Time to get some new assets at #Mars, we need some new #orbiters for sure. Losing #MAVEN, if it can't be recovered, will be a major blow to operations.

NASA just lost contact with a Mars orbiter, and will soon lose another one
If NASA is serious about exploring Mars, it’s past time to send new missions.

I'm considering doing #OralExams for my #Mars course next semester, one way to do #AuthenticAssessment in the age of #AI. Trying to figure out the logistics and how to assess individual performance as I'll have to do the exams as small groups.

Let's be clear, a technology company wants to do this; scientists are against this. If you want to harness solar energy in orbit, then do it in orbit. #SBSP #SpaceBasedSolarPower #solar This proposal is bad for #astronomy, for the #environment, and for #wildlife

A great example of the limitation of #AI "thinking" and "understanding" which harkens back to the #CopernicanRevolution. I like this as I prepare to teach my #Mars class next semester. (And spend so much of my time on @sunyofficial.bsky.social AI projects.)

As someone who grew up in a working class household in IA, I would like to see Democrats spend more time focusing on pocketbook issues that allow everyone a path to a decent livelihood. It's discouraging how we have lost support among working class voters.
