Looking forward to them having a MMU of their own and actually letting astronauts use it for a change.
Contrary to some--I don't look at this spacewalk as a "stunt."
Nobody drowned in this suit, after all.

I'd love to see SpaceX successfully carry out what the Gemini 9A astronauts failed to do in their EVA:
USAF Astronaut Maneuvering Unit
The AMU.
The United States Air Force (USAF) Astronaut Maneuvering Unit (AMU) was designed by the U.S. Air Force, which was planning to use the Gemini spacecraft as part of the Manned Orbiting Laboratory (MOL). The AMU was a backpack using hydrogen peroxide as the fuel. The total delta-v capability of the AMU was about 250 feet per second (76.2 meters per second), roughly three times that of the MMU. The astronaut would strap on the AMU like a backpack, and maneuver around using two hand controllers like that of the later MMU. Because of the fuel, which came out as a hot gas, the astronaut's suit had to be modified with the addition of woven metal "pants" made of Chromel-R metal cloth. The AMU was carried aboard the Gemini 9 mission, but was not tested because the astronaut, Eugene Cernan, had difficulty maneuvering from the Gemini cabin to the AMU storage place, at the back of the spacecraft, and overheated, causing his helmet faceplate to fog up. The AMU was also meant to be launched and flown on-board Gemini 12, and to fly untethered from the Gemini spacecraft, but was scrubbed two months before the mission.[2] NASA chief astronaut Deke Slayton later speculated in his autobiography that the AMU may have been developed for the MOL program because the Air Force "thought they might have the chance to inspect somebody else's satellites."[3]

I wonder if he’s ever heard of the term your own worst enemy. Hopefully some will get what I mean without derailing the thread.

Technically she is in free fall since the ship is still in orbit around the planet. You only get zero g in deep space.

Spacecraft NOT ship.
There is no such thing as zero-gravity, gravity is everywhere, freefall or weightless are the accurate descriptors.

Exactly Nmaude, gravity exists throughout the entire universe. I do not know where the term zero-gravity came from in the first place, was it in the early parts of the space race?
Very likely from ill-informed, and poorly educated, in science reporters.

That's what I thought NMaude.
Mr. Musk: The best way to preserve life is to build a large number of orbital cities with standard rotational gravity, oxygen and nitrogen atmosphere, high radiation protection, and the ability to change position at high delta-v levels to dodge the worst of solar storms by hiding behind the planet they orbit. It would be convenient for these cities to preserve DNA banks of all terrestrial species, even if in the future it would be enough to store the numerical keys to be able to recreate them in the laboratory. If you want to contribute to the continuity of life on Earth, the best investment would be to dedicate resources to research into new forms of radiation protection... our worst enemy in space.

I remember watching a Bible movie about the Great Flood in which the wicked who laughed at Noah later tried to climb into the ark when the waters were up to their necks. Can you imagine the lawyers who now make a living by hindering any project by trying to get on the last rocket???
How many regulations would have to be violated to hold Woodstock-69 again?
When the asteroid arrives, all the regulations will remain in the offices and the paper burns at 453ºF.

