I have just a challenge for you DGIV veterans, try orbiting the earth BUT set the launch autopilot so that you orbit the
earth at 50 kilometers, thats right 50! Try accellirating to 17,500 mph to make the orbit, just don't fry yourself.

impossible because the dynamic pressure will be to great and you would need constant thrust

I agree with tl8roy. It would not be realistic.

Now here is a better challenge- do an Orbit insert to the moon that puts you less than 1km above the surface, and
circularize your orbit to a 0.00000 Ecc so that one full trip in orbit around the moon is less than 1 km above the
surface. I will say, depending on how quickly you get to the moon from the Earth, there is going to be a big pucker
factor on that insert.

Not realistic one bit. That is more like an atmospheric flight than an orbit.

yeah I guess your right, how about speeding up with turbo until you run out of fuel?(In space fromearth orbit)

ha! Simonpro i did it lower than you! :blbl:

less than 100 (Ultra Low Lunar Orbit)! 8o!

maybe you used that tin can (Shuttle-PB) as tg said, well i did this with a DG

Nope, I did it in the DG. If you really want a competition you can try beating the 1.6m orbit I managed a while back. There's
a picture on the main orbiter forum of it somewhere.

And where precisely would you reenter, and why? The gas giant's don't have a surface (at least in Orbiter. For real, we don't
know). If you reentered, any real ship would be crushed by the gravity, and even if it was not, you would never get off the
"surface" again.

How about this. Put yourself on a trajectory that has you going at or over 100,000k towards the body (Vespucci D can
accomplish this). Release your DGIV- 24 hours out from interface at Jupiter. Using nothing but Jupiter's atmosphere,
aerobrake the DGIV until you reach a PeA of between 1 and 2 M, and burn to a circularized orbit. -No time limit.

This will test your aerobraking skills. Can you circularize without going too deep into the atmosphere? Also, at this high
rate of speed can you slow down enough not to be slung out like a rag doll into space. The first interface will be the
toughest. The rest will be cake.

It's true what you said about the gas giants, and yes the surface on them is unrealistic, but as surprising as it
sounds, it is prossible that, on Neptune, you can survive a 48,500, mph re-entry until about more or less 105
kilometers, you just need to keep speed low like 15,000 mph.

I thought that gas giants had a solid "core"... I mean, all that gas has to be floating around something, right?

It's possible, but then all that gas might just be only gas simply held together by gravity.

just like the licks required to get to the core of a tootsie pop... "the world may never know" :)

I'm solid with a gaseous core...Just ask my wife! :badsmile:

The "theory" is that below the atmosphere is an ocean of liquid hydrogen or helium and a core of metallic hydrogen. Now, it
isn't how cold the planet is that makes the hydrogen liquid or metallic, rather the pressure of the gravity. And since all of
those atoms are being pressed together, the surface is rather hot.

Just think of it this way. A gas giant is really somewhere between a planet like Earth and a star. I am becoming more of the
mindset that this type of "planet" really falls more to the "star" category, but we just had this argument a year ago with
very smart people who do astronomy for a living. I can't imagine my "input" means a hill of beans.

I have a better challenge for you.

Fly from Cape Caņaveral to Habana in a suborbital flight.
Fuel tanks are full before you take off.  You will use the DGIV setting that consumes more fuel and tank setting that
has more fuel.  You will carry 2 cargo containers and 4 passengers.

The goal is to land safely at Habana as fast as possible, taking as little as possible from take off to landing (complete
stop).  And of course you need a safe landing.

You may use whatever MFD you want.
No chicken mode is allowed.

If you want to increase your selfesteem, try this suborbital challenge, compete against yourself.
Keep a log of each flight and you will see yourself enjoying a lot.
The first few times you will burn or crash the ship.  It always happens when you do that for the first time.

you know, I've never tried to orbit and land on the sun before, why not try that, before you say "that's super
unrealistic", think about it, THINK ABOUT IT!
