To extend your argument, nuclear power isn't bad, it's not accounting for the side effects. If you made nuclear companies pay for the cleanup and storage of their waste, it wouldn't be profitable to have a nuclear power plant.
Of course, if you did that with nukes, you'd have to do it with coal, oil, and natural gas. Which would raise prices. Which is bad for the economy.
So what do you value more, clean air and water, or a healthy economy?
So, why should I not be worried? Please enlighten me.
Because the electricity you used to post this message was probably generated at a coal-burning power plant, which spews radioactive material into the air all day, every day. Current totals are around 27,000 tons of uranium and thorium per year for all coal plants in the world.
So, really, you should be using less electricity if you want to get radioactive elements out of the atmosphere, not blaming NASA for putting niggling little amounts of radioactive material into spacecraft. Heck, if it succeeds, all that bad stuff is gone forever!
People were all up in arms about Cassini's launch because it had the largest RTG ever launched. They were afraid that it would break up on launch and spread plutonium all over the planet.
Unfortunately, they ignored the fact that coal burning power plants put more radioactive material into the air every minute than was in the Cassini probe, and that the plutonium wouldn't atomize. It would sink like a rock into the muck at the bottom of the ocean, just like the dozen or so nuclear subs that have been lost. And it would pose no threat to life on Earth.
Nuclear and radiation are buzzwords that freak out people that don't understand. I'm radioactive right now. Should I be buried in a Nevada salt mine or shot into the sun?

As a there is a whole lot more of space need for the plant life a seed creates then it's initial size. And that takes up a lot of space... so the 'space ship' would have to allot for this space.
An inflatable greenhouse would be able to provide enough space for plants while remaining small during transport. Also, the pressure differential would keep it inflated without any supports. Soil, water and air would all be provided for once we got there.
I also don't think you're seeing the big picture. There is more to eating that satisfying caloric and nutritional requirements. Plants provide chemicals that cannot be reproduced in a laboratory or do not survive well outside of a biological system. There's also the idea of keeping a crew happy over a period of 2 years. Happy people work better. Food choice and variety is an important part of this. This is why they don't do pills and patches on the space shuttle.
Finally, we'll need to figure out how to live on Mars eventually, and that means growing food locally. It won't be a totally closed environment like Biosphere 2, because processing plants will provide the raw materials like air and water, and Martian soil is just as fertile as Earth soil.
You say you want the most doable solution, and then say you want to research pills and patches for food requirements. People have been gardening for ten thousand years. It is a fully developed technology, unlike a-meal-in-a-pill or the DARPA patch you're talking about.
Weight isn't an issue, our launch systems can handle the weight. Price isn't an issue, since plants reproduce and we can use those seeds for future crops, unlike pills. The only issue is that most people have never grown their own food, and think it's some magical process that only experts can do. They have trouble wrapping their minds around the fact that we have lived for millions of years without supermarkets, and the only way we'll get off this mudball is to relearn the agricultural knowledge our ancestors knew.
Mmmm... yes. Because I would love to not eat when I'm millions of miles from home. And of course I wouldn't want things that actually *taste like stuff.* And to do that for 2 years is exactly my idea of a good time.
We can grow things in greenhouses on mars in martian soil. And we won't have to bring as many CO2 scrubbers. And we'll have an earth-like situation for the astronauts so they won't get too homesick staring at a red Arizona for a year and a half.
Plant's are plenty compact to ship. What's more compact than a seed? A few seed packets are about the same size as a pill bottle, with the same amount of weight. And they taste better and can make oxygen.
Life expands and grows. Did our ancient ancestors 'infect' the land when they crawled onto it? Hell no, they exploited a rich ecosystem and thrived by taking a risk.
We *should* take a complex ecosystem to Mars. All this mess about how we should preserve it is ludicrous. It's a freeze-dried rock. Let's get some surveys done regarding the possibility of life and possible origins and then 'infect' the whole planet.
Burt has lots of CAD drawings and sketches for his concept of an entire private space program including orbital vehicles, space stations and vehicles to get out of LEO.
Actually, looking at the list of stuff PSU supplies, it's factually incorrect.
PSU offers webmail, online course registration, online classes, free web space w/ http access and limited CGI, network access in dorm rooms, and I think there are areas with wireless scattered around the campus.
But that doesn't mean the sorority girls aren't slutty, or make up for the fact it's a football school first and a teaching school second.
There are lots of long words and numbers in that article. And it's really long. It makes my brain hurt. Linux must be complicated if it takes that long to explain its security benefits. And if they have to hide them in a long article like that
And besides, last night while I was watching $stupid_cable_news_show I saw an ad for Microsoft. It said they were secure. Then I saw that same ad in $idiot_management_magazine. They can't advertise it if it's not true, so we should go with Windows Server 2003 for our new application.
And, besides, I just got Microsoft to sell Windows Server 2003 for $50 per copy by saying we'd switch to Linux. Here's the box, now go install it.
They already swipe the passport through a reader at customs. I had it done on my way back from my honeymoon. The computer screen then showed the information from the database to make sure my passport was valid.
Desigining cities isn't an option for a lot of places. Like Harrisburg, where I live. Not only does it have horrible urban sprawl that limits the desirability of city design, but the entire area is divided into townships. This balkanizes the area so the only governments that can effect real change are the state and federal. Local governments are caught up in internal and external rivalries.
So the state or federal government needs to provide a system that can be overlayed over a city or town's current infrastructure and mandate its construction.
Of course, if you did that with nukes, you'd have to do it with coal, oil, and natural gas. Which would raise prices. Which is bad for the economy.
So what do you value more, clean air and water, or a healthy economy?

Yeah, because we'll have to know what sites to avoid when we're actually trying to get work done.
Or maybe less than 1% of pro-open-source folks have the money to spare to donate to Mozilla. $30 is my gas budget for the month.
Gravitation? What do you mean? Lack of on the surface? Or lack of gravity in space. Either way, we've solved this problem.
Uninhabitable surface? In what sense? No, I won't go strolling on Mars in my jockeys, but it's not that bad once you have a spacesuit on.
You're spelling it wrong. It's pronounced nukular.
Of course, Nissan wouldn't want that, now would they...
But sorry, honey, I'm already married.
Oh, and it's got two fans. One in the PSU, the other blowing over the heat sink.
And besides, it's cheaper just to pump the atmosphere through a nuclear engine to get thrust.

So why bring pills again?
Plants grow well in mars soil, even better than earth soil. It's the atmosphere's lack of 02 that's the problem, not the soil.
Just Google it and you'll find lots of sources.
I'm also not sure how well plants will grow when they're frozen or blasted with UV Rays.

Anyone with the skill to implement half the stuff Rensselaer has would avoid that place like the plague.
Unless they want slutty sorority girls to drunkenly fawn over them.
In which case they're too busy to implement a WAN.
How can the truth be biased? All of those statements are truthful, with only the last one showing any opinion whatsoever.

Linux gaming is already 'there' for me. All I seem to play is Civ!
