Wow, hello new people! An intro: I spent many years at NASA JPL researching polar ice on Mars; doing spacecraft science operations for Cassini, Phoenix, MRO, & Curiosity; inventing science ops for Perseverance; & working w/ Earth disaster response folks. I am currently a public speaker + artist.

At the end of last November, I walked along that path! We started at Ginkaku-ji, found Honen-in by accident, stopped for our first-ever okonomiyaki at Okonomiyaki Zen, and wandered through a short hailstorm to wrap up our Kyoto visit at Eikando. Unforgettable and beautiful. 🍁

On this Trans Day of Remembrance, we remember the bright and courageous trans people whose lives were stolen by hatred. Their absence is felt across our city.
We will honor them by building a New York where every trans person can live safely, fully and freely.

Here’s an annotated version of our comet image.
We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.

My life has changed direction and I’m no longer in the field. But I’m always rooting for the HiRISE team, and am delighted that they still are putting a creaky old spacecraft through its paces.

After much testing + coordination, HiRISE imaged its 1st comet. But not its last! We repeated the whole adventure for C/2013 A1 Siding Spring, joined by most of the Mars spacecraft fleet. Planning for that was one of my last projects for MRO + HiRISE before moving to Mars 2020 Perseverance.

I was HiRISE investigation scientist (liaison btwn camera team + JPL) when Alan Delamere first suggested this for comet C/2012 S1 ISON. Alan was one of the original people involved in inventing and building the camera. I lined up MRO management + Lockheed Martin engineers for him to convince.

...then the camera designed to always have a (relatively) warm planetary surface filling the entire field of view has to take a picture of a very distant, cold object. The planning & processing s/w makes assumptions about what kind of pictures HiRISE takes and how MRO moves, so some is done by hand.

Congrats to HiRISE and MRO for doing it again!
This is an OUTRAGEOUS image because it involves taking a spacecraft designed to roll 20˚ side-to-side but mostly point down, and having it pop a wheelie to point the camera away from the planet... (🧵) #PlanetSci 🧪

The feds are escalating in Los Angeles. We've seen record high kidnappings and our communities are under attack. The media focus on LA has died down so electeds don't feel the need to even feign opposition.
People are out here fighting. We need all of us. Join the struggle. Defend your neighbors.

Key Findings: Exposure to a field-specific faculty sexual misconduct incident decreases degree completion in that field by 3.4 percent four years after the incident. This decline is driven by incidents occurring after 2015, among which we observe a 7 percent decline in in-field degree completion.

Now that the US gov is open, 3I/ATLAS images from the Mars-orbiting HiRISE camera will soon be out. My money is on them looking just like regular cometary images. If that disappoints you, scan the HiRISE catalog for spectacular Mars images like this one uahirise.org/catalog/

After days of careful consideration in which all the evidence was weighed and the witnesses heard, they made their decision:
Words and numbers are of equal value, for, in the cloak of knowledge, one is warp and the other woof. It is no more important to count the sands than it is to name the stars.

As all this disgusting Epstein shit starts surfacing more and more, I hope we don't lose sight of the fact that apparently every major media outlet knew everything and instead spent their time money and energy attacking the trans community.
