The Map is the Tale (WW103)


Our third episode airs this Monday evening on AFM and features an interview with Phillip Stooke who sat down with producer and co-host Alyssa Gilbert. Stooke is one of several members of the Centre for Planetary Science and Exploration who is distinguished by having a namesake in orbit around the sun, asteroid 172996 Stooke. Stooke, a professor in the geography department at Western is known largely for his cartography. In particular, he enjoys combining his map making with a historical perspective, hence his 2007 map of lunar exploration and an upcoming map of Mars exploration, tentatively titled "From Spirit to Curiosity" with an anticipated release date of 2015. I'm very hopeful we can make his title a reality this summer with a successful landing of MSL!

It may surprise you to learn that Phil was the first professor at Western whom I met when I first showed up in December of 2010. When my supervisor was delayed by a meeting, I decided to go over to a lunch-time gathering to discuss images from other planets. I brought a couple of photos taken by Cassini of Iapetus with me that fooled a number of the other students there. They really do look a lot like a frosted Mars. But very little gets by Phil and he correctly identified the moon with his first guess.

Later, he was the subject of a very interesting PSERF where he discussed ancient mapmaking on the Earth. Many of the so-called T-and-O maps showed landmasses that didn't actually exist. The reason for this? An ancient greek belief that the moon was a mirror that reflected the geography of the Earth. Hence my title and quote for this week in which I emphasize the storytelling role of mapmaking. If ever you need proof, just walk down the street and think about what those names on the street signs represent.

As always, Phil tells a fascinating story and his interview is no different. I'll leave you with that and my  recollection above to whet your appetite. As always, my introduction can be found beneath the cut.

Our Coy Mistress (WW102)


Tonight's guest on Western Worlds is Paul Delaney. This time around, I had the pleasure of speaking with Paul in person. He and I go back a fair ways to the summer of 2009 when I was working at Environment Canada. At the time I didn't know if I would ever work in Planetary Science or Astronomy again, and I was beginning to lose my connection to the field in which I was trained. So, I decided to see if there was some way in which I could use my PhD to engage with the public and rekindle my own passion for planetary. 

I emailed around to various departments, planetaria and observatories to see if there was some way I could be of use. As you might expect, most chose not to reply while others told me that they were doing well and needed no help. But Paul got back to me, invited me out to the observatory and the rest is history. Today I have a very fruitful collaboration with the York University Observatory that is almost three years old.

It was also Paul that gave me my introduction to the world of AFM. I started out as a guest on "Live from York U" (the precursor to "York Universe"). When that went well, I was asked to become a regular co-host on the program. But with the move to Western, it was time for me to strike out on my own. Again, I had the full support of Paul and he midwifed the pitch that Alyssa and I made to AFM that was ultimately accepted as "Western Worlds."

The title above for this particular episode is fitting for several reasons. As a dear friend of the show, we mean to evoke Paul's quiet contribution. But the title is also meant to pay homage to my WEaT speaking tour on which Paul got me started last year. That was an especially successful endeavor in which I learned that I could really enjoy sharing my enthusiasm and expertise with the public. The closing words of each show will continue this tradition.

So won't you join us tonight? I'll be there at 10 PM ET, 3 AM UTC on Astronomy.fm along with a friend who helped to make it all possible. You can find the text of my intro is behind the cut.

Western Worlds off to a great start!

This past monday, we had our big debut and I need to thank you all for listening in. Our producer over at AFM crunched the numbers today and estimates that our first episode had a listenership of nearly 20,000 people! That astounds me - I can barely believe it! So thanks for listening in. And thanks again to York Universe for their great lead-in! I, and the rest of the WW team, will do our best to continue to provide you with an engaging look into planetary science and exploration along with the people who practise it.

If you missed our first episode, you can download a podcast of WW101.

Wondering what the first one was all about? Well wonder no more! My introduction can be found beneath the cut. Don't miss us next week on Monday when we'll have Paul Delaney on the show.

Introducing: Western Worlds

The short-form logo for the newest AFM*Original program, "Western Worlds."

For those of you who enjoy York Universe (you can check out our new website here) I am happy to tell you that there is a spin-off show on the way and it starts at 10 PM ET on Monday, February 27th! The name of the show is "Western Worlds." Here's the format: the show is thirty minutes long and each will feature an interview with an engineer, researcher or educator working in the planetary sciences as interviewed by one of our capable co-hosts. That's the first twenty minutes. The last ten minutes will feature a round table with several co-hosts as we draw upon our own individual expertise to understand what the interview subject's work means to each of us.

The show is being co-produced by Alyssa Gilbert of the Centre for Planetary Science and Exploration (CPSX) at the University of Western Ontario and by Michael Foerster at Astronomy.fm . I'll be doing the day-to-day showrunning. We've also got a great crew of undergraduate, graduate and postgraduate scholars who will be generating the interviewing, editing and discussion content that we will share with you all each and every week.

We've got several episodes which are nearing completion and I will be delivering these to AFM this week. As a Canadian Planetary Scientist, I'm excited to have a radio home all our own and I look forward to sharing all the great work being done within our community with you all every Monday night!

A Presentation and some MSL Preliminaries

The cover slide for my upcoming presentation on MSL, the 2012 kick-off to the Planetary Science and Exploration Research Forum (better known as PSERF) at the University of Western Ontario's Centre for Planetary Science and Exploration (CPSX). Check it out this Thursday, January 12 at 12:30 PM in Biological and Geological Sciences Building room 1084.

