So ... is there a good explainer of why this mission is 10 days versus 6 for Apollo 8?
@adamshostack short answer is it's a longer route
@brianvastag Pretty sure the moon's in the same place, Brian :)
@adamshostack they're using something called a free-return trajectory, which means they do a single burn to leave Earth orbit and head to the moon. They circle the moon but don't orbit it and won't burn their engine again, whereas Apollo used their engine to break lunar orbit and return to Earth.
@brianvastag @adamshostack Also, they’re doing a low-Earth orbit followed by a very high-Earth orbit before heading to the moon, so it’s going to take longer
