Well, big chunks of the US aerospace industry (i.e., their audience) still use English units. You don't see this in formal publications as much as you used to, but it's still fairly common.
Well, it's an analogy. Generally, in the spacecraft case, the plug is just pulled, for a bunch of different reasons (which is why it doesn't happen all that often). In this case, L'Garde was trying to reuse a bunch of technology they developed for previous inflatable structures in space. This led to the sail inflation mechanism weighing more than the Sunjammer itself, which is not desirable, and likely not what you would do if you started from scratch. No new contractor would want to come in and try and make the L'Garde proprietary technology work, and NASA is well aware of that. So, there will be sails flown relatively soon, but they won't look like L'Garde's Sunjammer.
Oh, yes. FAME (to pick my previous example) absolutely deserved to be canceled. It hurt some people I have real respect for, but there it is. I am sure the current situation is pretty similar. (This is analogous to firing a contractor when they are halfway finished building an addition to your house - it is so messy and represents such a real loss of money, and also such a loss of face, that it is almost never done without some real provocation.)
It's worse than that. There are slugs, pounds and poundals, and (IMHO) anyone who doesn't immediately convert these units to MKS is just being silly.
Sunjammer was to have a total surface area of ~ 1,200 square metres, so its thrust at 1 AU would have been 2 x 1361 W / m^2 x 1200 / c ~ 0.01 Newtons (assuming the sail had a near perfect reflectivity). On the surface of the Earth, that thrust would be generated by a weight of 0.01 / 9.8 ~ 1 gm, or ~ 0.002 pounds.
while that was an absolutely stupid thing to do, its not really relevant to the topic at hand here now is it??
It's not even really true; it's just bamboozlement for people who want to be bamboozled. If you listen to the actual fracking interview, he says that his goals, on this particular trip to the Middle East include outreach to the Muslim world, including reminding them in their role in the development of science. That is a non-surprising goal for an official trip to a particular region. I have a news flash - at the recent IAC meeting, he congratulated the Indians on the initial success of their MOM Mars mission. I suppose the Telegraph will take offense of that too.
I have met Mr. Bolden several times, and had the opportunity to see him in action. He is an excellent NASA administrator who is seriously focused on "boots on Mars," not self-esteem initiatives.
A vote of no confidence. I remember when NASA canceled the USNO FAME satellite - they said it was over the budget, but really it was over the management team. I expect that there is something similar here - fortunately, there is still NASA Marshall's Solar Scout, which is much smaller and cheaper than the Sunjammer.
Oh, and most of these are not legally treaties, although they (unconstitutionally) try and have the effect of treaties (again, they do this precisely because they know they could never get an actual treaty with the desired terms through the Senate) . The one good side of doing it that way is that a future President could abrogate the existing agreements at the stroke of a pen.
Agreed, but just because you have one boil doesn't mean you should agree to get more.
You mean the guy who shut your Parliament down rather than face a vote of no confidence? I don't see how you can regard him as legitimate or, for that matter, why you still tolerate having a Governor General.
Leave nothing to chance.
This is not a free trade agreement, this is corporations attempting to legislate without actually having to deal with pesky legislatures.
Anyone who supports the US Constitution should be against this.
Or they could have been some of Catherine the Great's Volga Germans, whom I believe still qualify for German citizenship, even if they were born in Russia and never spoke German.
There was lots of groundbreaking research published in German in 1930. By 1950, not so much.
It sure wasn't because of a groundswell of public opinion demanding it.
I would strongly favor bringing back the $ 1000 bill. It's not that you might use it every day (I don't use $ 100 bills every day), but there are occasions where it would be very useful.
There are now lists of millions of stolen passwords, and frankly none of them are safe. Why shouldn't someone set up a password security app (like captcha, but in reverse) so that a large web site could
- download a large stolen password list (even 1 billion would only be a few GBytes)
- checks (a salted hash) of your password against the list (say, salts changed every day or hour or...) and
- if yours is on the list, tells you to do better
It seems this would be much safer than just having some app that counts punctuation characters and tells you your password is strong if it has more than 3.
Make it profitable, and they will go. How do you think North America got populated* ?
*Well, there is making it a prison planet, and sending everyone who gets a felony. I am sure some would love doing that, as long as they didn't have to go.
