Can someone explain the significance of this event? People have visited the moon before so why is this event important? I mean I guess it’s cool but we’ve seen it happen over and over in the last 50 years.
How can they stream such high quality footage from space?
What is Starlink? How will it work?
How did Falcon 9 return to the recovery unit? Was it gps guided? I thought it would’ve landed in the ocean to be retrieved by a crew.
Why have we made so little progress since landing on the moon back in the 1969. I understand that this is the first commercially made spacecraft, and that it’s the first manned US flights in 9 years, but with the incredible progressions in technology between 1969 and now, why are we now behind where we were?
Why are rockets built to go off in stages? what are the benefits?
