Bp edit easy in answer to the first thread you made, read the mission again. The rocket is not supposed to take-off from earth, it is supposed to be placed on a 30km x 30km orbit to start with.
Simple questions such as that go here.
Your second and third threads were spam, please do not do that.
CAN I USE THE GRIFFIN ENGINE?
Is that from a mod? If so, no you cannot.
what do you mean by Base Game?
Without purchases, the free version of SFS
do you mean no dlc or do you mean no mods?
No DLC is if you are doing the challenges in base game, aka free game. Obviously free players do not have access to DLC features, so if you want to do the challenges like them, no DLC.
Only cosmetic mods and some UI mods are allowed, otherwise it would be unfair.
