December 20, 2025 was finally the day.
I have been at the PVL for over 2 years now, and while projects and some people have come and gone, one thing has always remained constant: our PVL lab room has looked like my bedroom when I was 7. Because we work in planetary sciences, we have a wide variety of equipment – from optical equipment to vacuum chamber components to flow tubing to spectrometers to regolith simulant to various chemicals. And that is before we get to all the non-science items in the lab, like books and files, as well as that big Venus globe!
Keeping all these things organized is difficult, with so many different projects in and out of the lab. And at times, motivation to clean can ebb and flow, both for me and a lot of other people. But, on the week of December 15, just one week before I planned to leave town for the winter holiday, I decided that it was finally time to get down on it.
It started when we needed to pack up our Martian Atmospheric Gas Evolution (MAGE) experimental breadboard spectrometer and send it back to our industrial partner, ABB. Abby and I had collected a pallet and ordered some bubble wrap and shrink film a few weeks prior, and on December 16 we put those materials to use (below). Shipping it out via LTL freight, which happened on December 19, only 2 days before I left for the holiday, was a significant step towards making the lab genuinely clean. This was not just because it had been sitting in there for a few weeks and was crowding our lab, but also in the process of shipping it out, we cleaned the lab upstairs (which belonged to a different group and was where we conducted most of our experimentation with this spectrometer).
Sending it out freed up a little bit of space on our optical table. Nonetheless, there was still a significant amount of optical equipment and other things lying out - tools strewn everywhere, old boxes/cardboard, tubing pieces from the spectrometer setup, etc. Even our chiller still contained ethylene glycol-based antifreeze from a project that occurred several months ago.
It seemed like such a massive task that maybe we were beginning to accept the constant state of clutter. However, in many cases, constant clutter in a laboratory is a safety hazard, because it impedes the ability to conduct experiments in an organized fashion, and introduces issues like tripping and spilling hazards. So, on December 20, with my flight out of Toronto less than 24 hours away, I drank a cup of coffee, put in my earbuds, and somehow just got into the zone. I went through the lab putting away tools, taking apart optical equipment, wiping down counters, and throwing away scraps. I officially started a “Sharps” disposal box for our lab (we were starting to use glass pipettes on a regular basis) and also started and labeled waste disposal containers for the ethylene glycol. I also started a “Misc/I don’t know” box. This box is for all the things that are probably optical components, but I am not completely certain of exactly what they are or how they are used in optical setups. “Misc” is a Swiss-army knife of a lousy excuse for a box label, isn’t it?
The lab is far from perfect so far. We still have 2 desks in the back of the room that are filled with miscellaneous computer equipment, the corner next to the door is overflowing with old poster tubes, and the floor could use a sweeping. But, when cleaning a lab, just like in conducting scientific experiments, progress is always incremental. I forgot to take a “Before” picture, but the “After” picture is at the top of this post. It will keep getting better, too.
Two final thoughts:- For what feels like the millionth time, our lab’s tape measure has gone missing. It might be time for another trip to our local hardware store.
- During this day, I listened to a lot of what I would call “indie EDM” and a lot of the songs made me think of outer space. We need to start making a PVL playlist/mixtape.
