"The ISEC promotes the development, construction and operation of a Space Elevator (SE) Infrastructure as a revolutionary and efficient way to space for all humanity."
The March, 2016 issue of the ISEC Newsletter is now available - you can access it here.
This is a very full issue - including information about the latest ISEC Report (Design Characteristics of a Space Elevator Earth Port) which has just been released, a notification that Registration is NOW OPEN for the 2016 ISEC Space Elevator Conference and much, much more!
A new ISEC Report, Design Characteristics of a Space Elevator Earth Port, is now available in both print and electronic formats. This report is the latest in a series of yearly ISEC publications - each one designed to explore a specific aspect of understanding, constructing and/or operating a space elevator. This is the fifth report in this series. Previous report topics included:
- Space Debris Mitigation - Space Elevator Survivability
- Concept of Operations
- Design Considerations on Space Elevator Tether Climber
- Space Elevator Architectures and Roadmaps
This current report, Design Characteristics of a Space Elevator Earth Port, "...provides the International Space Elevator Consortium’s (ISEC) view of the Earth Port (formerly known as the Marine Node) of a Space Elevator system. The Earth Port: Serves as a mechanical and dynamical termination of the space elevator tether; Serves as a port for receiving and sending Ocean Going Vessels (OGVs); Provides landing pads for helicopters from the OGVs; Serves as a facility for attaching and detaching payloads to and from tether climbers and attaching and detaching climbers to and from the tether; Provides tether climber power for the 40 km above the Floating Operations Platform (FOP); and, Provides food and accommodation for crew members as well as power, desalinization, waste management and other such support."
It is available in print format for $9.00 or electronic (pdf) format for $2.15 from the ISEC Store.
A new document has been posted on this website summarizing the major architectural designs of the space elevator which have been proposed over the years. From the introduction:
Space Elevator Architectures have matured since their introduction in the last decade of the 19th century, shown in the 20th century with science fiction expanding many concepts, and finally with modern day designs during the first two decades of the 21st century...
Konstantin Tsiolkovsky, a Russian rocket scientist, pioneered astronautics’ theory in general and specifically conceptualized a building growing to GEO orbit, in 1895 [Tsiolkovski, 1959]. This particular concept focused on aspects of the Geosynchronous orbit. This led to a series of five space elevator architectures over the last 75 years. The first two were significant leaps in understanding, while the last three have lead to the current breadth of concepts:
- In 1960, Yuri Artsutanov presented a real approach visualizing how it could be achieved – a big leap from Tsiolkovsky’s concept.
- Then, in 1974, Jerome Pearson resolved many issues with engineering calculations of the required tether strengths and various approaches for deployment. This was, once again, a leap beyond Tsiolkovsky’s work and set the stage for the “modern design” for space elevators.
- Dr. Edwards established the current baseline for designing space elevator infrastructures at the turn of the century with his book: “Space Elevators” [Edwards, 2002]. He established that the engineering could be accomplished in a reasonable time with reasonable resources. His baseline is solid; and, it was leveraged for the next two refinements of this transportation infrastructure concept.
- The International Academy of Astronautics used Dr. Edwards’ design and the intervening ten years of excellent development work from around the globe. Forty-‐one authors combined to improve the concept and establish new approaches, expanding the Edwards’ baseline.
- The most recent version of space elevator architectures is the recently released view by the Obayashi Corporation. Their set of assumptions of the study established stricter requirements and resulted in a longer developmental period with increased payload capacity.
