I-HAB module (Credit: ESA)
I-HAB, a seldom-discussed component of the Lunar Gateway, could have an out-sized impact on the advancement of life support systems. This module is chiefly devoted to human habitation and life support. It is being developed primarily under the auspices of the European Space Agency who has devoted significant resources towards the development of closed-loop life support. Therefore, discussion of this module deserves to be revisited.
