Hello BlueSky! I’m a spacecraft systems engineer, currently working on crewed moon landers. I’ll mostly be lurking around here, appreciating your space, science, and engineering related content, and maybe occasionally sharing a mediocre astrophoto of my own now and then. See ya around! 🦋

NASA's Jet Propulsion Laboratory to lay off about 550 workers

NASA's Jet Propulsion Laboratory said on Monday it will cut nearly 550 jobs as part of a restructuring, not related to the current U.S. government shutdown.

Tomorrow about a third of Perseverance rover staff will be laid off, despite the mission being the penultimate step in a decades long effort to bring samples back from mars.

Reckless, needless budget cuts intended to hinder the pursuit of knowledge.

Okay, if you were Reed Timmer, where would you go to zero meter a Southern California tornado? The 405? The 101? The 10? South Coast Plaza? The Getty?🤪 #tornado #cawx

🔭 Bricolage de ces derniers jours : PANOPTES 🤩 C'est un petit télescope automatisé pour détecter des étoiles variables. On le fabrique à Callista à l'EPFL 🇨🇭 mais c'est un projet international pour sensibiliser des élèves des pays du Sud Global aux sciences en leur faisant fabriquer et opérer 🧪

Télescope PANOPTES quasiment terminé sur sa monture. Il ressemble à Wall-E avec ses deux gros yeux

Over on Mastodon, I have found a lot of people who are interested in the SuperNova Early Warning System.

Emails and texts to be automatically sent in the event of the neutrino detectors all spiking at once, to give advance notice for anyone who wants to see the flash: snews2.org

Explain your username:

IRAS 07572-3100 is a star that had a huge infrared brightening beginning in 2015 and created a new nebula. I discovered that brightening and the nebula. (see also www.astronomerstelegram.org?read=14416)

You glow girl! ✨

At NSF–DOE Rubin Observatory, the secret to achieving a glowing-from-within look is our calibration screen.🔭 🧪

It's glamorous, we know 💅

An ominous blue donut-shaped ring surrounded by a thin red ring glows ominously in the dark to the left. To the right, Rubin's large steel telescope mount structure is barely visible, softly illuminated by the glow.

An #asteroid passed just 300 km above Antarctica earlier today. It was not discovered until hours after close approach.

“images” meaning artistically-rendered contour lines, intentionally misconstrued by the black hole imaging team as direct observation “photos”, implying they resolved discrete structural features in 1000x finer resolution than the underlying observations. The science is awesome. The PR is shameful.

seem to be a mixup. This makes no sense (article does not substantiate the claim)

Ryan Kinnett @rkinnett.bsky.social · 18d

What are you talking about? The quoted email says nothing whatsoever about layoffs. Where did “as many as 4,000” come from?

I'm hiring 1-2 postdocs this year! If you're interested in:

GW astrophysics
(Binary) Stellar Evolution
Stellar dynamics (esp. w/ massive BHs)
Galactic dynamics (inc. stellar streams)

plz consider applying! You don't need letters initially, just a list of references.

Last night it fogged over but I left the camera running in case it cleared. Woke up to an hour of the Ring Nebula (M57). I'm showing it starless and in an uncropped version for a reason. All the stars have been removed. Every point of light you see is a galaxy. #astronomy #astrophotography

Yesterday Curiosity took pix of jagged peaks in the distance with its ChemCam. I stitched them together, did some work on them, and... just look at that view... I've been doing this since Sojourner landed & this is one of my fave images ever... Credits: NASA/JPL-Caltech/LANL/S Atkinson
