Ftfy On a more serious note, whatever software issue they found must have been very serious to cancel a launch - and do we know if it was with the actual sats, or somewhere else? Has anyone heard a word on what it might have been?

Was there just one 2nd stage engine burn? Do they always get to low orbit/ISS with a single 2nd stage engine burn?

Helium leak?

Definitely. Related to this, look at an mx motorbike during a jump - riders adjust pitch of the bike mid-air with throttle and or brake. A bike can also be steered by, well, steering - turning the front wheel - while the front wheel is off the ground. Here are a few related demonstrations with a bicycle wheel, skip to 35:50 and 23:00

Phoboths and Deimoths, obviously.

Come again?

Huh, that's what I thought but it's claimed in the article you linked

How does this affect gps, does the ionosphere cause a delay to the signal as it passes through?

What problem did you have? I've seen batteries last for a lot less in arctic weather, and had a laptop crash unless heated, but all of my cameras have worked without a hiccup down to around -30 celsius.

Source for apollo guidance computer system is public (github), is this the same thing?

Foveon?

I'm familiar with how color information is formed on an ordinary camera, but the Mariner pictures seem to all be monochromatic and I'd think they were taken each too far apart to be later composited into a color image. Hence the question. It's also interesting that there were only two filters. Maybe someone here knows what they were for? Not quite so - there's one sensing element for each output pixel, values for the other two color channels are constructed from values of surrounding sensels. If you're interested, pixinsight devs explain some of the possible methods here, it's not too long of a read: https://pixinsight.com/doc/tools/Debayer/Debayer.html#usage_002

Any idea what was the use of having those color filters?

Wikipedia says that it had red and green filters though, any idea what was done with them? I'm assuming the camera was too slow to enable compositing into color images.

It's basically an old tv camera type thing. I didn't know the signal was digitized for transmission back in the day, that makes sense though. What about printing? I don't see what you're after, printing pictures isn't exactly a dark art?
