  1. They've got to get the price competing with parabolic airplane rides.
  2. So how long until this thing is flying daily? Pretty exciting that they are getting ready to carry people!
  3. Maybe you could use a binary black hole to accelerate a particle beam.
  4. Well, clearly there's some way to fuse pretty much all the elements.
  5. The most I'd want is a whole-universe scale slider - the ability to make the planets 10x bigger, 10x further away, and to give my rockets sqrt(10) as much delta-V.
  6. Yeah, I thought about that, but I think the luminosity figure takes that into account, since it basically says "here's how much power per unit area is coming out" no matter if you're in a diffuse cloud of hot gas or in contact with a hot stove pan. If you were to use the figure for that larger area, you'd be including a bunch of photons that actually weren't going to contact your body.
  7. Assuming your surface area is 1.7 m^2, your mass is 62 kg, your albedo is 0.4, and your specific heat is 3600 J kg-1 °K-1: The sun's luminosity is 3.828×1026 J m-2 s-1 over its entire area. Dividing out so we get only the luminosity from the area of a human, the power you are exposed to is 1.07e8 W. So, assuming this power is being emitted from all points and in all directions around the edge of the photosphere, Energy = Power * albedo * time In 1 microsecond you will absorb 42.7 J. Q = mcΔT Your change in temperature is .0002 degrees. In 1 millis
  8. In-flight Wi-Fi so you can scroll memes at 5G AND 5 gees.
  9. You'd see it. In 1 second it travels 14 km, which means in 1 millisecond it travels 14 m. In 1/100 second it travels 140 m. So, by 1/100 second before you'd be able to make out the object, and the whole encounter would last about 2/100 second. You'd probably only be able to watch half of that, but people can see things that happen that quickly, even if not react or understand.
  10. Sure, that sounds pretty reasonable. You could use stellar navigation or something, ping MRO or whatever...You can find your exact location using a clock and a table of preset information about star positions. Then you find Earth and figure out your best return window - a feat many KSP modders have already worked on. I think it's perfectly possible for a spacecraft to navigate all the way back home on its own - probably even simpler than what Perseverance did to set itself down in Jezero.
