Venus is a Solar System enigma.
Although Venus is similar in size and distance from the Sun to Earth, it has evolved very differently from our planet.
Our #Envision mission will aim to solve some of the puzzle by thoroughly studying our closest neighbour.

Every conference facility has its quirks. In this case I was at Saturn (room) and need to head back toward the Sun (room) but am not sure how. Maybe I need help from a dynamicist! #epscdps2025

I really wish there were fewer mistakes in Arizona governance. Please everyone come to work and try to make sure you do your job correctly. Maybe double check the letters, just for example.

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.

Wow! Amazing!
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.
NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...
NASA begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom
NASA employees have until July 25 to decide if they'll stay or go.
