The Future of Space Exploration

Overview

More than half a century after humans first walked on the Moon, exciting new space adventures are in the works. Thanks to major advances in rocketry, robotics, and other space technologies, humanity is on the verge of returning to the Moon, exploring Mars, building permanent orbiting space stations, expanding space tourism, and pushing the boundaries of exploration throughout the solar system and beyond. The Future of Space Exploration explores these exciting developments in 12 half-hour episodes, hosted by space architect and executive Dr. Ariel Ekblaw. She is joined by experts from diverse space-related fields, each offering unique insights on this greatest of all adventures. Topics include NASA’s Artemis program for a sustained human presence on the Moon, the challenge of a roundtrip mission to Mars, the next generation of space stations, the future of space tourism, and cutting-edge advances in spacesuits, radiation protection, robotic assistants, and in-space living—including more comfortable crew quarters and better food. By the end of this course, you’ll gain a deeper understanding of the challenges, innovations, and possibilities of space exploration—and maybe even be inspired to take part in it yourself!

Course Content

01: Innovating the New Space Frontier

02: To Boldly Go Again: Back to the Moon

More than 50 years after the Apollo Program, humans are heading back to the Moon. But why return, and what’s different this time? Explore the economic and scientific potential of long-term lunar bases, and discover how innovative public-private partnerships are enabling a new generation of astronauts to take that next giant leap. We already know where on the Moon they will land.
Duration: 33 min

03: Dare Mighty Things: Destination Mars

The next destination after the Moon is Mars. Consider how much more perilous this mission will be, with the vast distance from Earth, extended mission duration, harsh radiation, and little prospect of rescue if anything goes wrong. Also investigate the problem of landing on Mars and surviving there for many months before return to Earth is possible. Hear about the detailed planning now underway.

04: The Future of Living in Space

Trace the history of Earth-orbiting space stations—from the Soviet Salyut and the US Skylab in the 1970s to the International Space Station, continuously occupied since 2000, and China’s Tiangong facility. Then explore the exciting next generation of stations, designed to be more commercialized, autonomous, sustainable, and inclusive to open up space for research, industry, and even vacationers.
Duration: 25 min

05: Next-Generation Space Stations

Dr. Ekblaw describes her own groundbreaking work on the next generation of space architecture: a self-assembling, reconfigurable structure capable of constructing itself in space—no need for spacewalking astronauts or robotic arms. Known as TESSERAE, this clever system transcends the limitations of traditional modular space station designs, offering greater flexibility and a touch of fun.
Duration: 24 min

06: Life Support and Futuristic Space Suit Designs

As space voyagers venture farther and farther from Earth, they require advanced radiation protection, robust life support systems, and significantly improved spacesuits. Explore the innovative designs that will enable astronauts to thrive in truly alien environments. These technologies have potential applications on Earth, including radiation therapy, air purification, water recycling, and more.
Duration: 31 min

07: The Future of Food in Space

Investigate the challenges of eating in microgravity, where floating food and crumbs can pose safety risks. Beyond providing essential nutrition, food in space supports mental well-being and social bonding, especially if it is flavorful, varied, and, when possible, fresh. Consider the benefits of fermented foods over freeze-dried options and the necessity of growing food during long Mars missions.
Duration: 22 min

08: From Surviving to Thriving in Space

We’ve mastered how to survive in space; the next hurdle is how to thrive. Survey creative strategies for tackling the singular challenges of spaceflight: the routine disorientation and sometimes debilitating vertigo and nausea caused by weightlessness, the psychological effects of prolonged confinement, and the need for rewarding outlets like art, music, and other forms of self-expression.
Duration: 22 min

09: Space Tourism and the Overview Effect

Look ahead to the future of space tourism, which could feature orbiting resorts offering one-of-a-kind sports, cuisines, and entertainments that are possible only in zero-g. Hear from pioneering space tourists who extol the exhilarating journey, the unmatched sensation of weightlessness, and, above all, the breathtaking view of Earth—a sight they describe as both spiritual and transformative.
Duration: 31 min

10: Using Space to Benefit Life on Earth

Thriving in space means harnessing its resources to benefit humanity. “Off-worlding” opens opportunities to mine the Moon and asteroids for rare materials, generate solar power in space to beam back to Earth, and develop technologies in microgravity that advance medicine and manufacturing. While Earth is humanity’s irreplaceable home, space offers the tools to safeguard and sustain it.

11: Finding Life in the Universe

Are we alone? Join the search for extraterrestrial life—a quest that has yielded intriguing leads. Astronomers have discovered thousands of extrasolar planets, some with Earthlike properties that could support life. Spacecraft have also identified promising regions on Mars, Venus, and certain moons of the outer planets, such as Europa and Enceladus, that might harbor life or evidence of past life.

12: The New Ethical Problems of Space

As humans spread throughout the cosmos, we shouldn’t take our bad habits with us. Consider what an ethical approach to space exploration and settlement might involve. For example, disturbances in the lunar soil, such as footprints, last for many millions of years. Finally, hear from the experts who have contributed throughout the course as they make predictions about our future in space.
