- 0:15Speaker 1: Pushkin. Hey, it's Jacob Goldstein and this is a special
- 0:25Speaker 1: bonus episode of What's Your Problem. The problem we're going
- 0:29Speaker 1: to talk about on the show today is amazing and delightful.
- 0:33Speaker 1: How do you build a car to drive on the
- 0:36Speaker 1: literal moon for real? My guest is Eddie Alterman, the
- 0:41Speaker 1: former editor in chief of Car and Driver and the
- 0:43Speaker 1: host of a new podcast called Car Show. Amazing name.
- 0:48Speaker 1: Hi Eddie A Jacob. Thanks for having me. Yeah, thanks
- 0:52Speaker 1: for coming on. I'm very excited about your show. Can
- 0:54Speaker 1: you give me the like, very brief elevator pitch for
- 0:58Speaker 1: Car Show? Yeah? So, Car Show is about why we
- 1:01Speaker 1: drive what we drive. It's not about horsepower and milesburg Gallen,
- 1:07Speaker 1: And it's not a sort of comparison test show. And
- 1:11Speaker 1: it's not, you know, two guys throwing verbal wrenches at
- 1:15Speaker 1: each other. It's not two guys arguing over the fence.
- 1:18Speaker 1: I think it dovetails really well with what you do here.
- 1:21Speaker 1: You know, it's about the problems associated with producing something innovative,
- 1:28Speaker 1: doing something new. It is that innovation that lasts, and
- 1:32Speaker 1: those innovative cars are the ones that sort of fix
- 1:35Speaker 1: themselves in the culture, and those are the breakthrough cars
- 1:39Speaker 1: are the ones that we're going to look at both
- 1:42Speaker 1: how they came to be and then what their cultural
- 1:45Speaker 1: impact was. So I love the episode about the lunar rover,
- 1:52Speaker 1: which is basically a car, right yeah, I mean it
- 1:56Speaker 1: looks like a jeep. You've probably if you're listening to,
- 1:58Speaker 1: probably seen pictures of the guys driving on the Moon
- 2:00Speaker 1: right right in their space suits and they've got the
- 2:04Speaker 1: you know, the satellite dish and those wild men schwire wheels.
- 2:10Speaker 1: There are two different models of the lunar rover, right,
- 2:13Speaker 1: there's the first one that we built, that engineers built,
- 2:16Speaker 1: like what is it now, fifty sixty years ago when
- 2:18Speaker 1: when people went to the Moon for the first time. Yea,
- 2:21Speaker 1: So part one of the show is going to be
- 2:23Speaker 1: you telling me that story, and then part two of
- 2:26Speaker 1: the show is sort of excitingly, engineers are right now
- 2:29Speaker 1: today building a new lunar rover, a new car to
- 2:33Speaker 1: drive on the Moon for the next you know, for
- 2:35Speaker 1: this planned new mission to the Moon. So so let's
- 2:39Speaker 1: start out with the with the old lunar rover, right, like,
- 2:43Speaker 1: just what just get me into that story? What are
- 2:45Speaker 1: we It starts in what the fifties, the early sixties.
- 2:48Speaker 1: Must be the sixties. It's the sixties, and the timeline
- 2:51Speaker 1: was very, very tight. Um. What they found was the
- 2:58Speaker 1: earliest Apollo missions were really limited in scope by how
- 3:04Speaker 1: far the astronauts could travel. You couldn't really terry yeah,
- 3:09Speaker 1: exactly exactly. It took a lot of energy, they didn't
- 3:13Speaker 1: have a lot of air, and so they couldn't really
- 3:17Speaker 1: do science up there. They couldn't really interrogate the surface
- 3:20Speaker 1: of the Moon. And now the idea of having a
- 3:24Speaker 1: car on the Moon, it's kind of ridiculous. Right, we're
- 3:27Speaker 1: already at the moon, right, do we really need a car? Well,
- 3:31Speaker 1: the funny thing is you do to do real science,
- 3:34Speaker 1: you had to go past the radius of walking exploration.
- 3:40Speaker 1: So we're gonna do this kind of ridiculous but apparently
- 3:43Speaker 1: useful thing, build a car to go to the Moon. Like,
- 3:46Speaker 1: where do you even start? Well, the first problem is
- 3:49Speaker 1: how do you even test the thing? Okay, you're designing
- 3:54Speaker 1: a vehicle for a one six gravity environment, but do
- 3:58Speaker 1: you have Earth mass astronauts that have to sit in it?
