The Animal Module for Autonomous space Support (A-MASS) provides 30-day autonomous care for mice in space. This novel system successfully overcame technical and animal welfare challenges for future space missions.

Area of Science:

  • Space biology and engineering
  • Animal welfare in microgravity research

Background:

  • No existing space hardware supported mice autonomously for extended durations.
  • Previous space missions required significant astronaut intervention for animal care.

Purpose of the Study:

  • To develop and test the Animal Module for Autonomous space Support (A-MASS) for 30-day mouse spaceflight.
  • To address technical and animal care challenges in a limited payload volume.

Main Methods:

  • Incorporated sensors, video, oxygen supply, and data logging within a 42.5L volume.
  • Designed for autonomous maintenance of temperature, humidity, food, water, and air quality.
  • Implemented waste removal and ensured clear camera view for monitoring.

Main Results:

  • A-MASS met all NIH guidelines for environmental parameters and animal support.
  • The module passed rigorous animal health, vibrational, mechanical, and electrical testing.
  • Successfully demonstrated autonomous support for mice over 30 days.

Conclusions:

  • The A-MASS design successfully addressed critical technical and animal care challenges for spaceflight.
  • The gathered data is applicable for developing future mouse habitats on the Space Station and other platforms.
  • Paved the way for extended autonomous animal research in space environments.
