There are multiple mock-ups of the ISS, for various purposes:
The Space Vehicle Mockup Facility at Johnston space center contains replicas of many modules of the ISS, some of them assembled together.
The Neutral Buoyancy Laboratory is used for EVA training, and has a modules in the pool
The Space Station Training Facility does not have full modules, but ...
To be as practical as possible, the Space Shuttle mission STS-75 experimented with a space tether. For the record, the tether did break. To be fairly exact, it did break for reasons that wouldn't have broken it if the line had been shorter. So in a certain sense (but only a limited sense), we have already seen a space tether break ...
First things first: Lyndon Johnson had very little, if anything, to do with the site selection for what was then called the Manned Space Center. The selection of the current location of what is now known as the Johnson Space Center was made in September 1961, over two years before President Kennedy was assassinated. It was a very common ploy in those days ...
What is it (today)? Nothing.
What was it?
Edit: Changed my mind and decided that as you mention in the question, this was a Unified S-Band station. This was an Apollo-unique communications system. What we knew in Shuttle as the MILA tracking station is located in this spot on the map.
The Wikipedia article on MILA states that it had
Two 30-foot (9.1 ...
Once SpaceX has a continuous pipeline of rockets being launched, refurbished, and reused, the latency -- the time it takes for a single stage to go from launch to launch-ready -- won't matter.
If the turnaround time is, say, 70 days, and SpaceX has 10 first stages in their stable, they can maintain a launch cadence of 1 per week. 4 ASDS would probably be ...
For shuttle, they didn't. At least not all of the consoles. Note the wood-covered consoles in the rear, they face the window.
This is Firing Room 4 which controlled the last 20 or so shuttle launches.
A view from one of the consoles in Firing Room 3 which also faced the windows.
4 firing rooms, one for each of the high bays in the VAB.
The original plan called for four rectangular firing rooms, 28 by 46
meters; one was never to be equipped.
i.e. to support the original Apollo flight rate projections.
The firing rooms were used for prelaunch checkout of the vehicles so they could have had several in ...
In simplest terms: The upper limit is the point at which the object asserts enough gravity to collapse itself, and the available limit on materaials available.
An object of sufficient mass should self-collapse into a spheroid; for silicates this is estimated to be several hundred miles diameter; note that Ceres is above the self-rounding limit, and is about ...
The last few missions doing GTO boosts have had the ASDS in reasonably close to the same location in the ocean. The lower energy CRS-8 mission was further in shore, since it had the performance to come back that much closer to shore.
There is a fair bit of variability possible, but it does appear that there is little benefit in going much further east, ...
It doesn't appear so. Their home page features a story on imaging the fires from space (https://www.jpl.nasa.gov/news/news.php?feature=7278)
Looking at the image featured in that story, JPL is near the right side of the picture (northeast of Glendale).
Employees could be severely impacted, of course.
Supplementary answer: the political role that Albert Thomas played in the site selection was not mentioned in the accepted answer.
That includes the reason the Johnson Space Center, originally known as
the Manned Spacecraft Center—was put in Houston in the first place.
The year that Kennedy proposed traveling to the moon, 1961, it
happened that U.S. ...
For now, no. The landing zone is in the middle of the ocean. Setting up a factory there is prohibitively expensive.
IIRC, the long-term plan is to launch from somewhere further West so they can land at Cape Canaveral. That would require flying over land, which requires FAA permission which isn't easy to obtain, This probably requires lots more flights ...
Although not orbital, which was the explicit question asked, a rocket has been launched from the UK to beyond the atmosphere in October 2015.
It is reported by the BBC today.
The BBC article also writes about the sites for planned spaceports, including an article about a proposed vertical rocket launch site in Sutherland.
A lot of these proposals are ...
There seems to be persistent interest, see NSTP2, which is an invitation from the UK Space Agency for "proposals for industrial research projects that will contribute to the introduction of sub-orbital flight and satellite launch operations in the UK".
Proposals have to address:
determine how sub-orbital or small satellite launch vehicles ...