- 4:02Speaker 1: And if they sit in it, they'll crush it, So
- 4:05Speaker 1: you couldn't drive it beforehand. So they built the vehicle
- 4:08Speaker 1: that was like optimized to drive on the Moon in
- 4:10Speaker 1: one sixth gravity and be super light. But that means
- 4:13Speaker 1: that like literally if the astronauts just sat in the
- 4:16Speaker 1: driver's seat on Earth, they'd break it, that's right, they
- 4:19Speaker 1: would crush it. So it's like a crapshoot. It's like,
- 4:22Speaker 1: what we hope it works. There was no test drive,
- 4:26Speaker 1: so okay, so they build this thing with no test drive,
- 4:29Speaker 1: and then and then you've got to get it from
- 4:33Speaker 1: from Earth to the Moon, right, like a whole car.
- 4:36Speaker 1: You've got to get it to the Moon to love
- 4:37Speaker 1: with the astronauts. Yeah, so they originally when they wanted
- 4:41Speaker 1: to send a car up, they wanted to send two
- 4:44Speaker 1: lunar modules. But the budget was two lunar modules, meaning
- 4:49Speaker 1: two spaceships. Two spaceships, one one for the guys and
- 4:52Speaker 1: one for the car. One for the guys and one
- 4:54Speaker 1: for the car, like a garage, like a garage in
- 4:57Speaker 1: space where you park your car, a flying garage to
- 5:00Speaker 1: take the car, because you've got to put the car
- 5:02Speaker 1: somewhere right, and it's a little space ship. But the
- 5:04Speaker 1: guys are in right, so that you know you've got
- 5:07Speaker 1: this lunar module that's got all this stuff. Minute, where
- 5:09Speaker 1: are you gonna put a car? Yeah? So okay, so
- 5:13Speaker 1: so do they do that? And so the original design
- 5:16Speaker 1: had six wheels, and they thought, okay, we can package
- 5:19Speaker 1: this six wheel vehicle because that'll be great for crawling
- 5:23Speaker 1: over stuff. You know, six wheels, there's always you know,
- 5:26Speaker 1: some contact with the terrain, bumpy if you're up on
- 5:30Speaker 1: a crazy rock something still rolling pushing against the moon. Right,
- 5:34Speaker 1: there's highly articulated sort of space spider. Right, that was
- 5:39Speaker 1: gonna gonna crawl over stuff and could get over anything.
- 5:43Speaker 1: A space spider. I mean, what's not to love about
- 5:45Speaker 1: a highlight insulated space planet. Right, budget gets slashed, They go,
- 5:52Speaker 1: we can't send two lunar modules. We can always send one.
- 5:55Speaker 1: We're not going to send a garage to the moon.
- 5:57Speaker 1: But we still need the car, right, okay, okay, this
- 6:01Speaker 1: is a good problem. Still want to You've got this
- 6:03Speaker 1: little space ship full of guys and stuff, and you've
- 6:06Speaker 1: got to find a place to put a car in it. Exactly.
- 6:09Speaker 1: So it's the old problem. How do you get the
- 6:11Speaker 1: stroller in your trunk? Right? You fold it up. So
- 6:16Speaker 1: they did that with the with the Rover, they built
- 6:18Speaker 1: a car that folds up yes. So first thing they
- 6:22Speaker 1: did was they need to downsize it a little bit,
- 6:25Speaker 1: so they went from six wheels to four wheels, even
- 6:27Speaker 1: more like a traditional car. Yes, And then they figured
- 6:31Speaker 1: out how to fold it like a business letter, like
- 6:34Speaker 1: in thirds really like it like it like or like
- 6:39Speaker 1: a maybe like an accordion kind of, I mean yeah, yeah, yeah,
- 6:43Speaker 1: like the one axle flop over onto the main section
- 6:47Speaker 1: where they would sit. The other axle would flop on
- 6:49Speaker 1: top of that, and they'd stuff it into the belly
- 6:53Speaker 1: of the of the single lunar module. So then you
- 6:56Speaker 1: take it out of basically the belly of the lunar module,
- 7:00Speaker 1: you unfold it, you hop in, and you start driving
- 7:04Speaker 1: around and did it? Did it work? Is this what
- 7:06Speaker 1: actually happened? Yes, it worked. It was right. So I
- 7:11Speaker 1: know in the story there's this moment you talk about
- 7:14Speaker 1: where everything's going fine, but then something goes wrong. Right. Yes,
- 7:19Speaker 1: Up on the Moon they run into a problem. The
- 7:22Speaker 1: first mission that had a lunar rover was Apolo fifteen. Okay,
- 7:28Speaker 1: they unfurl the thing, they roll it onto the surface
- 7:31Speaker 1: of the Moon, and then the steering doesn't work. So
- 7:36Speaker 1: they got a lemon. Right, So the steering doesn't work,
