Gravity: The Key to Life and Propulsion on The High Frontier.  Enabling Permanent Human Settlement On The High Frontier.

February 27th 2017 Space Studies Institute President Gary C Hudson spoke at the Silicon Valley Space Center/AIAA Tech Talk meeting in Santa Clara, California about two important SSI programs: G-Lab, the free flying reduced gravity spinner co-orbited with ISS and EPI, supporting fundamental R&D for true “Space Drives.”

It was a fascinating night and we hope that all SSI Associates will make the time to enjoy this video.

Many thanks to Dr. Sean Casey and Rick Kwan of the Silicon Valley Space Center, the AIAA-SF and the Santa Clara Hacker Dojo.

From the SSI Yahoo Group: A Paper from Al Globus on ELEO Settlement

Al Globus, Senior Research Engineer for San Jose University at NASA Ames and editor-in-chief of the NSS Space Settlement Journal posted this very interesting note at the Space Studies Institute Yahoo Group:

“The latest version of this Equatorial Low Earth Orbit (ELEO) settlement paper is in Space Review this week. They did a great job of formatting and presenting the paper. The biggest change from earlier versions is the SpaceX Interplanetary Transportation System (ITS) announced by Elon Musk which has major implications for ELEO settlement.

Specifically, the ITS is a two leg system to transport people and supplies from Earth to Mars. The first leg is Earth to Low Earth Orbit and the target costs are just about exactly what ELEO settlement needs. The ITS engine is in the late stages of development aimed at operational use in the Falcon 9 and Heavy. A large composite tank has also been fabricated for test. This is no mere paper study.”

SSI Associates should make time to read this paper, it is fascinating:

At long last, the Proceedings of the first Estes Park Advanced Propulsion Workshop, sponsored by SSI, are ready for general release.  The free PDF is downloadable by clicking on the link below.

Dedicated to Jim Woodward on the occasion of his 75th birthday, the editors – Lance Williams and Heidi Fearn – have spent countless hours preparing the volume, collecting contributors’ papers, or summarizing talks where no papers were available.  SSI and the advanced propulsion community owes them thanks for their tireless efforts.

Besides the main body of the work, they report on the tone and tenor of the gathering, from impromptu discussions that took place during and after talks and at the reception that Jim Woodward’s neighbors Wade and Lanier Whilden graciously hosted for attendees.  Several unscheduled and entertaining evening talks on unconventional topics have also been summarized.

We hope you will find the main body of the technical papers worth reading and that the ideas and results presented therein will stimulate even more attention and experimentation into this controversial but important area of research.

SSI 10th Conference Remarks Document Cover

This is the 90th Birthday week of Space Studies Institute’s founder Gerard K. O’Neill and over on the Space Studies Institute Facebook Page we’ve been posting some snippets from Gerry’s Opening Remarks at the 10th SSI-Princeton Conference on Space Manufacturing.

It was O’Neill’s last time together with the whole SSI membership, scientists and engineers and this short conference opener was, as they say, “A Doozy.”  There is nothing unclear or fluffy in the Professor’s words.

Acquiring copies of the complete collection of SSI Conference Proceedings is an expensive task for individuals, mostly these books are part of private research libraries, so there’s a chance that many even in the SSI family haven’t yet seen all of the details of the real work that can make The High Frontier Concept a reality.  We’re working on ways to make the volumes more accessible, but for right now we’d like to share with you this one small but very important chapter… The full text of those Gerard K. O’Neill Opening Remarks.

If you’ve been reading the quotes on the Facebook page and want more in context, or if you just stopped by here and are open for a very good read, it’s all yours on a free PDF from SSI.  I’ve read it myself and it clocks in at less than 6 minutes… but it packs quite a punch.

90 times Earth has moved around the sun since Gerard O’Neill was born, 40 times since he and Tasha started SSI to work on making a better future for Human Beings.  How many more times does the planet have to run in circles before we take it upon ourselves to pitch in and help its people truly get somewhere?

It’s high time to get people moving toward The High Frontier.
