The crew is operating for several biological experiments recently launched on NASA's 32nd SpaceX Commercial Resupply Service mission. These include examining how trace gravity affects protein production through microalgae, testing microscopes to capture microbial activity, and studying genetic activity in biofilms.
This ice cream is one of several protein powders made by researchers for elastic studies by researchers, and it examines whether the stress of microgravity affects protein yields in algae. Microalgae are nutrient-intensive and produce proteins with essential amino acids, beneficial fatty acids, B vitamins, iron and fiber. These organisms can also be used to make fuels, edible oils, medicines and materials. Learn more about microalgae growth and protein production in space can support the development of sustainable alternatives to meat and dairy. This alternative could provide food sources for future space navigation and people on Earth and be used to make biofuels and bioactive compounds in medicines.
These swimming microalgae are visible due to the existing lifespan volume imaging system or Elvis, a fluorescence 3D imaging microscope that researchers are testing on the International Space Station. The study examined the active behavior and genetic changes of microscopic algae and marine bacteria in response to space flight. Elvis aims to autonomously capture microscopic motion in 3D, a feature currently available on stations. This technology may be useful for various studies in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms.
Images before this flight show the sample chamber for genetic exchange in a biofilm biorepair (GEM-B2) study that examines the mechanisms of gene transfer in biofilm under microgravity conditions. Biofilms are microbial communities that collect and bind to surfaces. They can clog and sewage systems, often leaving residues that can cause infection and may be resistant to antibiotics. Researchers can use the results of this work to develop genetic operations that inhibit biofilm formation, thereby helping to maintain the health and safety of crew members of the International Space Station and future missions.
