#NewHorizons #PlutoFlyby – The Pseudoscience Flows #8: Where Are the High-Res Pictures?


This will be another short post, but it’ll hopefully tide you over while I’m home for 3.5 days before headed back to Maryland for a New Horizons Science Team Meeting. First off, you should read my Part 6 post about how the data are being downloaded from the New Horizons probe to Earth.

With that said, Richard Hoagland has moved up in the world and has his own radio program on Art Bell’s network. Richard gets 10 hours per week (2 hrs per week night). I finally figured out my recording software and so was listening today to his Friday night / Saturday morning broadcast where he had on his significant other (Robin Falkov) and amateur image processor and image anomaly = intelligent artifact finder Keith Laney. But that’s somewhat beside the point, for this is the pseudoscience for this post:

  1. Richard Hoagland thinks that if he were managing the mission and the the probe might die tomorrow, he would send back the best pixel scale images first.
  2. Therefore, we must have done that.
  3. But, they are not being released.
  4. Therefore, “NASA” is hiding these 70-80 meter per pixel images because “NASA” is trying to figure out what all the buildings mean.

Spot anything wrong with that line of reasoning? How about steps 1 and 2, the basic premise.

Richard Hoagland is wrong.

From a fundamental standpoint, besides everything I wrote in that part 6 blog post. If you’re in charge of the mission, and you fear there is a small possibility that your probe might die, you would want to bring down the most representative data, and the data that will tell you the most about different things across the body rather than a tiny less-than-one-percent-of-the-surface-area image that would itself take many hours to downlink without lossy compression.

And – ¡gasp! – that’s what we did! We brought down images that give us the broadest possible view, and we brought down data from the other instruments that do the same. Remember: New Horizons doesn’t just have a black-and-white camera. It has seven other science instruments!

Besides that, more organizationally and methodically, there are literally hundreds of individual science questions/goals that we had for New Horizons’ data to answer. Every single observation made was linked to one or more of those goals. And, those goals were prioritized not only into four main tiers*, but within each tier they were prioritized, as well. Each was audited multiple times by many different mission scientists and very carefully worded and planned. And — guess what! — 70-80 m/px images of a tiny area of Pluto are not in the Tier 1 goals. So, when you want to prioritize your data downlink during that crucial few-days period after the closest approach, you’re going to bring down the data to answer the most Tier 1 goals/questions.

So … yeah. Richard is wrong in his conspiracy because his assumptions are wrong which he assumes are correct. Put another way: Richard thinks something, which (to him) makes it fact, and then he makes conclusions of conspiracy based on that “fact.” But his basic thinks is wrong, therefore everything else that came after that thinks is wrong.

*This is why after the “anomaly” during the July 4 weekend, the announcement was made that “No Tier 1 goals will be affected.” That’s because the data that would have been taken during those few days were not crucial to any of those goals/questions. One observation, for example, was a “family portrait” that would be the last time New Horizons could fit the entire system in a LORRI field of view. That was more for public outreach, so it was a 3.9.x goal, but it also would have helped determine orbits of outer satellites which means it doubled as a tier 2 goal.

#NewHorizons #PlutoFlyby – The Pseudoscience Flows #6: Data Download


Introduction

I know I’ve promised other parts to this series, but this one will be quick* and I want to get it out there because it feeds into a lot of varied and various conspiracies related to NASA’s New Horizons mission to the Pluto-Charon system, and I’ve even seen many misconceptions on normal science blogs / websites (not to be named): Where’s the data!?

Deep breath people: It’s coming. Slowly.

*I thought it would be quick, but it turned out to be nearly 2000 words. Oops…

The Slowness of Spacecraft Data Transfer

Every space mission – save for one very recent, experimental one – relays data via radio signal. In other words, light. The amount of power that the spacecraft can muster goes into figuring out the data rate it can sustain. Think of it a bit like this: If you have the Bat Signal, but you were using a flashlight, you’d be lucky if someone could just see the flashlight aimed up at the sky. There’s no way they could see details of a bat cut-out. But if you use a really really bright spotlight, you can see it farther, and you can even stick a detailed bat cutout over its front and you can make out that cutout.

