The International Space Development Conference (ISDC) is the annual conference of the National Space Society (NSS). Now in its 37th year, these conferences connect the general public and the NSS membership with leaders of contemporary space efforts. The ISDC provides a nexus for industry, government, scientists, advocates, and the public to meet and discuss the latest issues in space technology, science, policy, commerce, medicine, exploration, settlement and much more. Winners of the annual NASA space settlement Contest annually attend the conference, with several interesting activities and programs. With National Space Society's major goal being to accelerate the process of space exploration and development they also foster astronautics for students by encouraging them and getting them involved.
The first ISDC was held in Los Angeles in 1982. The CoChairmen were Jerry Pournelle and Milton Stevens, and most of the convention staff were volunteers from the Los Angeles Science Fantasy Society (LASFS), although it was emphasized that the conference was professional in nature, and would not be a science fiction convention. The Professional Guest of Honor was Fred Haise of Apollo 13, then CEO of Grumman. Attendees included Buzz Aldrin, Max Hunter, General Daniel Graham, Dick Rutan, and a number of space oriented professionals. Science Fiction author Robert Heinlein was the "fan guest of honor". It was intended as a one of a kind convention, but was successful enough that the attendees acclaimed it the "First Annual" Space Development Conference and voted to hold the second meeting in Houston with Art Dula as Chairman.
The 32nd International Space Development Conference, was held at the La Jolla Hyatt Regency, San Diego, California, May 23–27, 2013. The conference theme is "Global Collaboration in 21st Century Space", inviting all nations of earth to join in the greatest human endeavor, to become an interplanetary species. ISDC 2013 was chaired by Dave Dressler of the "San Diego Space Society". The opening keynote speaker was Bas Lansdorp, CEO of Mars One. Former Indian president Dr. A. P. J. Abdul Kalam spoke at the Friday night Gala dinner about an international initiative involving six nations to build a Space Based Solar Power system (SBSP). Several astronauts presented at ISDC such as Buzz Aldrin, Christopher Ferguson and Mae Jemison.
The International Space Development Conference covers several broad areas of study related to building a spacefaring civilization, including transportation to and through space, technology needed to live and work in space, and Earth-based activities to advocate for or educate others about space development. The overall theme for ISDC 2011 is "From the Ground Up," emphasizing the tools, resources, and social activities that must be accomplished to make a spacefaring civilization a reality. Participants are encouraged not just to describe an ideal "future state," but to think about the technical, economic, or advocacy steps that must be accomplished to achieve a specific goal.
Although the northern Alabama region was hit by tornadoes April 27, resulting in widespread damage and many deaths and injuries, ISDC planners found that local electrical power had been restored to the Von Braun Center and Embassy Suites venues in Huntsville, and restored to the rest of the area within a week or two. Therefore, ISDC 2011 occurred on scheduled. Robert Bigelow, founder and president of Bigelow Aerospace, was the ISDC's Honored Keynote speaker at the Governors' Dinner and Gala. Mr. Bigelow also received the NSS Space Pioneers award for Space Development. The Space Pioneer Award for Science and Engineering was presented to the X-51A WaveRider Team while the prestigious Wernher von Braun award went to the JAXA Hayabusa Team. The von Braun award was presented by Frederick I. Ordway III.
The theme for ISDC 2007 was "From Old Frontiers to New: Celebrating 50 Years of Space Flight" and was hosted by The National Space Society of North Texas chapter of Dallas, Texas over the Memorial Day weekend of May 24–28, 2007.
For the third straight year the presenting sponsor for ISDC '07 was the National Aeronautics and Space Administration (NASA). 2007's ISDC held two pre-conference events; the Symposium on Space Venture Finance on Thursday, May 24 and the bi-annual meeting of the Aerospace Technology Working Group (ATWG) from May 22 – 24.
ISDC 2007 included programs, presentations and exhibits focused on space exploration and settlement, astronomy and scientific research, commercial space ventures, space tourism, and other exciting topics.
The conference also featured displays of real spaceflight hardware, such as Armadillo Aerospace’s historic 'Quad' rocket vehicle. The Quad vehicles were built by space entrepreneur John Carmack and his Armadillo Aerospace team from Mesquite, Texas. One of the Quads, named "Pixel," recently competed in the Wirefly X Prize Cup in Las Cruces, New Mexico.
ISDC 2007 was held in Addison, Texas (metro Dallas area) at the Intercontinental Hotel. Speakers included NASA Johnson Space Center director Michael Coats, U.S. Congressmen Nick Lampson and Ralph Hall, Apollo 17 astronaut and former U.S. Senator Harrison Schmitt, Alex Tai, chief operating officer of Virgin Galactic, local space entrepreneur John Carmack, NASA astronaut Dr. Shannon Lucid, Mars Exploration Rover project leader Dr. Steve Squyers, Mars exploration visionary Robert Zubrin, lunar advocate Dr. Paul Spudis, Space Adventures CEO Eric Anderson, and legendary science fiction author Ben Bova.
Events included speaker tracks on Frontier Transport, Moon and Cislunar (between Moon and Earth) Space Development, The Martian Frontier, International Space Station (ISS) Science, Space Business & Law, Space Medicine, Space Sociology, Space Settlement, Education, faster than light travel, and Solar Power Satellites.
Other conference events included DPRG robot challenges, a game room, the premiere of "Postcards from the Future" and other space movies, filk singing, a kids program, book signings, a space art show and sale, and space-related exhibits. Some exhibits and the space art show were free to the public. For more information see the official website:
