A little piece of advice for Americans navigating what will be an increasing number of posts about US politics in the coming year:

If a post makes you feel angry, upset, and hopeless, while offering no actionable information, scroll on and don't reblog it. I know that is going to feel harsh in some cases. But it's important to spend your political energy on what you can actually do and not be sunk into helpless rage and despair that benefits no one.

If I may, I must make the gentle request that people consult Wikipedia for basic information about anything.

I’m not entirely sure what’s going on, but more and more people coming to me saying they can’t find info about [noun], when googling it yields its Wikipedia entry on the first page.

I’ve said it before, but I’ll gladly say it again: You can trust Wikipedia for general information. The reason why it’s unreliable for academic citations is because it’s a living, changing document. It’s also written by anonymous authors, and author reputation is critical for research paper integrity.

But for learning the basics of what something is? Wikipedia is your friend. I love Wikipedia. I use it all the time for literally anything and everything, and it’s a huge reason why I know so much about things and stuff.

Please try going there first, and then come to me with questions it doesn’t answer for you.

Hey, a quick PSA:

Stranger Things is green-lit for its final season. It's not getting renewed anyway. Refusing to watch a show that's already being made does nothing of importance, just like how watching movies already being released did nothing to harm the WGA/SAG strike.

If you want to do something that will actually make some kind of difference you can:

Cancel your Netflix subscription and actually stop giving money.

Don't buy any Stranger Things merch going forward.

Boycott the companies that Palestinians are ASKING you to boycott. Boycott McDonalds, Starbucks, Disney+, and all the other companies on the list they GAVE you. Targeted boycotting is more effective, and these companies are directly supporting Israel.

Keep talking about Palestine more than you talk about Noah/Stranger Things. Keep the focus on Palestinians!

Click daily to donate! It's that easy!

I understand not wanting to look at Noah's face, because I'm right there with you. I don't want to see him either. But let's do things that really help.

The Nancy Grace Roman Space Telescope’s flight harness is transferred from the mock-up structure to the spacecraft flight structure.

Your Body is Wired Like a NASA Space Telescope. Sort Of.

If our Nancy Grace Roman Space Telescope were alive, its nervous system would be the intricate wiring, or “harness,” that helps different parts of the observatory communicate with one another. Just like the human body sends information through nerves to function, Roman will send commands through this special harness to help achieve its mission: answering longstanding questions about dark energy, dark matter, and exoplanets, among other mind-bending cosmic queries. 

Roman’s harness weighs around 1,000 pounds and is made of about 32,000 wires and 900 connectors. If those parts were laid out end-to-end, they would be 45 miles long from start to finish. Coincidentally, the human body’s nerves would span the same distance if lined up. That’s far enough to reach nearly three-fourths of the way to space, twice as far as a marathon, or eight times taller than Mount Everest! 

An aerial view of the harness technicians working to secure Roman’s harness to the spacecraft flight structure.

Over a span of two years, 11 technicians spent time at the workbench and perched on ladders, cutting wire to length, carefully cleaning each component, and repeatedly connecting everything together.  

Space is usually freezing cold, but spacecraft that are in direct sunlight can get incredibly hot. Roman’s harness went through the Space Environment Simulator – a massive thermal vacuum chamber – to expose the components to the temperatures they’ll experience in space. Technicians “baked” vapors out of the harness to make sure they won’t cause problems later in orbit.  

Technicians work to secure Roman’s harness to the interior of the spacecraft flight structure. They are standing in the portion of the spacecraft bus where the propellant tanks will be mounted.  

The next step is for engineers to weave the harness through the flight structure in Goddard’s big clean room, a space almost perfectly free of dust and other particles. This process will be ongoing until most of the spacecraft components are assembled. The Roman Space Telescope is set to launch by May 2027. 

Learn more about the exciting science this mission will investigate on X and Facebook.

I didn't think I'd be doing this again after I got my undergraduate degree, but it looks like I'm back on studyblr. Right now I'm doing some online classes, but I'm prepping some grad school applications and if those go well I will be a full time student again.

Like before, my posts will mostly be for me to look back on, and not too highly polished. Think of a journal about studying and you'll have reasonable expectations.

Today I did a session of my Interplanetary Spacecraft and Satellite Engineering course. I'm just wrapping up the section on different kinds of propulsion. At first I was skeptical of the quality and depth an online course could provide, but I think this course covers the main topics and gives you a good baseline to evaluate new ideas and go into more research on your own.

I've also been trying to get outside more often, the other picture is some salt ponds I visited last weekend.
