Near earth object fuels (neo-fuels): Discovery, prospecting and use (open access)

Near earth object fuels (neo-fuels): Discovery, prospecting and use

The 1992 discovery of a water-ice, near-Earth object (NEO) in the space near Earth is evaluated as a source of rocket fuel and life support materials for Earth orbit use. Nuclear thermal rockets using steam propellant are evaluated and suggested. The space geological formation containing such water-rich NEO`s is described. An architecture couples near-Earth object fuels (neo-fuel) extraction with use in Earth orbits. Preliminary mass payback analyses show that space tanker systems fueled from space can return in excess of 100 times their launched mass from the NEO, per trip. Preliminary cost estimates indicate neo-fuel costs at Earth orbit can be 3 orders of magnitude below today`s cost. A suggested resource verification plan is presented.

NASA Supplier Base: Challenges Exist in Transitioning from the Space Shuttle Program to the Next Generation of Human Space Flight Systems (open access)

NASA Supplier Base: Challenges Exist in Transitioning from the Space Shuttle Program to the Next Generation of Human Space Flight Systems

A letter report issued by the Government Accountability Office with an abstract that begins "The Space Shuttle Program is currently supported by over 1,500 active suppliers, some of whom are the only known or certified source of a particular material, part or service. The retirement of the Shuttle and transition to planned exploration activities, as called for in the President's Vision for Space Exploration, creates the need for NASA to begin making decisions today about its supplier base needs for the future. GAO was asked to (1) describe NASA's plans and processes for managing its supplier base through the Shuttle's retirement and the transition to the Constellation's exploration activities; (2) address factors that could impact the effectiveness of those plans and processes; and (3) identify any other issues that NASA will likely encounter as the agency transitions to and implements the Constellation Program."
