It's more than a miracle, it's proactive intervention and progress driven by both curious minds and advocates for safety. It's decades of unending cumulative effort by engineers, pilots, and regulators to make their next flight their best one.

Perhaps one of the greatest modern miracles of society is how safe flying has become.

Today was another excellent #RWRI presentation and Q&A session! Every year pushes what not just what the participants learn but what I learn as well. Great discussions on general aviation, commercial, spaceflight, and more!

Rather kind words for the Canadian member of the crew.

Yes there is! This is a great question. In short, SLS and Orion have less Delta-V (fuel available to speed up and slow down) than Saturn V and Apollo did. SLS has more lift-off power, but carries less mass to the moon.

Is there a reason that Artemis II doesn't even attempt to get into lunar orbit and will be 4k miles from the surface? Apollo 8 in 1968 got within 60-70 miles

Artemis and Orion was designed to be part of a group of docked spacecraft for travel to and from low lunar orbit and the surface. Saturn V and Apollo, due to the unknowns of the 1960s, and design changes, had a lot of extra power to them.

Being able to stream Artemis II live from lunar space all over the globe from a phone is a technical marvel, but I do whish the background drone wasn't the same frequency as my tinnitus

They are in fact the only valid use of solids on a crewed spacecraft

A fun fact is that this thing weighs more than an entire Soyuz capsule. Don't use solid rockets in your manned space program, kids. Not even once.

how ironic this meme should spread in 2026 as a way to suggest women are vain when the US is currently being run by a man who can be singularly understood through the lens of narcissism and it's related desires (e.g., self aggrandizement, revenge, domination, grievance validation). even the ballroom is just an expression of his vainglory.

This photo is objectively amazing and historic- a human being looking backwards toward their home planet as they venture into space. This concept was once beyond our wildest imagination. But y’all just want to hate women.

Yesterday I put together a small group of friends, both old and new, to go out into the Atlantic on a boat to watch the SLS launch of Artemis II. I cannot stress how great of a choice this was, and highly recommend it as a way to watch liftoffs.

There are a huge number of valid criticisms of SLS, and there are points in both the past and future that cancellation is/was called for. However at this point a successful flight of Artemis II will be a massive benefit to all, from the smallest space company to NASA itself.

1.5 million names are flying around the Moon on Artemis II. Is yours one of them? It's not too late to add your name to the mission—and it's absolutely free: go.nasa.gov/artemisnames

One of the biggest surprises I've had on a road trip was seeing how lively Tulsa was
Jordan Werth@bottomsplitCEOJan 18
the highlight of this tulsa trip is seeing this building i had no idea existed!!!! a half scale replica of the original world trade center built in the late 70s by the same architect. wow!!!!

a 15 second check of the facts show that the airplane was either "fine" with a concerning errant sensor reading, or it was "not fine" with an accurate sensor reading. Both can be reduced to "not fine"

Pilot cancels flight due to safety concerns: "im not feeling it" A pilot canceled an American Airlines flight for one simple, brutally honest reason: “I’m not feeling it.” No dramatic engine failure. No weather chaos. No cryptic announcement full of airline jargon. Just a human being in the cockpit recognizing that something felt off—and choosing safety over schedule, pressure, or convenience. In an industry where delays spark outrage and cancellations trigger viral meltdowns, this moment is a reminder of what we actually want from the person flying a metal tube at 35,000 feet: self-awareness, caution, and the confidence to say no. Because “not feeling it” isn’t laziness—it’s intuition, experience, and responsibility speaking up before a problem has a chance to exist. We praise pilots for handling emergencies, but maybe we should praise them just as much for preventing one. So yeah, the flight didn’t take off. Plans were delayed. People were annoyed. But everyone walked away safe. And honestly? That’s exactly the kind of energy you want in the cockpit. ✈️ 📸 aviationmp4

This is the space section of a comprehensive analysis of China's industrial policy. China is good at seeing what works, copying it, and doing it more cheaply. China is copying SpaceX and Blue. They are NOT copying SLS or anything produced by the Primes. uscc.gov/sites/default/files…