Perhaps a bad analogy, but that’s kinda the idea here: If you have a very strong signal, then you can include a lot of detail really quickly. If you have a weak signal, then the data rate is slower. Oh– better analogy: bad wifi reception. You know you have low signal strength when it gets really slow.

Moving on, the New Horizons REX antenna does not have a huge amount of power. New Horizons launched with less plutonium for power than originally intended, and it needs power for running the spacecraft. It has so little power for the antenna that only the 70 meter dishes in NASA’s Deep Space Network (DSN) are big enough to receive the signal at Earth, which is a paltry 3 * 10-19 Watts. (Compare that with a 100 W light bulb.) To me, first off, it’s amazing that we can even receive that faint of a signal.

But once you get over that amazement, the DSN also has to be able to detect changes in that tiny signal. That’s how we get data. Like blinking your flashlight in Morse code, or putting the Bat Signal stencil up. If we have very little signal strength, we can’t change our signal very quickly, or the DSN may not be able to read it. Change more slowly, then they will.

For planning purposes, we were able to send data at 1296 bits per second. I’m old enough (sigh…) to remember dial-up modems in the 1990s. My family’s first modem was the dreaded 14.4 kbps modem which was painfully slow at pulling up AOL’s e-mail. Or Hamster Dance. But even that was over 10 times faster than New Horizons’ data rate. And, let’s convert it to real things, bytes. There are 8 bits to a byte. 1296 bits per second is only 162 bytes per second. I have a thumbdrive attached to my computer that holds 64 GB, or 64 gigabytes. It would take about 4572 hours, at the average New Horizons download rate, to fill that fairly modest thumb drive. That’s 190 days.

Keep in mind that the spacecraft is still taking data. Keep in mind that there are only 3 70m DSN dishes at the correct latitudes to see the spacecraft, ever, from Earth. Keep in mind that there are other missions out there that need the DSN to communicate with Earth. Keep in mind that 1296 is an average planning bit rate, and while the Canberra and Goldstone dishes get more like 2000 bps, Madrid tends to get less due to the elevation of the spacecraft above the horizon.

So, from the get-go, just from considering the data rate (power requirements on the spacecraft, distance to the spacecraft, and timetable of receiving stations on Earth), one should be able to see that it will take a painfully long time to get the data from the spacecraft.

While we could keep up with the data rate and did a large download a month before encounter (which is why data weren’t taken in late May), there’s no way we could get all the data during encounter very soon after it, which is why the craft flew with two 8 GB storage drives, and it filled up 60 Gb during encounter (see what I did there, switching between bit and byte?).

There’s Other Data Besides Images!

And that’s any kind of data. There aren’t just images and “pretty pictures” that many of us want. There is one B&W camera on the craft, but there’s also a color camera, two spectrometers, a dust counter, two plasma instruments, the antenna itself took data, and there’s basic spacecraft housekeeping and telemetry that says things like, “Yes, I really did fire my thrusters at this time when you wanted me to!”

Basic Download Plan

I can discuss this because the basics have been made public. It’s just not “sexy” like pretty pictures so it’s not that easily findable.

Leading up to encounter, data were prioritized as though we were going to lose the spacecraft at any time, so the most important, “Tier 1″ science data were downloaded first. And, critical optical navigation images.

After encounter, the same thing happened, where compression algorithms were used on the data on-board the spacecraft and that lossy-compressed data were sent back to Earth to fulfill as many Tier 1 science goals as possible. That’s how – and why – in the last week we’ve already revolutionized what we know about Pluto. Those first high-res (0.4 km/px) images of the surface were planned out based on Hubble Space Telescope maps of the surface and the spacecraft timing and trajectory to get images that cover different brightness and color patches. (Which takes care of another, minor conspiracy that I’ve seen that claims we “knew” where to point the cameras because the Secret Space Program had leaked us information about what would be interesting.)

But now that we’re more than a week from closest approach, thoughts are turning to what to do next. Originally, a “browse” data set of all the lossy data (only the imagers and spectrometers store lossy-compressed in addition to lossless) were going to be returned first, along with the lossless data from other instruments. That would at least let us at least understand the surface at a lossy JPG quality and for the plasma folks to do their science.

