Unfortunately I took a mission in my career mod as "test rt-10 "hammer" on 100000m orbiting kerbin. I almost have basic equipments. How should I do this. I completed orbiting kerbin. But I can't do this. I need to fire rt-10 while in orbit of kerbin. I don't want to decline this quest. I have 30 parts limit and 140 tons limit. Also I googled videos for this mission but no luck. Thanks.
