    Could Nuclear Thermal Rockets Revolutionize Space Travel?

    Mandrake, About youir reactor, for how long could it maintain 3000MWt? Which was the total estimated reactor mass? Was it possible to make it work to let's say 3MWt when not propelling the spacecraft ?

    Could Nuclear Thermal Rockets Revolutionize Space Travel?

    Concerning what you say that electrical engines are heavy, I strongly disagree. In fact, the problem with the MHD and the ion propulsion is that it needs a high level of power; we are speaking from 15MW to 5GW (depending on the efficiency you want and the time to accelerate you have). That means...

    Does the Sun's Gravitational Effect Influence the Calculation of Star Distances?

    Well, you say slight. I do agree, it is slight, but nevertheless, it lasts for 1 hour-light (1080MMKm). At this distance, the escape velocity is still a big number (around 15Km/s over the Earth's ground escape velocity) and you have been at light speed for 1h You know slight + long time =...

    Stars closer than thought. How the sun affects the light path

    Distance to star, much little Considering the effects of the relativity theory in terms of the curvation of space, I am wondering if for the calculation of the distance to the stars using the parallax method (below 100ly), the effect that the sun is creating a deformation in the solar system...

    Considering the effects of the relativity theory in terms of the curvation of space, I am wondering if for the calculation of the distance to the stars using the parallax method (below 100ly), the effect that the sun is creating a deformation in the solar system is taken into consideration. The...
