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.

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 🧪

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/

Could someone let the potential head of NASA know that the answer to his question, “What is ‘built’ at JPL?”, is
Spaceships.
They build spaceships that explore other planets.
Seems like a good thing for NASA (and makes the country look extra rich and smart, if that moves the needle for you).
