>up to 250kNs of total impulse and a wet mass of 10-20kg The specific impulse here is 3-6 times better than the one of chemical. Considering the existing tech the solar+ionic seems to be the best option for going to Mars. With some very feasible development of existing tech the nuclear+ionic seems to be the best for farther into Solar and beyond (if I didn't make large mistakes https://news.ycombinator.com/item?id=38445404 https://news.ycombinator.com/item?id=38445404)
