IIRC the screen of that phone is actually made of Gorilla Glass, which is pretty impressively tough stuff. Obviously not tough enough for British journalists mixed with a sharp metal corner...
Exactly. And the MSL is going to be nuke powered, none of this fussing around with solar panels. Of course the MSL is going to be HUGE compared to the MER landers.
The USSR bounced plenty of probes off and past Mars before and after the Mars 3 lander. Getting onto the surface of Mars is no trivial task. I think they had 7 failures (not including launchpad kerfuffles) where the probe either stopped responding, missed the planet or created a new crater.
Also, if you're putting a robot on a sand planet, wouldn't it kind of make sense to have some fans to blow off the sand from the solar panels?
Because it was designed for a 3 month mission. Every ounce of weight added is a massive deal to a project like that where it would either add cost or require weight to be removed from somewhere else. As it was they were really testing the limits of the parachute/rocket/bouncy ball re-entry method.
If they were really serious about a long duration rover project they would have sent an RTG powered probe... kind of like what the Mars Science Labratory will have.
Granted, but they switched to LED lights awhile back when doing any new construction, you can pick them out for miles away at night because of the brilliant green light as compared to the incandescents.
I was up in Fargo, ND visiting family for Christmas (yah shoor ya betcha) and a traffic light was out on a 6-lane intersection. Guess what? Everyone was calmly proceeding as if it was a 4-way stop. No drama, no retardation.
This whole thing is a non-problem. It's just that lazy journalists love it because it's "irony". It's not really ironic unless you're Alanis Morissette, but it makes for an easy, shitty space filler. Notice how in that story the SIGN is also covered in snow? ZOMG! We need heated road signs! Woe is me! Signs can sometimes become obscured by snow, the horror! The HORROR!
Well, for one you wouldn't need to heat them that often, if at all. These are the same cities that need to maintain fleets of snow removal equipment, having to occasionally brush off a lens isn't the end of the world.
Secondly, bulb life. What does it cost in labor to maintain incandescent bulbs versus LED bulbs? Not sure if it's significant or not.
And then how often do northern cities get hit with snow and winds strong enough to clog up traffic lights? As a North Dakota native I can say "Not very often". Honestly the only lights I've ever seen obscured by snow were from getting plastered FROM snowplows kicking up snow.
I remember playing the original Tribes multiplayer over a 56k modem, you'd get decent latency, around 100-150ms ping, and the modem connection could handle the bandwidth the network code used.
CAT I versus CAT III in the F-16. It's not so much the hardpoints as it is that with the extra inertia the munitions impart the pilot can ham-fist past the flight control computer and get the aircraft into a bad place aerodynamically. It's not a G-limit per se, it's an angle of attack and roll rate limit. If a pilot pulled too many Gs and then tried rolling it could get the jet into a deep stall.
Uh, forget to take your fucking medications today, dipshit? Fuck you and the horse you rode in on.
I never said hydrogen was the best solution to ANYTHING, only pointed out that cracking it from hydrocarbons isn't the only place it could be obtained.
Maglev flywheels? Hydrogen is an unmitigated boondoggle and you're talking about maglev flywheels? Did you manage to find a high temperature superconductor bearing, or do you want a cryogenics plant to go with your magic pink unicorn? To quote from an internet jackass, "show me the fucking product".
Hydrogen is an energy transmission device, it's never been a SOURCE of energy. We can't "mine" hydrogen or produce it out of nothing.
You could make the argument that hydrogen electrolysis would work for solar or wind farms to store generated energy, but I have no idea how efficient that would be. I'd imagine it would need to be on a very large scale to be worth it.
LOTS of people, and yes, it is disgusting. My parents are smokers and their computers get an incredible coating of brown oily crud all over the internal components. The smoke changes regular old dust into a sticky, clumpy mess that is a pain in the ass to clean.
If someone smokes so much around their computer that it leads to a buildup of enough of this goop to be a plausible cause of failure, well, tough crap. The warranty they sell contains language for not being responsible for "other external factors". Guess what nicotine addicts? Chain smoking can be one of those external factors. Same as if you had the computer in a fast food restaurant and the components get coated in fryer grease, it's not covered by the standard consumer warranty.
My breakthrough was using 8" salad plates for dinner instead of normal dinner plates. It sounds stupid, but it worked for me. I could sit down and eat a massive meal, my brain or stomach or whatever apparently doesn't have a "full" kill switch, I just eat till the plate's empty. Smaller plate = smaller portions.
If you weighed 380 pounds, I'm going to guess 6'2", 30 years old (wild guesses). Your basal metabolic rate (BMR) would have been 3170, that is you would burn 3170 calories in a day just laying in bed, before any physical activity.
If you only ate 2000 calories a day (be it 2000 calories of salads, ice cream, lard or refined white sugar), you'd definitely lose weight. Calories in - calories burned gives you a great idea of if you'll gain or lose weight, regardless of what "kind" of calories they were.
It sounds weird, but if you consume just 100 calories more than you burn in a day, in a year that's 10 pounds. That's assuming you keep increasing your consumption as your BMR rises when you gain weight, but it's close to that and I don't feel like calculus this early in the morning. But do that for a period of time and suddenly you're 100 pounds overweight.
I recently bought a new car, a 2008 Nissan, and I noticed that the RF gate opener to get into my parking lot at work doesn't function now either. It works like the Tolltag / EZ pass badges where the card is not powered and is detected by an RFID like transceiver, now I have to roll down my window and wave the pass around like a moron to get in.
These types of ion engines are only useful once you're in orbit, they're of no use in a deep gravity well or in an atmosphere. They are useful for things such as station keeping thrusters in satellites where you don't want to have to carry a lot of fuel with you.
Sure, they'd be nice for a Mars mission as well, the problem is that they require external power. Not a big deal when you're talking about a couple hundred watts of electric power for less than a Newton of thrust. When you're talking about hundreds of kilowatts it gets a lot more impractical.
You hit on exactly the problem people don't discuss with ion engines. They require a source of electric power. The Deep Space 1 probe used solar panels, but it only has 2.5 kW of electrical power available. Large engines would take hundreds of kilowatts, more than any solar array could provide and be of a practical size.
Maybe a nuclear fisson power supply? But that would add a huge amount of mass and volume to the spacecraft. Not to mention how up in arms some people get when you talk about launching nuclear material into space.

It could be a full frontal Bea Arthur sucking off Rush Limbaugh and it'd still be more energy than this quackery.
Unlikely... he got the conversion correct.

Easy Bake Ovens don't use lightbulbs anymore, they have a small electric heating element built in.
A water cooled 9mm Gatling gun? Good luck with that.

Power != energy. Energy is not measured in watts. Come back once you understand that.

I'll have to try that. It doesn't have a mounting bracket (it's intended to slip in the sun visor), but some double sided foam tape would fix that.
It's F-15 (with a hyphen). The F-15 is not a fly by wire aircraft, it uses hydraulically boosted mechanical controls.
