I am still testing to figure out all of these values. Unladen weight is about 750,000kg, hydrogen is needed from 2,800m to 15km (possibly less). It currently has two hydrogen tanks, enough for many takeoffs/landings, and 2 cargo containers. It has room for more cargo but I limited this number to avoid overburdening. I was able to take off with less than 40% hydrogen from one tank before switching to ion thrusters. Also, it will catch itself in a fall WITHOUT hydrogen if facing the right direction.

So it will need hydrogen thrusters to escape atmosphere starting from 2800m (is it with ion?) and untill 15km...
How much ice it will need for such distance? How much hydrogen it can store? And what is its weight (both max and min load)? Since it has launchers I assume ship has containers, how much cargo it can store?
