1. ROOST was designed for giant single-stage boosters of future like that in drawings here. The boosters, 50 feet in diameter and 173 feet tall, would weigh 10 million pounds loaded and have a cluster of 12 engines generating a mighty thrust of 12 million pounds.
2. Booster speeds toward earth orbit carry a 160-ton payload that might be a nuclear stage with a manned capsule for moon or outer-space exploration. Cutaway of the booster shows how the deflated recovery bags are stored.
3. In earth orbit, payload has separated, and recovery bags popped out from rear of rocket begin to inflate, throwing off protective plates. Here conical bag begins to take shape.
4. Inflated cone-shaped bag enshrouds rocket while doughnut grips its middle like a choke collar. Booster can remain in orbit 24 hours until triggered for re-entry.
5. As Roost settles gently in the sea, waiting surface ships pick up the dangling towlines to salvage the costly booster.
