Serious questions are being asked.

This Zenith Movie was taken on Sol 1957 (2018-02-06) at approximately 7:09 LTST and a solar longitude of 125.8°.

The answer did (somehow) end up being the Crosstown, but it now appears that we'll never know what this rover's name would have been as the CSA is cancelling the mission 😔

just remember how insanely fast nature rebounded when everyone stopped rolling coal for 10 minutes in the early pandemic

Things that are really fun to think about while you're trying to decide what you're doing after you get your PhD :)

I love writing emails referring to myself in the third person. I have not been fundamentally broken as a person by academia.

...I don't think this is true?

This week, PhD Student @dchayes.ca sheds some light on how we talk to spacecraft on and around other planets: york-pvl.blogspot.com/2026/02/talk... The situation on the red planet is particularly complex and therefore particularly interesting! Like any infrastructure, maintenance is critical

Having to hunt down the source of an image claiming to be a photo of a sunset at Gale Crater because I know Gale Crater and this isn't her.

Fun activities for when you have a spare ~five hours in Toronto:

For many years, researchers were unable to independently verify the alleged existence of Line 5 Eglinton.

It has now been four years

Still on Mars with Curiosity. Still doing awesome science. Love this recent "MAHLI after dark" image we acquired last month of our drill in the super cool boxwork region: science.nasa.gov/resource/cur...

This has been one of the wildest things for me. Before I started E I was like "I don't really have dysphoria in any meaningful way," but after (almost) a year and a half I can look back like yeah I kind of really did, actually, but just didn't know how to identify it.

Google Scholar will be sending me articles from such reputable "journals" as "Collection of scientific papers."

Was filling out staffing availability yesterday and saw that my name had been changed, something that I cannot recall doing myself, suggesting that someone on the inside at JPL must have noticed and done it for me 🥹

Finally got course evaluations back for my first lab teaching experience and needless to say I will be riding this high for the next week.

Open Call for Proposals for International Teams in Space and Earth Sciences The International Space Science Institute (ISSI) and ISSI-BJ invite proposals for establishing International Teams to conduct collaborative research in the Space and Earth Sciences at their respective meeting facilities.

2025 ==> 2026 as seen by the York Observatory all-sky camera.

This is the only time of year where I can walk into a room to discover Anderson Cooper and Andy Cohen doing Heated Rivalry roleplay live on CNN.

Kudos to our project scientist who helps advocate for these every ~year when I think the view might work and we've got a little bit of energy and time spare in a plan. Doing the science on the day to day is important. Taking a moment now and again to do something just for art is important as well.

A little iridescent treat on the way back from the mountains.

Apparently Google will now let you change your email address without losing access to your account AND while keeping the old address as an alias for the new one, which needless to say is a gamechanger for me personally.

Sometimes you're reading a book that decides to violently smack you in the face with the fact that it was written by a straight man in the late 2000s.

Death, taxes, and getting stuck at Toronto Pearson International Airport for multiple hours.

Superb video included in today's JPL update for #PerseveranceRover (www.jpl.nasa.gov/news/nasas-p...). With synthetic frames and obviously, the rover doesn't move that fast, but the final result is impressive. Credit: NASA/JPL-Caltech

I beg your pardon

Proud to see the first paper (out in @agu.org JGRPlanets) from Dr. Campbell, the postdoc @sguzewich.bsky.social and I mentor. She did a spectacular job explaining the source of the odd dust activity (called the B-storm) during Mars's SH summer. #planetaryscience #Mars 🪐🧪🔭 doi.org/10.1029/2025...

Went grocery shopping this morning and discovered that they're now selling Kawartha Lakes ice cream in half-litre containers so I think we can say that today has been a tremendous success.

RIP V3cam 2025–2025 😔

Short but intense Toronto snowstorm this afternoon.

They've made St George Station transphobic 😔

3/3 Time to update the Gas Giant Portrait I created, now including the new versions of Saturn and Uranus I recently processed. Full size & more info: flic.kr/p/2oUkYSY 🔭🧪 Credit: NASA/ESA/CSA/STScI/AndreaLuck Jupiter is next on the list to be updated :)

This Zenith Movie was taken on Sol 3046 (2021-03-02) at approximately 17:39 LTST and a solar longitude of 11.11°.

What will happen first: The opening of the Eglinton Crosstown or the CSA announcing the name of their lunar rover?

Station maps might be getting updated, but everyone knows that the allegedly imminent openings of Lines 5 and 6 won't be official until the TTC adds them to their slow zones map.

Abstracts submitted to LPSC 2026 are required to comply with White House (non-legally binding) executive orders forbidding mention of topics related to diversity, equity, and inclusion. At least USRA/LPI isn't hiding it. But is this what our community wants? Or deserves? I don't think so.

Today's edition: My Google account, somehow? Not sure how that one evaded my attention for this long.

Now freed from purgatory following the end of the shutdown: I got to write about Curiosity celebrating seven Mars years of exploring Gale Crater, highlighting the occasionally overlooked accomplishments of our environmental science team. science.nasa.gov/blog/curiosi...

Kīlauea's really doing its best to beat its own height and volume records this episode.
