Got ideas? Want to share your thoughts and explore other people’s concepts of the universe of possibilities needed to achieve a human journey beyond our solar system?

Think . . . food, arts & culture, communication, medicine, exotic energy, financial investments now, potential interstellar commerce, astronomy, education, exoplanetology, exobiology, human behavior, politics, astrophysics, IT, clothing, civilizations +  . . . all aspects of the journey.

How can such innovations, knowledge and capabilities be achieved or applied right here on Earth?

Whether you want to take a deep dive or just paddle leisurely around on the surface, 100YSS Nexus has the perfect opportunity. Thought Pools are the evolved form of technical tracks . . . only much better!


Here’s How Nexus Thought Pools™ work.

One CHAIR  +  Five Presenters + Audience + 75 Min. = Thought Pool™.

Five slides and 5 minutes to present the concept. That is 300 seconds for you – the Presenter—to say, show, enact, demonstrate, and play what you want everyone in your pool to know.

After the presentations, the Chair will moderate a Q&A session with all presenters and the audience to digest all that has been heard.

Those presenting concepts in the Thought Pools™ will have their slides included, as well as the opportunity to have a full paper published in the 100YSS NEXUS Proceedings. But first, you have to participate.

Choose your Thought Pool.  Upload your abstract of no more than 250 words with up to 4 research or background references/citations. Abstracts chosen for presentation will be notified by mid-December.

Dwelling in Space: Design for Human Habitats and Systems

Human travel to another star must focus on the “human” in the travel. Current design approaches and philosophies for space missions will not work for long-duration, interstellar travel. What new approaches will need to be developed? What new philosophies of physical, systems and life protocols?  What skillsets should be employed? How do we live? What are our modes and ways of being? To fully explore what it means to dwell in space, we need to consider a wide array of challenges: food, clothing, rituals, entertainment, holidays, mythology, and…?  How are such nuanced concepts integrated in the materials, architecture, structure, information technologies, maintenance and life support?


Design and Engineering for Interstellar Spacecrafts

Design for interstellar probes and crewed vehicles must address the unique characteristics and extreme environment of interstellar space.  Consider materials, capabilities, architectures, systems integration?  What are the steps to define, test and evaluate potential solutions?


Generating, Storing & Controlling “Mega” Energy for Propulsion, Life Support and the Interstellar Journey

The interstellar journey will require prodigious amounts of energy to be generated, stored and controlled.  Propulsion, life support, systems management, communication for example, together and independently will demand massive levels of energy. Fundamental breakthroughs in propulsion and energy are required for interstellar travel to be feasible.  To overcome the formidable time-distance barrier for travel between stars, radical leaps in engineering must be made.  What technologies are currently on the horizon that may fill this need? What is the energy budget? Are there optimum or critical paths that must be explored to achieve functional “mega” energy systems? Alongside challenges are risks; what are?  Considering propulsion, how fast and how far can we travel? 


What To Tell Them About Us?

What is our story? What do we convey to those we’ve yet to encounter? For the future generations on the generation ship, what do we share with them about us here on Earth? For encounters with other life, and advance intelligences?   What message do we have for them now? What and who should be part a first encounter? How do we best ensure our story is recognized and understood? What methodologies?  Are there lessons to be learned from Earth?


Educating for Space: What Facilitates or Hinders Achieving An Interstellar Civilization

How will the process of looking for and then definitively finding “another Earth” impact the social, cultural, economic, educational, religious, legal, political, and ethical aspects of life here on Earth? How will it change us? What might be the costs? The journey beyond our solar system will push current educational practices. Commonly held beliefs and understandings of “learning” may be challenged. What are these educational paradigms that must be incorporated; are they new or old?  What cultures may be models? What is education’s role—formal and informal—in producing effective space travelers and “interstellar citizens”? How is education for space managed today?


The New Frontier: Ethics, Law, Property, Crime, & Family Off Earth

As we move into the commercial era of space exploration with the advent of deep-space and interstellar missions, what are the ethical concerns to be addressed? How do we ensure that human rights both on earth in the development of space exploration and in space itself are protected? What can be done now to promote optimized space ethics framework going forward? What legal issues need to be addressed concerning personal and corporate safety and rights as well as that of nations?  Will the challenges of civilization on Earth follow us off the planet and do we address crime during an interstellar voyage?  If interstellar travel requires ships carrying multiple generations, how will family structures and property be impacted?


The Finances of Space Exploration: Now and into the Future

Financing a human mission to another star may be one the largest investment undertaken. What might be the rewards, risks and measures of success?  What novel and/or traditional methods of investment may be taken now to manage and meet the cost of an interstellar journey?


Micro & Macro Biology in Space: Discovery, Identification, Classification and Care

As “Earth-evolved” humans, plants and other life forms travel deeper in space, we must understand much more about the fundamentals of life mechanisms. We must prepare for radical shifts in nutrition, potential therapeutics, growth and development, physiology, and ethics. Concurrently, as we search for life beyond the Earth, we may need to re-evaluate our perspective of what is defined as “life”.  How do we identify and define? What are we learning about the way space affects the human body? What are our blind spots? What will be potential challenges in a generation ship, if one is necessary? Can we mitigate these challenges through technology? Further, how might the interstellar environment itself be used for life sciences research?


Fueling Terran Innovations by Space Exploration

How do we improve life here on Earth through our space exploration? What current and on-the-horizon technologies for space exploration could be utilized for improvement of life here?


Behavioral & Mental Health for Deep Space Exploration

The very nature of deep space exploration affords significant behavioral and mental health stressors. The environment and conditions will be unique. The resolution of emotional and relational challenges of deep space will require unique innovations. Future space explorers will face significant disruptions to their physiological situation that will ultimately affect mental health. The environments will be confining, and social interactions will be significantly disrupted, while being separated from loved ones on Earth. This session looks at the potential mental and behavioral health challenges and asks how do we best support the ‘human’ in human spaceflight.


Destinations & Interim Missions

Understanding the interstellar medium and the composition of exosolar systems is vital as we contemplate travel to the stars. In addition, as our gaze is drawn many light years away, focusing on closer objectives as stepping-stones to deep space will be essential. Beyond Mars, what missions should be designed to eventuate successful travel to another star? How should—how could—potential destinations be evaluated? What do we know and how do we learn more about space between the stars? What are the missions that would best support a later interstellar mission? What are precursor missions that we should begin developing now? What efforts are already in process?
