The large box on the right is supporting a biotechnology study that looks at microalgae as a sustainable source for oxygen in spacecraft life support systems. The smaller box on the left provides a platform to test data processing and algorithms in microgravity.

The Artemis III spacesuit prototype, the AxEMU. Though this prototype uses a dark gray cover material, the final version will likely be all-white when worn by NASA astronauts on the Moon’s surface, to help keep the astronauts safe and cool while working in the harsh environment of space.
