It takes 3 essential things to build a Gateway Spaceport:

  • 1. The Money – proper funding that is

there every year, regardless of economic climate.

  • 2. Advanced construction techniques and

technology.

  • 3. People with the will to build a Gateway

Gateway Technical Aspects

  • Highest-level goals: what are we trying to

accomplish?

  • System requirements flow from goals

– “Form Follows Function” (Louis Sullivan)

  • Physical realities set some requirements and

influence others

  • Build in accommodation for obvious extensions

SLIDE 69

High-Level Requirements from Goals

  • Artificial Gravity

– How Much? Lunar? ¼ gee? Mars? ½ gee? – Little is known about gravity magnitude needed to prevent long- term health issues – Opportunity for groundbreaking research on the Gateway

  • Provide for human survival and comfort needs

– Air (Pressure? Composition?) – Water (Distribution system? Recycling?) – Food – Living quarters

  • Avoid designs that induce space-related illnesses

– Limits on rotation rates – Radiation shielding

High-Level Requirements from Physical Realities

  • Orbit option limits

– Altitude

  • Lower à less energy for launches, but more atmospheric drag
  • Higher à less atmospheric drag, but higher energy for launches

and more intense radiation

– Inclination

  • Equatorial à less energy for launches, but long eclipses
  • Sun-synchronous (i ~97°) à continuous sunlight option, but

high launch energy

  • Intermediate?
  • Mitigate orbital debris collision hazard

Accommodate Extensions

  • Wide range of other potential uses

– Science, research

  • Human
  • Animal, plant
  • On-orbit assembly and testing of large, complex spacecraft
  • On-orbit servicing of upper stages for high-energy trajectories

– Exploration

  • Large, complex spacecraft & re-usable upper stages
  • Waypoint for travel to more distant destinations

– Industry

  • On-orbit manufacturing requiring low-gee environment
  • Use of extraterrestrial materials

– Commercial

  • Entertainment and advertising industries
  • Athletics
  • Gateway provides infrastructure for these activities
