Lunar landing -and beyond

J-2 engines are liquid oxygenliquid hydrogen engines, which greatly increases then-weight-lifting ability. Re-starting The S-2 is built and assembled at Downej'. California, bj’ North American. The third stage, the S-48. has only one J-2 engine, with a thrust of 200.000 pounds, but that is enough to put the spacecraft into earth orbit and start it on its way to the, moon. I

[it has finished its work) 1,590,000 pounds of thrust in . its two stages. The Saturn * IB has raised that to 1,800,000 —and refinements are improv- ■ ing on that. But it is the three-stage Saturn 5 that dwarfs them completely with its total thrust power of 8,700,000 pounds. Or to put it another way. The S-l can only put 11 tons in earth orbit. The S-1B can throw 18 tons around the earth —or some 2| tons to the moon. But the mighty Saturn 15 will be able to put 120 tons
