ISS Science for Everyone

Science Objectives for Everyone
Space Tango Payload Card MMARS-1 (MMARS-1) is a commercial experiment led by Airbus DS in collaboration with its scientific partners the International Space University and the University of Strasbourg. The purpose of this experiment is to study how a strain of methanogen (methane producing bacteria), Methanosarcina barkeri (M. barkeri), adapts to the stresses of the space environment. Specifically, MMARS-1 demonstrates the use of pressure measurements to estimate metabolic activity of M. barkeri. The overall experimental approach investigates the decoupling of metabolic activity from biomass production, and studies the growth of M. barkeri using liquid medium under microgravity conditions.

Experiment Description

Research Overview

The purpose of this experiment is to study how a strain of methane producing bacteria, Methanosarcina barkeri (M. barkeri), adapts to the stresses of the space environment, including microgravity and radiation, as a first step towards further studies related to relevant non-early applications of methanogens.

Description

The purpose of this experiment is to study how a strain of methanogen, Methanosarcina barkeri, adapts to the stresses of the space environment, including microgravity and radiation, as a first step towards further studies related to relevant non-early applications of methanogen. Specifically, the goals of the MMARS-1 experiment include:
  1. To demonstrate the use or pressure measurements to estimate metabolic activity of M. barkeri and the overall experimental approach;
  2. Investigate the decoupling of metabolic activity from biomass production;
  3. Study the growth of M. barkeri using liquid medium, including time of lag phase, growth rate, and time to stationary phase change under conditions of space flight.

Applications

Space Applications
The Space Application for this investigation has yet to be identified.

Earth Applications

Methanogens, such as M. barkeri, make methane from carbon dioxide and hydrogen gases. M. barkeri can be found in many waste environments (i.e. landfills) as well as digestive systems of both humans and animals. The study of methanogens could have an impact on waste treatment, biological digestion, and alternative fuel sources.

Operations

Operational Requirements and Protocols
The science is contained in a 2U CubeLab attached to a Payload Card for soft-stow ascent, operates in the TangoLab-1, and is soft-stowed for return. The crew installs the Payload Card into the TangoLab-1, where autonomous operations occur, and then the crew removes and stows the hardware for return. The Payload Card is returned after the completion of the mission on the next available return vehicle (same vehicle as ascent is preferred) and turned over to the Space Tango/PI team at recovery.
