and basically takes controlled falling back to Earth to recover.
You underestimate what it takes to control a fall back to Earth. You would have to package the payload in a capsule. You can either take that capsule all the way to the Moon and back (like in the Apollo program), or you have to do a rendez-vous in LEO, which requires building (or refurbishing) a capsule, launching it to LEO, orbital matching of payload and capsule, and performing autonomous loading procedure. Orbital matching means that your payload needs thrusters and navigation.
Anyone can do the math and see that it might make a lot of sense to try mining valuable minerals from space objects now, and if not certainly within 10 years it will be easily viable.
Oh, you're doing math ? Let's see then. I agree that launching a small satellite on a F9 is more affordable now, but that Israeli lander is still quite far away from doing anything profitable on the Moon.
So, what would it cost for someone to actually mine stuff from the Moon, and send the materials to a buyer ?
The correct way to fix that is to change what time school and work starts. Not to change everyone's clocks
Except that it's much simpler to change the clock than to change every schedule, or worse, only part of the schedules.
If you insist on changing the clocks, everyone is affected - even people in areas where the time change offers no benefit and is tremendously inconvenient.
Then those areas can choose not to change the clock.
Previous efforts had been to establish Standard Time year round, but it turns out people prefer that hour of sunlight in the evening rather than the morning.
Until they've experienced long mornings without sunlight, and then they'll miss it.
I should add that no one, literally NO ONE I know wants to continue with the DST bullshit
When most people think about DST, they only think about the disadvantages of the transition, but they don't consider the advantages. Ask them again when it's abolished.
They decided not to pursue the thruster landing because it would require a lot more effort to prove its safety. A parachute landing is based on well known technology. They may still do it at a later time.
After landing the Dragon capsule will be reconfigured for cargo only. I guess they can take the seats out and reuse those in another capsule, but they could already do that with any other capsule.
Start with some sever fines or jail time for people who intentionally sabotage recycling and you won't see christmas trees and sofas in the recycling anymore.
That is demonstrably false. Forcibly sleep-deprived animals (and people) die much sooner than they deplete their stored (as fat) energy reserves.
That's because they've evolved to become dependent on sleep/wake patterns. Once an organism goes to sleep every night, it makes sense to optimize their biochemistry by doing some tasks only during the sleep cycle.
many animals are nocturnal, and many archaic animals live in the dark depths of the sea without light, so your answer doesn't hold
That depends on how these animals evolved. Here's my hypothesis:
1) sleep evolved to save energy 2) once sleep cycle was introduced into organism, evolution modified biochemistry on various levels to take advantage of sleep/wake cycle. 3) organism becomes dependent on these modifications, even after evolving to new habitats.
That would depend on the energy difference between staying alert and sleeping, and the chance of getting attacked by predators, and your ability to spot them in the dark. Also depends on the sleeping patterns of the predators. Some animals (e.g. ducks) do indeed stay more alert than others.

Problem with that scenario is you still need an end product that is profitable. There is no market for huge solar arrays in space.
Price of a kg of iron at GEO: $12,000

Nothing is stopping you from leaving your clocks alone either.

Likewise, we've seen no evidence that she did anything at all wrong.
Why should we ? It's a private matter, and we are not part of this case in one way or the other.

so change the time your school starts if it means so much in your district
That's much more impractical, especially for those trying to mesh work schedule with school schedule.

2nd link says this: "The images were captured during the fourth phase of Air-to-Air Background Oriented Schlieren flights, or AirBOS"
A simple solution is that the company who's selling the product provides free legal counsel by chat or phone to clear up any misunderstandings.
Another asshole who thinks he's a lawyer. You are WRONG WRONG WRONG. Not reading a contract is not a defense.
The contracts are designed to be unreadable by someone he's not trained as a lawyer, so we're fucked either way.

My motto is: when in doubt, throw it in. The men that come pick up the bags of plastic recycling aren't going to do a chemical analysis.
Why would a glass vase be recyclable but a glass coaster not be?
Coaster could be made from borosilicate glass, and they don't want that to end up mixed with regular glass.
Start with some sever fines or jail time for people who intentionally sabotage recycling and you won't see christmas trees and sofas in the recycling anymore.
That requires catching them first.
It is almost like they could use their criterion for "fake account" to their own advantage.

Except we don't really save much energy by sleeping and we expose ourselves to danger
What do you mean by "we" ?
Are you talking about humans, or about all organisms with a sleep/wake cycle ?
