De-mystifying Martian Clouds
Planetary Volatiles Laboratory
by
2d ago
 Two of the lab's PhD students have just published analysis on how Martian clouds interact with sunlight in companion papers over in the Planetary Science Journal! The results represent work on thousands of images of the sky taken by the Curiosity Rover over more than ten (Earth) years and describe the thickness of the clouds we saw and give information on the crystals that make up those clouds. How can you use pictures of clouds to figure out what they are like on the scale of less than a thousandth of a cm?

The Crunch
Planetary Volatiles Laboratory
by
2M ago
There comes a point when working on any large project when you can run into roadblocks or motivation can flag. This is almost guaranteed with something as long and as challenging as a PhD. Indeed, statistics suggest that in Canada about a quarter of science and engineering PhD students do not complete their degrees within 9 years (as of 2013). Sometimes, the greatest challenge can arise just before the end in "The Crunch" to finish, as Dr. Kevin Axelrod, our new Postdoctoral Fellow attests in this week's very personal post below. But if you find yourself in this situation, don't loose hope ..read more

The Center of the Universe – My Experience Interning at the Jet Propulsion Laboratory
Planetary Volatiles Laboratory
by
4M ago
We often encounter kids in our outreach work who can't wait to be astronauts when they grow up. Somehow this didn't have the same pull for me. Instead, I was mesmerized by the robotic spacecraft  exploring the distant reaches of the solar system. One facility came up over and over again in watching documentary after documentary on PBS about those probes: NASA's Jet Propulsion Laboratory in Pasadena, California. It was a thrill to visit while I was in graduate school. I still don't think I'm completely recovered from having a badge and a parking pass during the 90-sol prime mission of MSL ..read more

Completing an Internship at the Canadian Space Agency (CSA)

by
9M ago
Last fall and into the winter term, PVL PhD student Charissa Campbell completed an internship with the Canadian Space Agency. Internships with industry, other academic labs and government are a key part of life at the PVL, giving graduate students the opportunity to get to know career paths close up during their studies. (Above: CSA headquarters in St-Hubert, QC with the Agency's new logo in the top-left corner) By Charissa Campbell From September 2022 until April 2023, I was completing an internship at the Canadian Space Agency (CSA) on top of my grad studies. Being a part of the Technologie ..read more

Coffee Cupping for the Novice
Planetary Volatiles Laboratory
by
1y ago
  Ahh, coffee! It's practically a religion in science. Cups often fuel a late night working on a proposal or finishing a paper. Carafes are never far at research seminars and conferences. Chances are good that when you last made a new collaborator they were holding it in their hands. While some aren't picky about what they drink, others have very defined preparations and purveyors. For this week's post, PhD student Elisa Dong decided to take a deeper dive and reports back on a coffee cupping event that she recently attended. (see the bottom of the post for a description of the image abov ..read more

James Webb Space Telescope Update

  The James Webb Space Telescope is able to view the universe in a truly new light. Below, MSc student Madeline Walters takes a look at some of the recent discoveries this new observatory has made. Image above: https://images.immediate.co.uk/production/volatile/sites/25/2022/01/JWST-galaxies-ba2f7b8.jpg by Madeline Walters It’s been a while since my last Webb update, but since then the space telescope has been busy! To kick off 2023, NASA released a statement [1] about how the James Webb Space Telescope (JWST) was used to capture the shadows of starlight cast by the thin rings of Chariklo ..read more

The Next Generation of New Frontiers Exploration
Planetary Volatiles Laboratory
by
1y ago
NASA has several different space mission classes for exploring our solar system. These are arranged by funding level as well as by how quickly they can respond to new science. Discovery provides the least funding but is meant to respond to discoveries that may not have even been made at this point. The medium class, New Frontiers, consists of a list of exciting destinations set out in the planetary decadal survey, the latest of which was just completed last year. The largest missions are run directly by NASA and respond to deep and meaningful science questions that cannot be addressed under t ..read more

My Summer Trip to MARS
Planetary Volatiles Laboratory
by
1y ago
This past summer, PVL PhD student Alex Innanen traveled up to the high arctic (on an expedition led by Prof. Haley Sapers) to test an instrument called MAGE which may someday fly to Mars. Ironically, the name of the research base at which they were stationed is itself named MARS! Given the harsh conditions, the name is perhaps merited and many space agencies use this area to test out technologies they hope to use in exploration activities. (Image above: MARS as seen from up on Gypsum Hill. You can see the edge of Colour Lake below, and Wolf Mountain rising above the ridge, with Crown Glacier ..read more

Hitching a Ride to the Moon (and Beyond!)
Planetary Volatiles Laboratory

1y ago
 Above, a series of ten 6-U cubesats can be seen attached to the ring which interfaces between the top of the Space Launch System (SLS) rocket and the payload fairing. It's not unusual these days for spacecraft to use extra mass allowances for these sorts of ride-along launches. It would be very difficult to arrange a special launch just for those spacecraft, so these larger launches provide a vehicle to considerably increase the science return from a space launch and to provide access to (deep) space to others. Here at PVL, we're very excited about the coming small-space era in Planetar ..read more

What’s going on with methane on Mars?

This week, Madeline discusses a critical component of her research into how methane is vertically distributed in the martian atmosphere. Read on for some details about the present state of the ongoing debate about Methane on Mars. (Image source: https://mars.nasa.gov/system/feature_items/images/6037_msl_banner.jpg) by Madeline Walters On Earth, we’ve often heard of methane being produced as a result of living beings-microbes that help with livestock digestion. Though when we found methane on Mars, we were puzzled by its origins. Are there microbes helping the digestion of Martian cattle? Most ..read more
