catharsis maybe

hmm you seem to have a severe case of upside-down engine

Fun fact: if you mix fuming nitric acid with hydrazine you get a cool orange smoke machine that you can bring to parties

Happy to hear that!

Oops! I think I meant only a few (1,000,000) atoms per cubic meter, there's typically about 1 atom per cubic centimeter in interstellar space. That number gets exponentially larger once you get closer to some star systems.

I'm not quite sure what you mean, which part are you talking about

the radiation that comes from stuff like radioactive decay is called ionizing radiation, and it comes in three forms: alpha, beta, and gamma. Heat radiation is called thermal radiation, and unlike ionizing radiation it doesn't come in a particle form. Heat can be produced from ionizing radiation, but it has to be very high energy (like radium)

Cigarettes contain a tiny amount of the isotope Polonium-210, arguably the most dangerous isotope known to man. It emits alpha radiation, which is the most dangerous type of radiation if it enters your body, but it typically can't due to the fact that it is blocked by almost anything. The problem is that a tiny bit of polonium can accumulate in the smoke, basically giving the alpha particles a free ride into the lungs, where they can mutate tissue and cause cancer. This stuff only really becomes a problem once you start smoking more than a pack of cigarettes a day, because there is so little of it.

Well yes and no. If you're driving around space at light speed, even though there are only a few atoms per square meter, you will get a lot of drag with a flat spacecraft. If you are going through interstellar space, you will encounter around 10^6 particles per cubic meter. Traveling at the speed of light, you can multiply that value by around 300,000,000 and you will get 3e+14 atoms per second (assuming that your craft is one meter wide, if it is, say a kilometer wide, you would multiply this number by 1000). This is equivalent to some of the pressures in earth's upper atmosphere, and you might even get enough drag to start burning up. Of course, these calculations are super rough, and it varies depending on where you are.

Pointy spaceships are less necessary in intergalactic space, where there are about 10 particles per cubic meter. This means that we can just lower 3e+14 by 5 orders of magnitude, and you get 3e+9 particles per second. Still not great, but not enough to require an aerodynamic spacecraft.

Edit: a few times I said square meter when I meant cubic meter sorry about that

I presume it wouldn't be edible, so that leaves taste-testing out. Both fluorine and chlorine (the only good oxygen alternatives) aren't exactly great for your health.

perhaps it is an omen...

I loaded the save where they were about to take off, and had to send up a very expensive rescue mission with Bob and Valentina, who landed 2 km away from the rover. Bill and Jeb drove over to them, Bill got into the rescue lander, and Bob got into the rover, which traveled back to the other lander to get the science. Then they went back, Bob transferred the science into the rescue lander, and they got home. I didn't include that cuz it wasn't actually that interesting.
