My first orbit was earlier today between 42km and 54km. It ended with a vielent explosion as the capsule collided with water at 12m/s. Currently working on an orbit using a rocket which consists only of standard parts. Current apogee: 53155m Current perigee: 52443m Still tweaking the orbit but im almost out of fuel but hoping to get the apogee and perigee within 100m of each other. EDIT: Managed a near circular orbit on a different rocket. Apogee: 47,227m perigee: 47,213m It's interesting to note that the altimeter is in the command thing, so flipping the rocket over changes the altitude and can make it hard to judge apogee/perigee