But now people are discussing scrapping that and bringing down the lossless data instead, albeit many times slower because of the larger file sizes.

Planning, Fairness

But, believe it or not, planning of what’s downloaded when is made no more than a few weeks out (except for the closest approach weeks). Right now, we’re working on the late August / September load of commands and deciding what data to bring down in what order.

Each of the four science theme teams (geology geophysics & imaging (GGI), atmospheres, composition (COMP), and particles & plasma (P&P)) puts together a list of their top priorities based on what we’ve seen so far. The Pluto Encounter Planning (PEP) team then sits down and looks at how much they can bring down in what time and puts things in order. The sequencers then take that and try to make it happen in the test computers. Then we iterate. Then it gets reviewed. Extensively. Only then does it get uploaded to the spacecraft to execute.

But besides that priority list, it’s the Principle Investigator who decides how much data each science team gets. For example, while I’m on PEP (it’s what I was initially hired to do), I’ve been adopted by GGI. Wearing my GGI hat, I want images from the LORRI instrument. All the time, and only LORRI. I don’t care what the plasma instrument PEPSSI recorded. But by the same token, the P&P folks don’t care anything about images, they want to know what their instruments recorded as the craft passed through the Pluto system to see how the solar wind interacted with escaping particles from Pluto – or even if it did. (Which it did, as was released in a press conference last Friday.)

So Alan Stern has to make the decision of how to be “fair” to so many competing interests within the large – and broad – science team. So while COMP may want to have 5 DSN playback tracks in a row to bring back just one of their very large spectra data cubes, Alan has to make sure that GGI gets their images and P&P gets their data, too.

The Plan

The decision was made several months ago that after this initial batch of data – what we saw last week, what we see this week – that all of the “low speed” data will come down in August. That’s housekeeping & telemetry, that’s things like how many dark pixels are in any given LORRI image, it’s the two plasma instruments and data recorded by the antenna and dust counter, and that’s about it. After that, we get back to the imagers and spectrometers, per the balance discussed above.

And since it’s not sequenced, and it’s not public, I can’t tell you any more than that.

So we are, unfortunately, not going to see any new images for practically a month, beyond the two navigation images that should come down tomorrow and Friday.

Conspiracy!

Due to the nature of this blog, obviously this is going to fuel conspiracies: NASA’s hiding the data, NASA’s manipulating the data, NASA’s [whatevering] the data, etc.

It’s just not true.

I have known for years that these conspiracies about NASA somehow intercepting the data and manipulating it before even us naïve scientists can get our hands on it would be very difficult, but being on this mission has made me realize that it’s even more difficult to somehow support that conspiracy than I had thought.

Literally, as the data are received by the DSN – before it’s even completely downloaded – it’s on our processing servers and in the processing high-cadence pipeline. On Monday morning when we were supposed to get four new images, we were literally sitting in the GGI room hitting the refresh button and marveling over each new line of pixels that we were getting back in practically real-time. To use a religious analogy, it was every Christmas morning rolled into a one-hour marathon of hitting the refresh button.

And we were all there watching — over 20 of us. And other science team members kept coming in to look.

The idea of secretly having one or two people intercepting the data, “airbrushing” things in or out of it, and only then giving it from On High to the scientists just shows how out of touch from reality conspiracists are.

To sustain the conspiracy, I can only see one of two choices: (1) Either all of us scientists are in on it, in which case it becomes ridiculously large and unsustainable and scientists suck at keeping secrets about exciting new things, or (2) somehow there’s super secret advanced tech that intercepts the spacecraft signal and at the speed of light “airbrushes” things out and retransmits it to the DSN to get into our processing pipeline. Because we know when stuff is supposed to appear on Earth. Because we write the sequence that does it.

Final Thoughts

Not that I expect this to convince any conspiracy theorist of their folly. The lack of image data for the next month, and the lossy JPG data we have now all contribute to the little anomalies that don’t immediately make sense, and the average conspiracist can easily spin into something that it’s not.

