Suppose that the technology exists for a spacecraft to launch with low velocity. Horizontal velocity is 0 and after brief acceleration the vertical velocity is constant at 30m/s. After 4 days the craft reaches the high-earth orbit and the propulsion is turned off. What would happen then?
In: 4
It would not be in high Earth orbit. It would fall right back down, because orbits happen as something falls towards Earth and misses. If it’s just falling straight back down it won’t miss.
