Never heard of your first bulletin.

The second one is supposedly the reason for the artemis missions. DId they send the dummys strapped with radiation sensors yet? I remember hearing the launch was delayed but they must have launched it months ago. They may make it to the moon ok. Beyond though. I still think its strange none of the apollo astronauts didnt end up sterile. Lucky bastards.

And your third point is kinda silly. Breaking earths gravity is the hardest part. Flying from LEO is a fraction of the cost.
