The most unrealistic thing in space operas is the notion that the human crew could do anything in terms of gunnery or navigation better than a computer.

While definitely not using realistic physics in any way, I liked a space battle in one of Iain M. Banks' Culture novels. A horribly beweaponed Culture ship is describing to its human passenger precisely how it is outwitting and annihilating its alien foes, mentioning that there's a particularly good moment coming up - eventually admitting that it's merely running through a slow-motion replay, the real battle having been over in a matter of milliseconds.

The Planetary Society also has decent in-depth coverage of (usually unmanned) spaceflight.

For space tourism flights to the International Space Station, they're regarded as spaceflight participants rather than 'proper' astronauts (or cosmonauts).

Having seen quite how much training fully qualified astronauts and cosmonauts have to go through, I wouldn't be surprised if they become some vaguely protected terms in the not-so-far future...

Offensive Unit All Through With This Niceness And Negotiation Stuff is just a friendly neighborhood warship.

I've seen half-serious suggestions that, should Scotland gain independence and create its own navy, all its ships should be named after Culture spacecraft...

The parachute that brought the latest rover to Mars also disintegrated during testing. However NASA proceeded with the design knowing that the atmosphere on Mars is not nearly as dense as it is on Earth.

They got it working in testing after that initial failure - and even that failure provided extremely useful high-speed video of its deployment.

Note the colossal wind tunnel. This latest, flying saucer tested parachute is way larger than that Curiosity parachute - so they've figured out a whole new testing regime. One that helpfully more closely matches conditions in the Martian atmosphere, too.

A microphone has already been landed on Mars - unfortunately there was a risk of data corruption if the camera hardware it was attached to was turned on, so the microphone itself never got switched on...

I travelled with a large external hard disk as well, once - which also got taken to one side and swabbed for stuff. Internal monologue: OH NO MY PRECIOUS DATA ... Oh, it's just the possibility of it being a bomb they're worried about.

On another occasion, I had fun with my home-made, Arduino-powered dSLR timelapse gadget - it got thoroughly inspected by the TSA. I'd already opted out of the backscatter X-ray whatsit, only for a swab-for-explosives test to give a (false-)positive. Eek. Cue being taken to one side, where they looked in my bag and found the timelapse-o-tron...

To give the screeners their due, they let me go after a few minutes - after I'd heard their complaints about the potential radiation doses they and the passengers were receiving from the backscatter X-ray thingers, and after I'd provided advice on what sort of camera to look into buying for a budding photographer.

Security fun elsewhere: carrying a plastic bag of loose change through the Eurostar security in Brussels (it basically looked like an amorphous, completely opaque lump on the X-ray) - and a random customs check at a UK airport giving a (false-)positive swab for some sort of illicit drugs. Eek.

+1, Interesting.

(Thanks!)

I guess "fully steerable" means "within ~20 of zenith" to you. But that's not what the rest of the world considers "fully steerable".

Oops. That was in reference to his Green Bank Telescope link - Arecibo being only partially steerable...

The Extremely Large Telescope is a compromise - what they really wanted was the 100m-diameter Overwhelmingly Large Telescope.

Their naming committees are either entirely humourless or gloriously taking the piss.

The worlds largest single dish telescope is still the Green Bank Telescope (http://en.wikipedia.org/wiki/Green_Bank_Telescope), which at 100m is ~6x the size.

World's largest fully-steerable single-dish telescope - the Arecibo Observatory is larger still at a diameter of 300m! (Impressive Arecibo exploration video here. The thing's sodding enormous.)

I went looking for the largest diameter multi-dish radio telescope. It looks like the biggest terrestrial 'telescope' is the Global VLBI system created by combining the European VLBI Network with the US Very Long Baseline Array - it's like some massive team of superheroes combining to save the Earth from some terrible secret of space. Or whatever. Apparently they can also add space-based telescopes when that just isn't enough. Which, quite frankly, is showing off...

My thoughts when seeing one of the beautiful, 10m diameter Keck optical telescopes up close a few years ago? I've had full control of a telescope bigger than that.

Radio Astronomers: Compensating For Something.

Piwik is a self-hosted web analytics package. In other words, your visit to an EFF page is being tracked by the EFF.

I dunno, I always get a big belly laugh whenever I log into something and see that horrible 1980s B&W X11 desktop, complete with ugly 'X' cursor.

Try flying on a Virgin America plane with the LCD screen inflight entertainment systems in the seat-backs. They'll often mass-reboot the things before or after a flight, briefly revealing that retro-fantastic, monochrome stippled background with 'X' cursor...

Do we have any Mars rovers close enough to the poles to not get sunlight in winter?

The non-roving Phoenix Mars probe landed sufficiently far north that reduced sunlight due to an approaching winter caused its (expected) failure. It most likely got buried by carbon dioxide ice later on anyway - orbital photos showed its solar panels got crushed...

For keeping space probes warm, radioisotope heater units are pretty common. Apparently the Chinese Moon rover has them - but it sounds like it hasn't successfully closed itself up in order to keep heat inside.

It's entering its second lunar night - it landed on the Moon on December 14th.
