Quote of the Week
The great enemy of truth is very often not the lie-deliberate, contrived and dishonest--but the myth--persistent, persuasive and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

Introduction

You're listening to the Skeptics' Guide to the Universe, your escape to reality.

S: Hello and welcome to the Skpetics' Guide to the Universe. Today is Tuesday, November 26th 2013 and this is your host Steven Novella. Joining me this week are Bob Novella

B: Hey everybody.

S: Rebecca Watson.

R: Hello everyone.

S: Jay Novella

J: Hey guys.

S: And Evan Bernstein.

E: Hey folks, I want to wish you all a very happy Hanukkah and a happy thanksgiving this week.

J: Thank you Evan.

R: Thanksgivingukkah!

S: Thanksgivingukkah?

E: Thanksgivingukkah!

J: Vat is this, Hanukkah? What does Hanukkah mean?

E: Jewish festival of lights!

R: Really, Jay?

J: Look I know what it means, there's people out there that don't, this is an educational show, Rebecca, come on.

E: The word Hanukkah means dedication and the name is supposed to remind us all that the holiday commemorates the rededication of the holy temple in Jarusalem following the Jewish victory over the Syrian Greeks way back in 165 BCE. But what I'd like to mention tonight is that Hanukkah is falling on, the first day of Hanukkah is falling on thanksgiving which is a rarity, in fact it's so rare that it is not...

S: How rare is it?

J: Oh ho, my god.

E: The next time that this will happen, assuming that there's no major changes in either calendar, the Jewish calendar or the Gregorian calendar, between now and then, the year 79,811 will be the next time this merging of the holidays occurs.

S: Really?

J: Wow!

R: I'd like to put my nickel down and say that there are going to be some major calendrical changes to both of those.

S: Before 70,000 AD?

E: I would think so.

R: Yeah. I assume we'll all be lizards before then. Lizard people.

J: Super-intelligent lizard people with robotic arms.

R: Yeah.

S: We'll be (inaudible)

R: We'll be in like that sort of vision of the future.

J: Like Sleestack.

E: A Jewish Sleestack. I like it.

J: Alright so I'm going to formally change my show name to Chaaka right now.

E: You got it Chaaka.

R: Can I call you Chaaka Khan?

J: You can call me Chaakadoodle.

S: Alright we're off to a bad start here, bad start.

This Day in Skepticism (2:13)

• November 30, 1954: In Sylacauga, Alabama, United States, the Hodges Meteorite crashes through a roof and hits a woman taking an afternoon nap in the only documented case of a human being hit by a rock from space.

R: And I'm sorry it's only going to get slightly more depressing. But let's take this as a celebration for this day in history I had one thing to talk about for Saturday but today that we happen to be recording which is November 26th, Tuesday, today is the birthday of Mike Lacelle who of course, long time listeners may know as probably our all-time champion biggest fan of SGU who set up sgufans.net and kept track of every episode before he befriended us and particularly you guys, you'd go visit in Connecticut and do nerdy things with and he played, we had an online guild together in Rift, the whole deal and sadly Mike passed away last year, far too soon and he will always be missed by everybody here at SGU.

J: Definitely yeah, so it was his birthday so I wrote a little note on there on Facebook. I rarely do that but I think about Mike every day and I just wanted to say something nice about him.

R: Yeah, he was a great guy.

E: He was family, there's no doubt about it.

R: So with that in mind, Mike would probably want us to go on and have an awesome show where Jay finally is funny for the first time every.

E: Silly or funny?

J: I'll do my best.

S: We can always hope.

R: Whichever, but funny would be best.

J: Oh my god.

