Fig. 1: Hardware and environmental measurements for the second JAXA mouse mission

From: Dietary intervention of mice using an improved Multiple Artificial-gravity Research System (MARS) under artificial 1 g

a Upper: a habitat cage unit (HCU) used in the first (left) and the second (right) JAXA mouse missions. Red arrows indicate the paper sheet covers. Middle: design of the paper sheet covers was modified to protect from tearing by mice. Lower; an improved transportation cage unit (TCU). be Environmental data. Temperature b and humidity c in the TCU and the HCU were recorded by data loggers. b Changes in temperature in the TCU and each cage of the HCU during the mission are shown. c changes in humidity in the TCU (orange) and microgravity (MG, in blue) and artificial 1 g gravity (AG, in yellow) sections of the HCU during the mission are shown. Gas concentration of carbon dioxide d and ammonia e in the Centrifuge-equipped Biological Experiment Facility (CBEF) were monitored as described previously1 and those in the MG (blue) and the AG (yellow) sections of the CBEF during the mission are shown