#NewHorizons #PlutoFlyby — The Pseudoscience Flows, Part 4


An eagle-eyed Facebooker on the Facebook page for my podcast (thanks Warwick!) pointed this ‘un out to me on the Before It’s News website. Something like the equivalent of the Daily Mail but with more of a UFO bent.

Apparently there are huge cities on Pluto.

This was one of the pseudosciences that I knew going in was going to be prevalent, though I expected it to be more explicit first from Richard Hoagland and Mike Bara who are more vocal about their pareidolia and reading into image artifacts.

The entire crux of this guy’s arguments is that he sees a blockiness in the released images. He claims that he knows and can prove they are not JPEG artifacts for two reasons:

(1) He’s using a TIFF image and not JPEG, and
(2) the blockiness runs at a diagonal and not parallel to the image edges.

For the second reason, I have two words and two punctuation symbols for you: “Rotate & crop.” To add a a few more words: Most released full-disk images have been rotated such that the north pole is “up” in the image. The spacecraft didn’t take them that way. We rotated them to be consistent. Therefore, the original blocky compression artifacts run parallel to the image edges, but now they run diagonal because it’s been rotated! Pretty simple. Yet it has eluded this conspiracist.

Similar elusion is of a simple fact that all because your current file format is one type, that does not mean the original file format was that type. To be more explicit, all because the NASA press release you got this image from happens to be a TIFF on the NASA website, that does not mean that the original image downlinked from the spacecraft was not lossy-compressed JPEG. Which it was. No image downlinked from the craft since July 12 has been lossless, they have all been lossy. Via a 10:1 ratio, meaning they are very lossy. All because I can take a JPEG and use any image software to re-save it as a TIFF does not mean that TIFF will not contain those original JPEG artifacts.

The JPEG blocks are 8 pixels on a side, and many of the released images have been up-sized (I don’t know why, I argued against that, but I have no influence over NASA’s nor APL’s graphics people).

He also assigns the wrong image credit, as “NASA/JPL-Caltech/MSSS.” It’s “NASA/APL/SwRI.” That’s not hard to get right. It’s called reading the caption for the image that you take from NASA.

I’d say that this is one of the sillier conspiracies I’ve heard so far, but it’s really hard to choose. Especially with what’ll be parts 5 and 6.

Perhaps the best line from the video: “No one’s actually accused me of, uh, pixelation, yet, but I’m sure someone will. Uh, some— some spook, probably, some guy from MI6 will come on here … heh! Who knows? Or someone from NASA will try and debunk it. But we’ll see! We’ll see what they have to say.”

Ah…. if only I worked for NASA, or MI6. Maybe I’d drive a nicer car. But it doesn’t take someone from British Intelligence to tell the guy that IT’S JUST BEEN ROTATED!!!

P.S.: Also within the video are other various claims. Like a large hexagonal crater (no, that’s his mind trying to break a circle into line segments), and that NASA purposely brightened the image so that it washes out detail near the pole. No, that’s called the sub-solar point, which is where the sun is directly shining, so you can’t see any topography, only brightness differences of the actual material on the surface. It washes everything out.

#NewHorizons #PlutoFlyby — The Pseudoscience Flows, Part 3


Introduction

I honestly haven’t seen this one that I remember — yet (I’m working on very little sleep and 14+ hour days right now) — but I suspect it’s only a matter of time from more conservative religious conspiracists: The naming scheme for Pluto and Charon. Some background is needed …

Names

In planetary science, one might wonder why we care about naming things. It seems to be a remarkably human-centric thing, for why should we have to feel like we need to stick a name on everything?

The answer is ease of communication. If you say “Tycho crater” to just about any planetary scientist, they know the exact lunar crater you’re talking about. Same with “Copernicus crater,” or “Mare Imbrium.” The alternative is something like, “The big crater with bright rays near the bottom of the moon if the north is up.” Or something like that.

Other than historic objects, things these days on planetary surfaces generally only get named if there’s a reason for it: As in, it’s an interesting feature that we’re going to be talking about a lot. Not every feature on every body is named.

