@PhysicsCWRU Congrats all!

As an Iranian watching this rescue mission unfold, I was praying the American pilot would make it out alive, not just for him, but so the Islamic Republic could not use him as a bargaining chip or claim some twisted “victory.”

At the same time, I felt a deep envy.

Your government sent elite special forces, million-dollar aircraft, and moved heaven and earth to bring one American home. No hesitation. No excuses.

In Iran, the regime uses human shields and recruited child soldiers to clear minefields during the Iran-Iraq war. They treat their own people like disposable tools. They are now recruiting child soldiers as we speak.

The Islamic Republic has zero regard for human life. That’s the brutal difference.

One side risks everything to save their own.
The other sacrifices their own to stay in power.

This hits hard when you have lived under both realities.

This video is great doomer antidote.

Another masterpiece from @jasonjoyride

This is what real leadership looks like, saying the difficult truths plainly and with accountability. Every word is worth reading. Bravo @rookisaacman.

[Alexis Ohanian 🗽 @alexisohanian]

Do hard things. It took just 50 (hardworking and awesome) people to build the first independently developed civilian aircraft to break the sound barrier. @boomsupersonic [776] did that.

The signal strength hitting Earth from Voyager 1 is less than one trillionth of a watt.

To put that in perspective, your phone’s WiFi signal is roughly 100 billion times stronger, and it drops a connection walking between rooms.

NASA picks up Voyager’s whisper using arrays of 70-meter antennas, then reconstructs coherent data from it at 160 bits per second. That’s slower than a 1990s modem. Downloading a single photograph at that rate would take weeks.

The spacecraft itself runs on 8.8 kg of decaying plutonium-238 that generated 470 watts at launch in 1977. Today it produces roughly 200 watts, losing about 4 watts per year. NASA has been shutting down instruments one by one since the 1980s to keep the math working. They turned off the cosmic ray sensor just this year.

And here’s the part nobody’s talking about: there is exactly one antenna on Earth that can send commands to Voyager. Deep Space Station 43 in Canberra. It went offline for major upgrades from May 2025 through early 2026. During that window, if Voyager had a critical fault, the team would have had to wait months to respond.

A 48-year-old spacecraft built on 1970s computing, running on a plutonium battery that’s lost 60% of its output, transmitting at a power level that barely qualifies as existing, from a distance where light itself takes 23 hours to arrive. And a German observatory just casually picked up its carrier signal on a live stream.

The engineering margin NASA built into this mission was designed for 4 years to Saturn. Everything after that is borrowed time the engineers keep extending by doing math with 200 watts.

On January 28, we honor the seven crew members of Challenger - Dick Scobee, Michael Smith, Ron McNair, Ellison Onizuka, Judith Resnik, Christa McAuliffe, and Greg Jarvis - lost 40 years ago today.

We honor their legacy by staying vigilant, humble, and uncompromising in the pursuit of our world-changing missions.

[Steve Jurvetson @FutureJurvetson]

TIME to get excited 🌏 🌔🚀
Artemis II is preparing for launch in early February, to go where no man, woman or Canadian has gone before. Voyaging farther than the prior record from Apollo 13, the crew will have views of the full moon in front of Earth, and a flyby like this breathtaking shot by the Japanese lunar orbiter spacecraft Kaguya.

TIME today: https://t.co/IBJlEvRQy6

And yes, the plan also includes a large-scale retraining of the engineers already employed by the federal government.

It’s a fundamentally new world, and if we want what is best for the country we all need our government to live in it.

God bless the USA.

@elonmusk @wef Keep it positive and visionary. People want dreams becoming reality!

The lowest estimate for yearly U.S. fraud tops $521 billion.

$521,000,000,000.

You work your entire life. Weekends and Holidays.
You pay half your salary to the government.
And it's handed right over to fraudsters.

[Lisa @lisas2001_st]

@bennyjohnson Is it “Mr. Dog - shit, we could have….” or “Mr. Dog Shit, we could have…” lol. Either way funny .

[Boom Supersonic @boomsupersonic]

This Wright Brothers Day, we celebrate the moments that redefined flight. From the Wright Flyer to XB-1, every aviation “first” is powered by bold ideas, grit, and people who push what's possible.

Illinois does the same at age 13 the result of specific legislation. Schools leverage it to provide “counciling” without parent notification for a certain number sessions, state facilitates uninformed abortions and the list goes on. I would suspect they’re using state regs as cover. Explore POA arrangements for your teen.
