Re: This seems like a good argument for ion drives
Ion drives unfortunately are pretty useless for the quick thrust you need for orientation and positioning purposes. Ion drives are fantastic for slow but steady acceleration - movement between planets (or Protoplanets in this case) is a perfect case and that's what was used on Dawn. But for orientation it's too little thrust to achieve in any sort of useful time frame the desired results.
To offer an example, your currently doing science pointing instruments at ceres. But you need to change orientation to point the antennas at earth to deliver that science data. With hydrazine thrusters that's work of maybe 15 minutes. Say the transmission takes another 15,and another 15 to get back into science orientation. You've lost at most 45 mins of science time. With ion thrusters you would need at least 2 hour to change orientation in one direction (probably more) and so for the same action you've lost 4 hours 15 mins science days. If you have to do this every day that's 3,5 hours of science time per day lost. The mission will need to be massively longer to account for all of that missing science data. And that means you need more fuel for the ion thrusters, etc, etc. And in the end it just works out way more difficult to do it with ion thrusters. Not to mention the orbital calculations to work out how long you need to apply the ion thrusters for to get into the correct orientation position when you're talking reaction time frames measured in hours. If you under or overshoot with hydrazine, it's a quick fix, just squirt some more with ion you've got another couple of hours to wait.
Hope that explains a bit why we still use chemical thrusters for orientation instead of ion thrusters. :)
Re: I can't get the sensor to fit
It's all well and good to say that but if you do any job a hundred times it stops being a special job, it just becomes step 7b of job 256. And you've got 4 more jobs to do before the end of the day or the boss is going to get pissy with you. And this bloody bracket, which you've complained about half a dozen times but no one listens, is not going in easily. So you just take your hammer and get it to fit easy as pie. And move on to step 7c.
This is how cock ups like this happen. Because people are more worried about the pressure they'll get from managers for missing a deadline. Their manager is a more immediate problem then some future potential problem for some astronauts they'll never meet.
To avoid this, you really need a culture in the workplace where problems and delays are dealt with properly and no blame is put on the worker when they occur. It sounds very much like Roscosmos does not currently have that culture...

Re: A different name for every site?
"The Carter parents were a quiet and respectable Lancre family who got into a bit of a mix-up when it came to naming their children. First, they had four daughters, who were christened Hope, Chastity, Prudence, and Charity, because naming girls after virtues is an ancient and unremarkable tradition. Then their first son was born and out of some misplaced idea about how this naming business was done he was called Anger Carter, followed later by Jealousy Carter, Bestiality Carter and Covetousness Carter. Life being what it is, Hope turned out to be a depressive, Chastity was enjoying life as a lady of negotiable affection in Ankh-Morpork, Prudence had thirteen children, and Charity expected to get a dollar’s change out of seventy-five pence–whereas the boys had grown into amiable, well-tempered men, and Bestiality Carter was, for example, very kind to animals. "

I was visiting Pheonix for work about 10 years back, and my colleagues and i were told by the hotel not to walk in the neighbourhood after dark or in the early morning.

Needless to say, we stuck to the bar for the evenings!
Re: Give Russia's reputation for poor workmanship
Oh Spartacus... Dont let me tell you some of the stories i know from the aerospace world - you might never fly again! Lets put it this way, mistakes happen. When they happen, the technician writes up a concession, an engineer designs a fix, and the technician applies the fix and everyone moves forward.
If there's an aircraft out there without at least a 1000 concessions on it (for all sorts of things, holes drilled in the wrong spot is just the easiest one), then I'll eat my hat... The Space biz, is no different...
But dont worry, your still safe to fly... probably... ;)

Officials of what?
Are we talking Democratic Party Officials from Michigan that did this test? That would seem to be countered by the last comment that it wasnt someone from the DNC (or at least not authorised by them).

