Medieval?
editIt says, “It was named after Conrad Haas, a medieval rocket pioneer....” On Conrad Haas, it says he lived (1509-1576). That's not medieval. Middle Ages are from about 476-1492. (476: Roman Empire falls; 1492: Columbus discovers America.)--Solomonfromfinland (talk) 06:07, 19 July 2013 (UTC)
SSTO?
editIt says Haas 2c is to be an SSTO. That's not realistic. Executor (rocket engine) says said engine has a specific impulse of 270 s (sea level) and 295 s (vacuum), burning RP-1 and LOX. Why would they attempt SSTO on such an inefficient engine? RD-180, which is used on Atlas V's first stage and also burns RP-1 and LOX, has specific impulse of 311 s (sea level) and 338 s (vacuum). Also, the rocket is very small, at only 16 metric tons at liftoff. This means that its ballistic coefficient is poor, so it will lose alot of delta-V to air resistance. Are they really un-practical enough to attempt SSTO on a small, inefficient rocket instead of a large, efficient one?--Solomonfromfinland (talk) 06:27, 19 July 2013 (UTC)
From what I gather the primary issue is that of cost. Considering they are likely aiming for a five digit($) price per rocket I'd say let them face whatever difficulties. If it pans out, kudos to them. The price per kilo to orbit would be sub $1,000. Granted it would be a decaying orbit, but still... 95.76.136.228 (talk) 10:20, 27 September 2013 (UTC)
