And yet building a small biosphere on another world would give us invaluable data on how to protect and develop a biosphere. We could get data in a situation where we control all the variables, without having to guess whether todays rain is the result of El Nino or La Nina or some other phenomenon. That data would help us learn what's really going on with our home planet.
How is trying to control the atmosphere of an entire planet with 6+ billion people on it several orders of magnitude easier than setting up a biosphere for 100 people on the moon? Fixing earth's problems doesn't have to be mutually exclusive with manned space exploration.
Correct me if I read the situation wrong, but aren't the lasers meant to be anti-rocket lasers as opposed to anti-personnel lasers? The only way a Palestinian could get toasted like an ant would be to strap themselves to one of those rockets, in which case their chances of survival aren't really affected much by the presence or absence of Israeli lasers.
It cost NASA Billions for Apollo. Not sure how much Surveyor cost.
While electronics have certainly dropped in price, propellants haven't. Reliability is a lot better than it used to be, but it's still an expensive business.
Any launch to orbit will cost 30-50 million?
I guess the Pegasus has been operating at a 10m+ loss per launch for the last two decades.
There are fixed costs for developing a launch vehicle, but what I'm trying to say is that by being frugal with your rover mass, you can launch on low end vehicles for something in the 10-15 million range instead of needing a massive 40 million dollar rocket. It's all about delta-V and mass fractions.
GEO Comm Satellites cost that much not because of their distance, but because they are massive. If you watch you mass and make a capable but very small rover, you will only need a fraction of the launch tonnage that a geosynchronous communications satellite would require, even accounting for a lunar transfer stage and a descent stage.
The Pegasus series of launch vehicles by Orbital Sciences is an air launched rocket that delivers small satellites to orbit.
You don't really gain anything from the altitude per-se. Orbiting the earth is far more about velocity than about altitude. What you do gain is a noticeable drop in air density, which makes the rocket dynamics much more agreeable. For large craft it's not worth it, but for small ones it is a viable method to get into orbit.
There's something to be said about a writer/producer being good at picking talent. It's true that bad actors could have ruined the series, but Joss probably deserves a bit of credit for casting well.
Just look at the difference between Star Wars episodes 4-6 and 1-3. Same writer, but one series was great and the other was trash, in large part (in my mind at least) due to the casting.
Getting into orbit isn't about altitude, it's about velocity. Run the numbers for a massive lifter. You might gain 5-6 miles worth of altitude, and less than Mach 1 velocity. That still leaves you needing a lot of acceleration to make orbit. It's nice for Spaceship 1, which is only suborbital. It's even the chosen approach for Pegasus, which puts some small stuff into orbit. Ultimately, for small craft it is marginally useful for avoiding a few troublesome parts of lifting off from the ground, but such an approach is useless for large launches.
DVDdecrypter has an ISO read/write mode. All my rips are 1:1 ISO images that I can then mount in Daemon tools whenever I feel like watching them. Then you can just play it using whatever program you would normally use on a DVD you put in the computer. DVDdecrypter can also burn the ISO's to blank discs if you're not planning on shrinking them. You can shrink using DVDshrink if you prefer single layer disks.
If I recall correctly, there is some free oxygen diffused among the water molecules. The gills on a fish don't perform electrolysis on the water, they just filter out some of the available oxygen.
Gates calling himself low tech is most likely an attempt to deflect further questions. It was well known in his time at Texas A&M that he would personally respond to many emails from students, and as he was leaving the university he made it known that he frequented a popular aggie message board. http://www.texags.com/main/forum.reply.asp?topic_i d=768382&forum_id=5

I for one, welcome our new free-flying fractionated overlords. Especially if they turn out looking like Summer Glau...
