Johns NASSAC First Flight using DGII post has been haunting my mind for the past week. Why?
Well because it was done in real time.

How many of you have taken the time, the days, to fly a full mission in real time?

I feel as if I haven't touch the experience John has. Until I fly a mission in real time I wonder how
much of Orbiter I am missing. I truly believe that there is a whole dimension to space flight that I
have been neglecting by using compressed time. I am simple cutting it out. Hey I can do it all in a
hour or two, so I have. Now I feel I need not cheat on time for at least one flight.

Now what? It's not that easy you know. I mean real time flight takes commitment. Am I to sit next
to my computer for a full day or two. I find this practically impossible. At least John had a good
cause to it for. So I decide I would do it, but only be there for the neccessary times. Live life as
normal as possible letting the sim run unattended while I work and sleep. Still this requires a
dedicated computer for this time. My family would surley revolt.

In the mean time I think I'll fly real time with gaps. I'll have to do a series of saves picking up
where I left off. Boy that will take even longer.

Um...I'll be sure to let you know if I come up with a solution. And I'll certainly post if I ever do fly in
real time.

Hi Gene,

Thanks so much for you response to our first NASSAC mission. My goal has been to make the
experience as real as possible. The thinking is that the more real and challenging it appears then
perhaps it would appeal to the older teens as well as juniors.

I understand the problems you are facing with flying  a real time mission. Before flying real time I
had to set up a scenario that would fit within the 25-30 hour window. To do a real time flight
however requiers more than just one individual on the flight to make it realistic. I used the time in
between Orbital burns and RINC adjustments to teach both the flight crew and those watching via
Mission control about the procedure and the reasons for the upcoming burn. The truth is I ran out
of time. In the evening we showed two videos that were space related. In addition the kids had a
list of 25 questions that they had to answer. They needed to work as a team to get all the
answers.  But it was the length of time and the seperation from the rest of those that were
involved that gave it that added dimension of realism. All communication was by Com1 or Com2.
After doing our first real time mission, anyting else will not be as satisfying. True it takes a lot of
preperation. I worked over a year to setup the system to involve as many as I could. It was all
worth it. Now, both parent and child are asking when we could do the next mission? I am shooting
for November or December for the next mission. This time we are going to let the junior and teen
girls go. I will stay behind on this one and work remotley to control things and direct the flight. It
will probally be the same flight with a different twist to it.


We are talking about a mission to the Moon and Mars. We will do this in real time with large gaps
in between.  Or maybe will will break for the evening let the crew on board and do a warp
command on the time.  We will have intermediate goals and end the sessions after the prime goal
is met. As I think about it there are many ways to approach the scenario.  It may look something
like this.
1. Launch and docking with ISS to refuel and Transitional orbital burn to target.
2. Orbital corrections along the way will be carried out by mission control
3. The crew and Mission Control wll gather for phase two of  the mission, Orbital insertion, docking
with an orbital space station, landing on the Moon or planet.
4. Return to earth, launch, orbital transition burn,
5. Orbital corrections along the way will be carried out by mission control for the return trip.
6. Regather the team forOrbital insertion &  docking with the ISS again and then returning to earth
and landing at KFC.

The biggest problem is training others to do their part. This requiers the greatest amount of time.
Kids need to understand it if they are going to stay interested. I am always looking for help and
funds.

I hope to make the simulator available for school groups to use. I would like to challenge them to
work together to assemble a mission and then carry it out. The science and the math lessons
learned along the way could be tremendous.

In our first mission we constantly did ctrl-s to backup the mission in case the computer went down.
We had two occassion in two days to do just that. For the most part I reloaded Orbiter and
pickedup almost exatcly were we left off. It was hardly noticed by those watching.

In doing real time missions it be would nice to have an auto save feature that would back up your
scenario every 5 minutes or so.

There are a lot of challenges but we learned a lot from our first mission just as NASA learns from
every mission they do. The bottom line is that the kids love it and learn a lot from the experience.

If you ever get up to Berlin, MD stop by and say hello. NASSAC 519 South Main Street Berlin MD
21811

With High regards;
John

What John wrote was impressive. I do not know if the software he described is available to all?

I know there is no way I could do a real time mission with all of the real life interuptions that come
and go unless there was a real reason, like this one, to do so.

I would suggest taking your astronaut food with you. Chips, soda etc. LOL

Well it looks like it is a matter of time at any rate.

How did the terra system work out for you? I was kinda holding back to see what you thought.

Hot Dog,

With my slow dial-up connection I had to wait almost a day to get the full download of terra
system. It certainly was worth it though. I spent much of my waiting time trying to fiqure out
Duncans new TransX3.  Anyway the Terra System is fabulous. Thanks much. Can't wait for the
upgrades for it.

For those who haven't downloaded it yet, do so, you won't be disapointed. See my full review at
my website.