We are back on Earth and look forward to sharing the results and our experiences with all of you. The scientists and doctors rightfully own all of our time for the next few days, but I did want to share a few thoughts as I reflect on our mission and what we set out to accomplish.
We deeply care about the world we live in today and making it better. That’s why we wear the @Stjude patch on our flight suit and why we dedicate so much time to raising funds and awareness for their vital work. It’s why we partnered with @ElSistemaUSA to show how the beauty of music can bring people together all over the world. It is why we’ve brought Starlinks to various corners of the world to help connect people and provide access to information—building blocks for solving many of the world’s challenges.
As we work to address today’s problems, we must also look to the future we want our children to grow up in. As a crew, we have always believed in humanity's destiny among the stars—a belief that’s only been reinforced by our recent journey. We had very specific mission objectives, some familiar from the past, but in many ways, they were different today.
We took our spaceship farther than any human has gone since the last Apollo mission over 50 years ago, and along the way, two of our crewmates became the women who have journeyed farthest from this planet. Now, if we have been there before, why is it significant? The better question might be: Why haven’t we gone back? It’s not easy to travel that far into space. It requires immense energy to send a human-rated spaceship to such a height, and if a rapid deorbit is required, dissipating that energy is not easy. The environment is harsh, with increased radiation, more micrometeoroid debris, and no nearby safe havens in case of trouble. We went there to study the radiation environment, gather data on its impact on systems and human health, and to explore areas we know less about, where we can learn new problem-solving methods that will help in future missions. Records are meant to be broken, and we are so excited for @Artemis to take us ALL to even greater heights.
We conducted an EVA (spacewalk) and tested a new-generation spacesuit. There have been over 300 spacewalks in the 60-year history of human spaceflight, the most famous being those of the Apollo moonwalkers. By any standard, what we did was basic in comparison. The difference is that those spacewalks were conducted by government agencies—NASA, ESA, Russian Cosmonauts, Chinese Taikonauts—with the full backing of their nations' resources. In the future, tens of thousands of people will be working in space on multiple space stations, lunar bases, and Mars outposts and not all of them will be government astronauts. Space belongs to everyone, and it’s essential that both commercial and government efforts work together to make that future a reality. It is critical for the commercial industry to have the tools and experience for spacewalk operations and the suit we tested is just the first step in that journey. By opening up new frontiers, we’re building a future for all of humanity, not just a select few. Along the way, we’ve learned a lot about the technical disciplines related to EVA operations, which will only accelerate the iterative design process that @SpaceX executes so masterfully. I will personally treasure the experience my crew and I shared, but I am most excited about future generations of the suit and where they might be used someday.
We tested new laser-based Starlink communications, using it primarily as an alternative communication pathway to Mission Control, but also to put together a very special moment: my crewmate @Gillis_SarahE playing the violin in space. This wasn’t about being first at something, but about showing the world a different perspective through the power of music. To maybe think a bit less about the differences that dominate daily discourse and a bit more about our shared humanity and what we can achieve through some measure of unity.
Beyond what we hope to learn from these technical objectives or the ~40 science and research experiments, there is always a fundamental requirement of any space mission: to cast the widest possible inspirational message. There were many firsts on our mission, but just as important were the things that were simply different from what people are used to seeing. These differences can spark all sorts of creative thinking and maybe inspire the next generation to dream about what they can accomplish among the stars. Because if we’re going to realize humanity’s destiny to reach out and unlock the mysteries of the universe, we are going to need a lot of inspired dreamers to join this grand endeavor.
I want to close by thanking everyone who worked so hard to make this mission safe and successful. Of course, that starts with the 14,000+ @SpaceX employees, from top leadership like @elonmusk, @Gwynne_Shotwell, @jjfactorykat ,@skeech412 and @TurkeyBeaver to the SpaceX technicians inspecting our booster before flight. Special thanks to all the @PolarisProgram team that supported us throughout this journey over the last 2.5 years of training to the 24x7 on-orbit operations. I also want to thank @NASA for their foresight in creating the commercial crew program, which breathes life into initiatives like @PolarisProgram ..not to mention NASA's direct mission support and EVA suit testing. Thanks to the weather teams, recovery teams (including the @USCG), all the researchers, and everyone of our supporters that cheered us on and dreams of a brighter future. With our deepest appreciation and gratitude, THANK YOU!

The FH to be used for Europa Clipper isn’t a standard version as it features hardware modifications to squeeze additional performance from the booster, allowing more complete burning of the propellant, and also use of TDRS for data transmission. No information given as this is proprietary. This has allowed the launch window to be extended to the 6th November. It will also be the fastest FH second stage to date.

The Space Bucket has a new video out concerning the FAA recent fine levied against SpaceX:

A good question but given how Boeing is in the doghouse with several US federal agencies and rather publicly for example with the 737MAX and the Starliner I'd say that the FAA is looking to make an example.

So they picked SpaceX instead of Boeing? Any guesses why? (It's a rhetorical question, obviously.)

The fines are questionable just because of the timing. Happened a year ago and they just now are deciding to fine them? No-one heard a word of fuss or of an investigation until a year later the fines were announced?
And SpaceX has filed a lawsuit against the FAA over this very fine and issue.

Couldn't possibly be related to the recent Congressional grilling of the FAA over their glacial approval process for spaceflight permits, with the experiences of SpaceX (not in attendance) in particular being brought up (concerns about the FAA holding approvals for months before requiring minuscule changes in the application followed by more months of delay).
No, not possible at all.

FAA wants to fine SpaceX $633,000 for alleged safety violations during 2 Florida launches
SpaceX faces $633,000 in fines for alleged safety violations during two Florida launches last year. The Federal Aviation Administration said Tuesday it's proposing the civil penalties because of the company's alleged failure to follow licensing requirements.

Oh please don't throw me in the briar patch...
Hard on the heels of Chevron'...I half suspect the individual behind this fine at the FAA is secretly a Musk fan...hoping he'd win in court.
Were I the FAA, I would not want to look so petty.

Yes that’s correct. I suspect it may not even be carrying landing legs to reduce mass and that they are not needed.
If it's in full expendable configuration then it definitely won't be fitted with them along with the grid-fins and associated servo-motors and associated hardware.

FAA delays Starship. FAA fines over Falcon 9. Yeah, this administration is tots above board. What did they do to Boeing for Starliner? Oh yeah, nothing. Wouldn't blame SpaceX at all if they said, "Dragon is not available to save your astronauts on ISS due to internal safety review".
