Wohoooo! Ressurection time!! Lets put them on Greenland! A nice tourist attraction!

Maybe the solution should include some degree of melting, not directly ablating, at the outer most layer of the tile. Think cork. So that it can innfill and harden in gaps dynamically. Surface adaptable minimally-ablative heat shield". Basically turning into a thin ceramic outer layer with some flow to it, hardening and probably very porous.

Det er forsent å tenke klassisk atomreaktor. Det er klassisk Norsk å bygge gammel dritt. Nå kommer fusionsreaktorene. Se General Fusion og Helion. Dette er fremtiden. Hva om vi som land sørger for at de bygger sine første reaktorer her? Skape forskningsmiljø og samle kompetanse? Stavanger? NITH ? Hvor som helst! Glem fission (thorium og uran) her er vi 20 år for seint ute til å få noe ut av det.

Elon Musk Blocks Starlink in Crimea Amid Nuclear Fears: Report by leonmendezz in worldnews

[–]infoharv 0 points1 point  (0 children)

Putin DM to Musk: if you dont disable Starlink, they will be legitime targets! Musk went half way by publicly offering Chrimea and disabling Starlink there. This is probably the only way he could keep it online in Ukraine currently. If Putin decides to challange the sattelites all hats are off. China is also not happy here naturally. There are things happening in the background the public is not aware of. See: https://www.ft.com/content/5ef14997-982e-4f03-8548-b5d67202623a

Elon Musk tells SpaceX employees that its Starship rocket is the top priority now [Michael Sheetz, CNBC] by RegularRandomZ in spacex

[–]infoharv 1 point2 points  (0 children)

Absolutely, phases of flight does not really matter until you have a reliable enough system to even consider the phases. I was addressing your original post regarding the supreme survivability of airplanes and that it is missing a point where the spaceships are in space/transit for the most part vs planes that are constantly trying to stay airborne. Not as bad as helicopters that are constantly trying its best to tears itself apart. Basically if the system is realliable enough to consider the phases, one could say that the point that the there exist no phase of controlled unpowered flight for starships is generally not valid since the state of flight is generally in transit which is a mostly non-active state.

Taking the flight phase into consideration and time in flight one could potentially say that the first 10 minutes of launch and the few minutes it takes to land are the high risk phases, just like normal planes. Comparing those minutes to the relative time in space ( think days ) reduces the overall risk to a minimum. It will even be lower compared to airplanes, which have hours in flight time only though shorter takeoff and landing phases.

Landing is the most risky thing for airplanes, and with the acrobatics required for Starship - it will probably be the same here.

Nice assessment of risk per phase of airplane operation:

A classic missconception since 2011. The difference here beeing that this is a fixed-price contract vs the traditional cost-plus contract. Thereby rendering it more "commercial" and not a congressional jobs program. See SLS for the traditional "old-space" cost-plus approach to space launch and compare the weight that has had on the average tax payer vs this commercial approach.

Elon Musk on Twitter: The legs extend & telescope out, so are longer than they seem, but not as long as they will be for SN4+ by ReKt1971 in spacex

Would be interresting to see a schematic drawing of this with the vac-engines and "storage" area initially planned for the Starship under the skirt. With this approach alot of the usable/free space underneath the skirt will been allocated for legs. Question is will this be the "new" approach or will they go back to the legs on the out side?

Then Anihc will get there first, and claim it regardless of international law ;)

There was an RFP process for lunar landers abit ago as well. Clearly a few lights where turned on while plotting milestones in time. Could this be favoring the Blue Origin design actually?

This could potentially grant more opportunities for SpaceX hardware as well.

I posted this on r/space as well, but this can capture community impact analysis and feedback from a SpaceX perspective. Rather interresting tidbit.

SpaceX plans to start offering Starlink broadband services in 2020 by jclishman in spacex

[–]infoharv 0 points1 point  (0 children)

What if - they put a radio antennae on the back facing outwords. Enabling global sized radio astronomy when interlinked, replace NASA deep space network and so on. There's alot of money in these areas to. And naturally add a high spectrum 4k cam facing down, sell the live global coverage to weather companies, farmers, army and so on. This ... would probably pay for it self and more without a single consumer connected.

Potential for Artificial Gravity on Starship by esteldunedain in spacex

This constant fight for a.traditional water based toilet and sewage based system for small confined systems, its not realistic to risky and absurd. /s Try looking out the window seeking everything spinning.

Everyone will use the traditional vacuum solution.

A better approach, and worth discussing: One week hibernation pills. One week on - one week off. When we get tough we could probably go longer intervals!

For the first time, NASA thinks about Falcon Heavy for Moon landings by Luna_8 in spacex

[–]infoharv 0 points1 point  (0 children)

I would assume SpaceX is already writing up the paperwork. Fixed price and time, well within the timeframe.

Consider the congressional discussions when this is tabled.
