The Sky at Night – 2075: Our Place in Space

The Sky at Night – 2075: Our Place in Space – The Sky at Night is embarking on an extraordinary journey into the future, looking at how space exploration will revolutionize life on Earth over the next half-century. As humanity’s presence in the cosmos expands, we will encounter unprecedented challenges, from redefining the role and qualifications of astronauts to confronting the looming crisis of space debris.

Additionally, we’ll grapple with the profound effects that extended time in space will have on the human body—an organism finely adapted to Earth’s unique environment. Armed with early access to a groundbreaking report from the Royal Society on humanity’s trajectory in space, the Sky at Night team sets out on a mission to explore not just how we will survive, but how we will thrive among the stars. Our future—our place in space—is on the line.

The path to becoming an astronaut has always been paved with rigorous physical and mental tests that only a select few could pass. But as our ambitions in space grow, so too does the need to diversify the people we send beyond Earth. It may be time to challenge the strict criteria that have traditionally defined who can be an astronaut. The European Space Agency (ESA) is already leading the charge with their innovative study known as Fly!, which is investigating the possibility of sending individuals with physical disabilities into space. This forward-thinking program could redefine who gets to be part of the next generation of astronauts.

Presenter Chris Lintott travels to the European Astronaut Centre in Cologne, where he meets John McFall, one of the newest members of ESA’s astronaut reserve. John is no stranger to challenges; he’s an orthopaedic surgeon and a medal-winning Paralympian. Now, he has broken yet another barrier as the first recruit of the Fly! program. The study aims to explore whether someone with a disability, like McFall, can live and work effectively in space.

Chris takes viewers behind the scenes to discover the rigorous and often grueling training that John undergoes as he prepares for what could be one of humanity’s most audacious endeavors—opening the frontier of space to a broader and more inclusive population. Through this mission, McFall hopes to not only prove that disabled individuals can contribute meaningfully to space exploration but also pave the way for a future where access to space is not limited by physical conditions.

While training to go to space is challenging enough, living on the Moon or Mars is an entirely different level of difficulty. Our bodies have evolved to function under the specific conditions of Earth’s gravity, and in the low-gravity environments of other celestial bodies, we may encounter severe biological issues. Prolonged exposure to reduced gravity can wreak havoc on the human body, affecting everything from our muscles and bones to our cardiovascular and immune systems.

At the prestigious Royal Society in London, Maggie Aderin-Pocock sits down with Professor Kevin Fong, a leading expert in space medicine, to delve into the complexities of keeping humans healthy in space. The conversation touches on some of the most critical medical questions facing future astronauts. What happens to the human body during extended stays on the Moon or Mars, where gravity is much weaker than on Earth? How would an astronaut handle a medical emergency while millions of miles from Earth, with limited resources? Could a person survive, or even thrive, after spending years in such extreme conditions?

Space medicine is a rapidly evolving field, with researchers working to understand how long-term space travel affects the human body at a fundamental level. Without Earth’s gravity, bones lose density, muscles atrophy, and even the way fluids move through the body changes, leading to a host of potential health issues. There’s also the psychological strain of being isolated from Earth, which could be just as taxing as the physical challenges. These are not just theoretical concerns; they are practical problems that must be solved if we ever hope to build sustainable human settlements on the Moon or Mars.

One of the most intriguing and unsettling questions is whether humans could reproduce in space. Could a baby be born in zero gravity or on another planet? The idea may seem far-fetched, but if humanity is to establish long-term colonies beyond Earth, it’s a question we’ll eventually need to answer. Pregnancy and childbirth are complex processes deeply tied to Earth’s environment, and the absence of gravity could fundamentally alter everything from fetal development to labor. Researchers are only beginning to scratch the surface of this topic, but the implications are profound—space exploration could challenge the very essence of what it means to be human.

The future of humanity in space is closer than ever, but it’s filled with unknowns. How will our bodies adapt to life beyond Earth? What innovations will allow us to overcome the challenges of living in space? And perhaps most crucially, how can we make space accessible to more than just a privileged few? These are the questions that The Sky at Night seeks to answer, as it looks ahead to 2075 and beyond.

As we stand on the threshold of a new space age, it’s clear that the next 50 years will bring revolutionary changes—not just for science and technology, but for society as a whole. The sky, as we know it, may soon cease to be the limit. Whether we are building cities on Mars, finding solutions to Earth’s most pressing problems through space-based research, or rewriting the very definition of an astronaut, one thing is certain: our place in space is evolving, and the journey is only just beginning.

Innovative Solutions for Tackling Space Debris: Astroscale’s Pioneering Missions

While Maggie Aderin-Pocock and Professor Kevin Fong delve into the complex medical challenges of space exploration, another equally pressing issue is being addressed by George Dransfield. He heads to Oxfordshire to visit Astroscale, a pioneering company tackling one of the most urgent problems in modern space science—space debris. The amount of space junk orbiting our planet is staggering, with an estimated 130 million pieces of debris now circling Earth. This figure continues to rise as more satellites are launched and defunct spacecraft are left to drift in orbit. If left unchecked, this growing cloud of debris could threaten future space missions and even our ability to use satellite-based technology here on Earth.

