[Interview+] Getting to the Moon Is Much More Complex Than You Think

We're pretty familiar with orbits around the Earth. But as we start putting more and more things on the Moon, it means we'll need to cover more and more orbits that go to and around the Moon. And it's actually much trickier than you think.

Doesn’t seem to grasp how Newtonian telescopes work
Thankyou for giving us insight into something so interesting.It almost is at the stage where we need intergalactic garbage ships like in Red dwarf.Thanks.lbd
That was a really interesting interview, enjoyed it immensely.
Professor's studio photo and his real face were so different it threw me off 🤣 but glad I stayed, very nice discussion and please don't do this bait-and-switch on next guess, Fraser. lol
I think I’ve posted this before but I’ll “risk” posting again: The most valuable work coming out of Universe Today are these interviews. I get so much value out of being a supporting Patron!
Very, very interesting interview. I had no idea there were so many ways to get to the moon. Some of the orbits are fascinating. Have you ever conducted an interview with anyone who is studying the viability of space elevators in their various guises? I realize earth upwards elevators are not yet viable but moon orbit down elevators seem do able with current materials. I imagine even a rope ladder "dropped" from a moon orbiter would work. Is anyone studying this seriously?
No that is still too-fast for a "landing" even from Moon-synchronous oribt, best to do a drop with rocket controls, and later, a "landing" with rocket controls, no air mean no parachutes.
What a kick-ass discussion! Thank you, Fraser Cain, for reaching out to Aaron Rosengren, and to Aaron Rosengren for taking the time to offer us his insights.
Fascinating interview! Thanks Fraser!
Very cool interview. I now realize how little I understood orbits. Thanks Dr. Rosengren.
