This has a more detailed description of the flight. But yeah I’m assuming it’s gotta be super efficient because it’s using a falcon 9 and they’re re-entering the boosters which further reduces its max payload.

As far as I know, this is more because of fuel requirements on a tiny lander. If you go to the moon in 3 days, Apollo/Orion style, it takes a lot of fuel to slow down and enter orbit. This long trajectory however is low energy and saves up on a lot of fuel. Too bad we have to wait so long, lol.
