Development of the Self-Powered Extravehicular Mobility Unit Extravehicular Activity Data Recorder [PDF]

open access: yes42nd International Conference on Environmental Systems, 2012
The Self-Powered Extravehicular Mobility Unit (EMU) Extravehicular Activity (EVA) Data Recorder (SPEEDR) is a field-programmable gate array (FPGA)-based device designed to collect high-rate EMU Primary Life Support Subsystem (PLSS) data for download at a later time.

Cardiac arrhythmias during long-duration spaceflights

open access: yesJournal of Arrhythmia, 2014
Few studies have investigated cardiac arrhythmias during spaceflight. Atrial and ventricular premature contractions, short-duration atrial fibrillation, and non-sustained ventricular tachycardia were reported by previous spaceflight programs.

Addressing the envisioned world problem: a case study in human spaceflight operations

open access: yesDesign Science, 2019
The construction of future technological systems in work domains that do not yet exist, known as the envisioned world problem, is an increasingly important topic for designers, particularly given the rapid rate of technological advancement in the modern ...

Revisiting decompression sickness risk and mobility in the context of the SmartSuit, a hybrid planetary spacesuit

open access: yesnpj Microgravity, 2021
Gas pressurized spacesuits are cumbersome, cause injuries, and are metabolically expensive. Decreasing the gas pressure of the spacesuit is an effective method for improving mobility, but reduction in the total spacesuit pressure also results in a higher

Indices of Increased Decompression Stress Following Long-Term Bed Rest

open access: yesFrontiers in Physiology, 2018
Human extravehicular activity (EVA) is essential to space exploration and involves risk of decompression sickness (DCS). On Earth, the effect of microgravity on physiological systems is simulated in an experimental model where subjects are confined to a ...

The Apollo Number: space suits, self-support, and the walk-run transition. [PDF]

open access: yesPLoS ONE, 2009
BackgroundHow space suits affect the preferred walk-run transition is an open question with relevance to human biomechanics and planetary extravehicular activity. Walking and running energetics differ; in reduced gravity (

Exoskeleton energetics: Implications for planetary extravehicular activity [PDF]

open access: yes, 2017
Humans first visited another world nearly 50 years ago and are poised to return to the Moon and visit Mars in the coming decade(s). Developing a space suit that supports safe, efficient, and effective exploration despite the extremes of temperature ...
