+ - WSJ Reports Boeing to beat SpaceX for manned taxi to ISS->

PvtVoid (1252388) writes "The Wall Street Journal reports (paywalled) that NASA is poised to award a key contract for manned transport to the International Space Station to Boeing over rival SpaceX:

Recent signals from the Obama administration, according to the officials, indicate that the National Aeronautics and Space Administration's leadership has concluded on a preliminary basis that Boeing's proposed capsule offers the least risky option, as well as the one most likely to be ready to transport U.S. crews to the international space station within three years. The officials cautioned that a last-minute shift by NASA chief Charles Bolden, who must vet the decision, could change the result of the closely watched competition.

From TFA:

As the area covered in sea ice expands scientists have said the ice on the continent of Antarctica which is not over the ocean continues to deplete. CEO of the Antarctic Climate and Ecosystems CRC, Tony Worby, said the warming atmosphere is leading to greater sea ice coverage by changing wind patterns.

This isn't dissenting data.

Yep... And — for a car analogy — if I'm driving, I want to be able to drive on any road with any speed by car can go, and park wherever I see fit. No matter, who built the road or attends to the parking lot.

How about a phone analogy? When I pick up the phone, I want to be able to call anybody else who has a phone.

Aren't uranium (as opposed to plutonium) bombs pretty bulky?

Not really. The critical mass for U235 is 50 kg or so, while for PU240 it's about 40 kg. Moreover, a U235 bomb is way easier to make, because it doesn't have a predetonation problem like plutonium. Just take two hunks of U235 and drive one into the other with an explosive charge. Bang. City gone. This was the way Little Boy worked. It was so simple they didn't even bother to test it before dropping it on Hiroshima. You can't do that with PU240: the neutrons get so thick as it nears criticality that it blows the charge apart in a sub-critical burst. This is why you have to use very sophisticated shaped charges to assure a perfectly spherical implosion.

PU240 is easier to produce. U235 is easier to build a bomb with. It has proved very fortunate for the world that these two things are true.

Erm, you are mixing up stuff.

The anti nuclear horde always pointed out that the current plants are not safe. (And on top of that they don't want new ones).

And now you try to use that as a stick against them?

The plants weren't unsafe when they were built. They are unsafe now because they are far beyond their design lifetime. We have better plant designs now. Why is this so hard to understand?

Computers can figure out all kinds of problems, except the things in the world that just don't add up.

Working...