International Astronomical Union (IAU) Policy for Pluto System

Because Pluto is the Roman god of the underworld, and Charon is the Greek ferryman of the dead to the underworld, the International Astronomical Union — the only official naming body in the world for naming stuff in the solar system and beyond — decided that the theme of “underworld” is going to stick, at least for major features. Sometimes this varies, but more on that later.

There is a sizable component of conservative Christians who think that any naming, or any reference, to such is an affront to their god, that it is occultism, Satan worship, etc.

Another side-rule is that no name should be duplicated.

Process

There are lots of “levels” of names. There’s the official IAU name. There are provisional, recommended names to the IAU. There are “for fun” names used within the science team. And there are “would be nice” names used by individual people.

As an example of the last item, there are many craters right now on Pluto and Charon named “Robbins” with a lot of numbers after it. For a friend, there are two “Banks” craters (one because I’m not sure if it’s real because of JPG compression artifacts). But that’s just for fun.

The more formal process, those other three levels I mentioned at the beginning of this section, varies somewhat. In the case with New Horizons and the Pluto-Charon system, a public website was launched months ago where people could both recommend and vote on names.

This was vetted by a very small group within the New Horizons science team, raking names by popularity, looking for gender and ethic biases, removing incredibly offensive names, and removing those used elsewhere (e.g., there’s a “Lonely Mountain” on Titan, so even though we’ve been referring to one on Pluto lately in the team, it cannot be recommended as an official name to the IAU, but this falls into the third category of “for fun” by the team).

So, the biggest stuff is going to get the most popular names from the list. And by “get,” I’m talking about that that second level, the recommended-to-the-IAU level. Which I think pre-approved “Tombaugh Reggio” before-hand. But beyond that, all names must be submitted to the IAU, and hence they are called “provisional names” until the IAU approves or rejects them.

The “Offending” Name(s)

Right off the bat, I figure that there will be some groups that are offended already by the “underworld” theme. But I read some very über-right-wing Christian / conservative websites. One of the beliefs among them is that anything “new age,” anything they perceive as pagan or “occult,” is Satanic, and therefore directly opposed to their version of a deity.

Enter Cthulhu (pronounced something like “coo-THOO-loo”). It was a deity created by H.P. Lovecraft. To quote from Wikipedia: “Lovecraft depicts Cthulhu as a gigantic entity worshiped by cultists. Cthulhu’s anatomy is described as part octopus, part man, and part dragon.”

Lovecraft himself is often viewed by these über-conservative Christians as an occultist/cultist himself, and the fact that a major low-reflectivity feature on Pluto that has been provisionally named after a “demonic” deity that Lovecraft dreamed up is likely going to not sit well with them.

However, my understanding is that it was selected because it was one of the most popular names in the voting.

Final Thoughts

Well, that’s it for now. Back to work. I expect to do at least two more of these, another about young-Earth creationists’ take on this and another about Crrow777’s take on this (he’s been getting a lot more press lately, so even though I really don’t want to give him more because question his mental fidelity).

#NewHorizons – The Pseudoscience Flows, Part 2


“Of course, I have no proof of this …”

Thus just said Keith Laney on Richard C. Hoagland’s internet radio program on Art Bell’s Dark Matter radio network. He was shocked an hour ago at the incredible details being revealed in the publicly released images this morning. Then, about 10 minutes ago, we had a NASA guy come into our geology room and tell us that we were so popular that we crashed NASA’s website. I knew that it was a matter of moments before the conspiracy folks would spin something.

And so, they did: NASA was releasing such good stuff and such “revealing” images of Pluto (despite them being lossy JPGs of lossy JPGs — the lossless version of this image will be downloaded probably the first week of August), that their website was shut down by Those In Control.

Sigh.

Also, two misconceptions: Richard spent quite a bit of time complaining and being mystified that there was no live radio signal from the craft. New Horizons has one moving part, the door to the Alice instrument. That’s it. Other craft usually have a science platform that can be rotated. New Horizons doesn’t. So we can either take data of Pluto and its system, or talk to Earth. Guess which we’re going to do when we’re closest?

It was another moment of arrogance, actually, on Richard’s part. He was astounded that no news media were asking this question during the NASA press conference. He remarked that the reason that HE thought of the question as opposed to the news media was that he has a lot more experience in this sort of thing. No … it’s because they know how to read Wikipedia.

