Under the proposed White House budget, the NASA Space Grant program would be eliminated.
I was a NASA Space Grant recipient during my Masters—it funded my research on water on Mars.
I then went on to work in science & mission ops on multiple NASA Mars missions immediately after graduation. (1/2)

My first Mars mission ops job was "targeting" the Context Camera (CTX) aboard NASA's Mars Reconnaissance Orbiter. This meant picking what the camera took pics of everyday & then analyzing those images when they came back to Earth. This was the 1st photo I ever took of Mars: Pits on Arsia Mons. (1/2)

Not sure if there's a public U.S. example yet, but there's a case I know of in the UK where GHGSat data was used to spot + repair a pipeline leak! More info:

I love how hard IM and NASA tried to frame this as "successful" in the press briefing yesterday...meanwhile the stock market certainly disagreed.

Super sick right now but managed to hold in coughing and sit upright for a couple of minutes to talk with Al Jazeera live about the U.S. commercial lunar space race.
AJ: What do these companies want?
Me: Government money.

After seeing more than a few dismal responses from universities in the current dismantling of science in the U.S., I want to applaud this email from the chair of my alma mater, the University of Washington Astronomy Dept. 🔭

Tomorrow I'll be discussing why now is a critical time for scientists to consider career paths beyond academia. This will be a raw, honest discussion about the pros & cons of industry/entrepreneurship, & how to navigate those worlds as an academic.

Thank you to the University of Toronto Scarborough TEDx organizers for asking me
to close out their event! I hope some
folks left with a new appreciation for why exploring Mars matters even if it turns out there was never alien life there. 🔭

Mars is getting a lot of hate online these days thanks to Musk, and that breaks my heart. I hate that the awe and wonder around space that was once captured by inspiring voices like Carl Sagan has now been so thoroughly corrupted by the likes of space billionaires. 😔

For context, I am currently a Senior Science Advisor at GHGSat. They are a Montreal-based company with a constellation of 12 satellites that do point-source methane emissions detection at high resolution (can detect sources that emit >100 kg/hr). 🌎
