I am not an astonomer, but I seem to recall much debate regarding the the very existence of exoplanets. Now we take their existence for granted even though they are difficult to detect. I always wondered why there was even any debate regarding the subject? Why did scientists even bothering with that particular argument?
But it is more entertainment than anything else - until we get off planet enough to test it
If something cannot be tested then it's not true even if it appears highly plausible. The existence of exoplanets was also hotly debated in the same manner right up until the first one was found. What is so far fetched about the idea behind panspermia? All of the material we see around us here on Earth originally formed inside previous generations of stars and much of it may have been incorporated into previous generations of planets. Bacteria can be found inside rocks here on Earth so why can't some very big very old rocks containing bacterial "spores" from long since vanished planets not have ended up on Earth or anywhere else within or outside of our galaxy? The universe is very very very old so life surely has had more than enough time to flourish die and spread inside rocks of any size.
There should be a "GPS license fee" for Non-US-entities who think that they have some kind of a right to GPS service which is funded by US taxpayers. I also think that most Europeans would happily pay it too just like they do for their so-called "TV licenses".
I often wonder if "environmentalists" have any real appreciation of the laws of thermodynamics or idea of the energy needs of of modern society when they take on endeavors like this. If all of society decided to run their cars off of coffee and/or wood-chips there would soon be no wood or coffee left. What kind of environmental catastrophe would that lead so?
They actually know the point of what they are saying. My birds know our names, say thinks like "thank you" when they want something, "night night" when they want their cage covered, "hello" when the phone rings, "water" when they want to be sprayed, and say "don't bark" when my dog barks.
I have noticed this with my quaker (monk) parrots. I have had sets of two over the past 25 years and what the two birds I have today was actually originally tough to previous birds I once had. It seems that they teach each other much like children teach children's games to one and other.
So it will take NASA over 10 years to launch only two more missions? So what do they plan on doing after the second launch? I'm sure by that time that Russia and China will have launched more than just two missions a piece. I really don't like the sound of this.
Living in Germany I often get the impression that most Germans (not all) know very little or nothing about what it takes to generate the amount of electricity that their heavily industrialized country relies on. The loudest protests seem to come from those on the far left who know less about the topic and are completely unwilling to listen to the voice of reason at any cost. Perhaps Germany has hidden infinite supply of unicorn dung with which they can use to power their eco-friendly organic antimatter reactors for generations to come?
