An interesting thing about mining neutron star is that those neutron decay would indeed evaporate, but that process would be cataclysmic. A teaspoon of neutronium may weight billions (or millions, I don't remember) of tons, but once it's outside the gravitational field it will revert to protons, neutrons and electrons (and neutrinos ?), and release insane amount of energy. Dwarfing what you can do with fusion or fission bombs. Only matter/antimatter explosion can compare, but they are usually not that dense. 5 cm3 of neutronium (a teaspoon) would release 200 times the energy of the chixculub meteor. End of the world event.

Mining "a teaspoon of neutronium" is like accelerating a colony ship to "just 1% of the speed of light". They sound deceptively like small quantities but are insanely huge quantities. Even "just 1 milligram" of a substance that's virtually transparent to electromagnetism is going to be hard to collect and lift out of a deep gravity well without transforming it into other particles in the process before it has a chance to decay on its own.

One odd thing about merging 2 black holes is that the resulting black hole has less mass than the 2 original ones combined.

Perhaps one-day humanity can even capture photons of Hawking radiation, and then we can say that we have observed light coming from the black hole itself, the light which can not escape the black hole, but did so nevertheless. This process, as far as I understand this, is thought to continue til the event horizon disappears and all the matter which has fallen into it has exited once again. But yes, what happens with information in this process? If a black hole swallows matter and spits it out again later in the form of Hawking radiation - has all the original information really been destroyed, and does that mean that Hawkin radiation carries no information away, although it carries mass away?

As was pointed out decades ago by engineers such a Robert A. Heinlein to deliver a useful payload to space requires a greater specific Impulse/effective exhaust velocity than can be achieved with any chemical fuel. Look up the Rocket Equation and apply the theoretical energy that can be extracted from the combustion of hydrogen and oxygen. That produces an ISp of about 450 and therefore an effective exhaust velocity of 4.45km/s. But you must achieve over 8km/s just to enter low Earth orbit (LEO).

The major reason that JWST cost $10B was because of the efforts that had to be made to squeeze the capabilities into something that could be delivered by the Ariane 5. JWST is self sufficient for ten years. Long before it dies SpaceX Starship will be in operation. Starship can deliver TEN copies of JWST and its payload bay is so wide that they would not have to be designed to unfold, and they could have twice the propellant capacity each.

(Re: Belos 33:01) A double-planet exoplanet, vs an exoplanet with an exo-moon... the methods to find those 2 classes of objects would seem similar. Things like, either seeing multiple transits grouped together, seeing transit timing variations from the planet being pulled by its partner or moon, or seeing transit duration variations from the same... all 3 of those methods seem just as applicable to both classes to me. But if we apply those methods to look for both, which one will we find first? A double-planet exoplanet would seem easier to spot, assuming they exist in great enough numbers for there to be one in our sights. However, just from how many more moons there are in our solarsystem, I would expect exomoons, though harder to spot, would be in greater enough numbers that we would spot one of them before we find a double-planet exoplanet, but we won't know until we look hard enough

How do you think the recent drama over Mars Sample Return might effect prospects for launching a Uranus mission in the early 2030s? Should I abandon hope for an Ice Giant flagship mission in my lifetime?

Sadly it's rare to find a job that you love that can also pay the bills. I'm deep into my career, it pays well, I theoretically do cool things (AI applications) but it's not my TRUE passion (horticulture). But, plants don't pay the bills, and never will.

How feasible is to launch space probes that orbit the sun, but perpendicular to the plane of the ecliptic? What kind of missions would this be good for? I imagine it would help with asteroid tracking so we can more easily see big rocks heading toward Earth from the direction of the Sun.

Will the JWST be able to do any science when it runs out of fuel and it has only electric energy?

Cheleb for a great answer. Black holes are creepy. What even IS this surface that is spinning?

There is no actual material surface. It's only curved spacetime.

Is an orbit inside an event horizon possible or stable? If it is, perhaps there is a civilization that can fully observe the singularity. Paradoxically, perhaps the most advanced civilizations are never to be found because they are inside the event horizons of black holes!

An absence of double planets but a plethora of rogue planets. Hmmm.
