Thank you. I don't think of technical challenges as just being about developing better rockets. I think of technical challenges more broadly, which is perhaps me being quirky. For example, I was super excited to see a study suggesting that potatoes can be grown on Mars because potatoes are the only food I know of that is nearly nutritionally complete. So if we can successfully grow potatoes on Mars, that would be a big deal. (Though if anything went wrong, it would be the space exploration version of The Irish Potato Famine all over again. Ugh.) https://news.ycombinator.com/item?id=13823275 https://news.ycombinator.com/item?id=13823275