- 7:41Speaker 1: and is that the end of that? Do they just
- 7:43Speaker 1: not drive on that mission? It magically connects and they're fine. Okay,
- 7:47Speaker 1: so they're driving around. It works itself out. A little
- 7:50Speaker 1: electrical glitch that works itself out. Not a big deal,
- 7:54Speaker 1: but sort of a harbinger of things to come. On
- 7:57Speaker 1: Apollo sixteen, Okay, the next mission, astronaut John Young has
- 8:04Speaker 1: a hammer in his pocket on his space suit, as
- 8:07Speaker 1: one does, and he walks past the lunar rover and
- 8:12Speaker 1: the hammer snags itself on the fender of one of
- 8:16Speaker 1: the rear wheels and it rips the fender off. Okay,
- 8:20Speaker 1: not a huge deal on Earth, right, Sure you see
- 8:23Speaker 1: people driving around with that offender exactly, but these have
- 8:27Speaker 1: sort of like motorcycle fenders. He rips this thing off,
- 8:30Speaker 1: and now he's driving around on the Moon and he's
- 8:33Speaker 1: kicking up a huge flume of moon dust, which is gritty,
- 8:38Speaker 1: not really good for the equipment, the space suits. This
- 8:44Speaker 1: gritty moon dust gets into everything, and the fender was
- 8:47Speaker 1: supposed to sort of keep that dust from spraying up, right,
- 8:50Speaker 1: That's what the fender is there for, And now the
- 8:52Speaker 1: fender is not doing that, so there's getting everywhere. So okay,
- 8:56Speaker 1: so there's dust everywhere. What happens? Okay, so it starts
- 8:59Speaker 1: getting into the electronics and things start overheating, and it's
- 9:04Speaker 1: getting into the O rings on their space suits and bad,
- 9:08Speaker 1: not just for the call are but for the astronauts.
- 9:10Speaker 1: Oh yeah, like really bad. And so what do you do?
- 9:16Speaker 1: There are no repair shops on the moon. Right, he's
- 9:20Speaker 1: got a hammer. We know he's got a hammer. That
- 9:22Speaker 1: he's got a hammer. And you know what else they had?
- 9:24Speaker 1: They had duct tape. No, okay, yeah, they had it
- 9:29Speaker 1: with duct tape. They fixed it with duct tape. They
- 9:33Speaker 1: took geologic they took the geological maps that they had
- 9:40Speaker 1: in the rover, folded them together into a you know,
- 9:44Speaker 1: sort of makeshift fender extension and duct tape. Ton that
- 9:49Speaker 1: is dynamite. Isn't it awesome? And it worked and they
- 9:53Speaker 1: just kept driving around the Moon. That's right, That's exactly right.
- 9:56Speaker 1: Let me say, Eddie, thank you for coming talking to
- 9:59Speaker 1: me about your new show. Thank you, and let's play
- 10:02Speaker 1: now a part of your new show of car show.
- 10:05Speaker 1: NASA's planning a new mission to the Moon, and people
- 10:08Speaker 1: right now are design a new car to drive on
- 10:11Speaker 1: the Moon. So let's hear that NASA's Artemis program plans
- 10:15Speaker 1: to get us back to the Moon for the first
- 10:17Speaker 1: time in fifty years. The current timetable has Americans landing
- 10:21Speaker 1: on the Moon in twenty twenty four. NASA plans to
- 10:24Speaker 1: put a permanent colony on the Moon and use it
- 10:27Speaker 1: as a platform for travel to Mars, and once again,
- 10:31Speaker 1: General Motors is busy at the drafting table. But unlike
- 10:34Speaker 1: those early Apollo missions, the goal this time around isn't
- 10:38Speaker 1: just about exploration. What's really interesting about this particular series
- 10:42Speaker 1: of missions is that the intent is a long term habitation,
- 10:46Speaker 1: or a colonization of the Moon, if you will. That's
- 10:49Speaker 1: Jeffrey Neil who's working to design the new lunar rover
- 10:52Speaker 1: for Artemis. So yes, perhaps we'll get our vacation homes
- 10:56Speaker 1: up there. Yet we may be a two planet species,
- 10:59Speaker 1: after all. Elon Musk wants that second planet to be Mars,
- 11:04Speaker 1: not the Moon, but Artemis posits the Moon as a
- 11:06Speaker 1: launchpad for Mars exploration too. We're going back to the Moon,
- 11:11Speaker 1: and this is why the Moon is a treasure trove
- 11:16Speaker 1: of science. It holds opportunities for us to make discoveries
- 11:20Speaker 1: about our own planet, about our son and a bottle
- 11:23Speaker 1: solar system. The wealth of knowledge to be gleaned from
- 11:27Speaker 1: the Moon will inspire a new generation of thought and action.
