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.
Clearly you have never been to the UCLA campus because, if you had, you would have known this isn't true in the least. You can walk all over that place.
The problem in LA is the culture. People believe they are to be seen in their automobiles and they buy or lease expensive cars and drive them ridiculously short distances for that sole reason (if there is another reason, please do share but nothing really makes sense).
I worked for a company based out of LA for 2.5 years and we were there often. One guy lived a 10 minute walk from the office but chose to drive each and every day. He didn't buy an M3 to have it sit in his garage, after all. Nope, it sat in the company's garage instead.
I work in marketing analytics and, specifically, in measuring the effectiveness of online marketing campaigns at a customer level. Straight up click tracking is dead and this will do nothing which is purports as organizations begin moving away from siloed measurement of IMP -> CLK within single channels at an aggregate level and instead go down to the very granular cross-channel customer-level attribution.
If you really want to avoid detection and behavior tracking, I highly suggest you entirely disable cookies entirely (yes, I realize this is not worth it at all), otherwise you will not have accomplished what you had hoped.
That's like blaming the phone network for telemarketers.
Jesse, I told you to stop posting on Slashdot!!
H/R Drone: Do you have 5 years experience in the field?
Kid: I am 5!
Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:
- Disinformation and ignorance are diseases.
- Memes and computer viruses are diseases.
- Wilipedia contains information that leads to depression.
- Instructions on Wikipedia lead to substance abuse.
- This is getting entertaining, fill in your own reason here.
The secret bit Intel doesn't want you to know about!
One of the definitions I found was:
One who makes great sacrifices or suffers much in order to further a belief, cause, or principle.
I am sure that fits. While SpaceShip II is mainly intended for a non-exploration purpose, the program has resulted in some significant advances in rocketry and White Knight II has significant non-tourism use. These pilots have been involved in other space efforts, I remember the one who was injured from the Rotary Rocket test flights. There are lots of safer ways for these folks to make as much money as a test pilot is paid. They do what they do to advance our progress in aeronautics and space.
Martyrs? Who killed them for their beliefs?
Go away, troll. They certainly died while pursuing something intensely important that they were willing to risk their lives for. The fact that you weren't around to pull the trigger makes them no less martyrs.
I recently was given a business class trip on Cathay which was great except last legon a narrow jet the seats were arranged diagonally. That was horrible. Even when you can tilt all the way down. Look you want to be aligned with the axjs of flight.
Battle Programmer Shirase (BPS)
might be more realistic.
It might draw more talent?
