If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.
How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.
Weight vs. reusable life will become a design decision in rocket design.
This is cool but why is he driving on the wrong side of the road? They should fix that first.
I'm religious, fundamentalist, and I agree with you.
I simply multiplied my monitor by -i.
Now when I pretend to be working on it, the imaginary work becomes real.
Oh, man, this guy and I were cut from the same OCD cloth. I know it just looking at his pictures of Atari 2600 game boxes all sorted first by box style and then alphabetized. I used to do that when I was a kid and when I finally get the thing out of storage I'll bet a bunch of the games are alphabetized.
I have seven kids all homeschooled and we love to fire up Mame, and I've kept my Atari 2600 although they haven't gotten to play it yet and I need to bring it out of storage. And I love to have them go through interesting pieces of twentieth century history in chronological order - right now we're watching through old Disney and Warner Brothers cartoons together on Saturday mornings, in order. Next year they are going to watch all six Star Wars films in the order they were released, before we see Episode VII.
BTW, it's kind of adding insult to injury that the Pac-Man screen on that article doesn't match the actual console that is shown. I wonder what the kid thought of various ports of Pac-Man.
I think letting the buildings collapse on top of their residents is a much preferable alternative, instead of this mandated socialism.
In fact when this happened during the 1985 earthquake in Mexico people were elated that no retrofitting had taken place and citizens en masse celebrated the >30,000 dead people.
I mean who does this Eric Garcetti guy thinks he is?
I wrote about Republicans choosing ideology over facts. Your comment about drones has nothing to do with my argument.
Windows 7 was the product release of the beta version otherwise known as Windows Vista.
Microsoft is famous for reusing less code that most other software shops. On top of that the present Windows systems are a derivative of Windows NT not Windows 95, so I think it would be a safe bet to say that presently Windows contains comparatively little code from Win95.
The Israelis who have no qualms supporting state sponsored assassinations in the name of national security told the Bush administration that torture doesn't work.
For Xsakes, this are your friends telling you not to do it, because it doesn't work. What did Bush do? he carried on regardless.
This has become a signature pattern for the right in the last 15 years. It wasn't always that way. In the 80s and 90s one could disagree yet respect the opinion of Republican leaders and administrations, even if one didn't always agree with them. Somewhere around the time of the Contract with American ideology became more important than facts and it has been all downhill for America. The 2 trillion dollar invasion of Iraq on false pretenses, the loss of critical support across the world with unwarranted acts of torture, the obstructionist practices of the Republican congress v. the Obama administration.
Give it another 10 years and the present GOP will achieve from within what Osama Bin Laden foolishly tried to do with a few planes. He should have financed the Tea Party instead, and by now he would be further ahead in his goal.
Well if you don't like it you can exercise your democratic right and vote against it... unless you live in one of the many states that do not allow felons to vote.
Nice ain't it?
I understand Samsung's Ultra Power Saver mode also gives you several days on 20% battery power.
