i) at least one re-humidifier adapted to re-humidify such portions of such expired breath;
j) wherein said at least one re-humidifier comprises at least one moisture returner adapted to return the captured moisture from said at least one moisture capture to such portions of such expired breath, assisting formation of warmed humidified such portions to include in such inspiration breath;
k) at least one carbon dioxide adsorber adapted to adsorb carbon dioxide from such cooled, de-humidified expired breath;
l) at least one further cooler adapted to further cool such cooled, de-humidified expired breath;
m) at least one extraterrestrial body suit adapted to extraterrestrial body protection; and
n) at least one suit cooler adapted to cool body-heat suit warming;
