As an iconic space conference, ISDC has cemented its status through decades of inspiring discussions, innovation, and collaboration. By spotlighting the evolving landscape of space exploration, ISDC continues to unite enthusiasts, professionals, students, and pioneers under one roof—creating a legacy rooted in education, advocacy, and forward-thinking vision.
The Birth of the Iconic Space Conference
The first space conference known as ISDC (initially called the Space Development Conference) took place in 1982 in Los Angeles. It was co-chaired by Jerry Pournelle and Milton Stevens, with Fred Haise of Apollo 13 serving as Professional Guest of Honor. The event credited attendees—including Buzz Aldrin, Robert Heinlein, and Dick Rutan—with giving enthusiastic feedback that led to it becoming the “First Annual” Conference.
How ISDC Evolved Through the Years
Through consistent annual gatherings, this space conference has grown into a cornerstone of space advocacy. It spans four decades and showcases adaptive growth—from a largely volunteer effort to a global convening of industry, academia, and grassroots advocates.
- Early days (1980s–1990s): Dedicated to building awareness and inspiring a spacefaring future.
- 2000s onward: Shaped by emergent topics like commercial space, planetary defense, space law, and settlement.
- Notable milestones: The 25th ISDC in 2006 marked a defining moment in the conference’s maturity and impact.
What Defines ISDC as a Premier Space Conference Today
ISDC remains a dynamic gathering that connects the space-curious and space-driven:
- Attendee numbers hover between 800–1,000 annually, with 300–400 coming from outside the U.S.—highlighting its global prestige.
- The agenda spans Moon and Mars settlement, space solar power, science policy, deep space exploration, planetary defense, and more—all staples of this ongoing space conference.
- Educational pillars like the NSS’s Gerald K. O’Neill Space Settlement Contest continue to engage future leaders and innovators, reinforcing ISDC’s commitment to education.
A Global and Inclusive Space Conference Experience
Each edition of this space conference brings people from diverse backgrounds together—including engineers, scientists, educators, entrepreneurs, advocates, and students—all in pursuit of a shared vision: the expansion of humanity into space—led by the National Space Society.
In 2025, Orlando hosted the conference under the theme “Together, Beyond!”, celebrating ISDC’s enduring spirit of collaboration and exploration. The upcoming 2026 event is scheduled for June 4–7 in McLean, Virginia, demonstrating the ongoing, global reach of this space conference.
Why the Legacy of ISDC Matters as a Space Conference
