Air Force Sends Mystery Mini-Shuttle Back To Space
dsinc sends this quote from an AP report about the U.S. Air Force's X-37B spaceplane:
"The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. It's the second flight for this original X-37B spaceplane. It circled the planet for seven months in 2010. A second X-37B spacecraft spent more than a year in orbit. These high-tech mystery machines — 29 feet long — are about one-quarter the size of NASA's old space shuttles and can land automatically on a runway. The two previous touchdowns occurred in Southern California; this one might end on NASA's three-mile-long runway once reserved for the space agency's shuttles. The military isn't saying much, if anything, about this new secret mission. In fact, launch commentary ended 17 minutes into the flight. But one scientific observer, Harvard University's Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, speculates the spaceplane is carrying sensors designed for spying and likely is serving as a testbed for future satellites."
Must be over-due for a good conspiracy theory
"...speculates the spaceplane is carrying sensors designed for spying and likely is serving as a testbed for future satellites." That is what we need. More speculation. I speculate it is full of bacon and will be headed for the moon. Everyone needs bacon, even those going to the moon.
Military version of the shuttle, etc etc... conspiracy, etc etc ...

Up at the same time 4179 Toutatis makes it's closest flyby? Not a coincidence. While all telescopes will be trained on the 3-mile rock gently drifting past, the true mission of the X-37B will be underway. What's that mission? Oh you know, the usual...space-aliens from Vega.
I'm sorry, but your opinion seems to be wrong.
Why not use the word cowering or is that just too transparently anti-military for the axe-grinding author?

Highly unlikely that it's spying on other countries, right? There's got to be something else at work here.
Also, it's not a conspiracy theory if there's actually conspiring a happening.
A bit of reading also tells us they can fit a module with 6 persons riding it.
So it can be anything riding aboard.
Who from?
Not like it's working anyway..
This little baby is either repairing, upgrading or deploying new satellites that interface with the human body. The system uses modified ultra wide-band radar to induce nerve endings into firing. The same system uses the radar to extract return information that betrays neural activity. This is fed into a strong AI-based super computer for decoding and storage. Why a strong AI? Think of turning a human into a puppet and you won't be far off...
Also, it's not a conspiracy theory if there's actually conspiring a happening.
So does that mean it goes from a Theory to a Law?
Don't know something? Look it up. Still don't know? Then ask.
Most likely they wanted a spy satellite that they can replace the optics on every year. Now that they can't send the shuttle up, they need a new way to repair and upgrade spy satellites.
I thought the Sirians didn't like bacon.
the preceding comment is my own and in no way reflects the opinion of the Joint Chiefs of Staff
The X-37B is not one-quarter the size of the Space Shuttle, it's one-quarter the length of the Space Shuttle. The launch weight of the X-37B is 5.5 tons. The launch weight of the Space Shuttle is 125 tons. This ignorance about the meaning of dimensions reminds me of the Stonehenge scene from Spinal Tap.
This thing has be photographed from top to bottom. The internet is for familiar with it than my proctologist is with me. But every story, there have been many lately, talks about top secret and mystery.
There is no secret about this craft. Its future payload may be secret satellites, but it is not a secret. FFS!
Theories do not work that way! Good night!

Duh, ya think?
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
I'm sure it only has 5-6 nukes on board, max.
It's good to see the USAF with some general-purpose space capability. They now have something that can go up to low orbit for a reasonable cost, stay up for a while, and carry a range of payloads. Useful.
You know some in the military are hoping to use it, if they don't already have a prototype ready to go on the spacecraft, to deliver a "Project Thor" type kinetic weapon system to orbit. While the bay of this thing (7'x 4') wouldn't be able to fit the larger or even medium class Thor weapon, it would be able to fit a smaller one for taking out a motorcade/vehicle/person.