The other misconception is not just Richard’s but is being played across many different media: The signal tonight is a “phone home” of the spacecraft health. Data won’t be until many, many hours later.

#NewHorizons – The Pseudoscience Flows


Introduction

Sigh. We knew this would happen. But I’m always intrigued as to what form it will really take. I’ve been monitoring some sites, some people, and here’s some that I’ve found so far. Two mainly.

Pluto was ejected from Earth during the Great Flood

Ol’ Terry Hurlbut, one of the premier editors/contributors to Conservapedia, is a young-Earth creationist. He has an Examiner.com site and his own ConservativeNewsAndViews.com site which duplicates said Examiner content and has contributions from other, like-minded über-right-wingers and young-Earth creationists. His contribution is fairly straight-forward: Pluto formed recently – but not as recently as Earth – during Noah’s Flood. Why?

Well: Pluto is red. Rusty red. Therefore it has rust. Therefore it must have iron that was in an oxygen-rich environment. Therefore it came from Earth. QED

Richard Hoagland

Richard is a moving target these days. There’s a lot of drama – the basics of which have to do with the feud between Art Bell and the program he founded but its current incarnation, Coast to Coast AM. Steve Warner, host of the “Dark City” internet radio program (also on Art Bell’s network), got a two-hour interview with Richard late last week and it went up just two days ago.

Richard himself will have (or depending on when you read this, has had) a 6 5 hour special from 3-9 2-7AM PDT on Tuesday morning, July 14, the morning of the flyby. He offered a preview on the “Dark City” interview, and I jotted down a few notes:

1. The Pluto system is young or artificial: Because no rings or tiny moons have yet been found, as was predicted (and therefore “MUST” be found IF the system is natural), then the bodies are either made of material that does not produce rings or tiny moons (ergo artificial) OR it’s incredibly young (ergo artificial).

2. Richard thinks it was created by a Type II civilization (can harness the energy of a solar system) that died 65 million years ago and so isn’t enough time to accumulate rings / tiny moons. It has archives/libraries where our “true” history is stored, and it didn’t suffer from the exploding planet that created the asteroid belt at that time which is also why neither Pluto nor Charon should have many craters.

3. He expects the “regular, geometric patterns” that are evidence of this civilization to be prominent. He also thinks the cantaloupe terrain on Triton is buildings buried by methane ice that NASA released but just never mentioned, and he expects to see more of it on Pluto.

4. “We’ve already found some staggering, repeating, right-angle geometry that has no business being there, and yet no one has commented about it because they don’t know what to say!”

5. The “weird computer outage” was a warning to NASA to not show what’s really there … from “somebody.” Either Alan Stern (the mission PI) will go along with it, or he’ll show what’s really there. Because of the IAU controversy, Richard is betting on Alan’s integrity to show “us” what’s really there. (Note: Richard says this about every PI or non-US country for every space mission. If Richard can pull the noise out of the images the way he wants to find “regular geometry,” Alan has integrity and Richard wins. If Richard can’t pull it out, Alan was threatened and Richard wins.)

6. The IAU vote was done to increase public engagement (through controversy / soap opera) of Pluto so that Alan can do the big reveal that it has alien archives on it in a few days.

To Be Continued?

I’m incredibly busy these days, so I’m not sure if I’ll have time to post more of these. But, I wanted to let you know what I’ve found so far that’s the most “coherent.”

Podcast Episode 133: Element 115 and the Credibility of Bob Lazar’s Claims


Ununpentium’s
Existence: Does it save Bob
Lazar’s U’FO claims?

A return to the roots of the podcast: A simple exploration of a claim, and what was found. Sort of. The first third of the episode is a look into the story of Bob Lazar, a man who is often credited (in part) with re-invigorating the UFO community in the late 1980s / early 1990s. It’s important for context, because embedded within that story is a general lack of credibility for his claims.

