So sad to hear that the iconic, trailblazing, Apollo 11 moon landing software engineering lead, Margaret Hamilton, is no longer with us. Love this image of her, standing next to a print out of the software that landed Buzz Aldrin and Neil Amstrong on the moon! 👩🔬🔭🛰️🧪

![4-panel comic. (1) [Person 1 with ponytail walking in with a second person. A third person with short hair stands behind a machine labeled “Detector” with a glowing green light for “detected” and a blank circle for “not detected.”] PERSON 1: Over there are our electron microscope, XRF scanner, and mass spectrometer. And this is our most sensitive detector. PERSON 2: What does it detect? (2) PERSON 1: Lots of stuff. Gas, dust, particles, light, radio waves, gamma rays, protons, neutrons, electrons, fields, forces, events, potentials, or states. (3) PERSON 2: I don’t understand. Aren’t most of those *always* present? PERSON 3: Yeah, it’s been saying “detected” continuously since we turned it on. (4) PERSON 2: What happens if it says “not detected”? PERSON 1: Oh gosh. PERSON 3: That would be pretty bad, I think.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreibfvjbd3aulnp3oekwon4ybg533uakzuoozawmnsunizaxj3imtqu)
![4-panel comic. (1) [Two people in a room with bed and nightstand. One person points at something on ceiling.] PERSON 1 with short hair on top of head: What’s that device? PERSON 2 with ponytail: Part of the supernova early warning system. There hasn’t been a Milky Way supernova in over a century. Astronomers don’t want to miss the next one. (2) [Person 2 sits on bed.] PERSON 2: 20 years ago, we set up a supernova alert system using neutrino detectors. It should give us a few hours’ advance notice. (3) PERSON 2: If it ever goes off, every astronomer on Earth will scramble to point their equipment at the sky. PERSON 1: Oh, Ok. So is that a detector? Or some kind of telescope? (4) PERSON 2 [leaving]: Fireworks launcher. I *refuse* to sleep through a supernova. PERSON 1: I think I’ll spend the night at my place instead.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreieib3sjwqtdeaedpuit6ewx4mm56j3nzcvfqpwbtzifnvsvtp6rde)
