Space Shuttle and Space Station Photographed Together

The sun had just set and it was getting dark. I noticed two bright dots in the sky in close proximity to each-other. At first I thought "airliners", but had to rethink my hasty conclusion because the lights weren't blinking. I had to stop walking to really take in the scene: two very bright white dots in the eastern sky, about one closed fist at arm's length away from each other, moving across the sky slowly but consistently.
Having observed ISS before I knew how bright it could be. This certainly seemed like another ISS sighting, but what was the other thing? Then I remembered: the shuttle had launched not too long ago for a mission to ISS. Could I have just witness the moments after undocking? I checked NASA's data as soon as I got home and sure enough the undocking time was just prior to my observation.
This was among the last shuttle missions so I'll never forget that moment!
Couldn't find one, so decided to make it. I basically rotated and cropped it to get as much of ISS as possible, then added a bit more Earth. This way it looks like the planet is naturally just falling below the horizon of your monitors, rather than being cut off. Fortunately the space background is a nice deep black, so that's easy to extend.
If anyone else is running (2560x1440) x 3, feel free to use it: http://www.helpertubes.com/images/iss_shuttle_7680x1440.jpg
Or if you prefer, this version crops the top solar panels of ISS, so you get a closer view, and less artificially generated Earth: http://www.helpertubes.com/images/iss_shuttle_7680x1440_clos...
Enjoy!

Edit: Actually, one Soyuz (TMA-21 on Poisk) and a Progress (M-10M on Pirs). The ATV is the Johannes Kepler.
The 2x Soyuz (counting the one taking the pic) fit 3 each, the Space Shuttle fits 5-7, Progress and ATV are unmaned. Anyone knows how many in the ISS?

Something I find more impressive is the B52 Bomber, first flew in 1952, finished production in 1962, expected to be in service until 2040. Will be in service for almost 100 years.
If like an aircraft, you were doing 1 hour of maintenance for every 10 - 20 hours driving, I'm sure your car would be more reliable.
I originally enlisted in the Navy as an Aviation Structural Mechanic (AM), and my first command was an F-14 squadron where I was assigned to airframes. On average, we scheduled 40 man hours for each flight hour (sometimes as high as 60). The F/A-18's that eventually replaced the Tomcats took about half that, but for most aircraft you're looking at 10 MMH/FH, at least, for mx alone.
That said, not all aircraft are created equal, and not all those Tomcats required all 40 scheduled man hours. Maintenance manning, at least in the Navy, is largely determined by man hours. So it isn't uncommon for commands to log as many hours as they can to keep billets, and possibly get a few additional ones. Billets are taken away if you show you can operate at fewer man hours.

The Boeing B-52 Stratofortress was introduced in 1952. Its mission is presently projected through 2044.[1] That's a ninety-two year mission.
There were 744 built, unit costs range from $9.28 million (1962) to $53.4 million (1988). The most recent new production was 1963, over a half century ago. Effectively the planes are rebuilt periodically, though some original components may remain (I'm not fully up on my B-52 maintenance procedures and schedules).
"Flyaway cost": $9.29m, in 1955 dollars, $82.53 in 2014 dollars)
Present maintenance costs: $10,406/hr.
That is equivalent to the purchase price of the aircraft every 8,000 flight hours.
AAA publishes a "cost of ownership" report for automobiles which assumes 15,000 miles of travel and an average of $0.05/mi maintenance, or $750/year.[2] This suggests that a B-52 level of maintenance is at least twice the going cost of automobile maintenance. But not hugely out of line given relative capital costs.
GlobalSecurity.org claims B-52 total service life being 32,500 - 37,500 flying hours.[3] Over the 92 year life of the program, that corresponds to a duty cycle of roughly 4.6%, vs. 5.7% for the automobile referenced above. It also gives us an annual maintenance cost per B-52 of $4.2 million -- or 5% of the total purchase cost. Over the 92 year life of the aircraft, that's equivalent to purchasing 4.7 new planes.
(Taken from a longer response to an allegation about failure to incorporate demand-side depreciation in GDP, largely deconstructed, demolished, and dismissed here.)
Also, incidentally, I dropped you an email concerning your "Internet with a Human Face" blog posting, seen that by chance?

Similar arguments apply to military aircraft: the last B-52 was completed in the mid 1960s. Dies and machining for the SR-71 Blackbird were destroyed after the initial production run was completed. Aotomobile production and economics simply don't apply.
> In 1968, a presidential order required that all molds and tools used to build the SR-71 be destroyed so that the plane could never be built by anyone again. This also meant that spare parts could not be made, so if there were any major problems, planes in storage would have to be cannibalized. http://www.strategic-air-command.com/aircraft/reconnaissance...
> 8. How many SR-71's were built? 50 Blackbird airframes of various designations. The dies or molds were destroyed as directed by then Secretary of Defense McNamara to prevent any other nation from building the aircraft. http://www.wvi.com/~sr71webmaster/srqt~1.htm
Richard Feynman expressed great scepticism about the Shuttle, and its scientific value. In his books he writes how he never came across a single scientific paper that referenced it -- check out the chapter titled "Committing Suicide" of "What do you care what other people think?".
Note: Not saying the Shuttle was the most suitable solution, but I think that 'it was never referenced in papers' is not a useful fact.
It would be like publishing a particle physics paper using data gathered at the LHC and not mentioning that you got the data from the LHC.
This is astronaut Sunita Williams providing an extensive video tour of the ISS. Gives you a feel for what life is like up there. For example: they need to take care that the use of the stationary exercise bike doesn't set up vibrations that shake the exterior solar panel arrays.
[D]uring the Space Shuttle Endeavour's last trip
to the International Space Station in 2011 May,
a supply ship departed the station with astronauts
that captured a series of rare views. The supply
ship was the Russian Soyuz TMA-20 which landed in
Kazakhstan later that day.
