VOLUME 0: ELEVATIONAL Table of Contents

Long term deployment 
of space borne enterprises

 require reliable raising to orbit 
of Earth bound resources

without risky rockets.


1. ELEVATE PAYLOADS FROM EARTHHumanity's space presence will eventually require frequent, reliable elevation of materials from Earth to orbit.  BACKGROUND: Traditional Space Elevator's "tether" concept could be a start.
2. UP-LINK TETHER: Climbers Ascend Tether to GEO Node. Associated "strain" might break even the strongest cable at anytime. Thus, a physical cable requires an instant backup capability.
3. DOWN-LINK: Climbers Descend Tether to Marine Anchor.  During normal ops, dedicated downlink tether would provide downward bound service for climbers to return to Earth. 
4. OUT-LINK: Beyond GEO to Apex Anchor.  Thought Experiment (TE) considers innovative ways to leverage Space Elevator (SE) beyond Geosynchronous Equatorial Orbit (GEO).
5. LIFEBOATS: Ride the Virtual Tether.  For a reliable, rapid return to Earth's surface, ride the virtual tether, an Earth based, high speed, particle beam to enable "lifeboats" to land at zero velocity.
6. BASE STATION:  Forgo Down-Link's physical tether; exclusively use lifeboats to travel Down-Link Virtual Tether back to Base Station. However; Base Station will need a reliable particle beam capability.
7. SEVERED TETHER: Several scenarios; some end badly.
8.  ELEVATIONAL ALTERNATIVES  Besides the Space Elevator (SE), there are several other non-rocket proposals which might lift a vehicle and payload from Earth's surface to Earth's orbit.  This chapter briefly describes a few.
9. BEAM ME UP! Thought Experiment (TE) proposes another non-rocket method to reach GEO.  Replace Up-Link's physical tether with a virtual tether, a beam of ions from Base Station. This method can be much more practical than either tether or other elevational alternatives.
10. HIGH STAGE ONE: Leverage Lofstrom's Launch Loop concept to avoid wind and weather in lower atmosphere and get a head start on trip to GEO.
11. CONSTRUCTING SPACE ELEVATOR. Using physical tether to construct subsequent tethers makes sense; HOWEVER, taut tethers eventually snap, and initial tether needs risky rockets.  On the other hand, virtual tether (particle beam) never needs risky rockets nor does it ever "snap".
12. SPACE TUG: Earth Orbits. TE's Space Tug could move vehicles between tethers; but it would be best used in moving Space Habitats among different terrestrial orbits. 
13.  BASE OFF EQUATOR?  Can a tether anchor off the Equator??  Not much.  HOWEVER, a Base Station can locate well away from equator and still project an ion beam toward the GEO Node.
14.   ELEVATIONAL CHALLENGES MAIN CHALLENGE: Quickly move pax/cargo from Earth's Equator to GEO without the absurdly long cable (which might extend 1/4 distance to the Moon!!!!).
15. BEAM ME OUT!!! Expand range of orbital destinations from strictly GEO to well beyond. Even escape Earth's gravity to travel throughout the Solar System.
