> I mean how do you transfer that amount of data at this long range without loss?! Is that even possible?

Yes: https://www.nasa.gov/press/2013/october/nasa-laser-communica...

Also of interest, we see 0.5-4 mbit/s to Mars with the MRO: https://mars.nasa.gov/mro/mission/communications/

So it would take a few hours but one could transfer one of those images to/from Mars using tech that's been deployed for 13 years.
