Head-Mounted Dynamic Visual Acuity for G-Transition Effects During Interplanetary Spaceflight: Technology Development and Results from an Early Validation Study

open access: closedAerospace Medicine and Human Performance, 2022
INTRODUCTION: Dynamic visual acuity (DVA) refers to the ability of the eye to discern detail in a moving object and plays an important role whenever rapid physical responses to environmental changes are required, such as while performing tasks onboard a space shuttle.

Aquarius, a reusable water-based interplanetary human spaceflight transport

open access: closedActa Astronautica, 2016
Abstract Attributes of a reusable interplanetary human spaceflight transport are proposed and applied to example transits between the Earth/Moon system and Deimos, the outer moon of Mars. Because the transport is 54% water by mass at an interplanetary departure, it is christened Aquarius. In addition to supporting crew hydration/hygiene, water aboard

Radiation Protection for Human Interplanetary Spaceflight and Planetary Surface Operations

open access: closed, 1993
Radiation protection issues are reviewed for five categories of radiation exposure during human missions to the moon and Mars: trapped radiation belts, galactic cosmic rays, solar flare particle events, planetary surface emissions, and on-board radiation sources.

Integrated shielding systems for manned interplanetary spaceflight

open access: closedAIP Conference Proceedings, 1992
The radiation environment encountered by manned interplanetary missions can have a severe impact on both vehicle design and mission performance. This study investigates the potential impact of radiation protection on interplanetary vehicle design for a manned Mars mission. A systems approach was used to investigate the radiation protection requirements

Neurobiological Effects of Combined Impact of Four-Factor Modeled Interplanetary Spaceflight in Relation to Typological Features of High Nervous Activity

open access: closedРадиационная биология. Радиоэкология / Radiation biology. Radioecology
For the first time, the neurobiological effects of the combined action of four key factors of interplanetary flight, simulated in a ground experiment – prolonged residence in hypomagnetic environment, synchronous exposure to prolonged gamma irradiation and simulated microgravity (antiorthostatic suspension) and irradiation of the head with 12C carbon ...
