Imagine the historic moment when the first Earth-like planet is detected deep across interstellar space. Like an inaccessible jewel it will beckon us. Is this a future home for humanity? What forms of life are already there? How do we get there? What happens when we arrive?

Based on today's technology, traveling to the stars is a long-term proposition. While existing space agencies grapple with sending astronauts beyond Earth orbit, and entrepreneurial firms bring the thrill of spaceflight to the people, no one has taken on the challenge of reaching other habitable worlds; until now.

The Tau Zero Foundation is a volunteer group of scientists, engineers, entrepreneurs, and writers who have agreed to work together toward practical interstellar flight and to use this quest to teach you about science, technology, and our place in the universe. By posting the latest developments and unfinished advancements here, we give students the starting materials to begin their own discoveries. By showing both how daunting and incredible this challenge is, we hope to increase attention on protecting the habitability of Earth while planning journeys into the galaxy. By reaching for the stars we will create benefits every step of the way.

Here is how you can help with this ambition. With enough support we can competitively award grants and scholarships. Help us create a future worth striving for, where humanity can survive and thrive into the heavens. Let's make this dream a reality together.
