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

Some incredible transparency from @NASAAdmin @rookisaacman regarding the Starliner crew fiasco. It will not fly again until the ROOT CAUSE is addressed, not just bandaided. I don’t see how this is can be worth it to Boeing anymore TBH. They have to be losing money on Starliner

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.

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: time.com/7346146/artemi…

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.
Austen Allred@Austen

I’m very excited to announce 🇺🇸 Gauntlet for America 🇺🇸 Our country needs AI-native engineers, and the U.S. Government is looking to Gauntlet AI to provide that capability. This is a COMPLETELY FREE, all expenses paid fellowship to prepare for high-stakes public sector roles.

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.

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.

BREAKING: Missouri Attorney General @AGCHanaway responds to our reporting— demanding an explanation from @BJC_HealthCare on policy REVOKING parents’ access to their kids’ medical records when the kid turns 12.

Libs of TikTok@libsoftiktok

Missouri based @BJC_HealthCare revokes parents’ access to their kid’s medical records when the kid turns 12 because it’s “confidential.” Kids must grant written permission in order for parents to view it. Kids can make “private medical decisions” and revoke parents’ access at any time. 🚩🚩🚩

This is REAL (and I can’t BELIEVE we pulled it off)! It took months of planning and a stupid amount of math, but I couldn’t be happier with the result! Best skydive of my life! Thank you @AJamesMcCarthy for immortalizing it! ☀️🪂🔭

Immense planning and technical precision was required for this absolutely preposterous (but real) view: I captured my friend @BlackGryph0n transiting the sun during a skydive. This might be the first photo of it's kind in existence. See a video of this moment in the reply 👇
