The Book in Brief
Lord Redgrave brings Zaidie Rennick and her chaperone Mrs. Van Stuyler aboard the Astronef, a spacecraft powered by Professor Rennick's gravity-defying force. Redgrave and Zaidie declare their love, secure political recognition in Washington, marry, and depart with engineer Murgatroyd.
The travelers examine a lifeless Moon and its ruined city before reaching Mars. Hostile airships attack with poison, and Redgrave responds with overwhelming force before the Astronef leaves the exhausted planet. Venus offers the opposite experience: beautiful, peaceful humanoids living without visible conflict.
Beyond the asteroids, Redgrave and Zaidie visit advanced inhabitants on Ganymede and observe Jupiter. Saturn proves stranger and more dangerous, with dense seas, predatory creatures, and monstrous forms. An unknown stellar attraction pulls the Astronef far from course until the source is named Lilla-Zaidie.
On the homeward route the R. Force runs critically low. The Astronef uses planets and Ceres to conserve momentum, then begins falling into the Sun. Redgrave prepares morphine, but Earth rises into the needed line of attraction and draws the ship clear; after a Pacific landing and refueling, the couple returns triumphantly to Washington.
Important Characters
Lord Lenox Redgrave: The wealthy builder and commander of the Astronef, confident in both invention and social authority.
Lilla Zaidie Rennick: An American heiress whose engagement, marriage, and curiosity give the planetary tour its human center.
Mrs. Van Stuyler: Zaidie's chaperone, scandalized by the unconventional courtship but ultimately supportive.
Murgatroyd: Redgrave's loyal engineer, committed to the ship and his inherited duty even at the prospect of death.
Professor Rennick: Zaidie's father, whose discovery of the R. Force makes the Astronef possible.
The Martians: Technically capable but hostile inhabitants whose attack prompts Redgrave's devastating response.
The Venusians: Peaceful birdlike people presented as a harmonious contrast to Mars and Earth.
The Ganymedians: Advanced hosts who welcome the travelers into their crystal cities beneath Jupiter.
Chapter-by-Chapter Summary
The headings and sequence follow the complete Project Gutenberg edition: 20 numbered chapters plus a separate epilogue.
Chapter I
Aboard the Astronef, Redgrave confronts the unprecedented problem of courting Zaidie while carrying her and Mrs. Van Stuyler beyond ordinary society. His technological control gives him an advantage that the chaperone openly distrusts.
Chapter II
Mrs. Van Stuyler challenges Redgrave's methods and the political assumptions surrounding the voyage. Zaidie nevertheless accepts his proposal, turning their apparent captivity into an engagement.
Chapter III
Zaidie explains the promise Redgrave made to her father and rejects a merely aristocratic marriage arranged through wealth. With their intentions clarified, Redgrave prepares to demonstrate the ship's extraordinary reach.
Chapter IV
Redgrave shows Zaidie the Astronef's controls and maneuvers around ships and across the Atlantic with impossible speed. The craft then heads for Washington, where the private adventure must become public.
Chapter V
The Astronef lands at the White House, and Redgrave secures official cooperation while Mrs. Van Stuyler performs her social role. Redgrave and Zaidie marry, and their departure is framed as an Anglo-American mission to other worlds.
Chapter VI
After farewells over New York, the Astronef leaves Earth and makes the Moon its first stop. Zaidie watches her home become a planet before the ship lands on the untouched lunar surface.
Chapter VII
The travelers cross the Moon in protective equipment and explore a vast ruined city and temple. Unable to penetrate every mystery, they photograph the dead civilization and return to the ship.
Chapter VIII
Redgrave surveys lunar craters, possible traces of vanished life, and the unknown hemisphere. The Astronef then leaves the dead Moon for the much longer crossing to Mars.
Chapter IX
Approaching Mars, the travelers study its moons, atmosphere, canals, and cities while speculating about a reception. Redgrave arms the ship before descending toward organized Martian air power.
Chapter X
Martian craft surround the Astronef and attack with poison weapons. Redgrave rams and destroys the immediate threat, while Zaidie recognizes that his violence was driven by fear for her.
