Out among the stars – in the realm where dreams and science fiction conspire to reboot reality – the tangle surrounding the Starliner spacecraft is just the latest chapter in the surreal saga of human spaceflight. Starliner was meant to be taking the first crew to orbit before the curtain dropped. Spectators around the world collectively held their breath.
Three minutes and 50 seconds before it was due to blast off on its inaugural test flight, the Starliner abruptly ground to a halt. The pause – a computer-actuated hold initiated by the ground launch sequencer – was dramatic, as all space programs are; it was broadcast live for all to see. Above the flat, arid plains of Cape Canaveral, in the lightning- and hailstorm-tracking skies of Florida, a spacecraft had rendered a moment inside the perilous and unpredictable world of space travel maddeningly precise. Although that powerful computer is programmed to carry the Starliner into space, it was the computer that effectively stood in the way. And now, as the world tries to understand what happened, the computers are central to the scramble for answers.
The heart of this unanticipated delay is actually a technological maze that experts are struggling to decipher – specifically, the place where the scrub came from is in the ground launch sequencer’s failure to get to the proper operating mode, where the hand-off between software and hardware happens at the most inopportune time. That’s the marvel of space travel – software and hardware have to work in harmony, and work in a tight window to do so.
If the Starliner was stumbling, this setback was not its first such trip-up. At another company, this might not be such a big deal. But the current goal for Starliner, flying humans for the first time in Boeing’s history, was that it was supposed to lift off with crew on board back in early May, and that has seen umpteen delays. Not just delays to the date but knocking the ambition out of the room with them: these conduits must be reliable, and they must be safe.
Hope is not lost either, with the next launch window a tantalising three weeks away. The will and tenacity of the teams at Boeing and NASA becomes a shining example of perseverance. There is still an urgent need to explain the failure of the sequencer. This is an area where the combined expertise of the new space cowboys shines brightly.
Beyond the details of the technical challenges lies the bigger picture of what Starliner represents: a future in which space beyond the confines of our homeworld is less forbidden, the first step in a movement that will stretch spacecraft to destinations near and far, far away. The first mission to carry two astronauts, Butch Wilmore and Suni Williams, to the International Space Station will be a proving ground. It will confirm that Starliner is ready to carry humans to and from their orbital home in service to next-generation spaceflight.
With the promise of new worlds and new trips, we find ourselves asking: what is home? For space travel, Earth is not only the launch pad but also the signal beckoning us back from the void. Earth is the place we long to return to, and understanding that tug teaches us something important about that rocket-ship ride.
Home is an idea that defies distance. It’s the warmth we feel when we reach for anything that reminds us of that feeling of safety, that familiar place, out there in the cold, in the stars. As astronauts fly outward, the thin blue jewel of Earth will always remind them of all we have in common, of our fragility, of our need for one another and, especially for those who have seen it before, of our deep desire for homecoming – for going back to where we started.
No matter how ambitious a journey into the unknown, as with recent projects such as the Starship and the Starliner, home acts as a tether, driving aspiration while anchoring technological ambition in a search for connection as much as discovery. The road maps of the explorers sailing distant seas seek to connect us to the vast cosmos, a big-picture view of the place of humanity within it – connecting us not to that mysterious other world but to the home from which we embarked: our too-small blue ball.
At this very moment, as the Starliner steels itself for its next chance to make that climb into the beyond, and as we all collectively cross our fingers and hold our breaths, we would do well to reflect on that deeper journey we continue to embark on. A journey not only of distance and exploration, but of understanding and return – a journey that, no matter how far we reach, will always take us back to where we started from.