Re: Even their "good" practice is bad.(@ Jake)
People, people relax please. This is America. Expect the forthcoming flurry of lawsuits from Santa Clarans suing Verizon for the fact that throttling the emergency services data allowance prevented the fire departments from doing their job, and that therefore Verizon were directly responsible for the loss of the Santa Clarans homes and properties.
After Verizon loses and has to pay out millions, they will change their policies to never again throttle an emergency service.

I'm beginning to wonder what you would have to do now as a CEO of a big corporation to not get your bonus?
Here's a few ideas:
- Wipe out a species of African Rhino?
- Drive your Ferrari into a busload of school children whilst getting a handjob from a prostitute?
- Murder a popular member of the Royal Family (Charles doesnt count)?
- Be pictured hugging Donald Trump?
Ahhh, who am I kidding, none of those would have even the slightest effect on CEO Bonuses... Well maybe the Trump one...

Sorry Steve but you're just plain wrong.
Manufacturers build to a spec, and assemble to assembly instructions. If your drawing/3D model has an error in it, the manufacturers are not going to know that. They will manufacture exactly what is on the drawing. Now if this was down to a manufacturer cocking up (which does happen) then you'd be right, but then a failure like that SHOULD be picked up by QA and would then be repaired or replaced. But this is quite clearly a design error - the design just cannot tolerate general dirt, dust and grit getting into the keyboard, nothing manufacturing does could generate that level of poor design.
Apple design their parts and send the designs to various manufacturers for production who then send their parts to Foxconn for assembly. Neither the manufacturers or Foxconn are responsible for this cock-up - this turd of a failure falls squarely in Apples lap...
(from a designer - but thankfully not an Apple one!)
Depends on the CEO of course. But do you really need to ask when it comes to Ginni "We need to cut costs but i fly in a helicopter" Rommety?
Your both right. Heat is transferred away from the sun in the forms of direct energy and high energy particles.
The impact from the particles causes localised heating (think of it as little explosions or perhaps better, think of it as a missile hitting a target - the missile might be small and the target big, but it does transfer a lot of energy!). This heating is dependent on the local strength of the solar wind.
The direct energy from the Sun is gentler but constant. Light radiation interacting with the particles causes heating exactly like what ahppens every day on Earth.
Which of these two is dominant depends on how far from the sun you are (as direct energy tapers off via the inverse square law), and how strong the local solar wind is.

Re: Can we see the original evidence first?
"That would be commercial suicide."
And refusing to co-operate with the government is likely to see you either in prison (various embezzelment, corruption or conspiracy charges) or worse.
I'm not just talking Russia here, any regime where the government has complete control of the courts and the media - China, Vietnam, etc. - all make it incredibly dangerous to say No when the government comes knocking. I'm sure in places like the UK, US, etc it is also difficult to say No to the men in black suits. But there's a difference between something being difficult and something being dangerous...

Yeah that all came about due to amisunderstanding. A politician was on a train and overhead some people complaining saying "The suckers waste so much energy! They go on and on all day. They've got way too much power. If we could reduce their power, it would be better for the whole country. But of course the suckers will never get regulated. They just suck!"
He walked into the office the very next day and got high power vacuum cleaners banned and considered it a job well done.

Aluminium smelters will still be there and working (barring some unforeseen major global problem in the Aluminium market) in 10 years time and well beyond.
Cryptocurrency miners? Well Bitcoin is all but past the point of being profitable to mine, whilst also now being blocked from being traded or used as a currency in a lot of major market places. So in 10 years, it will probably only be a hardcore still using/trading it. And they wont be mining it anymore. Other cryptocurrencies? Well since people finally are beginning to wake up to the scams, I expect that the bubble wont be too long in bursting. 10 years time? I have my doubts if it will still be such a power draw.
Now if you're the power company supplying electricity in this area, and you have a choice of supplying an industry that maybe uses a little less electricity, but is guaranteed to be there long term, or an industry that might use a lot of energy now but is definitely only a short term prospect. You would definitely always go for the long term option. And this IS an either/or situation - investing in more energy generation capacity is very expensive and takes years to come online. You're not going to make that investment based on the crypto mining bubble. Well not unless your either crazy, or have drunk the crypto currency kool aid...