R: As for the day that this comes out, in history, today is the day that marks the day in 1954, November 30th 1954, that was the first and possibly only documented case of a human being being hit by a rock from space. It happened in Alabama, it is now known as the Hodges Meteorite, so named after the woman who was smacked with it. It left an enormous bruise on her that can be found online, it looks quite painful. She had just been napping on her sofa in the afternoon, covered up with several blankets, when the meteorite fell and actually it was originally a much larger meteorite but a piece of it broke off and went through her roof, hit a radio, bounced off of it, and hit Hodges as she napped on the couch. So she was badly bruised but able to get to the hospital herself to have it checked out and what followed was a custody battle over the meteorite. The Hodges, well first the authorities came in and scooped it up. This was of course the height of cold war terror, and so they wanted to check it out, make sure it was truly just a random rock from space.

S: Not something from the Ruskies, right?

R: Right. Hodges and her husband asked to have it back but also their landlord, a woman named Birdie Guy also said that she deserved it because it was her land which technically apparently legally at the time she was in the right. It landed on her land and the meteorite belonged to her. She went to court over it, she ended up settling, I think she got like $500 in exchange for the Hodges being able to keep the meteorite. They then tried to sell it but by the time they got hold of it apparently interest had died down quite a bit, they couldn't get rid of it, and eventually Mrs Hodges, over the objections of her husband, apparently ended up donating it to the Alabama Museum of natural history which I think still has it today.

S: Yes, they still have it.

E: And it's worth $54 million dollars... No.

R: There are other cases where people claim to have been hit by meteorites but this is the best documented example. The next-best example was one from 1992, a meteorite, like a small bit of a meteorite apparently hit a young Ugandan boy but I couldn't really find much documentation on that.

S: Well I found that, I found a published report.

R: Did you? Because I found a report on the meteorite but I didn't see anything about it hitting the boy.

S: The report, because the meteorite broke up into a lot of different pieces, they gathered as many of those pieces as they could, I guess to study how it broke up and what the pieces looked like and everything, and in the report it mentions the Ugandan boy who claimed to have been hit on the head by a small piece and they actually even, there's a picture of him holding the fragment and they give the size of the fragment.

J: So what happens to you? How fast is it going like did it knock him out? Knock his teeth out?

S: Well it only weighed 3.6 grams, the piece that hit him. Apparently it was slowed significantly by the leaves of a banana plant. See!? You all mocked me for having all those banana plants at my house, but...

R: Is that what you're doing? You're just protecting yourself from meteorites?

S: A meteorite shield, that's right.

E: A meteorite umbrella.

(laughter)

E: Who's laughing now?

R: You know when the cops raid your house thinking that you have some sort of pot operation going, please don't tell them that they're just banana plants to protect you from the meteorites.

S: (laughs) that's right.

R: The Hodges meteorite, which is also known as the Silikowga Meteorite because that's the name of the place in Alabama where it landed, it was the size of a grapefruit apparently but you should see the bruise it left on this poor woman, it was ugly.

J: Rebecca, if I was standing next to you and I threw a grapefruit at you I would do more than bruise you, I mean this is a rock! It didn't knock her face off? Nothing crazy happened?

R: Well it hit her in the leg, in the hip.

E: It bounced off a radio first, so that's...

R: Yeah and it had bounced off a radio and made a giant bruise.

J: No banana trees or anything to help?

S: No banana plants!

News Items

MAVEN Launch (8:30)

• http://theness.com/neurologicablog/index.php/maven/

S: Alright well for this next news item we're going to be joined by Eliot Goldman, Eliot welcome to the Skeptics' Guide.

EG: Hey thanks rogues, it's great to be here.

S: So Eliot, you're on because you work for Lockheed Martin, and you were involved in the MAVEN satellite which was just launched to Mars.

J: MAVEN!

S: And... yeah.

R: Good try, Jay.

S: You kindly invited us donw to see the launch and I was able to make it down there with my family so we met you down there, we had a great time.

EG: Fantastic time. Thanks for coming down, I really enjoyed your visit.

