That they will somehow lead space exploration including colonisation of places like Mars. It's covered in the video.

I watched the video. He isn't very good at making his point. Here's the thing. The only way SpaceX won't go to Mars is if the US government forbids it. Whether NASA participates or not is almost irrelevant. Not it sure it would even be better if NASA participated.

I remind me of something from the past...
ah yeah this: It! The Terror from Beyond Space

Via Twitter through NASAspaceflight

Inside the HLS prototype there are 5 bedrooms (ISS style, but horizontal), and a picture showing that you can fit 20 in one ring around the ship.
Being inside makes it SO clear that it's stupid big, and there will be no lack of space with any size crew.
They only have 2 floors so far:
One with very laid out life support, all clear to see (& in use).
The main one with the bedrooms, a storage area, 4 control seats, and a 40ft ceiling.

The HLS at Starbase didn't have a garage or airlock. (That may have changed, but I don't think so)
You can see the door in/out in pictures of it, up a flight of ~15 stairs on the outside.
Inside that door is the main room that's huge, and has bunks on one side and storage shelves with foam filled space bags on the other. The control seats, arranged like dragon (but just gaming chairs attached to boxes) are straight across from the door. 4 seats, with touch screens displaying Moon transfer, orbit, and landing maneuvers on them. (Similar to dragon docking simulator screens)

The center of the room has a ~8ft wide hole and a HUGE (4ft wide) ladder going down to the lower floor.
The floor is curved on the bottom as part of the dome for the pressure vessel. Big enough that you barely notice the curve in the area you can walk, but can see it curve up the sides under the life support equipment.
The life support looks like it is running fully, with the heat exchanger having a tubes that go out to the AC unit outside.

Sad to see that Lunar physics is not taken into consideration here, especially in what concerns gravity.

For example the vertical ladder will be a pain in the a** to use countless of time per day. On the moon, a muscular astronaut of 120kg will weight only 20. A tactical petite, only 10! To feel what it would be to step down and climb back that ladder,, try to put only 20 or 10kg at the gym on the bench and do a couple of minute of leg exercise... It's uncomfortable and even painful at the end.
We can see Lunar astronauts like Neil Amstrong repeatedly jumping from and on the LEM ladder to avoid the discomfort or gradually climbing it using the narrow spaced steps one at a time.
I would have though that, 50 years later, we could expect from their designers something that reflects a bit of back thinking on 50 years of blatant evidences.

Similarly, while in space, the absence of gravity would require a bracing surface for safety. The one side ladder doesn't look like the optimal solution here neither.

I do not congratulate those that came with this mess. And, frankly, that is not reassuring for the rest of the design. Hollywood Sci-Fi is cool but as a design inspiration, one should remember that it´s generally not made to be functional.

Note to the attentive reader:
Thinking about it, I might have some kind of complexion with ladders (Gripen, T-7 and now HLS!)

I don't know what you are talking about. There is only a ladder in the interior of the cabin between the two levels. There is an elevator for going down to the surface.

Wrong, there was no "discomfort". The step from the last ladder rung to the footpad was at a variable height due to the compression of the lander gear struts. Since the descent engine was switched off late (after landing and not at landing probe contact), the struts were compressed less and the rung was higher up. That is the reason for the jump. Also, the astronauts did not repeatedly jump on the ladder. They jumped off to get to the surface and jumped on to leave. They only did these once per EVA. Armstrong made an additional once jump once to test the ability to get back on the ladder before stepping on to the surface.

Hopping on the surface was found to be more efficient than walking given the limitations of the suit. This would not apply on the interior in shirt sleeve conditions.

no "bracing" is needed. A fireman's pole would suffice for weightlessness. the interior ladder serves the same purpose.

JSC internal communique:

Ever since astronauts started using Starship—-they started showing unusual psychological effects…one insisted that he identified as “Radio Riley” and wore a tunic with fins on the shoulders and a lightning bolt on the chest. When told he had to do another orbit, he said “that’s swell” even though he presented with no signs of edema.

What will bring a second trump term, with alliance with Elon Musk ?
Card blanch and blank Cheque for SpaceX, TESLA etc.

Hard time for FAA, FCC, USFWS and everyone who stands in way of Elon Musk plans

That would be wrong on both accounts. The gov't agencies just following the law.
No blank check, Congress controls the money,
 
Did everyone else know this because I sure didn’t?

Vance is a protege of Peter Thiel, who was the first outside money into SpaceX and was a member, like Musk, of the Paypal group. Vance as VP will of course be head of the Space Council.

Also whoever Musk ‘suggests’ Trump to pick will likely be the next NASA Administrator.

The Space Bucket has just put out a video about SpaceX's upcoming IFT-6 test-flight:


Just yesterday, SpaceX announced that the next Starship Flight is only about 11 days away, scheduled to liftoff on November 18th. In addition, they released a host of new information related to the flight profile and general launch plan.
Click to expand...
This includes interesting details like a scheduled launch at 4 P.M. CT as opposed to much earlier in the morning in support of a daytime ship landing among other details.

"Starship is now more than twice as powerful as the Saturn V Moon rocket and, in a year or so, it will be three times as powerful at 10,000 metric tons of thrust."

It's not about size or thrust, but what you can do with it.

Saturn V brought astronauts in an Apollo capsule to the moon, plus a moon lander, plus a moon rover, and brought the astronauts back with moon rocks, and that all in just one launch.

Starship can't do that as it is just a two-stage rocket.
To get itself to the moon to act as a moonlander it requires some ten refuellings in LEO.
On top of that another rocket has to bring the astronauts to the moon and back.

I hope that SpaceX will soon realise that and come up with a three-stage design that can reach the moon in one launch.
 
I don´t know if reaching the moon is better with a third stage and an anemic payload for the needs we have today (from exploration to exploitation) or, as SpaceX plans, with on orbit refueling.

Decades ago, strategy thinkers were envisioning giant escort planes for long range bombers, or even carrier airplanes piggy packing awkwardly (and unsafely) escort fighters. Then came air to air refueling and tiny fighters were seen deployed in every corner of the globe within the snap of fingers...

Let´s see what comes off their plan first.

Does NASA really need a moon lander as big and heavy as Starship?

In the mean time I read Musk's complete tweet on X.
He says that: "This enables cost per ton to orbital space to be ~10,000% lower than Saturn V"
Somebody should explain to him that something can never be more than 100 % lower than something else.
Hopefully there are no such numerical errors in the design calculations of Starship.

Musk 10,000 % lower.jpg

wrong. Musk doesn't care.
