Come and Learn the Art of Exploration

The author takes a selfie with the Curiosity Rover at NASA's Jet Propulsion Laboratory, one building over from Curiosity's Mission Control where he worked during the summer of 2012. We hope to give those who attend our event on May 27, 2017 a taste of what running a space mission like Curiosity is really like.

Last year I was fortunate to be successful in my bid to secure an Ontario Ministry of Research and Innovation Early Career Researcher Award. In addition to allowing me to expand the Curiosity (Mars Science Laboratory)-related work that we do in my group, this particular award has a youth outreach component that we're about to roll out for the first time. I think we've put together a really interesting day if you want to get an idea of what it's like to do real planetary exploration. I know that my team and I are really looking forward to sharing our enthusiasm with those students who join us on Saturday, May 27!

Some of you may have navigated to this post in order to get more information on the event, so this will serve as exposition. Over the course of six hours, from 9:30 AM to 3:30 PM, we hope to give you all a little taste of what science-driven mission design is like. The "science-driven" component is important because, where space exploration was at one point focused purely on pushing boundaries (what we call "footprints and flags"), the modern version has an animating purpose in mind, and that purpose is the science that is returned. Think of it as the difference between John Cabot's "Matthew" and Charles Darwin's "Beagle." We will start with how you select a landing site before describing how you go about equipping a robot for the journey and then how that robot is operated on another planet to actually accomplish science goals. In each case, it will be you and your fellow students who make the choices.

A Banner Conference

 
While twitter is going somewhat crazy over Jake's videos, especially the gravity wave one, this one is my favourite, not only for the patterns in the clouds, but also for the shadow cast on the foothills of Mt Sharp. While this development was the most unexpected success of the group at this year's LPSC, it was far from the only event that made this a conference to remember.

I've just returned from 2017's Lunar and Planetary Science Conference (LPSC) held this year, as every year, in the Woodlands, Texas. No matter which way you cut it, this year's conference was a tremendous success for PVL. That's not hyperbole, despite the fact that LPSC holds a special place in my own Planetary Science Education (the 2004 edition was where I realized that I wanted to be a planetary scientist) and it's an excuse to spend a week in 25C+ weather in the middle of March and meet up with old friends from graduate school.

There were a few things we knew coming in would make this year a banner year and a few surprises that heightened the experience.

A surprising, serendipitous turn of events - the making of a Nature Paper

My new favourite planet (don't tell Mars!). This post tells the story of how the Nature penitentes paper came about. A previous post described our findings in plain language. I must apologize in advance, the length really got away from me on this one. But I hope the tale which follows is instructive for other early career folks in the planetary sciences (and other disciplines) who have a flash of inspiration that leads them towards high-impact publishing and who are not already members of science teams.

If you have to blame someone, blame Geoff Languedoc*.

Penitentes on Pluto


Though not posted until after the embargo clears, I'm writing this post over the winter holidays out in Gander, NL. It's plenty cold, snowy and icy, but far too windy and humid for Penitentes to form here! The image above was captured by the Ralph/Multispectral Visual Imaging Camera on the New Horizons Spacecraft in July of 2015. The image shows the Tartarus Dorsa region of Pluto which has been sculpted by the sun into a regular pattern of icy blades.

This post is intended to offer up a few details about my recent article that appeared online in the January 4th edition of Nature. You can navigate to the paper itself using this link and the York and NASA/APL press releases are also linked.  Because Nature articles are very information rich, I was thinking that an unpacking of my recent article might be helpful to some of my readers out there. Note that how this article came to be may be the subject of a separate but related post which I'll post once things calm down a bit. Instead, this post focuses on the content of the paper and you can read more down underneath the cut.
