I dont understand it:D. I just see green marker and new speedmeter while setting new coordinates. I find yellow bar quite useless atm, because blue bar changes after time while experimenting with direction ship is moving, but its not accurate. Made one of my ships circle earth at endless times simply because power died against gravity to make bigger circless

Hi! So I managed to circle te earth over and over but still dont know how to manover. while ship is moving i set an monouver on its path, but when ship pass over this point nothing happens and ship moves at old direction. What am i doing wrong?
