Driger

I can recreate this with various sized asteroids. The highest efficiency I have been able to achieve is 1 ton of ore per 2 tons of asteroid resources.

Thank you, I didn't realize having the drill at 100% efficiency had an impact on mass loss. Originally I thought that efficiency only mattered for the speed of extraction. I guess I will put some radiators on my asteroid miner

Ive run into a curious issue with my asteroid mining endevours. I latched onto a class c with 161 tons of resources. Deployed my drillomatic jr ensured my full sized isru was turned off then watched as i only filled my empty ore tank to 634 units. Where did all those resources go? How do I not waste so much? I only mined 6 tons of ore from a 161 ton resource asteroid. Whats up with that?

Hi everyone, I’m trying to predict the maximum height of my rocket flying straight up in the kerbin atmosphere and am stuck. My ship is one flea booster with a Mk1 pod and a Mk16 chute flown by a kerbal. It weighs 2.44t full and 1.39t empty. The flea has an ISP of 140 asl - 165vac. Using the asl ISP I got 772.0166 delta v. From here I used some kinematics equations and figured that the speed at the end of the burn should be 685.16m/s and the maximum height of the flight would be 23926.72m When I tested it out in the sandbox with drag turned off I ended up going 29606m high and the speed at the end of the burn was 704m/s So I think the numbers were off because as the rocket flys up the ISP improves meaning I actually had more delta v than calculated. Another thing I thought might have affected it was the force of gravity changing the further away from kerbin I got (I used a constant 9.81). How do I improve my calculations to account for changing ISP and gravity? Or was I missing something else? If anyone is feeling ambitious I would also really appreciate an explanation of how to add drag in as well because the formulas on the atmosphere wiki are not making any sense to me.