Chapter XI
The Astronef follows the surviving Martian command ship to a city, but renewed hostility ends the attempt at contact. Redgrave's weapons kill defenders, and the travelers abandon the depleted world.
Chapter XII
Venus appears as a brilliant cloud-wrapped world with breathable air beneath the veil. The travelers descend into a landscape whose beauty suggests a gentler civilization.
Chapter XIII
Redgrave and Zaidie meet peaceful, winged Venusians and exchange hospitality without a shared language. They leave before attachment or interference can disturb the seemingly innocent society.
Chapter XIV
After crossing the asteroid belt, the Astronef approaches Jupiter and examines its violent atmosphere from a safer distance. On Ganymede, a friendly inhabitant leads them toward a domed crystal city.
Chapter XV
The visitors enter Ganymede's advanced urban world, observe its moving paths and elegant social order, and are welcomed into their host's palace. The moon offers a mature technological counterpart to Venusian innocence.
Chapter XVI
During a week on Ganymede, the travelers learn how its people manage a cooling, drying world and study Jupiter from close range. They then leave the crystal lights behind for Saturn.
Chapter XVII
The Astronef reaches Saturn's rings and descends toward a dense, oceanlike atmosphere crowded with predatory forms. Redgrave keeps the ship moving as larger creatures begin to treat it as prey.
Chapter XVIII
Under Saturn's surface conditions, the Astronef faces immense two-headed monsters and other attackers. Redgrave uses the ship's power to escape the immediate assault and continue the survey.
Chapter XIX
An unexplained gravitational pull drags the Astronef far off course, and neither machinery nor calculation initially accounts for it. Once the vessel passes the invisible star, Redgrave names it Lilla-Zaidie and turns homeward.
Chapter XX
With the R. Force nearly exhausted, the ship rides Ceres and planetary attraction to conserve power, then begins falling into the Sun. Redgrave and Zaidie prepare morphine, but Earth's timely pull saves them at the last possible moment.
Epilogue
The Astronef reenters Earth's neighborhood, lands safely in the Pacific near Peru, and is found by a British cruiser. After replenishing the R. Force, Redgrave, Zaidie, and Murgatroyd fly back to a triumphant reception in Washington.
Ending Explained
What saves the Astronef from the Sun?: Earth enters the right line of attraction just as the ship's heat reaches the couple's agreed limit, shifting the gravitational balance away from the Sun.
Do Redgrave and Zaidie take the morphine?: No. They lift the glasses, but Zaidie sees Earth before either drinks and knocks the dose away.
Where do they first return to Earth?: Redgrave conserves the last force, clears the Andes, and lets the Astronef settle in the Pacific west of Mollendo, Peru.
How does the voyage finally end?: After rescue and refueling, the Astronef flies to Washington and lands where it departed four months earlier.
Themes and Motifs
Marriage as expedition: The honeymoon makes intimacy inseparable from risk, novelty, and joint decision-making.
Technology and mastery: Redgrave's control seems absolute until gravity and dwindling fuel reduce him to calculation and hope.
Alien societies: Mars, Venus, Ganymede, and Saturn become speculative mirrors for aggression, innocence, progress, and predation.
Imperial imagination: Exploration is repeatedly described through ownership, hierarchy, and the power to punish resistance.
Home: The wider the voyage becomes, the more Earth changes from ordinary background into the desired destination.
Content Notes
Includes war and mass killing, poison gas, predatory alien creatures, threatened suicide by morphine, peril in space, imperialist and colonial assumptions, and period gender and racial stereotypes.
About the Book
Best for: readers curious about pre-Wells-and-Burroughs planetary romance and Edwardian visions of the Solar System. Narrative shape: 20 chapters plus an epilogue — courtship, wedding, then a grand tour from the Moon to Saturn and a desperate run home. Central contrast: technological mastery versus the gravity, distance, and fuel arithmetic that finally ignore rank. Overall assessment: 3.5/5 for invention and pace against badly aged science and imperial attitudes. Source-checked scope: 21 distinct reading units in Project Gutenberg eBook #19476; no front matter was counted as narrative content.
