Ironically, Bigelow and Adastra are two of the companies that they're talking about contracting with for this "new", advanced, ground breaking technology.
Not only does it include the delivery vehicle (Dragon); but, the delivery vehicle is a pressurized cargo container that is rated to be safe for humans to enter and certified to autodock with the ISS... or will be once they're done certifying it.
ESA's ATV (the first one was the Jules Verne) is the equivalent. ESA's cost was on the order of 200 million euro, in addition to the Ariane 5 launch vehicle that put it into orbit. Development cost was 1.35 billion euro.
That seems a harsh way to find out that your Windows machine has been rooted.
There are plenty of people who think that tracking down all the machines in these botnets and disabling them is a reasonable way of dealing with the problem.
As someone who lives across the river in Newport News (yes, that's the name of the city), I can tell you that we don't need no destruction to see little radioactivity symbols. We just need to count the ships. (Hint: Norfolk Naval Base and Newport News Shipbuilding).
Some of those authors have / had engineering and science degrees. That is part of what made them good at their job. Isaac Asimov and Arthur C. Clarke are classic examples.
That's because we effectively killed our nuclear industry decades ago. The Japanese and the French bought out the remains and now provide the bulk of the support for our infrastructure.
You could also argue it wouldn't see the multi megaton warhead stashed in the shipping container in the bottom of the pile on the cargo ship... The airborne laser is not the right tool for the job, being designed for a different purpose. That's what the scanners at the border crossings are for -- they're the right tool for that job.
I think it's fair to say that a multi-megawatt laser flying on a military aircraft which can target, hit and destroy an in-flight ballistic missile is not "girly". That is, unless the flight crew are all little girls dressed in pink princess dresses.
I doesn't. If this technology finds it's way into processors, it won't happen for years (several turns). By then silicon technology will have continued to advance upward and will be hitting feature size limitations (we're at like 25 to 80 Si atoms across, depending on the process, now). Then there will be a gradual ramp up of the technology as the manufacturers learn to use it. Let's also not forget that IC interconnects and all the support chips outside the processor will introduce limitations.
I keep seeing this kind of comment... Just because Ares is going to be killed, this does not mean manned spaceflight is doomed. The cancellation of Constellation is a recognition of the current budgetary limitations. There are other options on the table, like Shuttle Derived which uses existing tooling to accomplish the same job (albeit it requires 2x-3x the launches). There is money in the new budget to be used to fund development of commercial options like Atlas, Delta, Falcon, and Taurus II. And finally, the new administration seems to be favoring the recommendation of the Augustine Commission -- which was flexible path to Mars. Before deciding the world is about to end, let's wait and see what the Administration announces, what path they're going to take.
First, you shouldn't have (intentionally) crushed your daughter's dreams like that. Second, if you'd bothered to have done some reading, you'd find Obama's administration appears to be choosing the Flexible Path to Mars plan, recommended by the Augustine Commission. They're just killing Constellation because the money required to complete the program does not exist.
I can't see the youtube... But basically, you've got it backwards. Ballistic trajectories for long range are fired non-vertical. Vertical launch is for close range. Longest range is around 35-38 degrees from vertical (accounting for air resistance).
The German V-2 was capable of reaching space in a vertical launch with a light payload. Whether any ever did or not is not clear. The many thousands that were launched were generally not vertically launched.
it's all speculation until someone reads the budget and the new policy is announced. Now that that's out of the way...
Heavy Lift: There's an understanding that we need heavy lift. It looks like a 200mT launcher is out of the question for now; but, we have plenty of experience, thanks to the ISS, in assembline large structures in space. So, the question becomes what form does an HLV take: A Shuttle Derived (Jupiter) derivative or an amped up Atlas / Delta derivative? Either could ultimately reach the 100-150mT range. The Shuttle Derived gets there faster using existing tooling.
Composite launch vehicle: Let's assume, for argument sake, that ULA is one of the suppliers of the "taxi" service. Lockheed, who is one of the two ULA parent companies, and who supplies the Atlas 5 launch vehicle, is building the Orion CEV for NASA. If ULA does supply the launch vehicle, what crew vehicle do you suppose they'll use? Perhaps the one they already have the tooling for? The one that's already a NASA approved design? I think so.
Inflatable structures: That technology was sold by NASA to Bigelow Aerospace, who then developed it further and did some limited testing in space LEO. NASA was going to incorporate Bigelow's work into their habitats. If NASA drops it, for now, Bigelow appears to have plans to continue the work. They've booked a Falcon 9 flight for 2014.
Lunar descent engine: What made that engine interesting was the use of LNG/LOX as a fuel. It worked. Well. That's likely to find further use down the line; but, I can't speculate where.

It looks like they're going for Cheap + Safe. As fast as possible.

Umm... It's an Air Force facility located adjacent to the NASA facility.

So, yes, SpaceX Falcon9 + Dragon is cheap.
Maybe he's a scientist working as an engineer... like me. except I do sensors, not rockets.

Just pull CAT 5e. It's not that much work.
I know I'm being redundant; but, it's in the hopes you'll get the message.p>

It would burn a tiny hole in you; but, that wouldn't matter because the radiation flux would kill you within seconds.

China invented solid fueled rockets. If they're having problems... They will work it out within a few years.

light takes 8 minutes to get to Earth. CME's typically take a few days.

But he didn't follow one of the cardinal rules of the internet: Video, or it didn't happen!
