Terraformed Pluto

[PlutonianEmpire]

I had no idea where to go in this forum to share screenshots for bragging rights, so I posted here.

Hi, my name is Eugene. I have been flying celestia for about a year now, and it's the best!

I have created many fictional worlds, most of which may never see the public eye. Here, I have terraformed my favorite planet, Pluto.

Eugene,

The Celestia Forum's home page, at http://www.shatters.net/forum/, tries to describe the purpose of each of the individual forums.

The "Purgatory" forum is for topics that are completely irrelevant to Celestia and probably shouldn't have been posted on the forum at all. Your posting certainly doesn't belong there!

I think the best place for your post is the User's forum, so I'll move it there.

I really like your Terraformed Pluto; and you know, with advanced technology, there might even be a way of doing it. The hydrogen, deuterium and helium 3 in the water of this world and it's moon could sustain a civilisation for hundreds of thousands of years, if not millions;

terraforming Pluto might be a slightly wasteful way of achieving a colony on that planet, but you could perhaps surround it with fusion driven lamps to warm the planet and to grow crops... if you imported fusable elements from elsewhere in the Kuiper Belt you could sustain this civilisation almost indefinitely.

Personally in this case I would surround it with a silver membrane, to cut down on energy loss;

alternately you could warm this little world with a high powered beam of light transmitted from near the Sun; if the beam was powerful and focussed well enough, Earth-like temperatures could be achieved here (and on practically every object in the Solar System).

Would Pluto have enough mass to hold onto an atmosphere? I doubt that part. It seems for small worlds to have atmospheres they must be very very cold as in Titan's case. I'm still learning about this area myself so I'm not all entirely sure the mass requirements to hang onto oxygen and other gasses.

Oops I made that post. I also want to add....

Sure Pluto might have an atmoshpere now but thats because as a I believe it, it is because its very cold there. Now if you warmed it up to an Earth like temperature I think all that gas would just leave since Pluto doesn't have a lot of mass. Oh and by the way, realistic or not I like your terraformed Pluto :p.

A technology that's able to warm Pluto to the temperature of liquid water surely wouldn't have any trouble surrounding it with something to hold in a breathable atmosphere

Hi, I'm back. I recently uploaded terrraformed pluto to the motherlode, so everyone can see it in 3d. I made some changes since the last post, so here's the new terraformed pluto:

What's the deal with the negative day length I can see in your screenshot? You seem to have reversed Pluto's rotation period, which is screwing with Celestia's handling of time units. (I'm guessing the parser uses seconds to display all RotationPeriods less than some cut-off value, and your negative number is therefore falling into an inappropriate bin for its magnitude.)

I remember learning that Pluto spun retrograde, and in celestia, it is seen as a forward spinning planet. I felt it was inaccurate to portray it that way, so i reversed the rotation, altered the axis, and adjusted charon's orbit, based on the info from my astronomy program, Redshift 3. The original data is still in the .ssc file, it just has a # behind it.

Prepere for the Coming of the Plutonian Empire!!!!

OK, I am on the way...

What is that supposed to mean?

It spins retrograde only because it's tilted at more than 90 degrees (same goes for Venus and Uranus). It's still spinning in the "normal" direction, compared to all the other planets, but because the tilt is > 90 degrees it looks like it's spinning in the other direction if viewed from above the orbital plane.

So if you keep the tilt as it is, it'll still be retrograde.

Pluto rotates correctly in Celestia, in a retrograde direction, which you can easily check by noticing that the north rotation pole is correctly aligned to point south of the ecliptic. Charon's orbit is also correctly aligned, and Charon is properly positioned in its orbit. You'll find, for instance, that the various mutual eclipses of the late 1980s are perfectly reproduced in Celestia, using the distribution ssc. If it's accuracy you want, you should stick with the original data - any differences you've found between Celestia's data and your other astronomy programs is because of differing coordinate systems, not an error in Celestia.

While your terraformed pluto is very interesting, it is totally non-sensical. Pluto is much to light a body to hold such an atmosphere to sustain life.

[PlutonianEmpire]

Celestia users have every right to make up fantasy worlds. If you don't like it, then this forum (or this topic, for that matter) is not for you.

EDIT: This was directed at the guest who made the post just above this one.

I have returned Pluto and Charon to the original data provided by Celestia. To offset that, I rotated the maps 180 degrees. I will upload the modified Terraformed Pluto to the motherlode hopefully soon.

I also made a very realistic map of the present day Pluto. I'll upload that soon as well. Hopefully, it'll be the new Default Texures for Pluto.

Eugene,

Would very much like to see the realistic version of Pluto
that you're working on...

Can I ask though, where you're finding the images? Have we
another spacecraft nearby that I don't know about?

Are there datasets stuffed away in a drawer somewhere that
someone has overlooked?

Thanks, Bob

Hehe. No, I'm getting the images/maps from various celestia addons from the Internet.

Eh... What are you referring to, exactly?

Oh, you know what a mess some scientists filing systems are
don't you?

I just wondered if someone maybe found an old pile of images
that had been tucked away for safe-keeping, and then had
been forgotten about.

Was just curious.

Thanks, Bob

I'll upload my Pluto textures tonight.
