Babylon 5 taught me the answer to this!

When a craft explodes it has an atmosphere, or the components necessary to mix and create said atmosphere, in the craft. At the very least mixed around the pilot in some capacity.

Different species with different atmospheres may have different coloured explosions. Example, for us it'd be yellow/orange/red. The typical colours we associate with fire. An enemy might have green explosions, or blue.

I've thought about this as well. I don't think we really know what exactly an oxygen explosion would look like in space. Presumably, it would at least flare up until it disperses in a few seconds.

Might depend on pressure of the vessel, flow rate of the oxygen, etc?

There are so many things wrong with most space movies, someone could write a book about the drivel one sees onscreen. For example, most space movies have magic gravity that does not exist in space and their ships magically have it. They also often bank their ships flying in space, as if they were using wings in an atmosphere. They ignore the reality of distances and the impossibility of faster than light travel, the fact that hitting a spec of dust at anything near light speed would obliterate the spacecraft, etc.

Most "science fiction" movies about space are more properly thought of as fantasy films rather than SCIENCE fiction, because they have little to do with science.

Taxpayer funding of such endeavors is not the hill you want to die on. The entire miniature electronic world we live in now is completely due to the moonshot. And about 36 people are monetizing it. The taxpayer has been fucked over time and time again. Case in point The current situation with Moderno grossing over 36 billion on the vaccine +10,000,000,000 paid by the taxpayer upfront and paying a $400 million fine on government research that is essential to their product. It's morally bankrupt and any civilized society would either criminalize or under no circumstances, accept such behavior

What makes you say that? Pretty much all research and experimentation on human life systems in space has come from ISS, not to mention that the only vehicles that have undergone enough development to be human rated exist purely because the ISS gave them a reason to.

People can talk about space tourism all they want but the real dollars come from government contracts— and the government has spent a lot of money to build and maintain the ISS, that money isn’t wasted— it was paid to the contractors and industries that have now matured to the point of being able to make their own decisions about investment in space (see: satellite internet constellations, and SpaceX starship). We wouldn’t have a mature private space industry or nearly as much knowledge about living and working in space as we do now without the ISS.
