NASA's HI-SEAS Project Results Suggests a Women-Only Mars Crew 399 399

globaljustin writes "Alan Drysdale, a systems analyst in advanced life support and a contractor with NASA concluded, "Small women haven't been demonstrated to be appreciably dumber than big women or big men, so there's no reason to choose larger people for a flight crew when it's brain power you want," says Drysdale. "The logical thing to do is to fly small women." Kate Greene, who wrote the linked article, took part in the first HI-SEAS experiment in Martian-style living, and has some compelling reasons for an all-women crew, energy efficiency chief among them: Week in and week out, the three female crew members expended less than half the calories of the three male crew members. Less than half! We were all exercising roughly the same amount—at least 45 minutes a day for five consecutive days a week—but our metabolic furnaces were calibrated in radically different ways. During one week, the most metabolically active male burned an average of 3,450 calories per day, while the least metabolically active female expended 1,475 calories per day. It was rare for a woman on crew to burn 2,000 calories in a day and common for male crew members to exceed 3,000. ... The calorie requirements of an astronaut matter significantly when planning a mission. The more food a person needs to maintain her weight on a long space journey, the more food should launch with her. The more food launched, the heavier the payload. The heavier the payload, the more fuel required to blast it into orbit and beyond. The more fuel required, the heavier the rocket becomes, which it in turn requires more fuel to launch.

Where's this IT manual you're referring to? I should have just been looking there to solve all of my problems instead of, you know, being a competent network engineer.Sure would have made things easier and reduced the amount of 36 hour days I had.

IT in the military isn't as rigid as you think,at least in the areas I worked in. Sure, operator manuals and the training to go along with it are going to be step-by-step, but that goes out the window on day 3 when nothing works even though "nothing changed" on the network.

I think you're way off base. Systems are delivered, lab-tested and ready to go, by the lowest bidder. Then they fail on day 2 because they were never developed for the actual environment we've got. Now it's up to me to make it work and not go to bed until it does.

There's little "doctrine" when it comes to IT in the military.Flashy, good ideas get pushed down onto us all the time, just like I'd imagine it is in any sector. There'll be plenty of innovation by a good IT team because they're going to stay abreast on recent technology and bring in anything they can demonstrate to improve the network or the user experience.

I think you shot your point to hell at the end by showing that it really depends on the individual. When you're on the clock 24/7 and you don't leave until it's fixed, you learn to be all kinds of gymnast flexible. Or you shouldn't be in the job. The problem in military is that it's hard to get rid those under performing, whereas in the civilian world I hope they just fire you.

As a soon-to-be retired job seeker, all I want is what's in your last statement. Being military doesn't make me more or less suited for the job. Evaluate me based on my experience, achievements and skills I can bring to the job in question.Just give me a fair chance in the interview so sink or sell myself.

Although this is a crap dice propaganda article and many of the comments scare me, they are enlightening, also. You guys are helping me prepare for interviews.

Why does it have to be different? Win8 was different, and MS got torn to hell for it. This is exactly what everyone wanted, isn't it? You get a start menu that doesn't take over the entire screen, applications in windows, a definitive switch to tablet vs. desktop mode. Win8 was supposed to be this unifying experience, but it weighed far to heavily on the touch/table experience rather than unifying. This looks like a great solution, in my opinion, but then I don't really have a problem with Win8... well, Win8.1, specifically.

I think if commercial use were allowed, the number of drones buzzing around would skyrocket. Every event, from sports to news, would have a dozen different drones flying around looking for that perfect shot. That presents the safety concerns. Some of these quadcopters aren't exactly small and could hurt a few folks if dropped into a crowd.

Although I'm sure it's really just a money issue at the heart of it. There should just be a mechanism to register drones for flights just like they do with helicopters, blimps, etc. I think some of the footage you could get from them would be really cool to see on the news.

If someone steals your card, deactivate your card.

Sure, but in the meantime, the PIN prevents the card from being used since the thief doesn't know what it is. It also prevents the card from being cloned (assuming that's possible) and used elsewhere even though you have your card in your wallet. It's the whole "something you have" and "something you know" security model.

You can do this in a number of ways. IBM chose to do all of them. Why do you find that funny? -- D. Taylor, Computer Science 350
