What's important about this, is the fact they have been able to see spectral lines in an exoplanet atmosphere. Okay, so in this case they saw boring water, but if this technique can be refined to check other (smaller) planets, we can see what other atmosphere compositions we can find. Some of them may point to life.
If you can't handle a power fluctuation of a single millisecond, there's something wrong with the factory design. Short fluctuations like that can also happen with other power generation techniques.
China is growing quickly, and it would be a good plan to try to implement that growth with CO2-neutral technologies, rather than build more coal plants, only to have to replace them in a few years.
Granted, coal is sorta technically "renewable" but only on a geological scale that renders the term pointles
Actually, most of the coal was formed during the Carboniferous period, where the state of the climate, as well as the biological evolution worked together to create the perfect environment for storing large amounts of coal. The trees at that era had evolved to produce lignin, but the bacteria were not yet evolved to break it down. Similar conditions may not happen again, so we can't even be sure that new coal will form in any useful quantities.
Exploration of space and the solar system is mostly for fun. It's interesting to see what other places look like, but it's unlikely that it is going to affect us a species. Earth observing satellites will have a greater impact on that.
There are only a few and very unlikely scenarios where humans on Mars would have a better chance of survival than humans on Mars, and many likely scenarios where humans on Earth would have a huge advantage. Even something similar as the Cretaceous–Paleogene extinction event is survivable for a group of well prepared and sheltered humans on Earth, at a tiny fraction of the cost it would take to colonize Mars.
We know that nothing big has hit the earth for 65 million years, and we can also look further back. That gives us an idea of the probabilities. All in all, it's much more likely you'll get hit by a car than by a asteroid.
A high speed fiber network is a real improvement, and will benefit the economy in the future. Nothing artificial about that. And what if it takes a decade ? If you wait a few years, the upgrade will still take a decade.
The great pacific garbage patch has a density of 4 small pieces of plastic per cubic meter. You wouldn't even notice it if you were sailing through it.

Despite the fact that many objects are much further, one could argue that 20 light years isn't close.

So your plan is to use the moon as a base to explore the terribly uninteresting asteroid belt ?
Square screens are probably the only way to stop people making vertical videos.
Another solution would be to stop having children.
But they're manufactured in China using power that is primarily generated by coal
What if you buy the panels that are manufactured using power primarily generated by solar panels ?
I have regular jeans from a standard brand, and I can easily fit a 7" tablet in the front pocket. Have to take it out when I sit down, though.
The publicity is probably worth more than the phone, especially if the phone is a flimsy toy.

Las Vegas has a fucking atmosphere. If you don't mind living in the desert, there's still plenty of that down here. No need to go to Mars.
For every muslim, there's another muslim who will claim that the first is not a muslim.
space mining appears to be the most viable way of acquiring some rare substances
Which ones, and do you have a cost analysis ?
The technology is almost ready to colonise mars now
Not quite. With a lot of effort and a huge budget, we may be able to get a man on the surface, but that's a far cry from colonisation.
The problem is that people are only offered a choice between bad and worse.

10Mbps per person may be reasonable, but 10Mbps for a home is slow if several family members want to watch online videos at the same time.
Why not put the bar at something a little more reasonable, like 25 Mbps..

And if they were actually free, you'd probably hate being the one sold as a slave.
