- Somebody asked me the other day if anyone was running against Betty McCollum in the primary. Apparently the answer is yes. Aswar came to speak at my precinct caucus. www.aswarforcongress.org

- Thank you for asking that.

- If he ran for Minneapolis mayor, did he switch districts just to run for Congress?
- Sometimes I encounter people who pretend that spacecraft operators can hide where their spacecraft are. Then I remind them of things like this:
- 🌙 On this day in Jodrell’s history... In 1966, the first close-up photographs of the lunar surface - taken by the Soviet #Luna9 spacecraft - were received at Jodrell Bank, with help from an early type of facsimile machine (a picture receiver) borrowed from the Daily Express newspaper. 📸: JBO / UoM

- I lately heard from an emergency responder around here how he has had to explain to people that 40 mm launchers throw projectiles with about the same energy as a fastball and can cause equivalent injuries. I do not like needing to know that.

- Metaphor check: Without looking it up, do you know what the Rosetta stone is and why it was important?
- Yes, but I feel like working at SETI will produce skewed results.
- #ImpeachNoem. And also dismantle DHS, making FEMA an independent agency again.
- Not anywhere near enough. Yet again, USA: Require that your members of Congress do their jobs, end all of this, remove Homan & Miller, #AbolishICE & the Border Patrol, #ImpeachNoem, and #ImpeachTrump. Give them no choice otherwise.
- Listening to a presentation about the asteroid impact hazard. Speaker: "Nobody likes to talk about nuclear blast disruption." Scientists and engineers have been talking about that for the last 35+ years. It just fortunately turns out to not be necessary.

- The risks from a lunar impact are concentrated on spacecraft in lunar orbit, where the ejecta density is high. Ejecta escaping the Moon and going into Earth orbit would contribute measurably to the background meteoroid density. For one analysis: arxiv.org/abs/2506.11217
- Some good news. Now #CloseTheCamps and #AbolishICE "Columbia Heights fourth-grader and her mother released from ICE detention after school officials call attention to her case" sahanjournal.com/education/co...
