    Question How do you estimate the weight of a vessel?

    I still have a problem dV = Isp * ln (Me/Mt) dV = Delta V (30,000 m/s) Isp = Specific impulse (39,240 to 392,400 Ns/kg) Me = Mass (empty) Mt = Mass (total) then ln(Me/Mt) = dV / Isp = 0.76452599388379204892966360856269 to 0.076452599388379204892966360856269 using inverse ln with...

    OHM Planet Nibiru

    We can't see it because it is cloaked by aliens.:lol: I recall a video which said "scientific evidence". It said that one object was spotted years ago and we did not know what it was, and since nothing was said (suspecting silence) then it is Nibiru. Then the video presented the "evidence...

    Question How do you estimate the weight of a vessel?

    So... Non SI: Isp from 4,000 to 40,000 seconds SI: Isp from (4,000 * 9.81) to (40,000 * 9.81) Ns/kg Right?

    What is the most efficient way to send an object to the sun?

    With a VASIMR engine, trajectory becomes a spiral, becuase of its low thrust. See this doc.

    Question How do you estimate the weight of a vessel?

    Isp units are seconds. I estimate 4,000 to 40,000 seconds for the VASIMR addon I want to make. This doc says 3,000 to 20,000 but I want to imagine an improved VASIMR, which is in my opinion feasible for the feature. If I am correct, the limits would be if normal operation allows higher Isp and...

    Question How do you estimate the weight of a vessel?

    Are you sure? If I have: V = 30,000 m/s I = 4,000s to 40,000s ln(M1/M2) = 7.5 to 0.75 then M1/M2 = 1808 to 2.11 So it means M1 is bigger than M2

    General Question Tutorials you would like to see

    The problem of most of C++ tutorials is that they are oriented at learning how to make from simple to complex "Hello world" programs, instead of focusing specifically on creating DLLs for Orbiter(MFDs or vessels for Orbiter). It is like teaching about how to use notepad without talking about...

    What is the most efficient way to send an object to the sun?

    Well, it seems that my idea of VASIMR being usable to drop junk on the sun may actually be possible. If I am not wrong, the DeltaV for Hohmann transfer from LEO to the sun would be near 30,000,000 m/s according to IMFD. Is that correct?

    I am passing through a stage of low inspiration. I sit in front of the computer and even if I know that unfinished ideas are there, I does not feel the need of finishing it. It is almost as if I had lost interest, but I know it is most a matter of inspiration, not just lack of ideas. I ned...
