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.

Volume 0: ELEVATIONAL

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.
