Very nice article about the Harvest Moon and lunar orbital dynamics. I can pass this around to everyone I know who thinks these moon names are just random. 😂

"NPR asked NASA whether the agency was aware the items were restricted when they were put up for auction, but the agency did not answer the question. A GSA representative said all bidders on the restricted items signed online statements that certified they were allowed to buy them."😵‍💫

PSI's Amanda Hendrix wrote a really great op-ed for the local Tucson newspaper about what's at stake in the fight against the president's budget request for NASA: tucson.com/opinion/colu...

Local opinion: Southern Arizona space science is in crisis
NASA science dollars generate $337 million in Arizona's economy each year, so the budget bill as written now would be a huge hit on the local economy.

It's the president's proposal, but my understanding is that since that is the FY26 budget, it would take effect Oct. 1, so they are planning now. I have been told, if a CR is passed, then that gives NASA broad flexibility to implement what the president wants, if within the continued budget.

I would also like to point out that while it is important to get numbers correct, the difference between 40%, 45%, 48% and 50% is not that different when considering the functioning of the center. And small differences could depend on details of retirements, contractors, etc.

I've worked on developing radars with people there for a decade. The entire program could come to a sudden end without ever having a capability to use the technology from all that work, which is incredibly wasteful.

This has just been weighing on me for weeks, and especially this week. I loved working at Goddard. People there were great and some of the most dedicated people I know. It's fundamentally non-partisan excellence in science and engineering. Everyone is busy there. And it will save virtually no money.