Another Good Omen?

The launch plume from MSL's Atlas-V. The input of water vapor into the normally dry mesosphere (at altitudes of around 80km) causes very high ice-water clouds known as "noctilucent" clouds to form. We contemplate the shapes we see in the sky and like the ancient Romans, trying to read auspices, we hope to glean the relevance to our own future of such ephemeral and changing patterns.

On the morning of November 26, as we were boarding our busses to head to the MSL Launch viewing area near the VAB, the brilliant sunrise lit up the light, misty rain we had passed through on the causeway over towards cape canaveral. The refraction through the particles generated a vivid rainbow which seemed to touch the ground in the general direction of pad 41, where the Atlas-V rocket that MSL would ride on its way to Mars was being prepared for departure. We took it as a good omen, and a few hours later, everything went right with the launch.

Meet the Team


My UWO MSL Team. From left to right we are Raymond Francis, Emily McCullough and John Moores. David Choi is not shown, but you can take a look at him below.

As of last Wednesday I can say that I am a Participating Scientist on the Mars Science Laboratory Mission. That mission launched successfully last Saturday and we're now on our way to Mars. In the meantime, we have work to do. There are models to test, training for operations to complete and data reducing software to write. I won't pretend that I can get this all done by myself in the next eight months. Luckily, I don't have to. I've got a great team behind me and I wanted to help to shine a spotlight on them and what we hope to accomplish together - they deserve it!

Words just cannot describe this...

So I won't even try. 
Mars Science Laboratory is shown here in this picture I took at the parking lot of OFB-1 (our shelter in case of a launch failure), near the VAB at Kennedy Space Centre and 6 miles from pad 41 at 10:02:09.2 AM on Saturday, November 26, 2011, 9 seconds after the main engines of the Atlas-V started it on its way to Mars. Best of luck, little rover - our thoughts, prayers and hopes go with you.

Marking Time in an Astronaut's Playground

On today's tour we got the briefest glimpse from the coach of MSL sitting across the bay on pad 41. We're all suited up and ready to go!

I knew that I would only be able to stay in Florida for two days, so I picked the 25th and 26th in the hopes that the launch would occur within one of the first two windows. However, with the battery failure in the Atlas-541 abort system, the launch was pushed back one day to the 26th. This opened up a hole which SMD graciously filled by adding a Kennedy Space Centre tour to our schedule. We got to go to some interesting places that the public doesn't always get to see and we were pre-cleared for the launch and issued special MSL VIP badges. You can take a look at some of the pictures I took (now updated with images from launch day!) along the way today.

Dreams and my Date with Destiny


When you were a kid, what did you want to be when you grew up? Amongst us planetary scientists, the answer is almost always: "An Astronaut." I can certainly understand the appeal. Who wouldn't want to explore an alien place and do it in the style with which we associate Buck Rogers, Captain Kirk or any of our other intrepid science fiction heroes?

But that doesn't quite capture what I imagined at that age. Let me explain what I mean by that statement by using an example. When I was much, much younger, my parents allowed me to stay up for one show alone - NOVA on PBS. It was a real treat because the show came on at 9:30 PM in Newfoundland which is pretty late for an eight year old. For those of you who know the show, there's quite a variety of topics that end up getting covered from medicine to military technology and everything in between. 

However, I did have a favourite episode. I just couldn't get enough of the results that came back from the Voyager probes. That story had everything: cutting edge tech, an audacious plan with dramatic twists and turns, and wonders revealed that felt so much more satisfying than anything from SciFi because they were actually real. Central to the whole process was the mission controller and that holy of holies for me, the Jet Propulsion Laboratory. Yes, I was one of those eight year olds who dreamed of one day being part of JPL.

Getting Ready for the Cape

MSL Arrives at Launch Complex 41 inside its 5m fairing just before dawn on November 3. In the days ahead, this fairing will be mounted atop an Atlas-V 541 EELV for a launch to Mars no earlier than November 25. 

After some consideration, I've decided to bite the bullet, take a chance and head on down to Cape Canaveral next week to help see off Mars Science Lab (MSL). Better known as the Curiosity Rover, MSL is an exciting mission to Mars that will take a close-up look at the km-thick layered deposits inside Gale Crater. It's an exciting place to try for and the rover team is looking forward to a successful launch, landing and the scientific results that will be returned. Unfortunately, I was unable to attend the spectacular night launch of Phoenix in 2008. So this will be my first launch, assuming that delays don't push the launch back until after I need to fly home.  While I have some idea what to expect from video and images, I have no idea what the experience will be like in person.

Dr. Hojatollah Vali's CATP Seminar

 Astrobiology's favourite martian meteorite, Alan Hills 84001 is shown alongside a Magnetosome, a bacteria that fixes iron within its body to form magnetite and gives itself a free ride (or orientation) courtesy of the Earth's magnetic field. Could the tiny magnetite crystals serve as biomarkers long after the host is gone? And what is the origin of these kinds of features in ALH84001?

Recently, we kicked off the CATP  seminar series for the 2011-2012 season! The first talk of the year comes from McGill University's Hojatollah Vali. Dr. Vali's work is mainly concerned with the ability of iron-fixing bacteria to serve as biomarkers long after the bacteria have long since passed away. It's just one way that we can answer the question of how to detect past biological activity in the absence of well-developed morphologically distinct fossils.