Enter element 115, which when it was discovered in 2003, became a rallying point for Bob Lazar’s supporters: The very existence of something that had not yet been discovered when Bob Lazar made the claim, means that his claims must be true. We see this a lot of times in the UFO field, but I really focused in this episode on this specific claim and the specific set of claims about element 115 made by Bob Lazar, before its “mainstream” discovery.

This episode does get a little technical because I talk about some basic particle physics, but I think it’s on par with most of my other episodes in terms of technical jargon and concepts.

And, that’s about it. There’s a short logical fallacy segment, where I ask your help in identifying the main logical fallacy for the episode, which I’ll then discuss next time.

It’s also important to note that the podcast is on Stitcher, and I should’ve checked my stats before I mentioned them at the end of the episode: I’m now on 33 peoples’ playlists and I’m ranked in the 3000s, not on 22 peoples’ playlists and ranked in the 5000s. Not bad for only being entered in late March and not doing much to promote it.

Podcast Episode 132 – In Search Of Planet X (Live from Denver ComicCon)


In Search: Planet X.
An overview of common
Ideas about it.

This episode is another recording of one of my live presentations, modeled a little after Leonard Nimoy’s “In Search Of” television series. It was presented in front of a live audience at the Denver ComicCon on May 24, 2015, to about 75-100 people. I was bordered on two sides by other sessions that had more people and a lot of laughter, so I played to that a little bit when there were opportune moments. I also suffered a minor A/V issue in the middle but recovered, so you’ll hear some fumbling there.

Unfortunately, there is also some popping that comes in about 10 minutes into the recording. I exploited all the filters that I know of in my Audacity toolkit, and they are less of an issue than they were, but they are definitely present.

I also need to announce that it is that time of year when work is going to get crazy, so episodes may come out a little less regularly, especially during July. I’m still going to keep to the two per month schedule, but they may not be out on exactly the first and sixteenth of the month.

And with that in mind, I have to head to the airport in 45 minutes for more work, after just being back home for 3.5 days. So …

Podcast Episode 131 – Clip Show #3: Blood Moons, Ceres’ Bright Spots, MESSENGER’s Death, and Funding in Science Follow-Up


Blood moons, science cash,
And spacecraft conspiracies
Are topics du jour.

Clip Show #3 is a big catch-up on several miscellaneous topics: The latest lunar eclipse, Ceres’ mysterious bright spots, MESSENGER’s death plunge into Mercury, and a large follow-up to episode 126 which was my interview with Dr. Pamela Gay about funding in science. This episode also had a logical fallacy section – cherry picking and anomaly hunting – and a feedback/Q&A about whether NASA has created a Warp Drive, and finally my long-foreshadowed tribute to Leonard Nimoy, with how he or his characters influenced myself and you in some way.

There’s really not too much else to say about this episode. The next one will likely by about Big Bang Denial (along similar lines to episode 125 about Black Hole Denial and a future one about Dark Matter Denial). And, this Friday/Saturday, I should be back on “The Reality Check” podcast discussing exoplanets and that we’ve been on the cusp of detecting an Earth-like planet … for many years.

Of science: Who can get in,
And who remains out?

Second in the three-part series: Have you ever wondered how decisions are made about who can and who cannot present at a scientific conference? Then listen to this episode! I interviewed Dr. Dave Draper, who chairs the program selection committee for the largest annual planetary science conference in the world. We talked about a lot of things, from the basics on the (incredibly minimal) requirements of submitting a presentation request to how decisions are made. We also discussed a few hypotheticals using real-world examples of pseudoscience that I’ve talked about on the blog and podcast.

The episode, like most of my interviews have been, is nearly an hour long, but I found it an interesting discussion and learned some things, so hopefully you will, too. There were not other segments in this episode, though I did do a follow-up because of what happened to air on Coast to Coast that evening, a mere 12 hours after Dave and I had finished recording, and it led me to disagree with him at least a bit on one point.

The next episode is going to be a bit of a catch-up on things that have been piling up since I started the Hale-Bopp saga back in March. I’ll do a bit of pseudoscience with whether or not the lunar eclipse we had in April was really a full one – and implications for the “Blood Moon” crapola – a lot of feedback including discussion about some points raised by Pamela Gay in episode 130, and the Leonard Nimoy tribute.
