41:34then we're going to do the trans lunar injection, which is this hybrid free return. What we're going to do is when the spacecraft reaches perigee, which is when it's closer to the Earth, when it's closest to the Earth, >> that's when it has the least potential energy in terms of gravity because it's close to the Earth. But that means it's moving faster, right? That's actually Kepler's second law. Yes. >> That like the closer you get, the faster you move. >> Mhm. >> When it's moving faster, that's when we want to do the burn to go to lunar orbit. This is something called the Oberth effect, which basically says that if you want to if you want to change your trajectory, the fastest way to change your trajectory is to do it when your
42:17velocity is highest because then your delta V actually has the most effect. >> Okay, so that's what they're doing. They're going to do this hybrid free return, which means they're going to go all the way to the moon and back. And they're going to do it in such a way that they're farthest away from the moon. They can see the moon and the earth. They're going to swing around. The moon is going to slingshot them back. And then if everything goes well, then the return, the total mission is going to be about 10 days. There's going to be a direct Earth entry. And the Orion is capable of doing a skip entry where it like sort of slows down with the Earth's atmosphere once and then it comes back and it lands somewhere in the Pacific Ocean right off the coast of California where we have our navy, our beautiful American Navy with the
42:59warships and the and the helicopters. They go and they, you know, pick them up. >> That's where the military comes back into >> Yes. [snorts] After we've done all the hard stuff. >> Yeah. >> Then they come and, you know, do a little quick Uber ride back home. >> Yes. Exactly. And this is not a shot like we the men and women who support it's great. It's fantastic. It's just it's an appropriations problem. Yeah. It's not a uh armed services service members problem. >> Yeah. And I mean we're going to get into the armed services when we talk about the crew because the crew a lot of them are from the armed services. So let's talk about the crew. We've got four astronauts. They've been selected for the NASA Artemis 2 mission. Commander Reed Weisman, pilot Victor Glover,
43:42mission specialist Christina Ko, and mission specialist Jeremy Hansen. And can I just say quite a goodlook >> good looking crew. This is a good-looking crew. >> This is a goodlook crew, dude. And I am sure there was someone on NASA that look I I don't know. [laughter] I don't know. But like the photogenicness of the crew, I'm sure there was someone that was like this is going to be good on Twitter. [laughter] Like this this is going to be good on
