splicing them in from some older states.

Okay, that didn't work :(
I'm really stumped on this one:shrug:
But I did find out that some of the strange happenings can be traced all the way back to the beginning of the project in March of 2012.

Not really about fix this, but about what to do after fixing: we can use [ame="http://www.orbithangar.com/searchid.php?ID=4331"]Real Time Update[/ame]. The advantage is we won't need ScnEditor to update time anymore AND turns the simulation more accurate.

Good idea, but for a more accurate simulation update, you need to change "ACCEL" value to TRUE, it will speed up the time instead of starting directly in the right MJD.

Yes it works.
RTU gets the System MJD to put in the scenario while saving it. Then when reloading it, it gets the new SysMJD, makes the difference with the old one, and do the update.

So it should work (and works for me) with the current state.

Yes! Good for lagrangian stations, to simulate orbital perturbations in real time and to simulate consumables.

Here is the current state. I made another correction, now the trajectory is almost perfect. I did this correction some hours ago, but my connection didn't allowed me to post the file in the forum :facepalm: .
