Why do you capitalize “Trouble”. That’s weird.
You won’t bait me into defending the design of the STS/Space Shuttle. It was a horrible kludge, designed in a way that defied lessons learned from previous work, and STILL only crashed twice out of more than 100 flights. Meanwhile, Falcon9/Dragon works just fine, and even Soyuz is very reliable. Simply put, we DON’T have “Trouble (sic)” getting men into orbit.
Spacecraft from LEO to MEO to GEO to interplanetary space measure their radiation environment. It’s routine.
But you already know all this.
