Cooling to tempeatures in the millikelvin range could be beneficial as a means of reducing noise and increasing sensitivity of instruments in certain experiments and measurements that are being considered for future space missions. The possibility of using a He3-He4 dilution refrigerator for the purpose is explored in this paper. Calculations reported here indicate that electrostriction can be substituted for gravity as a practical means of achieving phase separation with well-defined interfaces in mixing chambers of dilution refrigerators operating aboard spacecraftt.
