If a company were to send a rocket into space they would need some kind of mining machine on board to mine on, for example, an asteroid. I was wondering if a company already has a good idea for a mining machine and has public details on its weight and price. I need to know this for a project I'm doing on asteroid mining. I hope this question isn't too vague and someone could help me with it. I haven't been able to find anything, only drawings and concept but nothing about size, weight and price.