- 11:31Speaker 1: Without fail, every major program and mission NASA has invested
- 11:35Speaker 1: in has led to technologies and capabilities that have shaped
- 11:38Speaker 1: our culture. The breakthroughs of the Artemis era will define
- 11:42Speaker 1: our generation. The Moon also makes an interesting proving ground
- 11:45Speaker 1: for streets on Earth. The new rovers are electrified, as
- 11:49Speaker 1: the first ones were, but that line of electric vehicle
- 11:52Speaker 1: development stopped with Apollo. Hopefully what the Artemis team finds
- 11:57Speaker 1: out about batteries and motors can be applied down here.
- 12:00Speaker 1: I think that having the lunar surface or the lunar
- 12:03Speaker 1: environment as a proving ground is certainly a wonderful opportunity.
- 12:08Speaker 1: The solution is that are effective in that challenging environment
- 12:11Speaker 1: will absolutely push our knowledge in our technology in the
- 12:15Speaker 1: direction that we could then therefore apply back on Earth.
- 12:19Speaker 1: You have a pretty unique thermal environment there. All you
- 12:22Speaker 1: ev owners out there know what I'm getting at. When
- 12:26Speaker 1: it's cold out, you'll lose driving range, lots of it. Yeah,
- 12:30Speaker 1: So there's a huge shift in temperature the lunar surface
- 12:36Speaker 1: when it's when it's daylight is two hundred and fifty
- 12:40Speaker 1: degrees fahrenheit. When it's the equivalent of nighttime, it's it's
- 12:45Speaker 1: two hundred and fifty degrees fahrenheit below zero. So that's
- 12:49Speaker 1: a massive shift. We don't really experience anything quite like
- 12:52Speaker 1: that here. And the lunar night lasts for the equivalent
- 12:56Speaker 1: of fourteen Earth days, so it's a very long night,
- 13:00Speaker 1: a very long day, very cold night, very hot day.
- 13:03Speaker 1: One of the things that we're working on is obviously
- 13:06Speaker 1: solar charging. That's that's they're going to be the source
- 13:09Speaker 1: for this vehicle. There's nothing to plug into up there,
- 13:13Speaker 1: and we're developing what's called a solar array, and this
- 13:17Speaker 1: will pull energy from the sun and it will store it,
- 13:20Speaker 1: and our goal is to survive the lunar night. We're
- 13:25Speaker 1: intending for these vehicles to be able to live on
- 13:27Speaker 1: the lunar surface, so they have to absorb fourteen days
- 13:30Speaker 1: of heat and light and then use that to survive
- 13:33Speaker 1: fourteen days of cold and darkness, and then repeat over
- 13:37Speaker 1: and over and over and over again. So this rover
- 13:45Speaker 1: would be of unlimited use. You could go as far
- 13:49Speaker 1: as you want because it's rechargeable. It's also recyclable. The
- 13:53Speaker 1: idea is that these are not one time use disposable
- 13:58Speaker 1: mobility vehicles. These have to have a lot of durability
- 14:01Speaker 1: and longevity. We've thought a lot about you know, we're
- 14:04Speaker 1: in a situation now where we're having conversations about repair
- 14:08Speaker 1: long term and repair our parts inventory. It's not a
- 14:12Speaker 1: one used case situation like Apollo. We've even talked to
- 14:18Speaker 1: the team about the interchangeability of the parts. The intent
- 14:23Speaker 1: is to have more than one of these rovers on
- 14:24Speaker 1: the surface at any given time. I mean, we're thinking
- 14:27Speaker 1: about maintaining a fleet of vehicles over a long period
- 14:29Speaker 1: of time, and the more we can share between this
- 14:33Speaker 1: fleet of rovers, the better we're going to be. Yeah,
- 14:36Speaker 1: it's funny because you know, the Apollo programs were sort
- 14:39Speaker 1: of use it and leave it, and then the Space
- 14:44Speaker 1: Shuttle is a reusable service craft. And now you look
- 14:48Speaker 1: at what euon Musk is doing, and those vehicles intercept
- 14:54Speaker 1: the space station, they come back and they land on
- 14:57Speaker 1: the pad, and sustainability and reusability seem to be all
- 15:01Speaker 1: of a sudden the keywords of the space program. So
- 15:04Speaker 1: it's really cool to hear that we're not just using
- 15:07Speaker 1: it and dumping it on the moon because there's three
- 15:12Speaker 1: cars there already. All right, I can't wait for the
- 15:16Speaker 1: photo of the new Rover and the old Rovers. A
- 15:21Speaker 1: great idea. Do you hear that? Everybody, We're going back
- 15:26Speaker 1: to the moon. That was a clip from Pushkin's newest podcast,
- 15:45Speaker 1: Car Show exclamation Mark with Eddie Alterman. Other episodes of
- 15:50Speaker 1: the show include stories about a car that defied gravity,
- 15:54Speaker 1: the best sports sedan ever made, and also how the
- 15:57Speaker 1: minivan changed America. It's true it did. You can find
