It's a glorified Steadicam mount. Like the 'smart guns' carried by Vasquez and Drake in the movie Aliens. A spring loaded linkage connects the load to a body harness, but with added linkages that can transfer the weight of the harness to the ground.

The Martian atmosphere is already 95% CO2. Burning oil there to raise CO2 levels would be pointless. Besides, there are no Martian life, let alone plants, as far as we know.

Especially considering the general lack of oxygen there.

So I can give up the micro-kinis and go back to boxers? There will be much relief all around.

They're not going to tell you WHY they are bringing a secret spy shuttle home. Maybe it does need more propellant, but telling people that will give the Enemy clues to it's performance envelope. I'm actually surprised that they are even telling us when they are bringing it back.

Not just ebola, but one could argue that the United States is hobbled by an outdated constitution in responding to a wide variety of modern day issues. For example, airports and borders, traveller's rights, electronic surveillance, intellectual property rights, and a host of other issues.

You can tell me that your dog ran away,
then tell me that it took three days.
I've heard every joke,
I've heard every one you say.

You think there's not a lot goin' on
but look closer, baby, you're so wrong.
And that's why you can stay so long
when there's not a lot goin' on.

Pi? No wonder! Pi is wrong. They should be using Tau.

Let me put this in perspective for you. In the US, fifteen people have died by being struck by lighting, but only one person has died from Ebola.

You need to look at an outbreak map. Sure 4000 people have died, but 3999 of them were in West Africa, and one was a West African visiting family in the US. What you really need to worry about is lightning. You have a far better chance of dying by being struck by lightning. There are an estimated 24000 lightning deaths per year.

Easy! Rig the body scanners with temperature gauges. You register as hot, you get side-lined for a med check.

HAZMAT FAIL! Gotta do up those zippers all the way, or it doesn't work.

No, not necessarily. A vigilante is someone who watches for wrongdoing. When you're in line and you ask someone to guard your stuff while you throw your pop can in the recycling bin, you've appointed them to be a vigilante.

False dichotomy. They could snub both. Dump the Shell pieces and release a whaling set.
