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 Flexible Dynamic Reliability Simulation Approach for Predicting the Lifetime Consumption of Extravehicular Spacesuits during Uncertain Extravehicular Activities

Aerospace, 2023
The special use environment and uncertainty of extravehicular activities (EVAs) make it difficult to predict the lifetime consumption of extravehicular spacesuits in the traditional way. This paper presents a flexible reliability dynamic simulation model

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 ...

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.
