“There’s a dirty four letter word. That is, ‘cost’. It costs about $10,000 to put a pound of anything into orbit. It would cost about 20 million dollars for you to take a weekend trip up to the space station. It would cost about a half billion for you to go to the Moon. And for you to go to Mars would probably cost tens of billions of dollars.”

This is nothing new. Dr. Kaku is not saying anything we didn’t know before. But watching The Universe last night got me thinking. Ehhh, that’s not that much. $500 million to get back to the Moon? I got this.

I have an idea! The room lit up with the eco-friendly florecsent light bulb now hovering above my head. Let’s crowdsource it. Sure it’s a lot for the government. They can’t go spending billions of dollars all willy nilly just because I think it’s cool and important. Though they really should. C’mon government.

I’m over-simplifying, but here’s what we’re gonna do. Have the government come up with a budget for getting back to the Moon. Then we’ll take pledges from rich dreamers, SF nerds, and really smart people. You don’t have to give me 2 million dollars. Just pledge it. If we reach our goal, then you give me 2 million dollars. Simple right. I walk into NASA with slicked back hair and a briefcase handcuffed to my wrist with $500 million in it and we go to the Moon. Cutting edge thinking!

This morning, 12 hours later, I happened upon the msnbc homepage and right there in the middle of the page is a link to a story called Billionaires Wanted for Starship Plan. They want to send multi-generational ships on a one-way journey to the stars. A little bit more ambitious than what I had in mind, but it’s the same idea. Get rich people to pay for it. The super wealthy are always concerned with legacy. This is definitely one way for your legacy to live on.

Or one could say Ganymede is George Harrison of the four Galilean moons. She quietly waits in the background with her sparkling channels and her wonderous craters, while John and Paul get all the adoration. Until you realize that, she’ll probably make the best solo record of all of them.

As a testament to it’s beauty, Ganymede was believed to be a star upon initial discovery.

Missions to this gem have been proposed and canceled due to budget cuts (read: Iraqi War) with the next mission tentatively scheduled for 2020. Attention to Ganymede will be at a minimum with Europa being the main focus of that mission, but at least we’ll be able to take a closer look with better tech.

Colonization of the Jovian moons has always held a special place to futurists because of their size (Ganymede has a larger diameter than Mercury) and captured heat from the gas giant. Like Europa, a liquid ocean is believed to flow beneath it’s surface, further adding to the fascination. Ganymede is one of the few celestial bodies in the solar system to have it’s own atmosphere and magnetosphere- two things that make Earth so perfect for life. Though it’s oxygen atmosphere is thin and tenuonous, knowing that a moon can have such things tickles the imagination.

Imagine sitting on a rock where the moon, in this case Jupiter, takes up 80% of the night sky. Walking freely like Superman in a gravity 1/10th that of which you are accustomed to. An artificial and transparent dome above your head to keep in the oxygen/carbon dioxide/nitrogen stew that gives you life. Just protected enough from the radiation your mother planet continuously emminates. Perhaps you’ll take a road trip around the globe. It only takes a couple days in your high-speed tumbler. Thoughts like these make me giddy.

This concludes today’s astronomy class.

First is the experience of zero gravity (0g). Being able to float freely in the air is by most accounts an extraordinary sensation. It’s a power you’ve never possessed. Handicapped people will be able to leave the chair at home. The feeling of weightlessness has been compared to “floating in water without the sensation of water on your skin.” And the “realization of a dream.” You feel like Superman. There is no up or down either. You have complete control (or lack thereof) over direction and movement.

Another reason will be for the extraordinary views. Mostly of Earth, but of Luna and the stars as well. Watching the Earth will be how you spend a lot of your time. Great viewing rooms, several stories high, will be created to enhance the experience. Weather patterns change the Earthscape continuously. You will see the flash of lightning almost every minute. You’ll be able to see the energy of human civilization as you pass through to night. Viewing the blue ball we call home is a humbling experience. You finally realize how small you really are. You finally see your place in the universe. Similar rooms will be scattered about to provide for moon and star viewing as well.

The final reason to go to a space hotel will simply be for the adventure and story. The first people who will buy tickets are the people that have dreamed about going into space their entire lives. It is the thrill of a lifetime. Hopefully the welcome outcome of countless hours spent staring up at the sky and wondering.

But what will we really do when we get there? Along with these viewing rooms and other areas to play in 0g, there will be loads of entertainment. You’ll buckle up and watch shows put on by the entertainment staff. You’ll see live music. Drummers will play upside-down. Theatrical productions will inherently utilize the 0g. New forms of dance will be created. Spectacles you never dreamed possible.

Naturally, there will be a large dining room. However the romance is completely gone when you have to eat your food from a straw. Imagine drinking wine with a straw? And there are safety issues as well. Utensils would float freely around the room. It would be a slight problem if you were eating dinner and a steak knife floated past your head. For these reasons there will be rotating sections which create artificial gravity for the dining room and other areas. Along the side of this room will be large windows to offer additional Earth-viewing while you dine. Music will fill the air.

The bedroom won’t be just the place you retire to. This is where you’ll be able to check out 0g more personally. Brothers and sisters will wrestle all night. Portals will provide more stargazing opportunities. Here you’ll find your 0g toilet. Interior designers will have another dimension to use when creating modular bedrooms for space. Beds can be oriented any which way. One on the ceiling, one on the wall. Sex in space will be a hugely enjoyable activity. The floating beast with two backs. Honeymoons will presumably be a major source of business.

In the future, separate orbital stadiums will be flown in synchronous orbit. You’ll take a taxi over to the stadium where a variety of activities will be available. A zero gravity pool, playground, and new “space sports” are just some of these. 0g adaptations of common sports such as tennis and soccer will quickly arise. In a 0g pool, large “bubbles” of water float in the air. You’ll float in and out of one bubble to the next. Artificial gravity pools will be just as intriguing. In this case, the water will line the sides of a cylinder. Creating a donut of water. Those who seek real adventure will sign up for tethered space walks. Of course, there will also be malls and casinos. What would a vacation be like without bringing back souvenirs? I went to space and all I got was this lousy T-shirt.

So start saving now. This is all coming. The Japanese have just announced that they are planning on creating a space elevator to get stuff to orbit cheaply. They’re actually gonna try to do it! Once cheap space flight becomes available, the sky is no longer the limit.

Space Future is a terrific website and was consulted heavily for this post.
