Design Considerations of a Space Elevator Apex Anchor and GEO Node – 

This year, ISEC chose to address the design considerations for the Apex Anchor and Geosynchronous Earth Orbit (GEO) Node. As was discussed in the Architectures and Roadmap report, ISEC understands where the technologies are today and where we would like them to be in order to reach Initial Operational Capability (IOC). The goal of this study team is to add to the “body of knowledge” relative to the two topics addressed herein. To ensure complete understanding during this study report, the following definitions were developed: Space Elevator Column, Earth Port & Earth Port Region, GEO Node & GEO Region, and Apex Anchor & Apex Anchor Region. In addition, the needs [functional requirements] were discussed for each of those regions and complexes. Throughout the text, the initial destination is described as the IOC for the Space Transportation System. The Space Elevator Transportation System is comprised of one Earth Port with two tether termini, multiple Apex Anchors supporting 100,000 km Tethers, 14 Tether Climbers, and a single Headquarters and Primary Operations Center. The GEO Node supports the Space Elevator Transportation System with a range of “overhead’ functions; e. g. test, safety, and support.

Space Elevator Apex, Anchor, and Geo

Design Considerations of a Space Elevator Earthport –

  • This study report 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.

Space Elevator Survivability, Space Debris Mitigation –

  • This report focuses on the issue of Space Debris in relation to a Space Elevator. Many people looking at the idea of a Space Elevator for the first time are concerned about how the ever-growing problem of Space Debris will affect it. This report gives an honest look at the numbers, where the Space Elevator is most vulnerable and what can be done about the problem. It shows that space debris is a manageable problem, giving proper foresight and engineering.

Space Elevator Concept of Operations –

  • This report describes and discusses a plausible Operations scenario for a Space Elevator. This report addresses initial commercial operations of a space elevator pair with robotic climbers. This report has been developed to help define a starting point for an initial space elevator infrastructure. It is assumed that there are two space elevators in place to ensure continuation of our escape from the gravity well. It also assumes that a sufficient number of climbers are available for delivering of spacecraft and other payloads to orbit, and, if required, return them to earth. In addition, this report is designed to be the initial operations concept from which many improvements will occur as future knowledge and experience drives infrastructure concept revisions.

Design Considerations for Space Elevator Tether Climbers –

  • The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future.

Space Elevator Architecture and Roadmaps –

  • This 2014 study report establishes a baseline roadmap for designing space elevators for the future. This study addresses critical aspects of space elevator infrastructures: basic architectures and how we will get there with a roadmap. The roadmaps will leverage desired paths to lower risks and identify approaches for pulling together the diverse concepts. The three architectures in the literature today are solid looks at various approaches, while not providing that key element of “how will we get there?” Each path from today to the successful implementation of a space elevator infrastructure must be identified and discussed with respect to hurdles and milestones.
