Only if the ship was not owned by the launch company, or was but was not evacuated before launch.

Thanks for the video. If that ship was not part of the launch facility and previously evacuated, then that crash so close to it seems like a very risky launch program. Even if the rocket had been blown up at engine shutoff, the ship would have been in danger of falling debris..

I would not agree that the "big bang" is an observed fact. The observed recession of the other objects in the universe is a "fact" so far as we can tell (although there are other attempts to explain the observed red shifts). But, extrapolation of that observed expansion backward in time to a...

Interesting that it did not get intentionally blown apart like U.S. launches do when they fail. Perhaps it did not get outside of its predesignated flight path before its engines were turned off, so it was allowed to just fall? Or doesn't the European/Norwegian/German bureaucracy require...

While not trying to minimize the importance of the observed trend, I think that it is important to be careful of the context. Statements about the ice level being at "an all-time low" and "the lowest Arctic winter sea ice levels have ever been" are not actually true. They are only the lowest...

Ken, The SpaceX Dragon capsule is the alternative, and has many missions already accomplished. The SpaceX vehicle that has not been fully developed, yet, is the much larger SuperHeavy + StarShip, which has had successful launches, and even successful soft "landings" in water plus successful...

Hoping for a non-crewed flight before NASA takes the chance of repeating the mess that occurred in 2024. There is a reason for requiring uncrewed certification flights - let's not forget the reason. Last time was only a costly and inconvenient embarrassment - worse things might happen.

This article states: "If a matter and antimatter particle pair is created with equal and opposite energy within a limited space, then the total energy of that space is still zero." So, that seems to imply that antimatter has negative energy. But, we don't model energies below zero. And, we...

COLGeek, sorry to hear you were on the receiving end of a bullet transfer trajectory. As you probably experienced, along with Dimorphos, the effects are related more to the energy transfer than just the momentum transfer. Which makes sense, considering that the shooter always absorbs more...

You could get a reasonable approximation of it by hanging in a harness with your feet off the ground when you fire. Paratroopers can do that. But, you need a safe place to try it, so that bullets don't go anywhere they can cause trouble, because it is hard to aim well when your body is not...

It would feel about the same as experienced on Earth - you body rapidly absorbs the amount of momentum equal to that of the bullet and the gas that exits the muzzle. Except, if you are not backed up by a bulkhead or something else fixed solidly to the station, it will get all of you moving in...

This story seems to have substantial infusion of click-bait. The jets from the poles of black holes are usually going perpendicular to their galactic planes defined by the orbits of the stars in the galaxy. So, they are not "pointed at" the planets in the galaxy. The article acts like that...

These stories about black holes always strike me as inconsistent with stories about the BBT "beginning" of our universe. The whole picture would make a lot more sense if the material inside a black hole does not really get compressed to a zero dimension, and the universe oscillates density...

Please note that the UN Charter, the Ten Commandments, and many other written documents have failed to achieve their stated objectives. Laws, regulations, customs, taboos, etc. are all regularly broken. There is also the problem that those given enough power to actually enforce such things...
