I am pretty confident that they have even bigger plans for the future. Sure, they just launched one of the most powerful rockets humans have ever created but for those who don't know, Elon Musk is a very, very ambitious man and I am 99,9% sure that he won't stop here.
I watched the interview of Mr. Musk from the event and even though journalists kept asking him about his magnificent accomplishment, the man was like "Aaaa, no big deal...Let's talk about my next goal." Whoever saw the interview knows what I am talking about. Elon Musk has a certain ambition and he made it clear that his company plans to send the first colonizers to live on Mars.
