Swimming Pools...On The MOOOOON!

I was putting together ideas for a new scifi story and one element kind of threw me...how would open water, like say in a swimming pool, act on the Moon? I read up a lot on different science subjects, but I'm no expert on fluid dynamics or low gravity physics. So I posed the question to Reddit's Scifi Board, and got a lot of great responses.

Some interesting conclusions from the responses, summarized here:

-- Without so much gravity pulling on the water, intermolecular attraction plays a bigger role in how the water behaves. For example, surface tension would create a meniscus (basically a broad hump of water) in the middle of the pool. It may be possible to over fill the pool by an inch or so, as the meniscus would 'suck' the excess water into the middle of the pool.

-- When you got out of the water, much more water would cling to you. As one commenter pointed out, it could be a liter worth of the stuff. So just toweling off might not be enough if you bathed or went for a swim--you may need to scrape off the excess water first.

-- Waves would propagate much higher than Earth. You cannonball into a lunar swimming pool, instead of foot-tall waves, you'd create a mini tsunami with maybe 5-6 foot waves. Splash fights could become truly epic. It seems to me that the sides of swimming pools would actually have to be high, sloping, and segmented it order to break up possible high rogue waves and prevent a lot of spillover.

-- The waves and water motion would move slower than they would on Earth, though, seeming to go in slow motion. Just as astronauts hopping on the moon seem to move slowly because they 'float' downward, it would be the same with the water motion because of the lesser gravity.

-- Stunt swimming and diving could also become truly epic,as you'd be able to swim and jump and dive in the water like a dolphin.

Just some interesting stuff to contemplate. Maybe someday our children or grandchildren or great grandchildren will actually see some of this for real, when they vacation on colonies on the Moon...

600 Million Tons Of Lunar Ice

Recent data analysis from India's Chandrayaan-1 probe has confirmed the presence of water ice in craters near the Moon's poles. The full article can be found HERE on NASA's main website.

If their estimation techniques are correct, the scientists estimate there being at least 600 million metric tons of water ice in the lunar polar region. That is of course spectacularly good news for future bases, and further into the future, colonies, on Earth's natural satellite. That much ice, combined with careful recycling and management, could both provides water, oxygen, and rocket fuel for manned endeavors there for many decades.

And of course, ironically, this comes on the heels of the Obama administration killing off any prospect for returning to the Moon in the short term. We can now see much more clearly how feasible a long-term manned presence on the Moon can be, only to have the prospect of establishing such an outpost pushed out of our reach to at least until the mid-2020s. Its not that the other projects the new administration want to pursue aren't worth doing, but actually opening up a brand new world to humanity would seem to be the better choice of a long range goal, in my opinion.

Oh well. One thing I should suggest to NASA (not that i think anyone there will actually read this): as long as you're underwriting various private space endeavors and X-prize like contests, how about underwriting a sample-return mission for the lunar ice? We can learn definitively what's in it and probably how it was formed. plus the mission may just help to scout out a possible future manned landing site...

Re-Envisioning Space:1999

A number of sites and forums observed that yesterday, September 13, 2009 was the ten year anniversary of the nuclear waste repository on the Moon detonating, blasting Earth's only natural satellite out of orbit and sending it careening deep into interstellar space. The fate of the 311 personnel trapped on Moonbase Alpha remains unknown.

Or rather, it would have been, if we lived in the universe of
Space:1999, a quirky but fondly-remembered science fiction series from the mid-1970s. I watched it religiously as a kid, but I have to admit it did not age as well as Star Trek from a few years earlier. There were some ambitious scripts and ideas--I think it was the first on-screen work of science fiction to feature a wormhole in one episode, for example--but the shoestring budget, sometimes wooden acting, and the gonzo approach to a lot of its scripts tended to detract from that.

But the basic idea--a ragtag band of reluctant humans riding a rogue world into the vast unknown of the universe--is still a slambang one, rife with tons of story potential. It just needed a better execution. In this age of restarts and re-envisionings, I'm surprised Space:1999 hasn't been picked up for one yet.

So how would one go about reworking it to make it more palatable? Let's call our new version Space: 2099 and set it in that year. That gives us nine decades of history and technology to play around with.

We can have the same set up: a large international base on the moon, named Alpha. But since its set much farther in the future, we can make it bigger than the original Space:1999 Moonbase. The 2099 Moonbase has over a thousand personnel, and there are other facilities around the moon as well, smaller bases, observatories, and most importantly, strip-mining operations extracting Helium-3 for power and other vital elements from the lunar surface.

Five years before the series opens, astronauts discover an eons-old facility of obvious alien origins buried deep on the farside of the Moon. The facility holds a number of vast mysterious machines of unknowable purpose. And, much to their horror and delight, human explorers also discover vast quantities of antimatter buried even further into the moon beneath it.

On September 13th, 2099, investigations into the alien machines go horribly wrong. A vast explosion shakes the entire satellite. Only there is very little destruction--the antimatter functioned as an immense Explosive Power Generator to feed a gargantuan wormhole generator. Thus, we can have a parallel to the original series of a massive explosion hurtling the Moon away from Earth, but with a slightly more logical way to get it to the interstellar adventure part quickly.

The Moon arrives in a new solar system through the temporary wormhole, entering into orbit around a gas giant just as the gateway back to earth collapses. Of course, the new star system is an odd one, seemingly created artificially, with dozens of life-bearing worlds from around the galaxy, and hundreds of moons and asteroids, giving the crew plenty of mysteries to unravel and new worlds to explore. Who created the artificial star system? Was it the same people who created the device that brought them there? What are the other inhabitants of the system like? Are they trapped there like the Alphans are? And can they ever find a way to return to Earth, if they can even find out where it is?

And in this age of Lost and Battlestar Galactica, we can have a lot of good, heavily-character-oriented stories as they unravel these huge interconnected mysteries. A lot of the characters in the original were a bit bland; it would be nice to see things spiced up with the updated version. If drek like Moonfall and Defying Gravity can get greenlighted, how about another quality scifi show with a proven, nerd-pleasing premise?

Some caveats, though: Don't mess with the Eagles, the all-purpose modular spacecraft used in the original series (and pictured above.) In my opinion, they are among the best designed fictional spacecraft ever created. Even the shows worst detractors liked the Eagles' sleekness, believability, and raw functionality. They would be as iconic to the show as the Enterprise would be to Star Trek.

And also, keep the beginning sequence, or at least the spirit of it. It started with these majestic instrumentals, showing the lead actors. But then it cut to an Eagle plummeting and exploding on the Lunar surface, segueing into a fast-paced funky theme that sticks in my head to this day. A quick montage of teaser scenes followed in quick succession, ending with SEPTEMBER! 13! 1999! flashing by and showing the moon breaking out of orbit. If the rest of the series had been as cool as its opening, it might have had a much longer life.

Anyway, that's just some ideas. I doubt we'll ever see a real Space:1999 remake, but its fun to play around with the concept anyway.
