I would stop, but I have to put in a good word for NASA and how it selects and funds science. I'm starting to think maybe Avi Loeb doesn't know what he's talking about?

At the #HWO25 conference this week to discuss the science and technology of the Habitable Worlds Observatory! Happy to answer questions here or in person if you can find me!

If you think potentially finding life on another planet would be a transformative event for humanity (not to mention all of the other discoveries HWO would make) call your Congresspeople and tell them you want HWO to happen!

Since 2009, I've been working on various teams thinking about how to build this kind of mission, and we're finally taking the first steps towards making it a reality.

NASA’s Habitable Worlds Observatory Will Search for Life
YouTube video by NASA Goddard NASA’s Habitable Worlds Observatory Will Search for Life

Do you want to hear Gimli narrate a video about the search for life in our universe? Of course you do!

The Habitable Worlds Observatory project is still in its infancy, yet paradoxically it's the project I've worked on the longest.

This test simulates the vibrations the system will feel during the short trip to orbit. We just completed the metrology verifying that nothing moved out of alignment during the test, indicating we have a robust system!

Put another way: Roman will collect more data in the first month of operation than Hubble has collected over its entire 35-year lifetime (so far).

Great timelapse of the #RomanSpaceTelescope coming together! Most of this happened in about a month and a half right before the holiday (the exception being the installation of CGI, which happened earlier in the fall).

We'll stay in this configuration for about a year, running through a battery of electrical and environmental tests to make sure everything works and can survive launch, before the final assemblies are added to complete the Observatory.

Finally, if you're interested in homebrewing, "How to Brew" is a must have. While Papazian's "Joy of Homebrewing" is a great place to get started and learn the ropes, "How to Brew" delves much deeper into the science and art of brewing, and provides all the tools needed to brew great beer.

Nor the legacy of women in science that she left behind. That being said...this book was a slog. I liked Sobel's writing in "The Planets", but here it was just...not engaging at all.

A learned a lot from "The Elements of Marie Curie". Aside from her winning two Nobels, I only vaguely knew she was involved in the discovery of radium. I never appreciated the extent of her contributions to physics, chemistry, and even medicine (especially during WW 1).

I picked up Scalzi's "Starter Villain" after reading "Kaiju Preservation Society" last year, which I really enjoyed. I didn't like "Starter Villain" as much, but I enjoy Scalzi's style and am interested in reading more of his stuff in the future.

But this is classic Weir: preternaturally smart, wise-ass main character is stranded in life-threatening situation and just happens to know all the random things they need to MacGuyver their way out. If you enjoyed The Martian, you'll like this, but don't expect it to blaze any new literary paths.
