I was snooping around on Google images and i found this::rofl:
I think they're trying to say this is a real NASA proposal :lol:
Yep its true.... Captain Kitten flew the craft
:rofl::rofl::rofl:

Here's where the picture is located: http://lunarnetworks.blogspot.com/2010/10/destination-moon.html
These Lunar Pioneer guys really need to say it's the DGIV add-on for Orbiter.

What would be the point in that? They aren't turning a profit with it and aren't claiming it's theirs.

They claim the picture is "From Lunar Networks: Lunar Pioneer Online", which just links to the picture itself.

Well, today marks a whole year on O-F for me.
Here's to another one.

Passed the Turing Test
Lost a pet for the first time tonight. Had him as a kitten and for about 11 years. I miss him already, like a family member, but I'm glad he at least passed away with all of us present.
Is this right?
I want to prove him wrong.
So it's not Earth at all.
To get 5 times the surface area, your radius has to be √(5) (or about 2.2361) times that of the Earth (area of a Sphere is A=4πr²).
Let us call this new radius r'.
That doesn't sound like much until you remember that the formula for the volume of a sphere is V=4*⅓*π*r³.
Because the volume is a third power function of radius, not a second, the volume is going to grow faster than the surface area it follows that our new volume is V=4*⅓*π*r'³, which is about 11.2 times the volume of the original.
This wouldn't be a problem, but the force of gravity is linearly related to the gravitational constant G and the product of the masses of the two objects and inversely proportional to the square of the distance between the centers of the objects.
If we work from the surface of the larger object, and assume that the objects are of sufficiently different size (say a planet is the larger object, and anything not mega-meter scale is the smaller one), the distance between the centers can be approximated by the radius of the larger object (which we had defined earlier as r). The formula is F=G(mₑ*mₓ)/(r²) where mₑ is the mass of the planet, mₓ is the mass of the smaller object, G is the gravitational constant (Thanks Sir Issac!).
The Mass of the planet is linearly dependent on it's volume and it's density. m=vρ if the density (ρ) is the same, then the increase in mass is proportional to the increase in volume (or, 5^(3/2))Going forward, if we call the mass of the new planet mᵦ we find that mᵦ is 5^(3/2) times mₑ. Plugging this into the Gravity equation (along with substitution of r' for r) we find that the force of gravity on your world is going to be 5^½ times that of Earth (~2.24 times that of Earth - the acceleration due to gravity is now greater than 20 meters per second per second). Everything changes.

I don't really even use the PSN. Besides, I prefer to buy physical copies of games. That's right kids, you can actually buy software in stores on cartridges.
With regards to the DG-IV picture...
This is the second time I've heard of something like this happen- remember there was that ad (from a magazine or something) with the Deltaglider Mk 4 virtual cockpit?
I know they're not trying to make money, but they are showing an idea without giving credit. This is plagiarism. It's like using a work of art in a picture, and not giving the artist credit. It really dose not matter whether they are claiming originality. It's morally wrong. If it was a model I made, then I can tell you I'd be really upset.
The probe is unhappy with all this.

Don't remember exactly. I saw it a while ago somewhere on the forum. There was this ad with a Delta Glider cockpit.

One of my favorites. Sounds better in a high quality flac file, but whatever.

In other news: you guys in the North should look out for aurora in the weekend (or so): the Sun has just erupted, with an X5 class solar flare just happened two hours ago! :blink:

Hey everyone! You're not going to believe it! I found this cool space-flight simulator! It's free and has a ton of addon content. Check it out!
