The Presidents Budget Request for NASA is out. It’s a bloodbath

Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision…

Huge cut to R&A. No funding to begin development of the Uranus Orbiter.

If you’ve ever cared about NASA, time to contact congress.

You have three days, starting today, to leave a public comment with the FDA about, say, why COVID-19 boosters should remain available to everyone and also free. "Individual consumer" is the category you most likely want (unless you are one of the other categories; if so, choose that).

I didn’t have earthquake on my bingo card as flight director for Europa Clipper this morning! Glad the early warning notification worked and luckily the shaking on the 4th floor of our mission control was very limited.