The mini shuttles are obviously escape pods.
I only wonder where the Attack Vessel is to which they belong!
Cost free eBook I read (by iBook/Kobo/Amazon/ObookO/Gutenberg etc.): "The Green Odyssey" by Philip Jose Farmer.
The shuttle rode on the side of the stack for a reason - so it could use it's three main engines for the entire climb to orbit. These engines were designed to be the best rocket engines ever developed (which meant they'd be very complex and expensive) and, therefore, to be re-usable. They were on the back of the orbiter not as an error, but precisely because that meant they would come home for re-use instead of being thrown-away on each flight. What you seem to think was a mistake, was in fact a design feature and part of the argument for making the scheme both technically and financially workable. As long as going to space requires throwing away most of the vehicle, it will remain the exclusive domain of governments and rich businesses/businessmen. Nobody but the super rich could afford to fly from NY to LA if the entire airliner was discarded during the flight and the passenger parachuted onto the LA runway in a small escape pod.
In actual practice, nothing about the shuttle system turned out to be as cheap as initially intended; that rarely happens on the first-generation of any world-leading technology. Had we built a 2nd generation of shuttles they likely would have performed far better with lower turn-around times and costs.
First, the shuttle was not a camel designed by committee, nor was it a bloated whale. In actual use, it ended-up being far cheaper to operate than the old Saturns it replaced (NASA has finally run and published the numbers now that the program is over) it just never came close to the goals that were set for it.
NASA spent years studying many different shuttle system designs and took designs and bids from Grumman, Lockheed, Boeing, Rockwell, McDonnell Douglas, etc and compared many of these designs not just on paper but with an amazing amount of engineering analysis. In the end, they were forced by a bi-partisan political consensus (including President Nixon and the Democrats who ran congress) to choose the system with the lowest up-front development costs but the highest operational costs (they all wanted small numbers while they were in office and did not care what the numbers would be later when they'd be out of office).
It's a common urban myth that the USAF drove the need for a delta wing; it's not true. The USAF needed that for polar launches from VAFB with aborts back to California instead of mid-ocean (need 1K miles of cross-range in that scenario because the Earth keeps turning after you launch... ) but NASA came to the conclusion that they too needed about the same capability. The USAF gets blamed for this feature only because they were smart enough to see their need first. It is true that the USAF needed the big payload bay with specific dimensions for a certain payload but here, again, the requirement was not particularly different from what NASA wanted anyway.
Finally, the USAF did not happily turn its back on the shuttle; At the time the Challenger exploded, there was a shuttle on the pad at VAFB in California (not for launch, but for facility checkout ahead of the first California launch) and they were gearing-up for many military flights to come. The USAF was ordered to transition to other vehicles in the aftermath of the Challenger accident and investigation. Part of the investigation was a re-assessment of the risks of shuttles and that lead to a decision to abandon the use of systems like the Centaur upper stage for shuttle, which were thought to add far too much risk to an already risky vehicle. If the US had had a mush larger fleet (perhaps 10 orbiters) and the ability to remotely operate them on the riskiest missions, the USAF would likely have continued to use shuttles. As it was, there were military missions and payloads even after Challenger during the transition to EELVs.
This would be more accurate: A standard Atlas payload shroud protects the Atlas from the aerodynamics of having an asymmetrical winged vehicle on its nose during the climb to space.
The Atlas was never designed to have a set of wings and tail fins up on its nose generating unbalance lift and drag vectors during ascent (think: arrow with tail feathers relocated to the nose). That's NOT to say that the Atlas could not handle the situation, but rather that the money has not been spent to study the matter sufficiently and to alter the flight software for the guidance system of the Atlas.
It's also important to note that the X-37 was never designed to be exposed during ascent; the wings and tails might not be up to the loads and parts of the top might not be up to the thermal environment (things get pretty hot on the way up from air friction as you accelerate past mach 2 before you get out of the atmosphere) and the vehicle has a different orientation to the airflow from what it has during reentry). As a NASA project, the X-37 was intended to ride to orbit within the payload bay of the shuttle, where it would be deployed for its test mission and then return home on its own. It was only a test vehicle and was not intended to make many operational flights that way.
The author could have easily chose to say "protected" rather than "hidden". The word "hidden" carries implications ... but in this case the implications are a joke; Even without a payload shroud, the contents of the vehicle would have been blocked from view because they are in a payload bay just like on the shuttles
The USAF has dreamed of a small space plane like this for decades. They tried to build one in the early sixties (X-20 DynaSoar, with a crew of one) and were actually quite close to flying before MacNamera (yeah, Mr. Vietnam, himself) killed it to spend the money some place else. You are free to guess where he needed more money. Neil Armstrong actually flew the launch abort tests for the X-20 in a modified aircraft at Edwards long before he transferred to NASA and the Gemini and Apollo programs. It must have seemed like a miracle to some in the USAF when NASA and a stupidly short-sighted congress abandoned the X-37 program. The Air Force essentially got the program for free from the NASA junk pile (though they have, of course, spent a bunch on it since).
A little unmanned plane like this is a sports car; you don't use it for day-to-day trips, but you use it on special occasions and for special things. A zippy little platform like that can be used to test lots of cool new tech like new sensors. New sensors could generate massive amounts of raw data and be tested looking at most of the earth in all seasons and looking through all weather. You could fill the payload bay with solid state drives or even regular hard drives and save everything in a completely raw, lossless, uncompressed format along with extra data for analysis while downloading only small subsets of the data live. When the vehicle returns, you get back all the raw data, any performance/diagnostic data you chose not to downlink, and the sensors as well (for further analysis, and possible upgrade and re-flight)
It's the ultimate spy satellite development platform
You are referring to asymmetric keys with "2048 or 4096" and mix it up with symmetric keys, which are typically 128 to 256 bits. But even then, if you can brute force 64bits and now you can brute force 74bits, that is still 54bits of security margin, which is very, very safe.
It is safe to assume governments can currently brute-force something like 65 bits, so 128 is still plenty. Those who think they need 256 are mostly the clueless idiots.
..space is affecting your sensors/systems. That makes sense for low-flying spysats, which are actually worn down from atmosphere and eventually are slowed down until they reenter atmosphere.
I remember a "Hughes Danbury Optical systems" company having an open R&D position for some kind of satellite camera system that needed (simply speaking) "its lenses cleaned from stuff". Apparently the residual atmosphere in 120 km height does indeed do some damage to cameras. That can be apparently rectified with some sort of cleaning system.
If you can recover your satellite, you can look at that damage and optimize the system/the cleaning system. I guess that is exactly what the USAF is interested in.
The "too secret to be transmitted" argument is imho opinion from the tinfoil spectrum of arguments. They could easily stuff their ultra-secret spysat with one-time pads and use that for ciphering instead of storing the spied data onto storage. That will save them the reentry mechanism.
These days laser and microwave links can easily downlink Gbits/s. And certainly there are crypto devices which can process at that data rate without requiring too much matter, energy and space.
It must be either 007 "snatch enemy sat" or NRO "develop sensor and inspect after one year use".
What exactly did Mr Super-Musk achieve ? He down-cheaped the work of a SS Sturmbannführer and NASA director Wernher von Braun. Super-Musk essentially rides on the hard-won and extremely expensive R&D work of the Third Reich and the USA. Did he invent anything novel ? No.
...well it could be a specialized replacement for the Shuttle, but more likely its a replacement for the high-altitude spy planes - e.g. SR-71 and similar. It's can be more effectively moved around than a satellite so it can easily be where they want it and when. True, people can track it and try to hide from it, but they may not have time to - at least for things like the Cuban Missle Crisis (though to be honest, those days are likely long long gone any how).
