I don't find screens on windows tacky & they are nice in summer to avoid all kinds of flying insects getting in when the windows are open in the evening. But they do make it harder to exchange inside and outside air, as they increa

IIRC all sources are tracked at manufacture and it migh also be possible to try to match the isotope ration to the original source material ? Not to mention the whole "spraying deadly radiation all over the place" that can be dete

Yeah, just spin it - like Oneil Island 3 or similar (Stanfort Torus, etc.): https://en.wikipedia.org/wiki/O%27Neill_cylinder That's a 1975 design using quite conservative 1950s tech - lots of bulk steel and alumin

I still don't get how people are so fixed on planets - is it because of Star Trek or Star Wars or in general being more consumable for the average human ? Even just the Solar system has resources and energy to build artificial habitats

Rather, this should be opt-in from the start with serious disclaimers what it does and what it has access to.

Both Airbus and Arianespace are quite distributed across the EU. While this seems to have worked fine for Airbus, it does not seem to work that well for space launchers under the Ariannespace umbrella - though some bits of the Ariane 6 &amp

A mass driver would run off a capacitor bank most likely - can't you just charge that by a solar array ? Unless you really need to send huge amounts, this should be much less hassle than lugging a nuclear reactor around. And for near-E

I don't think dumping heat into the ground would work for any meaningful amount of time - both on Earth and on Mars the dirt and rock are not a very good conductor of heat, so you would quickly heat up your local "heat island&quo

I think it can - I think it might encode something in the beam, use a slightly different wavelength or even just pulse the laser so that the returns don't overlap if timed right.

Why not both ? ;-)

In Czech Republic upgraded our infra and stopped using Russian gas and oil. Might have something to do with Russia orchestrated terrorist attack agains Czech munition warehouses that killed two people in 2014[0]. Or the Soviet invasion of C

The reasonable countries, such as for example Czech Republic stopped using Russian gas and now also oil while the ones corrupted by Russian interests did not & could not be expected to until either their government realigns with the res

There is Sailfish os Ubuntu Touch, you can run Fedora and Debian rebuilds on phones. I think it is finally getting there & all this Google and Apple bullshit will hopefully make it move faster and be more attractive to people. :)

Is it really safer on a phone ? Don't banking apps reject latest community Androids builds with all the CVE fixes or Graphene OS yet work totally fine on years old, full of vulnerabilities yet signed official Android ROMs ?

Yeah - while real space development will use 99% of local resources eventually, the cheaper we can get stuff to LEO the quicker we can get things going. Not to mention lifting any complex stuff & humans, that which simply not be availab

Sure, but also much less efficient per unit of mass than regular cooling using the atmosphere or hydrosphere here on Earth.

Actually existing Starlink satellites regularly bu p into each other when lobbed in benches by the Falcon 9. They are built to tolerate that, resulting in much better launch volume and weight utilization (sats are stacked on top of each oth

AFAIK there is a bunch of Chinese startups pitching some fully reusable designs and/or ready to clone something that works. There is already some Falcon 9 like first stage reusable booster prototypes in development.

I would actually argue that Apollo and the space race damaged reusable launcher projects more than the Space Shuttle. Before the mad scramble to the Moon there were many interesting infrastructure projects and incremental manned mission pla

Testing to destruction is used quite often to discover the final limits of materials and machines.

I think there was just one unexpected engine out on the booster during launch. Starship engines worked without any issues on this flight AFAIK. :)

Starhopper is still there, on a parking lot next to the launch site. :) https://starship-spacex.fandom.com/wiki/Starhopper

I would say they nailed it based on achieving all the objectives they stated before the launch.

Isn't AOSP developed behind closed doors, with infrequent code drops & zero community participation ? Good luck building anything on top of that & keeping it in sync long term.

This is definotely on purpose & quite important for the upcomming starship catching for rapid reusability. :)

Maybe just some part of the construction (possibly even just the strinngers or simply some nook or cranny that is fully eclosed) got presurized or was pressurized for the whole time by just air that could not escape. That would be fine for

I guess this is where checksumms and digital signatures come in to prevent unauthorized stuff like this ?
