I think the vibration we saw was mostly on the camera.

Jesus, that span is almost a quarter mile.

Half the marching band at my school are engineers. I had done plenty of ensemble music in high school, so I chose to go solo with my music and join some other types of groups instead.

He's planning to offload methane from Earth entirely. At least to a small degree.

The answer to that is yes. The engine nozzle is there to capture the kinetic energy from the exhaust, which in a chemical rocket combusts in the combustion chamber and then goes through the throat. Furthermore, if you really want to capture 100% of the energy, you need an infinitely long nozzle in space. Since the gains taper off with added length and eventually become a detriment, engineers calculate the bell length that gets the most energy while being light enough to accelerate as much as possible.

That's the one.

I'm in university studying to make rockets and spaceships. I help lead the liquid rocket team, which is currently not doing much.

The International Space Station is manned with a crew of seven and conducts over 200 microgravity experiments at once.

Not that it's so hard to land on Deimos anyway...the real trick is keeping from flying off again.

Would you really want your gateway to another world to be named after a god of dread, though?

Yes. I think the larger part of the insect farming industry right now is for animal feed, as humans aren't accustomed culturally yet to it. In any case I want to reduce consumption of beef...in my case by eating more insects.

Ooh, yes, that's a good idea too. I dunno, though, Starship is pretty big. They might be able to fit just one, like a spare tire in a car. I'm sure they'll at least have a small stack of extra heat tiles, in case they find some broken en route to Mars.

What's the mass of a Raptor engine? I'm sure they're planning to be able to carry spare engines for astronauts to replace on Mars if needed.

If they had the slightest inkling of rapid reusability and cheap production they'd be putting launch facilities in the Caribbean, NE and NW US. I'm a lot more distrustful of spaceplanes than of 'stick' rockets, there's something elegant about the mechanical stability of a teardrop capsule reentering the atmosphere that makes me confident I'll get to the ground safely. A plane has to be piloted and maneuvered all the way down, while a capsule does all the work for you so long as you pop the chutes before you hit the ground. Besides, Virgin doesn't even get to 100 km.

Yes, Proxima has a confirmed planet. This one is in perhaps a more exciting configuration with respect to its suns, though. Here's a diagram from the article: The two main suns orbit each other every 30 years, so I'm sure they're both fairly bright in the planet's sky. The fact that the planet's not in planar alignment with the other stars is intriguing and raises the question of how the system developed. There are probably planets which orbit all three suns in a system like this, but they would be so dim they'd be impossible to see with our telescopes.
