At the 2012 100YSS Symposium, Heath Rezabek presented what he calls the 'Vessel Archives' proposal, a strategy for sustaining and conveying Earth's cultural and biological heritage that was directly inspired by Gregory Benford's Library of Life proposal (preprint available here). Heath tells me his major concern is in "improving the prospects for Earth-originating life through the longevity of our interstellar aspirations and through the application of advanced discoveries to enhance life's prospects on Earth." Independent of his role as Outreach and Collaborations Coordinator for Icarus Interstellar's Starship Congress 2013, he is also an accepted presenter for that conference. Recently Heath contacted me about a research project he is conducting with implications for the interstellar community, as explained below. In his non-interstellar work, Heath Rezabek (MLIS) is a futurist librarian, technology grants coordinator, writer, and systems designer. He lives in Austin, TX, where he...

Marc Millis' article "Star Trek, Star Tech," posted on Friday, has been taken down temporarily due to server problems that are now being investigated. As soon as I get these ongoing site maintenance issues resolved, the article will be reposted.

Before getting started on today's post, a reminder that Tau Zero founder Marc Millis and I will be among those interviewed on the History Channel show Star Trek: Secrets of the Universe tonight at 10 PM Eastern US time (0200 UTC on Thursday). Many of the ideas discussed on that show parallel those found in Harry Stine's program for interstellar exploration. Stine drew on the work of Stephen Dole, whose 1964 book Habitable Planets for Man identified 14 stars within a distance of 22 light years in the spectral classes between M2 and F2. Dole thought there was a 43 percent probability of at least one habitable planet around one of these 14 stars, and Stine's interstellar program began with a series of probes that would investigate them, looking first for gas giants. The idea is that a gas giant flags the presence of other, smaller planets, key information in Stine's day. Forty years later, we know how to find gas giants through radial velocity and transit studies. It's true that 'hot...

We become so bedazzled by the assumptions of our time that we can forget how things looked in different eras. 1973 wasn't all that many years ago in the cosmic scheme of things, but the early '70s were a time of surprising optimism when it came to our future in space. As we saw yesterday, physicist Robert Forward laid out a plan for interstellar expansion to a subcommittee of the U.S. House of Representatives in 1975, even as a thoughtful Michael Michaud worked out his own concepts in a series of papers in the Journal of the British Interplanetary Society. But nudging ahead of both men by a few years was G. Harry Stine. Already making a name for himself as a science fiction writer under the pseudonym Lee Correy, Stine was a futuristic thinker who fired readers' imaginations with a cover article in the October, 1973 Analog, an issue whose artwork I reproduce here. Rick Sternbach's cover caught my eye when I first saw this issue while toiling as a grad student that year, but it was the...

Tau Zero founder Marc Millis and I will be among those interviewed on the upcoming History Channel show Star Trek: Secrets of the Universe, which will air this Wednesday at 10 PM Eastern US time (0200 UTC on Thursday). Being a part of this production was great fun, especially since it meant flying out to Oakland for a visit with my son Miles, who is now actively involved in interstellar matters. On long car trips when he was a boy, I would have Miles read Heinlein, Andre Norton and the like aloud while I drove -- terrific memories -- so you can imagine what a kick it is to see him as mesmerized by the human future in space as I am. The idea of getting a payload to another star seemed closer in the days of those car trips. I'm sure that's because we were coming off the successful Apollo program and assumed that a similarly directed effort could push us rapidly to the edge of the Solar System and beyond. It was in 1975, the year of the Apollo-Soyuz Test Project (the last time an Apollo...

The British Interplanetary Society was founded way back in 1933, and included such luminaries as Arthur C. Clarke and Val Cleaver among its early membership. The Institute for Interstellar Studies (I4IS), also based in London, was founded in 2012 and is not, to the best of my knowledge, yet incorporated. Between the two dates and mostly emerging in the first decade of the 21st Century are a number of organizations that in one way or another focus on what I call 'interstellar studies,' meaning science and engineering dedicated to interstellar flight. The trick becomes to keep everything straight. When I started writing my Centauri Dreams book back in 2002, the BIS was a clear model for what a small group of dedicated workers could achieve. It had produced a Moon mission concept as early as the 1930s and went on to create the first fully realized design for an interstellar craft, Project Daedalus. The BIS used the 'red issues' of its journal to focus on interstellar work while JBIS was...

We had a successful launch last night of the ESTCube-1 satellite from Kourou, about which more tomorrow when I'll be talking about electric sails and their uses both interplanetary and interstellar. But this morning, with the Starship Century Symposium rapidly approaching, I wanted to run this overview, which corrects and updates several things in the post I published a couple of weeks ago. Seats are still available for those of you in range. Thanks to Jim Benford for the following: The Starship Century Symposium is the inaugural event at the new Arthur C. Clarke Center for Human Imagination at UC San Diego, Tuesday Wednesday, May 21-22. The program is located here. The symposium celebrates the publication of the Benfords' anthology, Starship Century. Jon Lomberg, the artist who collaborated extensively with Carl Sagan, has read the book and has this comment: Starship Century is the definitive document of this moment in humanity's long climb to the stars. Here you can find the...

Astronautics pioneer Robert H. Goddard is usually thought of in connection with liquid fuel rockets. It was his test flight of such a rocket in March of 1926 that demonstrated a principle he had been working on since patenting two concepts for future engines, one a liquid fuel design, the other a staged rocket using solid fuels. "A Method of Reaching Extreme Altitudes," published in 1920, was a treatise published by the Smithsonian that developed the mathematics behind rocket flight, a report that discussed the possibility of a rocket reaching the Moon. While Goddard's work could be said to have anticipated many technologies subsequently developed by later engineers, the man was not without a visionary streak that went well beyond the near-term, expressing itself on at least one occasion on the subject of interstellar flight. Written in January of 1918, "The Ultimate Migration" was not a scientific paper but merely a set of notes, one that Goddard carefully tucked away from view, as...

by Kelvin F.Long The executive director of the Institute for Interstellar Studies here gives us his thoughts on Star Trek and the designing of starships, with special reference to Enrico Fermi. Kelvin is also Chief Editor for the Journal of the British Interplanetary Society, whose latest conference is coming up. You'll find a poster for the Philosophy of the Starship conference at the end of this post. Like many, I have been inspired and thrilled by the stories of Star Trek. The creation of Gene Roddenberry was a wonderful contribution to our society and culture. I recently came across an old book in the shop window of a store and purchased it straight away. The book was titled The Making of Star Trek, The book on how to write for TV!, by Stephen E.Whitfield and Gene Roddenberry. It was published by Ballantine books in 1968 - the same year that the Stanley Kubrick and Arthur C Clarke 2001: A Space Odyssey came out. What with all this and Project Apollo happening, the late 1960s was...
