Do you believe that taking an extremely long time to do something makes it safer.. ? like 5 years of development is safer than 2 years? Were NASA’s decisions to pivot in weeks for Gemini VI/VII or months for Apollo 8 unsafe, or were they historic examples of competence that kept America in the space race?
Much of the Reddit noise seems to come from people looking for reasons to take out their affinity for specific hardware, political differences, or personality conflicts on America’s lunar program.
It has been long enough. We have been working for decades on America’s return to the Moon. We finally have the space policy, political alignment, resources, industry, and talent to accomplish this goal safely after a very long wait.
We have two landers, and we will preserve the option to use either for as long as possible while turning every knob available to improve the probability of success.
That means different vehicle configurations will remain on the table for Artemis IV until they are no longer viable. And for the most committed EUS advocates, it was never going to be an option within the timelines required. The OIG report already covered that. Even getting core stage production to an annual rate is a challenge.
The decision to consider Centaur, stretched Centaur, and other upper-stage options over EUS was made by nonpolitical NASA leadership assessing cost, technical work ahead within timelines. I know this is disappointing to some hardware fans, but the idea that it is all a cover for lander availability does not hold up. NASA would have wanted an Artemis III test before an Artemis IV landing regardless, and an extended-mission Centaur would offer far more value for a lunar base and other applications than EUS. That is the reality.
We are an energized and dynamic NASA and we are not just waiting around for others to deliver. It is NASA’s responsibility to drive the outcomes people have been waiting for, and that is exactly what we intend to do.
We are targeting October 23 for the next Artemis update, though that date is not final as folks return from IAC.

Since your profile indicates you are a former NASA, I thought I would flag a few points:
1. I personally pay for all costs associated with the fleet of F-5 aircraft, be that airshows, NFL flyovers, or NASA workforce incentive flights. The rest of the NASA fleet, including F-15s, F/A-18s, and T-38s, requires currency flights to maintain pilot proficiency. Would you prefer they do that over the desert where no one can see them?
2. Obviously, the first A in NASA is Aeronautics, and throughout our history we have taken NASA X-planes to airshows. In fact, a lot of my strategy at NASA draws upon our proud history. We took the X-31 all the way to the Paris Air Show in 1995, the SR-71 was featured at the Edwards Air Show and Oshkosh in 1997, and the X-29 flew at the Dayton and Oshkosh airshows in 1990. It is part of our history, and do you know why? Because inspiring the next generation of engineers, scientists, researchers, pilots, and astronauts is part of what we do. It always has been.
3. It is also our nation’s 250th birthday and the year we returned NASA astronauts to the lunar environment. We are returning to the Moon, building a Moon base, and this is a great time to get out, engage with the public, and tell the NASA story.

Somewhere on that beach is a future pilot, engineer or astronaut. That’s why we fly.
An incredible weekend over Huntington Beach with our @NASA team at @PacificAirshow. America has big missions ahead, and we’re going to need the next generation ready to take them on.

Starship transiting the Sun this morning during Flight 14 — prior to this morning's mission, this has never been captured before with the world's largest and most powerful rocket.
I’ve ached over this shot for years, mainly for two reasons: what does methane exhaust look like silhouetted against the Sun, and how violent are the acoustic energy waves from 33 Raptor engines on the Super Heavy booster?
Well...now we have an answer.

SpaceX has released a new blog post about Starship’s 14th flight today.
“During Starship’s ascent burn, a single Raptor vacuum engine shut down early. Starship still achieved its planned, passively safe suborbital trajectory by burning its remaining five engines for longer than planned to compensate for the loss of thrust.
After entering its suborbital trajectory, the flight control team assessed Starship’s systems and determined the three sea-level Raptors engines needed for subsequent burns were healthy and gave a “go” for orbital operations. Starship then reignited a single Raptor sea-level engine to perform an orbit insertion burn and entered into orbit around Earth for the first time.
After a brief coast, Starship then deployed all 26 Starlink V3 satellites. Contact was made soon after with every satellite over laser links, ground stations, and Starlink user terminals. The satellites will now conduct on-orbit checkouts and raise their orbits before they begin serving customers.
Following payload deploy, Starship entered into a coast phase around Earth. Out of an abundance of caution given the engine issue experienced during ascent, the flight control team decided to limit the duration spent on orbit and proceeded with deorbiting Starship to a splashdown location in the northern Pacific Ocean. This area was one of two pre-coordinated landing zones identified before launch that was cleared of sea and air traffic.
Starship then relit a single Raptor sea-level engine and performed its first ever deorbit burn. That maneuver successfully brought the vehicle out of orbit and sent Starship through atmospheric reentry and descent to the intended splashdown point.
The first orbital Starship flight concluded with the vehicle relighting all three Raptor sea-level engines in a landing burn and flip maneuver before splashing down on target in the Pacific Ocean.”

BOOM!
I happened to be shooting this galaxy when a star decided to explode. Pretty lucky!
You can see it appear close to the galactic core. I’ll be shooting it every night for a while to watch it change brightness!
This is comparing photos captured 10 days ago vs 5 min ago.

I’m with Maye! Elon is extraordinary and (I know you’ve heard this) I love working for him (coming up on my 24th year doing so). I don’t love being around miserable people. Elon isn’t one of them.
This is weird @THR “Someone who worked closely with Elon told me, ‘He’s the most miserable man I’ve ever met.’ I haven’t seen him miserable, but that’s just me. His mom.

Callaway CEO Chip Brewer is an idiot. They’ve now done multiple statements about this ad, complete with a pro DEI rant AND they ended their relationship with GoodGood golf brand. You’d think the ad included a husband beating his wife. It does not. The ad was a satire of Obsession where the guy is obsessed with his driver and tackles a woman who reaches for it. Remember Betty White getting tackled in a snickers ad? Did anyone think it was promoting elder abuse? No because we’re not mentally ill. Does Chip know his demographic for Callaway? It includes a LOT of people who OPPOSE DEI and idiotic groveling to woke mobs. If those people realize he’s doing this, this could get bad for Callaway! Oh and the worst thing about the ad was bad acting. That’s it. It was very obviously a joke.

Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!
SpaceX makes sci-fi real.
Introducing Starbase, Louisiana – a high-cadence launch site that will enable Starship to open a pathway to the stars for humanity.
Thank you to @LAGovJeffLandry and the great people of Louisiana for all of their support as we work together on this audacious project → spacex.com/sites/starbase-la

I believe the urge to “hit from the top” is one of the most destructive impulses in golf.
It’s incredibly tempting to pull the club down hard from the top because it feels powerful. But most of that effort is wasted energy—and it can destroy your sequence.
I teach my students to do the opposite: let the club fall in transition.
Wait. Be patient. Let the club settle before you accelerate. The real speed comes later, where it actually matters.
You must learn to wait!
My next 12-week Performance Academy begins in early September. If you’re ready to make lasting changes and start playing the best golf of your life, email me at [email protected].

Physicists may have found the origin of gravity. And that would finally explain why gravity is different from the other forces of nature.

Elon: "I don't want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn't mean we won't make improvement, but we do not see any technical obstacles to achieving rapid reusability at this point."
