The "gravity constant" that you are describing is the gravity acceleration at the earth surface due to the earth (where you may or may not have subtracted the centripetal acceleration due to the earth rotation) which changes with the position on earth mainly due to the fact that the distance from the surface to the center of the earth is changing (due to flattened at the poles and bulges at the equator). So this is more a change with location than a change with time. The ESA studies is more about the measurement of the earth gravitation from "outside" the earth, to create a model for orbit evolution with time. (Jn parameters, with n>= 2) And they study this evolution in time, for all location. So it's not exactly the same.

(Anyway, the g that you talk about can be seen as an evaluation of the Jx modelisation at earth surface so this is of course related. Bu the study is more about time change than space change)

The share of women having babies in the women population is very close to the share of men having babies in the men population.

Insurance on your cars will not reduce your electricity bill. But reviking internet services, TV cable and cell phones will definitively reduce that cost, so yes, go for it.

The goal is get more information about comets. The only way to reduce the luck in the mission is to get more information about comets. You could probably make two mission, the first one studying a comet, the second one having a landing device. But you will not be sure that the second comet that you visit is similar to the first one. And it will cost a lot more. So adding a secondary landing probe to Rosetta, even if it may fail, is a cheaper solution, yet relying on some luck.

The comment doesn't speak about stopping immigration, it specifically refers to stopping Ebola by closing down (or quarantining) everyone coming from anywhere Africa. Including US citizen.

You want to shut down all travels from Africa when only 4 countries have a significant number of Ebola case? You have no idea of the size of Africa, do you?

Not if what the US bosses ask them something which is forbidden by Irish law.

That's not what I understand from the article (my understanding of the article don't exclude your interpretation, but I see it differently) You are right, the control software of the Fregat did exactly what it was told to do (assuming the article is correct) but the input was wrong. But was the input directly done by an human or is it the result of another software (more likely) which had an error? If this is the case, then it's a software error. (this could also be an human input error before this software)

From what I understand (but this article is reporting that some press agency report that someone unamed told them something... the result must be very accurate) it's more likely that a software A gives a bad result to the Fregat control software B. I'm not able to determine from the article is the software A is bad or if there was a bad input to software A which result in this. I understand from the article that software A is also embedded, but see my remark in the parenthesis before about how accurate this article must be.

So to not see NATO missile launchers closer to the western border, he pushes this border to the west? What a stupid move.

How do you conclude that this is an idiotic mistake from the currently available informations?

It depends of the exact orbit. But even if it's possible, you don't have any more fuel to reach graveyard orbit later. Better conclude that you can't use them and collect money from arianespace insurers.

Then If you want space done right go retired American vehicles

If watching this video is a crime, why not arrest this men which must have seen it to be able to make this comment?

Of course I see such outrages. Here: http://apple.slashdot.org/comm...
Every time that an article speaks about diversity, there is always a fucking moron to complain that we don't see such an outrage. Disproving it's own point.
