The Utility of a Hyperspectral Infrared Imager for Crewed Exploration of Planetary Bodies

Earth and Space Science
Planetary analog simulations are a powerful exercise for understanding the utility of deployable instruments, their operational protocols, and the visualization of data products during ExtraVehicular Activities (EVAs).

Neck-vein thrombosis during spaceflight. [PDF]

Br J Clin Pharmacol
Spaceflight imposes unique environmental challenges, including weightlessness, increased radiation exposure and confinement, which can lead to unexpected health effects. One such example is neck‐vein thrombosis, a condition rarely seen on Earth without predisposing factors such as venous catheters or infections.

A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity. [PDF]

Adv Sci (Weinh)
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...

Artificial neural network-based adaptive fluid temperature regulation of extravehicular activity suit

Medicine in Novel Technology and Devices, 2021
The extravehicular activity (EVA) suit is an important component of the life-support system for astronauts working outside of a space craft. In view of the problem that the EVA suit's thermal control system cannot be reliably operated by the astronaut ...

We have liftoff: A discovery study to use artificial intelligence to identify adaptative profiles for future space missions. [PDF]

Physiol Rep
Abstract Long‐duration space missions will challenge astronauts' adaptive capacities. Interoception and heart rate variability (HRV), reflecting parasympathetic activity, are increasingly recognized as predictors of adaptation and health. This study investigated whether artificial intelligence may predict adaptation profiles from interoceptive and HRV ...

Tactile data entry for extravehicular activity [PDF]

2011 IEEE World Haptics Conference, 2011
In the task-saturated environment of extravehicular activity (EVA), an astronaut's ability to leverage suit-integrated information systems is limited by a lack of options for data entry. In particular, bulky gloves inhibit the ability to interact with standard computing interfaces such as a mouse or keyboard.

A Commercial Extravehicular Activity Space Suit [PDF]

New Space, 2020
Extravehicular activity (EVA) space suits are complex, expensive, and difficult to operate and manage. However, EVA is all but required for any human spaceflight operation in orbit or beyond. Final Frontier Design (FFD) has developed and is currently in beta testing of a commercially focused and complete EVA space suit system. This article presents the
