<s>[INST] Do you ever wake up with the fear that there's going to be this Hindenburg moment for SpaceX where ... [/INST] We've had many Hindenburg. Well, we've never had Hindenburg moments with people, which is very important. Big difference. We've blown up quite a few rockets. So there's a whole compilation online that we put together and others put together, it's showing rockets are hard. I mean, the sheer amount of energy going through a rocket boggles the mind. So, you know, getting out of Earth's gravity well is difficult. We have a strong gravity and a thick atmosphere. And Mars, which is less than 40 percent, it's like, 37 percent of Earth's gravity and has a thin atmosphere. The ship alone can go all the way from the surface of Mars to the surface of Earth. Whereas getting to Mars requires a giant booster and orbital refilling. </s>
