Ok, I take that back. I just watched that part again and he did get Musk to say that they were going to put Starlink v2 on Ship 24. Not much expansion on that, other than to talk about Pez dispensing and whether it might bind in zero g.

I guess we'll see what is the load out when this ever happens.

Part2:

Quote

Today we’re going up SpaceX's Orbital Launch Tower with the ultimate tour guide, Elon Musk. He’s going to walk us around the bottom, explain how they plan to catch the booster with the chopsticks and then we'll go up the elevator stopping at the quick disconnect and on the upper deck!

Some quotes/insights:

"At SpaceX, we specialize in converting impossible to late"

Starlink 2 is about 7m long and weighs 1.25t

The tower is supposedly the highest building south of San Antonia at 143m

This episode is kind of meh on technical details, except the Starlink Gen2 part, which is gigantic news.

He also said:
1. They already produced the first Gen2 satellite, and it's on site.
2. Gen2 satellite is close to an order of magnitude more capable than Gen1 (measured by "useful bits of data" per satellite)
3. User terminals will work with both Gen1 and Gen2 (already known but good to have this confirmed)

One takeaway I had - Making (terrestrial) life multi-planetary is just the first step. Eventually we need to go multi-stellar.

chopsticks · « **Reply #146 on:** 05/26/2022 04:46 pm »

I hate to complain (I mean the video is free to watch and everything) but I was hoping for a view of the launch mount from above. That angle never was shown. Perhaps SpaceX didn't want/allow that though.

Enjoyed the footage though, it was pretty cool to see the launch tower from the inside.

[Edit] Also, the view of the chopsticks from above was notably missing.

Yeah, this is the first time I've heard him mention "multi-stellar"

Is that why Gwynne Shotwell recently mentioned nuclear propulsion?

I dunno how Musk might feel about solar sails, or concepts like Zubrin's dipole drive.

Robotbeat · « **Reply #149 on:** 05/26/2022 06:22 pm »

Nothing really new about all that. Gwynne and Elon and others like Zubrin have mentioned the same things before. Gotta be multiplanetary so we can eventually be multistellar. Trade between Earth and Mars, and two way passenger travel, will be a forcing function to enable better and better propulsion, eventually enabling interstellar propulsion.

This drive to make life multi-planetary goes back way further than many realize. Elon is the latest in a string of people to bring it up, and I speculate that his interest in spaceflight might have lead him across the author below as well. For reference, here is one article titled "The Necessity of Space Travel: The Extraterrestrial Imperative" from 1981 by the late Dr. Kraft A. Ehricke. He was one of the colleagues of Wernher von Braun designing rockets in Germany and the USA.

Elon looks like he has a fairly fresh surgical scar on his right neck. I have that same scar; it's from an anterior discectomy to the cervical spine. The level of his looks like it would be either C7-T1 or C6-C7. If you do a fusion after the discectomy, recovery time is a couple of weeks taking it easy. If you do a total disc replacement (a prosthetic joint), recovery time is only a couple of days.

His scar is still pink and slightly raised. I'd guess that it happened some time in the last six months. Did anybody hear anything about this?

Robotbeat · « **Reply #152 on:** 05/26/2022 07:22 pm »

Yeah, you’re not the first to notice. He indeed had spinal surgery:

That's not a 2020 scar, that's a late 2021 or early 2022 scar

How do you know that? Could it not be a hypertrophic or mild keloid scar?

I have a bone spur sticking into my spinal cord too. It was found in and MRI in 2015. A second MRI a year later showed it had not grown. I was told to absolutely not have the surgery unless the problems got too bad to handle due to the high rate of failure of this surgery leading to paralysis. I wonder if he had worsening problems requiring the risk of surgery.

As a Canadian who spent years working in central Texas doing industrial control system and electrical design, I was horrified to see all the electrical work in the second video. Elon or the SpaceX team, if your reading this, PLEASE FOR THE LOVE OF GOD; stop letting the Texan electricians install ridged conduit everywhere... Its not all their fault, they don't know any different.. but PLEASE PLEASE, install some freaking cable tray and use TECK90 cabling. Its literally 10x faster to install, 1/2 the price, 10x easier to maintain and make changes/addtions too... I don't know why Texas is trapped in the 1960's using old and obsolete electrical methods, so please stop letting them build stage zero using 20th century techniques when the 21st century tools are light years better....

Sure, but this is cabling installed on a tower about to be exposed to >30 tonnes per second of high velocity superheated gas and several tens to hundreds of megawatts of radiant heating. Trunking is not exactly a bad idea.

Eventually, the sun will expand and vaporize the planets. That's a long way off. He probably means that the resources and space of the solar system won't accommodate humanity and/pr our descendants, biological or artificial. We'll need more room. Then there's always the allure of adventure and exploration. We'll be needing new, perhaps undreamt-of, technology to make interstellar travel practical.

Today we're getting a history and engineering lesson with Elon Musk about SpaceX's Raptor engine. We talk about some of the early design decisions and how the engine has evolved.