George meets Dr. Mekhi Dhesi, one of Astroscale’s lead engineers, to explore the innovative solutions they are developing to clear up space junk. One of their most exciting missions is ELSA-M, a spacecraft designed to remove defunct satellites from orbit. The ELSA-M uses powerful magnets to latch onto non-functional satellites and tow them safely out of orbit, preventing potential collisions with other space assets. This mission represents a significant step forward in space cleanup efforts and is one of the few active attempts to directly address the growing problem of orbital debris.

Astroscale isn’t stopping with just one solution. They’re also developing Cosmic, another spacecraft equipped with a robotic arm capable of grabbing onto pieces of debris. This advanced technology allows Cosmic to capture and remove debris that may be too small or irregularly shaped for ELSA-M’s magnetic system. With this two-pronged approach, Astroscale is demonstrating how innovative engineering can help safeguard the future of space exploration by keeping Earth’s orbit clear of dangerous debris. Dr. Dhesi explains that Astroscale’s ultimate goal is to create a sustainable space environment, where responsible management of space traffic and debris ensures that future generations can continue to benefit from space-based technologies without the risk of catastrophic collisions.

The problem of space junk isn’t just one for engineers and astronauts, though. It’s also becoming a growing nuisance for stargazers and amateur astronomers. The sheer number of satellites now orbiting Earth has introduced a new challenge for those trying to observe the night sky. As more satellites reflect sunlight, they leave bright trails across astronomical images, obscuring views of distant stars and galaxies. For anyone passionate about astronomy, this growing satellite traffic is a frustrating development.

Thankfully, resident astronomer Pete Lawrence has some clever strategies to help mitigate the impact of satellites on night-sky observations. He offers practical tips for distinguishing between satellites and meteors, which can often look similar to the untrained eye. More importantly, Pete highlights the use of smart telescopes, which have built-in software capable of removing satellite trails from deep sky images. These advanced tools help astronomers regain some control over their observations, ensuring that the beauty of the cosmos remains visible despite the increasing number of man-made objects in orbit.

The Future of Space Exploration: Ethical Challenges and Human Expansion to Mars

But space debris and satellite interference are just the beginning of the challenges we face as we venture deeper into space. At the Royal Society, Maggie Aderin-Pocock returns to sit down with Professor Suzie Imber, a renowned planetary scientist and co-chair of the landmark Space: 2075 report. Together, they explore some of the most profound questions that will shape humanity’s journey into the cosmos over the next 50 years. As we push further into space, one of the most pressing issues is how to ensure that space exploration benefits all of humanity, not just a select few.

Professor Imber explains that the commercialization of space is both an opportunity and a potential source of concern. While private companies like SpaceX, Blue Origin, and others have accelerated technological progress and lowered the cost of space travel, there are growing worries about the long-term implications of privatizing access to space. If space becomes dominated by a handful of powerful corporations, will the benefits of space exploration be distributed fairly? Or will space become yet another arena where the wealthiest entities hold all the power?

Maggie and Professor Imber also discuss the social and ethical considerations of human expansion into space. Should humanity focus on solving pressing issues here on Earth—like climate change, poverty, and inequality—before investing vast resources into space colonization? Or is space exploration an essential part of our survival, offering solutions that could address some of our planet’s most critical problems? For instance, mining asteroids for rare minerals could reduce the strain on Earth’s natural resources, and space-based solar power could provide clean, limitless energy. These potential benefits underscore the importance of ensuring that space exploration remains accessible and beneficial to all.

As the conversation turns toward the future of space exploration, Professor Imber shares her thoughts on one of the most exciting and contentious questions: Will there be people living on Mars by 2075? While the idea of human colonies on the Red Planet has captured the public imagination, the challenges of making it a reality are immense. Mars is an unforgiving environment, with extreme temperatures, a thin atmosphere, and no readily available water. However, with rapid advancements in technology, including developments in space medicine, habitat construction, and life-support systems, the dream of living on Mars is becoming more tangible.

Professor Imber remains cautiously optimistic. She believes that, while it may not happen overnight, human settlement on Mars is within reach if we continue to invest in research and collaborate on an international scale. The next few decades will be critical in determining whether humanity can extend its reach beyond Earth—and if we can do so in a way that benefits all people, not just the few who have the resources to make the journey.

As we look toward 2075, it’s clear that space will play an increasingly important role in our future. From cleaning up space debris and mitigating the impact of satellites on astronomy to addressing the ethical implications of space colonization, the decisions we make today will shape the cosmos for generations to come. Whether we’re building habitats on Mars or revolutionizing life on Earth through space-based technologies, one thing is certain: humanity’s place in space is just beginning to unfold.
