The steel in your sink is expected to carry far less load than the starship. For sinks you may be able to get away with using as cast steel, but I would expect that they do at least some work hardening, not to mention they are probably using a special grade of steel -
The president of france has requested that ESA assemble a "high-level advisory group" composed primarily of "non space experts" to "look at various aspects of society" and "come up with more specific European targets and ambitions for manned space travel". In other words, he wants to establish a committee to develop future manned spaceflight related committees. https://spacenews.com/esa-to-set-up-committee-to-study-human-space-exploration-options/

Kepler is heliocentric and deactivated, so that probably won't happen, and Hubble needs the robotic arm to keep the vehicles together -
New planet discovered in proxima centuri system
insert_name replied to insert_name's topic in Science & Spaceflight
Surprisingly, the equilibrium temperature assuming earthlike regolith is only 87c, hot enough to cook with, but a decent cooling system should keep you nice and raw, though a thick atmosphere could make things worse -

The offending cruise ship from the other day has been identified as Royal Caribbean's Harmony of the Seas, definitely should have been capable of reading a NOTMAR, coasties are investigating. https://www.businessinsider.com/spacex-rocket-launch-royal-caribbean-cruise-ship-coast-guard-investigation-2022-2 -

Tldr the warp drive paper was from the same guy as the EM drive, and all he definitely proved was that the potential curves between his apparatus and the warp drive are a similar shape. https://bigthink.com/starts-with-a-bang/no-warp-bubble/

Is that a fact, I somehow doubt that setting off a bunch of nukes is less likely to go wrong than a saltwater reactor that shoots its fuel out the back end? Considering how little data we have regarding the operation of these types of vehicles I'm not not sure anyone can say for certain which is more reliable -
Orbital Reef / Starlab / Noname Northrop Grumman Station
insert_name replied to Shpaget's topic in Science & Spaceflight
Scott Manley pointed out the dragon on the bottom of the northrop one appears to have the end door still closed, which means it cant be docked, and is just floating below the station -
I seriously doubt that there is any material that is capable of contracting at hypersonic speeds while remaining intact. Furthermore, steps must be taken to stop the "bowstring" from shooting out with the projectile and then getting pulled back into the "bow", because hypersonic collisions are not something you want to have happen to your launch infrastructure.