S: So yeah we're going to talk about the MAVEN launch really quickly. So let me give a little bit of background and then you can tell us what your part of the satellite was. So MAVEN stands for the Mars Atmosphere and Volatile Evolution probe and this was just launched on November 18th, everything went well, and it's on its way to Mars. It'll get there in about 10 months and it will go into a very eccentric orbit around Mars so it can sample the different levels of the atmosphere. So the primary purpose of this probe is to find out why Mars lost its dense atmosphere. We know that Mars must have had a denser atmosphere billions of years ago because there was liquid water on the surface of Mars and you need a certain amount of air pressure for that to happen. But the solar wind has since blown most of it away but the purpose of the probe is to find out exactly, or more information about what happened to Mars' atmosphere. Apparently it's also going to be a relay, a sort of communication satellite for the rovers that are still on the surface of mars as well. But you were involved in, Lockheed Martin didn't make any of the scientific instruments if I understand correctly, but they made the probe itself. So what was your part in making the probe?

EG: Yeah that's right, we built the boss, the structure, and the computers, the avionics that fly it and we also operate it, but we don't build the payloads, the payloads are built elsewhere. My specific job was designing the solar array substrates, I worked on some RF components called waveguides, I worked on the mechanisms that deploy the solar arrays and designed a bracket for the star trackers which are these fancy Italian star cameras that are super-expensive and they're mounted and look at space and give us kind of precise knowledge of position.

S: Right. I remember, right after the launch everyone was celebrating but you had to hold your breath until the solar panels opened up because that was your bit, if that didn't work then there would have been a problem for you.

EG: Yeah.

R: Would you have been fired if that didn't work?

EG: Probably not, there's someone above me I think I could pass the blame to.

R: There you go.

EG: I'd probably be under a little bit of scrutiny if we had a failure. I worked on the, what's called the R&R, the restraint and release devices for the arrays and I redesigned something we had built in the past and so the design was a little bit novel thanks to me so if there was a failure I would probably be called in to speak about it. But yeah it was an exciting thing to work on.

S: Yeah. The launch day was really exciting I mean beyond just watching a huge rocket take off like that. So the weather was a little bit dodgy, they were giving a 60% chance that the rocket was going to launch. So we didn't know until 4 minutes before the rocket took of whether or not it was actually going to happen.

J: What time did it launch, Steve?

S: It was 1:38 in the afternoon local time. Or 1:28. One of those. And it was really exciting so while you're sitting on the benches, we're just across the bay from several of the launch areas, the launch pads including the ones with the MAVEN on it. We're sitting there and they're talking the whole time, there's speakers set up so we're hearing people over the speakers. Sometimes they were talking to us, sometimes we're just hearing the NASA chatter happening. At one point they do the go, no go where there are like 30 people who all have to give a go from their station. We're hearing them read off each bit and everyone either saying go or no go and they go all the way down to the guy who is in charge of the whole thing, who gives the final go, so of course when he said that the mission was a go and they restart the clock, becaue they stop the clock at 4 minutes for 10 minutes to get caught up on everything, and they restarted the clock at 4 minutes. That was really the first moment where we knew 100% that it was going to launch and it was so exciting, it was incredible.

E: They do that for dramatic effect.

EG: Happens every time.

J: Hey so what's it like being on the other side of that? Are you in the station where they're controlling everything and what's it like/

EG: No I was down there on vacation with my family. My work is done primarily once we've built the structure and delivered it to our assembly team, we call them PATLO (sp?), assembly and test operations. And once the spacecraft has been assembled, my work is done and I'm on to the next spacecraft. So I was just down with Steve taking personal time. But I heard some of my colleagues that were on-console at that time.

R: So what's the next spacecraft?

EG: I'm working on OSIRIS-REx right now which is an asteroid sample return mission.

E: Cool.

R: That's a great name, a mighty name.

E: Yeah.

S: OSIRIS-REx.

EG: I don't know, don't quiz me on the acronyms because I won't be able to tell you what they are. I told you Steve, I said you probably don't want to interview me, you probably want to interview a systems engineer someone who knows the whole spacecraft pretty intimately. I have a really narrow focus. I'm a mechanical engineer and I do design for structures and mechanisms, deployables, things like that.

S: You're like Howard Wallowitz.

R: Who's Howard Wallowitz?

S: Big Bang Theory, come on.
