Weirdly the males in turn have much wider hips than you'd expect. Do the females actually give birth, or are kerbals like seahorses?

There's nothing preventing oxygen-rich SC engines from having relatively long service lives. RD-170 was designed to last at least ten flights, and NK-33s have gone through multiple series of test firings.

That doesn't make any sense; everything was going well, until something happened within the turbopump.

It would emit plenty of neutron radiation, which would produce radioactive material.

In terms of categorisation, it's exactly the same system. Changing a few names isn't going to make any system 'more efficient'.

A problem would be that can be harder to determine than you might expect. For example, here's an image, at about the best quality we have available, of Jupiter's fifth-largest moon Himalia; round enough or not?

RD-170 is the engine on Zenit's first stage, it's flown dozens of times.

Orbital have put out a press release with some preliminary findings; it was 'probably' a turbopump failure, and they will 'likely' discontinue use of AJ-26 as a result. Given the time engine replacement and pad repair will take, they plan one or two launches of Cygnus on another rocket in the interim. They've separately stated the other launchers they're looking at are from 2 US and one European operator, meaning they can't really be anybody other then spacex, ULA, and Arianespace.

I'm not sure about the colour, but the contrast is very heavily enhanced. The imaging team compared it to taking images on a tarmac car park at midnight.

This is just an industry show exhibit, right? You can find moon base models for multiple countries produced under similar circumstances. While there probably is a plan for Mars missions in the near future, I highly doubt this thing has any real connection to it.

It's near-infrared. Any true colour image of Titan is a fuzzy orange ball.

It turns out it's what was done in the . It seems the supposed 'standard operating procedure' is anything but.

The pyramids are big piles of rock with almost no internal space, and the great wall of china is a series of perfectly normal medieval boundary walls that happen to be really long. They don't show any intelligence, just concentration of power and resources.

The precise opposite here. Put my own PC together a few days ago, but couldn't program anything in any language.

I'd go for Nexus 6, solely for the potential for Blade Runner references.

They wouldn't have a chance. Complete breakup was within the next couple of seconds of pulling the lever. Either they did it while panicking, remembering recommendations to use it in case of loss of control in earlier glide flights, or they were intending to turn off the motor before actually activating the mechanism.

When thinking about diet, it must be remembered there are only two things Kerbals could potentially be eating; A) sunlight or grass Either could explain a green colour, in the absence of other pigments; and why would they have pigment, in an ecosystem with no predators or competitors?

The feathering mechanism has been emphasised as a safety feature before, and SS1 escaped a spin by feathering on at least one occasion. It's very likely the attempt at feathering was in response to another problem, but exactly what it might have been isn't clear at that point.

Does 'Titan family' include Thor?

Both are dependent on the specific conditions. Improvements from aerospikes depend on the chamber pressure; Pressure-fed engines could see dramatic gains, and something like RD-170 and it's descendants would not benefit at all.

Do you actually play KSP? You can't just drop things from orbit, detection times and chances of intercepting a deorbiting nuke won't be much different from one on an ICBM, and would have required a much larger rocket to put there in the first place. The only actual attempt to put weapons into orbit was so the soviets could exploit a hole in US missile early warning radar coverage, but that hole no longer exists. Large parts were dummy, including the laser.

What advantage would any nation gain from orbital nuclear weapons?

They aren't the only actors in this area. Jeff Bezos' Blue Origin have reached all of these points already; they've built a test suborbital tourism vehicle, they've developed an engine for it that both actually works and has utility for orbital spaceflight, and they've had their test vehicle turn into tiny pieces over the desert. They'd bothered to include an autopilot in their vehicle of course, so they're continuing with barely a blip.

The ONLY thing illegal up there would be 'full blown nuclear weapons'. There are no treaties that ban any conventional weapons in earth orbit, except the Moon Treaty, and no nation with orbital capability has ever ratified it.

Somebody else had already had that idea, it's called LANTR.
