Complexity for Survival of Living Systems

Interactions between systems and their mental images enable unlimited increase of complexity. A logical connection between the survivability of living systems and the complexity of their behavior (equivalently, mental complexity) has been established. This connection is an important intermediate result of continuing research on mathematical models that could constitute a unified representation of the evolution of both living and non-living systems. Earlier results of this research were reported in several prior NASA Tech Briefs articles, the two most relevant being “Characteristics of Dynamics of Intelligent Systems” (NPO- 21037), NASA Tech Briefs, Vol. 26, No. 12 (December 2002), page 48; and “Self-Supervised Dynamical Systems” (NPO- 30634) NASA Tech Briefs, Vol. 27, No. 3 (March 2003), page 72.

Using Drained Spacecraft Propellant Tanks for Habitation

A document proposes that future spacecraft for planetary and space exploration be designed to enable reuse of drained propellant tanks for occupancy by humans. This proposal would enable utilization of volume and mass that would otherwise be unavailable and, in some cases, discarded. Such utilization could enable reductions in cost, initial launch mass, and number of launches needed to build up a habitable outpost in orbit about, or on the surface of, a planet or moon. According to the proposal, the large propellant tanks of a spacecraft would be configured to enable crews to gain access to their interiors.

Connecting Node

A paper describes the Octanode, a connecting node that facilitates the integration of multiple docking mechanisms, hatches, windows, and internal and external systems with the use of flat surfaces. The Octanode is a 26-faced Great Rhombicuboctahedron Archimedean solid with six octagon-shaped panels, eight hexagon-shaped panels, and 12 square panels using three unique, simple, flat shapes to construct a spherical approximation. Each flat shape can be constructed with a variety of material and manufacturing techniques, such as honeycomb composite panels or a pocketed skin-stringer configuration, using conventional means.

Electrolytes for Low-Temperature Operation of Li-CFx Cells

A report describes a study of electrolyte compositions selected as candidates for improving the low-temperature performances of primary electrochemical cells that contain lithium anodes and fluorinated carbonaceous (CFx) cathodes. This study complements the developments reported in “Additive for Low-Temperature Operation of Li-(CF)n Cells” (NPO-43579) and Li/CFx Cells Optimized for Low-Temperature Operation (NPO-43585), which appear elsewhere in this issue of NASA Tech Briefs.

Advanced Technologies Will Help Hubble Yield More Remarkable Discoveries

The fourth servicing mission (SM-4) for the Hubble Space Telescope (HST) offered an impressive and unprecedented set of advanced technologies that may yield the most remarkable discoveries and imaging to date of Earth, the solar system, and beyond. The mission was, according to Deputy Associate Director for the HST Development Project Frank Cepollina, “the most complicated mission – from a servicing perspective – that NASA has ever flown.”

Advancing Technologies Harness the Power of Wind, Water, and the Sun

Renewable energy will be the world’s fastest-growing source of electricity generation over the next two decades, although it will still make up a relatively minor portion of the global energy supply, according to the Energy Information Administration. The majority of that increase will come from the use of wind power and water power, or hydropower. The Obama Administration advocates a policy that would require 25% of United States electricity demand be met by renewable energy by 2025.

Laser Tracker Ensures Accurate Alignment of Ares I Components

FARO® Laser Tracker FARO Technologies Lake Mary, FL 800-736-0234 www.faro.com Making its first flights to the International Space Station by the middle of the next decade, the Orion crew exploration vehicle is part of the Constellation Program, which will send human explorers back to the Moon, and then to Mars and other destinations in the solar system. Future astronauts will ride into orbit on Ares I, Orion’s launch vehicle, which uses a single, five-segment solid rocket booster. NASA’s first test flight, called Ares I-X, will provide NASA with an early opportunity to test and prove the hardware, facilities, and ground operations associated with the Ares I.
