Can we predict evolution?

Image above: Glowing corals entice nutrients like small water insects.  Why are species advancing? The reason for that is that the species must get nutrients. And they must get descendants. The challenge is that if the species is good prey for hunters it dies before it can make descendants. If the hunter is too dominating, it eats its food to end. And that thing can cause extinction. Same way, if some animal is a too easy target. That causes extinction.  For success, the species must ensure its nutrient source. Without nutrients, the species is gone. So, that's why corals are glowing. Glowing corals are a good example of how a thing that seems meaningless has a big role in evolution.  When we think about the reason why corals glow, we can answer that the glow of corals is meant to entice food. Because bioluminescence increases the nutrient level of corals higher than corals that are not glowing, that makes glowing corals stronger. And they will take over space from other ...

MOXIE successfully made water on Mars

Mars is far away from Earth. And if the researchers can make something necessary on that planet, that thing makes all missions to that planet easier. The oxygen is needed for breathing in manned missions. But also oxygen is needed in unmanned missions.  It can use in fuel cells that making possible to operate at nightside without nuclear systems. The water can break into hydrogen and oxygen which are excellent fuel for rockets and fuel cells. Those systems can also decrease the need to use nuclear systems.  The solar panels can use to split water into hydrogen and oxygen. And that kind of system is decreasing the need to use nuclear fuel. So nuclear reactors can work longer before operators must change the nuclear fuel elements. This makes those missions cheaper.

Or at least that rocket is based on the technology developed for the Lance mi...
