Boeing To Take Space Tourists On Its CST-100 Spacecraft To the ISS

confused one Re:Public access (47 comments)

You haven't paid for anything yet... The 4 billion is for development and infrastructure. You're paying for the pad modification/construction, manufacturing of first articles, flight certification and testing. Normally, if this were a commercial airliner, Boeing would pay for this themselves. They would recoup the cost over the couple hundred planes they constructed and sold. Since there is no business case with and end result allowing them to recoup the cost, they're having the primary customer (NASA) pay the Non Recoverable Engineering costs (NRE). This is standard practice in industry (any and all industry).

Once certified, NASA, as a customer, will be buying seats on the CST-100, as a service. They're not buying the rocket for their exclusive use; think of it as buying seats on a commercial airliner. NASA will be the primary customer initially; but, not the only customer. Same thing happened with the commercial airliner industry -- in the very early days, one of the major customers was the government and a buyer of cargo space was the U.S. Mail service.

ISS is not going to be the only destination in the future. Bigelow Aerospace plans to launch a habitation module or two in the next few years. They already have a contract with Boeing to use CST-100 as a transport. It's just the beginning...

Boeing To Take Space Tourists On Its CST-100 Spacecraft To the ISS

confused one Re:Public access (47 comments)

Although NASA is helping fund the development of the vehicle, to meet their safety specifications, NASA is buying seats on a CST-100, as a service, not buying CST-100s. Think of it as NASA buying seats on a commercial airliner. The vehicle has 7 seats. The way I read the story, NASA is requiring 1 seat for a NASA pilot on the test flight and 4+ seats per launch to ISS. That leaves empty seats...

SparkFun Works to Build the Edison Ecosystem (Video)

confused one Re:Edison missing a lot (75 comments)

Intel is selling an awful lot of Atoms, for a processor who's market supposedly disappeared. FYI, they're embedded in all kinds of equipment.

SparkFun Works to Build the Edison Ecosystem (Video)

confused one Re:Power Consumption (75 comments)

Because of the architecture, you have to implement a timer using the processor's built in precision timer/counter. There's one there... You can get sub-microsecond control resolution if you implement it right. The risk is that if you're running a multitasking operating system your timer might get interrupted. Of course, another way to go is to have a secondary I/O processor handle the task and act as the interface -- this is very common when dealing with Intel processor platforms.

Original 11' Star Trek Enterprise Model Being Restored Again

confused one Re:Restoration (99 comments)

Then you risk having two copies...

Scan you, destroy the original, transmit scan data, reassemble you at the other end. That's the only way to be sure... and would explain all the "transporter accidents"

The Future According To Stanislaw Lem

confused one They'd get bored (195 comments)

Yes, maybe they're all genetically modified self absorbed drug addicts... Eventually they'd get bored and come on over to see if we had better drugs here than they had; something they hadn't tried before. Or maybe they'd just get the munchies and come here looking for better snack food. Or get tired of us bringing down their high with all our fighting; and come by to tell us to "mellow out, man."

CERN Tests First Artificial Retina Capable of Looking For High Energy Particles

confused one Re:In the retina? (60 comments)

Yes, yes it is. The retina does the edge detection and detects changes in intensity. What the brain gets is not full streaming video.... It's more like lossy, high compression data. The brain fills in all the missing data as needed.

WD Announces 8TB, 10TB Helium Hard Drives

confused one Re:Helium? (296 comments)

Of course I know where it comes from... It's extracted from natural gas as a byproduct and initially helium comes from alpha decay of radioactives, as you say. Producing it through radioactive decay, that's the slow way. Helium is produces in a number of fusion reactions. They don't have to be energetically favorable to produce helium. Now... if you want cost effective, then that's another problem.

confused one Re:How about sharing legitimate advice? (151 comments)

EMP does not equal CME

No... but a big CME, as it interacts with the Earth's magnetosphere, can generate an EMP. That's what actually causes the overload in electrical systems, not the charged particles.

Should Cyborgs Have the Same Privacy Rights As Humans?

Should Cyborgs Have the Same Privacy Rights As Humans?

confused one Re:What kind of cyborg? (206 comments)

Not at all. There are plenty of examples in history. U.S. was formed, among other things, over an argument about unequal representation and the rights of citizens. Slavery in the U.S. was justified by categorizing a group of people as not being equal. Japanese internment camps were created during WWII as part of a knee jerk reaction to the bombing of Pearl Harbor. What I'm saying is that once modified humans become common, all it might take is a seemingly simple series of events for the populous to push for a distinction to be made, which might, end up limiting or removing the rights of the group through legislation.

Should Cyborgs Have the Same Privacy Rights As Humans?

confused one Re:What kind of cyborg? (206 comments)

Cyborgs are just kinds of humans

It's conceivable that something could cause a knee jerk reaction and suddenly a bill appears suggesting people with brain enhancing modifications are no longer "people". Then all your inalienable rights go out the window. Perhaps a law is passed saying modified humans are no longer human and therefor no longer citizens. Again, your rights go away. It's something that should (eventually) be addressed before stupidity happens.

While a person is smart and can make rational decisions, sometimes people become dumb, panicky, dangerous animals.

The Argument For a Hypersonic Missile Testing Ban

confused one definition is important (322 comments)

I'm wondering how they'll define hypersonic missile. All space launch vehicles are, in some versions of the definition, a hypersonic missile. All re-entry vehicles are, again, hypersonic missiles (some are hypersonic ballistic missiles).

Battle of the Heavy Lift Rockets

confused one Re:No Competition Here! (211 comments)

I've come to the conclusion that this may be the unspoken official plan. Congress is driving NASA to do what they're doing; but, the Administration is sort of sitting back quietly saying very little. Note how you don't hear much from the Obama administration about SLS; but, they keep pushing Commercial Crew. I think it is possible they're just waiting for SpaceX (or one of the other commercial contractors) to fill the void and provide commercial launch capability. NASA has leased launch facilities to SpaceX and Boeing already, including pads 39A and 40 at Canaveral. Heavy lift is the next logical step. Musk has made a lot of noise publicly and given the presentation to Congress and the Administration. They're taking him seriously enough that members of Congress are trying to derail his efforts to protect their constituency. I believe the Administration is giving them the same serious consideration, standing back and waiting to see if they can pull it off.
