iss067e000403 (3/31/2022) --- A view of a Cube containing Space Tango - Cubelab Satellite Demonstrator, part of TangoLab Mission-25 aboard the International Space Station (ISS). Space Tango - University of Kentucky Cubelab Satellite Demonstrator (Space Tango - Cubelab Satellite Demonstrator) tests a new attitude-control technology for small satellites, which is an integral part of future space missions.

iss067e000391 (3/31/2022) --- A Nona Cube containing Optical Imaging of Bubble Dynamics on Nanostructured Surfaces, part of TangoLab Mission-25. The Optical Imaging of Bubble Dynamics on Nanostructured Surfaces investigation observes thermal bubbles in a microgravity environment with the use of an optical imaging system.

iss067e000376 (3/31/2022) --- A Higher Orbits Double Cube aboard the International Space Station (ISS). The Effects of Microgravity on Oxygen Output Regarding Chlorella vulgaris (Oxygen Production in Algae) investigates how microgravity affects the oxygen output of an algal species. Results could improve understanding of microgravity’s effects on the process of photosynthesis and development of photosynthetic organisms, which could contribute to design of oxygen production systems for future space travel.

iss066e098812 (12/30/2021) --- A view during installation of the Cytoskeleton experiment containers installed on the BIOLAB Rotor during Expedition 66. This investigation helps to understand the way in which the human body responds to microgravity, which could feed into the development of future countermeasures to help maintain an optimal level of crew member health and performance.
