Jupiter Lunar Landing
From one of Jupiter’s 12 moons, earth astronauts gaze on this impressive, but bleak, view of the 86,900 mile-diameter planet. More than 316 times the mass of the Earth, Jupiter is seven times further from the sun than Earth; would require voyage of one to two months to reach at velocity of one million feet per second. Max Hunter, Douglas Aircraft Company engineer predicts economically feasible trips to Jupiter will be made through development of nuclear thrust spaceship engines.

Pegasus Intercontinental Passenger Rocket

Pegasus during atmospheric re-entry uses the LH2-cooled plug nozzle as a heat shield. The ballistic transport would convey 172 passengers and freight 7,456 miles (12,000 km.) in 39 min. without exceeding an acceleration of 3g during ascent or re-entry. At the arrival spaceport it would hover on rocket thrust during a soft landing in the vertical attitude.

How re-usable ROMBUS-type launch vehicles can be applied to construction of a temporary lunar base (Project Selena).
Frontiers of Space is peppered with artwork from Douglas, including paintings by Don Charles and James Finnell. In the book, this section was illustrated with (pretty poor) knock-offs. Why? Who knows? These were the masters.
