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.
You have a point, that name could be taken the wrong way. You could use a code-name that describes it's benefits while avoiding that problemmatic pronunciation. How about: ""Another Plug-in Proc Succor"?
The headline could be confusing. The garage was significant. My point is that people extend the concept in their heads and imagine a lot more than it really was. That is the myth part.
society functions on trust. you can't have civil society with people who are anonymous. you need to see their emotions and their intent. even wearing sunglasses is evasive and makes you seem untrustworthy
we already have it in the form of everyone with a cell phone camera. if anything remotely interesting in public happens, 5 or 6 people are filming it and its uploaded within the hour and mirrored forever beyond any possible take back within a few hours
if loss of privacy bothers you, the concept of little brother should bother you more than the concept of big brother. you can hold government accountable and force it to abide by rules and sue it. you can't do that with every random anonymous yahoo around you
1. the footage shouldn't be public. there's a lot of interaction that cops deal with which is embarrassing and private for individuals. your underage arrest has to live with you forever? your suicide attempt or domestic issues should be open to prying eyes? no, no, no
2. the footage shouldn't be under the control of local police departments. "oops, sorry, i 'bumped the server' and we lost the footage of that controversial shooting by my buddy nate. oh well"
state level? federal level?
and then really solid rules about who gets to access what footage must be enacted. something similar to HIPAA rules and fines
The problem is the illiterate deer! We put up perfectly good 'deer crossing' signs and the deer wantonly ignore the signs and cross wherever they feel like it!
> if your software product confuses someone with almost 20 years of experience in computing, you're doing it wrong
Speaking of which... Software developer with over 20 years of experience here... I tried to figure out iTunes WTF?! How can they make something so confusing? I just wanted to take 10 mp3s and put them on my daughters iphone. "If you continue I will erase everything on the iphone"...?!?! nope nope nope nope...
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.
Is everybody ok with this?! Trial Lawyers *PAY* a politician to make bad laws that will generate more lawsuits, so he does. Google *PAYS* other politicians to make laws favorable to them. So they do.
It's completely outrageous and a generation ago would have been a huge scandal. Now it's business as usual. There is no more democracy.
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.
Anyway, I have better uses of my time than to waste another minute with you.
