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.

[Colin McCarthy @US_Stormwatch]

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

@FooledByHistory There is still a degree of bad actions that countries do get away with, due to adversaries not wanting to upset the balance. But at the end of the day all but the most advanced sats are all easy targets, and nations want to keep their satellites so the status quo remains

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!

Publix has occupied that building 5 times longer than the Confederacy existed

[Chris Combs (iterative design enjoyer) @DrChrisCombs]

The future is going to be incredible

Rather kind words for the Canadian member of the crew.

[NASA Administrator Jared Isaacman @NASAAdmin]

Our closest neighbor in a seemingly endless universe. We have only just begun this adventure.

[Alexander Taleb @AlexanderNTaleb]

@alexlesuper That had been the intent, yes, but there is nothing more permanent than temporary. The full power upper stage was cancelled, and as of this week the interim stage will fly one or two more missions before moving to an only slightly better upper stage sourced from Vulcan.

[Alexander Taleb @AlexanderNTaleb]

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

[Alexander Taleb @AlexanderNTaleb]

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

[Alexander Taleb @AlexanderNTaleb]

Yes, SRBs are bad, next question!

[Alexander Taleb @AlexanderNTaleb]

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

[Pinboard @Pinboard]

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.

[derek guy @dieworkwear]

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.

[Alexander Taleb @AlexanderNTaleb]

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.

[Alexander Taleb @AlexanderNTaleb]

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.

[NASA @NASA]

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: https://t.co/tUAM7BTfjt

One of the biggest surprises I've had on a road trip was seeing how lively Tulsa was

[Jordan Werth @bottomsplitCEO]

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!!!!

Americans would be 10% happier if zoning codes allowed stores in residential neighborhoods.
