# Bioastronautics and the Human at the Centre of the Mission

 Bioastronautics covers the biological and medical dimensions of spaceflight, and is the discipline at the centre of Suited for the Stars.

[Suited for the Stars](https://www.imdb.com/title/tt35198637/) places bioastronautics at the centre of its account.

The discipline covers the biological and medical dimensions of [space](https://www.metakosmos.co/pulse/space)flight: how the body responds to microgravity, radiation, pressure change, isolation and altered light cycles, and what engineering keeps a person functional through those.

## THE PHYSIOLOGICAL LIMITS

The US Extravehicular Mobility Unit operates at 4.3 psi. NASA re[sea](https://www.metakosmos.co/pulse/sea)rch documents that the pressurised suit requires the astronaut to expend energy deforming it, contributing to musculoskeletal injury, with hand and finger injuries most common in training and flight.

Standard resting prebreathe protocols require four hours of pure oxygen before a spacewalk to avoid decompression sickness.

## TEAM COMPOSITION

Coverage of Metakosmos consistently describes a team of engineers, medical doctors and scientists.

Research activity runs through [LABS](https://www.metakosmos.co/labs) as a distinct function spanning academic collaboration, defence research and applied industrial work.

## TERRESTRIAL EQUIVALENTS

A saturation diver managing inert gas kinetics and cognitive imp[air](https://www.metakosmos.co/pulse/air)ment at depth, a pilot managing G-tolerance and hypoxia at altitude, and a CBRN operator managing heat strain in an encapsulating ensemble face bioastronautics problems under other names.

The [PULSE layer](https://www.metakosmos.co/pulse) runs a common physiological architecture across [land](https://www.metakosmos.co/pulse/land), sea, air and space variants.

## MEASUREMENT

The suit is the only element in continuous contact with the operator across a mission, which makes it the instrumentation point and sensing a hardware design constraint.

Establishing what measurements mean requires [human surrogate testing](https://www.metakosmos.co/prove/synhum), because the required exposures cannot be applied to a person.

## RESEARCH RELATIONSHIPS

The Kolling Institute, one of Australia's oldest medical research institutions, collaborates on musculoskeletal research and served as a Kernel360 beta testing partner. Academic Director Professor James Elliott has described the alignment between the institute's muscle mapping work and the company's objectives.
