01The premise

A new frontier. An old danger.

A space elevator opens the way to Mars. Aboard PEGASUS, an immense crew begins an extraordinary expedition. But a hostile planet is only part of the challenge. Back on Earth, powerful opponents are determined that the mission will never return.

Two crews have already been lost between the planets. Daniel Winstanley has spent forty-five years building a ship that will not fail, but on Earth there are those who believe mankind was never meant to leave it, and they are determined that PEGASUS will.

  • 50,000km

    Space elevator

    Of carbon-nanotube thread, tethering Earth to a counterweight beyond geostationary orbit.

  • 2km+

    Drive train

    A braced linear accelerator running the length of PEGASUS.

  • 30days

    Earth to Mars

    At one hundredth of a G, not the 330 days of a conventional ship.

  • 2crews

    Lost before her

    EAGLE and CONDOR set out for Mars. Neither crew came home.

Two crew members stand in silhouette on the observation deck of PEGASUS, looking out at Mars through a wall of curved windows.

02On board

Welcome aboard Pegasus.

Two carousels · one full gravity · thirty days to Mars

“Not a thing of beauty.”

Bill, commandant of GSS3

“No, Bill, not a thing of beauty.”

Captain Richard Lewis

Not built for beauty.
Built to arrive.

Daniel Winstanley spent forty-five years on her: over two kilometres of braced linear accelerator, nuclear power and contra-rotating carousels, built to carry hundreds to Mars in thirty days, and bring them home.

    Cyclotron stage

    4 × 200 m

    Four cyclotrons in a cruciform give the reaction mass its first push. Inside them, a toroidal tank of powdered iron.

  • 02

    Power complexes

    2 × nuclear

    Two nuclear generator complexes, contra-rotating, shed their waste heat as infra-red through vast radiator vanes.

    Pressure vessel

    2 × 400 m · 1 g

    Two carousels turn in opposite directions, pushing against each other to hold the crew at one full gravity.

    Excursion vehicles

    6 + 2 VTOL

    Six conventional craft and two vertical take-off landers wait at the aft air locks to carry crews down to the surface.

    Drive train

    2 km+ · 0.01 g

    A braced linear accelerator. It manages only one hundredth of a G, but it never has to stop.

Beyond Tranquillity by Victor Crockett. The cover shows a vast starship hovering over a red Martian canyon as a line of explorers walks beneath it.

03The novel

Beyond the known.

An ambitious voyage into the science, courage and human cost of reaching another world.

Half a century after EAGLE and CONDOR were lost in the void, PEGASUS carries not a handful of astronauts but hundreds of explorers to the Red Planet. Told week by week across six months of 2075 and 2076, the story moves between the Martian wilderness and a manhunt on Earth for the preacher known only as the Prophet, a man determined that the mission will never return.

  • 01 · The science

    Engineered, not imagined

    Space elevators, linear accelerators and contra-rotating carousels, worked out by an author who studied aeronautics and ship science.

  • 02 · The people

    Hundreds, far from home

    Half a year in each other's company, and the human frailties that doomed the missions before them.

  • 03 · The threat

    A hunt on Earth

    A fundamentalist preacher who believes mankind should never leave the Earth, and the search to find him in time.

04The journey

The journey, in three worlds.

Earth, where it begins. Mars, where it is going. And the danger that follows it all the way.

  • A space elevator tether rising from the Earth, with a ring-shaped station partway up, above clouds and ocean.

    Where it begins

    A thread to the stars

    A carbon-nanotube thread fifty thousand kilometres long climbs from a ground station on the equator to a counterweight beyond geostationary orbit. From Easter Island, mission control watches every step.

    Where it is going

    Out from Mars Base One

    From the edge of the Hellas Basin, rover crews push out across the planet: the South Pole, Valles Marineris, the Face of Mars at Cydonia, and the slopes of Olympus Mons.

    What follows it

    A war of belief

    Not every danger lies in space. A preacher known as the Prophet believes mankind was never meant to leave the Earth, and his followers will go to almost any length to see PEGASUS fail.
