Following the inaugural flight of NASAs Ingenuity, science fiction writer Gareth L. Powell considers the future of powered flight on other planets

Earlier this spring, with the maiden flight of NASAs Ingenuity, we celebrated one of the most significant engineering milestones of recent times. Despite having to contend with lower gravity and a thinner atmosphere, an aircraft flew on Mars for the first time. It was the first powered, controlled flight of a human-built vehicle on another planeta significance celebrated by the onboard inclusion of a tiny scrap of material from the Wright brothers first flyer.

The Ingenuity flights were relatively modest in duration, but they were a proof of concept. What comes next will be interesting. The Wright brothers first hop was shorter in length than the wingspan of the Boeing 747, which first took to the skies only sixty-six years after Kitty Hawk. Who knows what we could have flying through the Martian clouds sixty-six years from now?

The first thought I have is of a massive blimp carrying several dozen of these helicopters. Being solar powered, theres little reason it cant stay aloft for days, weeks, maybe even years. Every time the scientists on Earth identify a location of potential interest, the blimp dispatches a helicopter to investigate, soaring over any intervening rough terrain with more ease and speed than a rover.

A helicopter has the potential to get up-close and personal with the strata in a cliff facesomething thats obviously difficult for a ground-based vehicle. A fleet of them could traverse and map the length of the great Valles Marineras canyons without worrying about the bumpy topography.

But why stop with an automated blimp? Viewers of The Martian will remember long sequences of Matt Damon bouncing around in a rover for weeks as he treks towards salvation. But what if hed been able to jump in a helicopter and fly there in a day? When humans start building bases on Mars, helicopters would be as valuable to them as they are for bases in the Arctic and Antarctica. They could be used to airlift personnel to areas of potential interest identified via satellite survey. They could fly missions to resupply forward outposts, and rescue explorers stranded by injury or technical malfunction. They could evengod forbidbe used for security and defence.

Science fiction writers get a lot of mileage from imagining worst-case scenarios. We find drama in the idea of things going wrong. So, while I hope that in the near future we as a species will outgrow our childish infatuation with war, Mars is an entire planet filled with currently unclaimed resources and territory. A bright red jewel hanging just within our reach. Can our acquisitive monkey natures resist squabbling over such a prize? Only 15 years after Wilbur and Orville showed powered flight was possible, squadrons of biplanes were dogfighting in the war-torn skies over France. So, now Im imagining a drone war on Mars, fought remotely by competing governments or corporations, each vying for control of profitable ore deposits or water sources. Helicopter gunships whispering through the thin air, hunting for enemy rovers. Mass accelerators on Phobos and Deimos wiping out mining installations with meteoric bombardment from on high

Air travel shrank the Earth. Instead of spending months sailing to Australia, it is now possible to get there in a matter of a day or two. The same will be true of Mars. If we build the right aircraft, well be able to go anywhere on the planetand dont forget how much smaller Mars is already. Where Earths diameter is 7,926 miles, the diameter of Mars is only 4,220 miles. So, while the technical challenges are huge, the distances are shorter and the gravity is lighter.

But why stop there? Now we know we can engineer machines able to fly in different gravities and through different atmospheric compositions, we should be building choppers capable of exploring the cloud tops of Venus. Huge machines with rotors the size of wind turbines could track the storm systems in Jupiters atmosphere, or cruise the ochre skies of Titan seeking life in its hydrocarbon lakes.

However, Im going to end this months column with a truly science fictional image. Imagine, if you will, a Mars in the not too distant future, where a combination of terraforming techniques have thickened the atmosphere enough for hardy plants to grow and specially adapted animals to roam the surface. And on this new tundra, shaggy herds of reindeer and buffalo graze the tough, wiry grass, watched over by autonomous helicopter shepherds, while overhead, two moons shine in the afternoon sky.

Gareth L. Powell writes science fiction about extraordinary characters wrestling with the question of what it means to be human. He has won and been shortlisted for several major awards, and his Embers of War novels are currently being adapted for television. You can find him on Twitter and Instagram as @garethlpowell.