2 points here
"It called for NASA’s Administrator to “pursue capabilities, in cooperation with other departments, agencies, and commercial partners, to detect, track, catalog, and characterize near-Earth objects to reduce the risk of harm to humans from an unexpected impact on our planet.”
1) What is the additional budget for NASA to perform all of these new tasks? If no budget is forthcoming now, then dont expect NASA to be able to do anything when the big one is incoming later....
2) in cooperation with commerical partners. Right.... Because there are profits to be made spotting asteroids? Funnily enough, I havent heard of any firms doing this previously. How are you going to make it so profitable that firms start building facilities?
A good sentiment, and something that needs to be thought about and prepared for, but I'm reading a lot of hot air and wishful thinking here. I'll believe its being taken care of properly when I see significant funds being given to NASA for this task alone (and not merely being stolen from other NASA missions).
Re: Listening to AT&T and Uber?
Hey whats wrong with the National Association of Marlon Brando Look Alikes?
A small test
Here is a small test to answer the question - does this group really represent XXXXXXX start-up firms (XXXXXXX -> insert industrial sector as appropriate (tech, agriculture, energy,etc)).
1) Is the budget for talking to people about the start up groups interests more than the cost of a night at the pub?
If the answer is Yes, then the group does not represent start up firms. If No, the group MAY represent start up firms.
Start up firms by the very definition do not have cash to splash around on lobbying. Nor do they have time to work on policy documentation. They're too busy trying to get their products off the ground. Lobbying is the domain of the established players who have budgets to waste.
The best you can hope for from a real start-up is a night at the pub in the name of "networking".
Re: I don't understand why we need App Stores

Re: Training the trainer
In the first year of my bachelor degree (Aerospace engineering in the early 2000's), we had a mandatory computing course.
In the very first lecture, the professor started explaining what was a mouse, a keyboard, etc., etc. After about 10 minutes of this, he began to show us how to open a Word document. At this point, he proudly announced that by clicking on the X in the corner you could close the document (all spoken in a tone of voice that left no doubt to anyone that this was amazing magical bleeding edge computing technology). He clicked the X, a pop up appeared "Would you like to save the changes you made to this document befoe closing". 3 options were available - Yes, No and Cancel.
The professor clicked Cancel. The document did not Close. He clicked the X again. Up came the Pop-up. He clicked Cancel. The document did not Close. He clicked the X again. Up came the Pop-up. He clicked Cancel. And so on for a full 5 minutes. At which point I got up and left.
I didnt bother going back to that class. I just turned up for the exams and still got a high distinction. To this day, I have no idea how long the professor kept clicking close before someone eventually took pity on him, or perhaps he did it until the end of the lesson. I have no idea.
Re: Sun optical mice, circa 1985
"Isn't there a handwriting capture/mouse pen that uses paper printed with a very fine grid for a similar reason?"
Yep. It's called Livescribe. Or at least the one I've got is. From the little usage I've put it to, it works perfectly. Unfortunately it didnt exist when I was at uni (where I might have actually put it to good use), and I dont really have a day to day use for it anymore. But it works great.
Here's hoping the case is thrown out with extreme prejudice (or whatever the equivalent local legal term is). Having the court basically go "No, your case is ridiculous and there are no further grounds for appeal. Go away and stop bothering us." would be highly deserved (not to mention hilarious).
All a question of motivation...
It's a question of motivation. Scammers know they need to move quick (well they should have needed to move quick but based on TSB's response they probabaly could have taken their time) to make a profit and so are incentivised to pump out the scams fast.
TSB know very few customers are going to go through the hassle of changing banks just because of this debacle. And when you know that, then you know there's no need to pay for that expensive overtime to repair the system or invest in things like disaster recovery, roll out testing, rolling back systems, etc. TSB's motivation is to spend as little as possible on things to do with the customers and save as much as possible to go to their bonuses.
One motivation inspires quick action and the other does not...
