Starship SN8

Those feet are actually pretty high tech in spite of their modest looks. Apparently their structure is such that they partially crumple on impact in a controlled fashion, absorbing the energy in the process, much like crumple zones in a car.

Didn’t realize that! Interesting. Found this info. about the struts and how they plan to evolve them.

”The prototype will also assuredly need several new landing legs after destroying at least two during its launch and landing debut. It’s worth pointing out that the leg damage visible above is almost certainly the result of an intentional design choice, ensuring that landings slightly rougher than expected transfer most of their stress into Starship’s legs instead of its hull. Given just how simple they appear, the current leg design likely makes them effectively disposable, allowing SpaceX to focus its effort on unsolved problems as a more refined and reusable leg design comes to fruition.

V1.1 legs will be ~60% longer. V2.0 legs will be much wider & taller — like Falcon, but capable of landing on unimproved surfaces & auto-leveling.”

And understand why there's a very different approach to all things nuclear these days compared to the 50s and 60s.

What happened then was pretty bad, but IMO the pendulum has swung way too far against nuclear. There hasn't been a single major nuclear incident in the US that caused loss of life, and there have been only two worldwide, one of which (Chernobyl) was so bad only because all nuclear safety design techniques (eg external confinement) were ignored, so when it blew, it blew straight into the atmosphere. With e.g. Fukushima that did not happen - the explosions were of vented hydrogen, so they only blew the roofs off the reactor buildings. Modern reactor designs can't even melt down the way Fukushima did, at all.

And even with all this, far fewer people died because of nuclear than from coal-derived emissions. Those are radioactive too, BTW. It's just that it's super easy to scare people with Chernobyl/Fukushima, whereas coal emissions are gradual and nobody gives a shit about them.

If anything millions die every year of coal and oil emissions because the fine dust particles that get released all the time take years from our lives. How many people do we know that die every year of nuclear power?
 
Looks like some things inside the base of the starship didn't hold up to the stress.
There's a strap fluttering around one of the engines.
Insulation is pulsing, tears, corners becoming unsecured. This is a insulation wrapping that doesn't seem to be secured very well and looks kind of wompas.

These concrete landing pads... it's like practicing your golf swing at the range on nice flat ground ..and then theres the actual tee box that is not perfect. Do they plan to test this thing landing on uneven ground, onto something dusty & rocky? How much debris is going to end up inside?

So this thing is supposed to send 100 people at a time into space as a amusement ride? Are the people going to float inside around the fuselage for 10 minutes...then strap back into thier seat.. get checked that your seatbelts on...and then land? Or are we just going to look out the window at the curvature of the earth? And these things are going to operate in similar style of a airport? These reusable rocks land, are reloaded with starships, and launch again... because it's so cheap and easy and a huge like of tourists ? Wait it's the new way to travel supersonic? Here to France in 45 minutes, weather launch window permitting. I dont buy it.

Recently they asked Elon where he sees humanity on 100yrs. He says I'll be happy if we still exist in 20 yr. Likely unlikely it's a asteroid heated for earth..but maybe.

Or is all this part of star force? Air supremacy at a space level. Massive payloads of space weapon and satellites with massive capabilities due to the size. Massive super satellites capable of acting like independent death stars. New space station US only. A new iron dome for supersonic missiles, lasers and space launched missiles.

No defense lasts forever. You only need to look at China's history with their walls to see that.

Why are the guys I put on ignore on all the covid threads suddenly piling into this one?

Because the universe has a perverse sense of humor.
 
just seemed like needs a bit more thrust on landing and they should be good to go.
from the images it seems quite obvious something is going wrong with the exhaust quite early at stopping the boosters one by one.

It appeared like the closest exhaust wasn't burning in the last several seconds, perhaps by control (as part of the rotation maneuver) or as a mistake or both.
 
Name a single benefit to you derived from astronomy that would be impacted by this satellite constellation.

You initially said "All the astronomy in the world can’t compare to the benefit of being able to communicate from anywhere in the world at gigabit speeds for $50/mo." You're now shifting the goalposts. Unix guy doesn't have to demonstrate that a benefit from astronomy would be impacted by the satellites, but rather that the benefits of the totality of astronomy throughout history is more valuable than this ability to communicate quickly and cheaply. How about the fact that if it wasn't for the work of Copernicus, Galileo, Kepler and Newton we'd have no idea that it's even possible to build satellites and put them in orbit? That network quite literally would not exist without astronomy.
 
Me and my buddy used to trade off solos over Blue Oyster Cult's Astronomy when we were in high school, so I guess one of the benefits of Astronomy is that it's a cool riff to solo over to develop your chops.

Nicely said...

In addition, I was commenting on the fact that we don't really need to communicate at gigabit speeds from anywhere in the world... It's nice, but most of the world's population can not afford $50/mo ;)

No, I’m not “shifting” anything. The kind of astronomy that’s actually not a waste of time and resources is not impacted by the satellites. The kind of astronomy that is impacted is better conducted through computational means (to reduce atmospheric effects) or from space directly. Nothing Copernicus et al did would be impacted in any way by these satellites if they were in orbit, which was my point.
 
I love watching satellites at night. Especially the ones that haul ass across the sky. I specifically look for them.
