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!
(As a quick note of technicality, if the
same system as Phoenix is in place all three will be considered "Science
Team Collaborators" or "Collaborator-Level Science Team
Members." I'll be able to update once I get a look at the MSL Rules of the
Road document.)
First up is an old friend from Grad
School, Dr. David Choi, most recently of the NASA Goddard Space Flight Centre.
David has spent his career studying the movement of clouds on Giant Planets and
we plan to build upon his work by applying this code to Mars. In doing so, we
should be able to extract the wind direction in any atmospheric image that
shows clouds of dust or water ice.

Spearheading this application is Raymond
Francis, a doctoral student at the University of Western Ontario in
Engineering. Raymond's speciality is image processing techniques and he will be
looking at each frame to determine which way the wind is blowing. Beyond our work on MSL, we would also
like to explore preprocessing of atmospheric data sets to allow a greater
fraction of the sky to be analyzed during landed planetary missions.
But we don't need to limit ourselves to
passive techniques. MSL has a powerful laser, the LIBS System for Laser-Induced
Breakdown Spectroscopy, a part of the ChemCam instrument. We can aim this
instrument into the sky and where there are sufficient particles, we should be
able to see the light scattering back from the particles within the beam. This
is very much like using a flashlight in the fog. By looking at where this
"backscatter" strikes the CCDs of the MastCam cameras we can tell the
range to the target and by analyzing the intensity, we can determine just how
much material is out there. We can then combine this information with microphysical modelling of the formation of ice as well as what we know about the condition of the ground ice from the Russian Neutron Spectrometer, DAN, and the water vapor content of the atmosphere from the Spanish weather station, REMS.

This application will be led by Emily
McCullough, a doctoral student at the University of Western Ontario in the
Physics and Astronomy department. Emily has worked with LiDAR techniques in the
high arctic, so Mars isn't a huge stretch from the environments she is used to. As well, where the images being used in Raymond's investigation are multi-spectral, we will be able to determine whether those particles are icy or dusty. Ultimately, we seek to find a relationship between the spectral ratios to help determine mixing ratios of ice and dust.

We've been lucky in the last few days to get some good press. I'll paste some links down here for those interested and so I can find them again later on!
