Hedgehogs are nocturnal. Humans mowing lawns tend to do so in daylight so few problems, but I suspect people may set the robot mowers to run overnight when the hedgies are out and about foraging.
I think it was a Jack Vance story where part of the background was that you could set whatever value on your property you wanted, but anyone could buy it for three times the amount you set whether you wanted to sell or not.
There has probably been a lot going on in the background to try and sort things out. That hasn't worked so it's now turned into a public "Fix this or else" situation. Ultimatums are rarely the first means of redress.
You have to wait until a satellite is in the right part of its orbit to take the images and possibly wait again until it is in position to download. An aircraft can be scrambled, flown over the point of interest and return the imagery at much shorter notice.
The oldest tunnel still in use under the Thames in London is coming up to its 175th birthday, half of them are over a century old and still dry. It's not that hard.
The aero engines Rolls Royce are a separate company to the car makers these days, and BMW just own the car bit. They've got various agreements between the two for use of the badges and names so it could be either, both or neither have IP for the Merlin.
So you thini there's somehow a natural right for some private entity to be given access to infrastructure they did not build so they can make a profit because...I can't even make up a because here.
Who's *giving* them anything? They can *buy* access, and the entity that installed the infrastructure can then recoup their costs and maintain it. Seems to work perfectly well in the UK.
NASA were working on the TransHab module for the ISS which got killed by the US Congress. Bigelow picked up the work and have turned it into actual orbiting items.
If we're going to talk about getting the facts right, the World Service has been funded through the licence fee since last year with a relatively small top-up from the government announced back in November.
Basically you need a third object to get involved, for instance it's thought that Triton was one of a pair of similar sized objects in orbit around each other. Triton was (relatively) going backwards at the time of a close approach so landed up in orbit around Neptune, it's partner got slung away. That also seems to explain why Triton is in a retrograde orbit.
The liquid is a camera inside the second stage fuel tank, last launch they were showing it after the engine cut-off and you had large blobs of the stuff floating round inside. The black and white camera appears to be a thermal infra-red looking at the second stage engine nozzle.
And the RTG itself isn't all you need. You need decent sized radiators to dump the excess heat for a start.
An RTG would have eaten somewhere between a third and half the mass available for science instruments, and you'd have quite a lot of excess heat being dumped into the surrounding environment which would distort the readings being returned.
It's what SpaceX are currently calling the BFR will switch to Methane instead of Kerosene. The Falcon Heavy is effectively three Falcon 9 stages in parallel, similar to the existing Delta IV Heavy but with added fuel cross-feed. With cross-feed the core stage will still be fully fueled when the boosters detach.
Methane has the advantage it doesn't need the tank to be pressurised with Helium, a bit of excess heat can be diverted back into the tank to boil off enough to keep the pressure up. The current Helium pressurisation has been giving problems and accounted for a few launch delays because of leaks. The tank needs to be bigger, but overall complexity drops.

Something like this?

Nineteen Russian satellites? Well, including the 12 American, the Canadian one, the Norwegian one, two from Sweden and the one from Germany that is...

Sputnik 1, Sputnik 2 and Explorer 1 had all successfully launched into orbit before Vanguard 1C joined them.
Note that the jet hours requirement in that document is from 2004 and applied to Commanders and Pilots only, not Mission Specialists.
Lemmy died a year ago tomorrow so if we treat him as the first then tonight's New Years Eve.

That's the plan. It may be possible for some launches to have all three come back to dry land if the payload is at the low end of capabilities.
...Goes the weasel.

No, the spiders are from Mars, not the moon.
Eventually, bad people will get that key
Surely not?

..Having ignored the trivial detail that Rosetta is an ESA mission and was launched on an Ariane 5.
