A fully and rapidly reusable, two-stage, methalox-fueled heavy-lift launch system to LEO

The system's first stage (the booster) returns to the launch site where it lands propulsively and is caught out of the air by arms attached to the launch tower. The second stage achieves a circularized low-earth orbit, deploys up to 100 metric tones of payload, and then deorbits and re-enters Earth's atmosphere. The second stage also lands propulsively and is caught by the tower. The bodies of both stages are made from stainless steel. Both stages can be refilled and relaunched with the booster flying ~20 times per day and the second stage flying about 5 times per day [1], needing only occasional interruptions for servicing to achieve an airplane-like flight cadence.
