Сообщение об ошибке - требуется помощь

Как многие из вас знают (если вы читали мою биографию или просто читали мои предыдущие вопросы), я пытаюсь построить ракету. Код шел хорошо, но как только я разделил свои объекты на 2 файла, файл .h и .cpp, появилось это сообщение об ошибке.

Полный код находится на GitHub, потому что он просто слишком длинный!

Вот сообщение об ошибке :
