The 22nd SpaceX Freight Supply Mission, which will carry out scientific research and technology demonstrations, will be launched from NASA’s Kennedy Space Center in Florida to the International Space Station by June 3. Kidney stones, etc.
The highlights of the payload of this supply mission are:
Tardigrades occupy the universe
Known as the tardigrade Tardigrade Due to its microscopic appearance and common underwater habitat, it is a small creature that withstands more extreme environments than most living organisms.It makes them model organisms for studying biological survival on Earth and under extreme conditions on Earth. space.. In addition, researchers have developed a method for sequencing the tardigrade Hypsibius exemplaris genome and measuring how different environmental conditions affect tardigrade gene expression. Cell Science-04 characterizes the molecular biology of tardigrade short-term and multigenerational survival and identifies genes involved in adaptation and survival in high-stress environments.
The results may help us better understand the stressors that affect humans in space and support the development of countermeasures. “Space flight can be a truly challenging environment for living things, including humans, who have evolved into the state of the Earth,” says Senior Researcher Thomas Boothby. “One of the things we really want to do is to learn something about how tardigrades survive and breed in these environments, and the tricks they use, and to protect astronauts. It’s about understanding if they can be adapted. “
Symbiotic squid and microorganisms under microgravity
Umami examines the effects of space flight on molecular and chemical interactions between beneficial microorganisms and their animal hosts.Microorganisms play an important role in the normal development and maintenance of animal tissue Human health.. “Animals, including humans, rely on our microbes to maintain a healthy digestive system. Immune system“We don’t fully understand how spaceflight alters these beneficial interactions,” said Jamie Foster, a senior researcher at UMAMI. In umami experiments, we used dango squid that glowed in the dark. , Addressing these important issues in animal health. “
Dango squid, dango squid, is an animal model used to study the symbiotic relationship between two species. This study will help determine if space flight changes mutually beneficial relationships. This may support the development of protective and mitigation measures to maintain the health of astronauts on long-term space missions. This study may also lead to a better understanding of the complex interactions between animals and beneficial microorganisms, including new new pathways that microorganisms use to communicate with animal tissues. Such knowledge can help identify ways to protect and strengthen these relationships for better human health and well-being on Earth.
Butterfly IQ Ultrasound demonstrates the use of portable ultrasound in combination with mobile computing devices under microgravity. This study collects crew feedback on the ease and quality of ultrasound images, including image acquisition, display, and storage.
“This type of off-the-shelf technology has the potential to provide critical medical features for future exploration missions beyond low earth orbit where immediate ground support is not available,” said Kadambari Suri, integrated manager of Butterfly iQ technology demonstrations. Stated. Also, find out how effective just-in-time instructions are for the crew to use the device autonomously. This technology could also be applied to medical care in remote, isolated environments on Earth.
Developing better robot drivers
A study by the ESA (European Space Agency) and the French National Center for Space Studies (CNES), pilots use virtual reality and tactile interfaces, or simulated touch and motion to remote robotic arms and spacecraft. Test the effectiveness of the operation. Ergonomic tests for controlling robot arms and spacecraft should be performed in microgravity. This is because the design of Earth-based tests uses ergonomic principles that do not meet the conditions experienced in orbiting spacecraft. Pilote compares existing and new technologies, including recently developed technologies for remote control and those used for Canadarm2 and Soyuz spacecraft pilots. The study also compares the performance of astronauts on the ground and during long-term space missions. The results could help optimize the ergonomics of space station workstations and future spacecraft for missions to the Moon and Mars.
Protect the kidneys of space and the earth
Some crew members become more sensitive to kidney stones during flight, which can affect their health and mission success. The Kidney Cells-02 study uses a 3D kidney cell model (or tissue chip) to study the effects of microgravity on the formation of microcrystals that can lead to kidney stones. It is part of the Tissue Chips in Space initiative, a partnership between the National Institutes of Health and the National Center for Advancing Translational Sciences (NCATS), and the impact of microgravity on human health. Analyze and transform it into an improvement of the earth. .. The study reveals important pathways for the development and progression of kidney disease, which could lead to treatments for astronauts and one in ten people on the planet who develop kidney stones. There is.
“This study wants to identify biomarkers or” signatures “of cellular changes that occur during formation. Kidney stone“Senior researcher Ed Kelly said. “This could lead to new therapeutic interventions. The reason for doing this study on the space station is that crystallites behave as they occur in our own kidneys, like laboratories on Earth. In addition, the crystallites remain floating in the kidney tip tube and do not sink to the bottom. “
Production of stronger cotton
Cotton plants that overexpress certain genes are more resistant to stressors such as drought and yield 20% more cotton fiber than plants that do not have that property under certain stress conditions. This stress tolerance is tentatively associated with having a fortified root system that has access to large amounts of soil for water and nutrients. In-orbit cultivation of improved cotton targeting (TICTOC) studies how rootline structure affects plant resilience, water utilization efficiency, and carbon sequestration at key stages of sapling. Root growth patterns are gravity-dependent, and TICOC helps define which environmental factors and genes control root development in the absence of gravity.
Cotton is used in a variety of consumer products, from clothing to bed sheets to coffee filters, but the impact of its production includes the use of large amounts of water and the intensive use of pesticides. “We would like to characterize the root line formation that breeders and scientists can target to improve properties such as drought tolerance and nutrient absorption, which are important factors in the environmental impact of modern agriculture.” Said senior researcher Simon Gilroy. A better understanding of gene expression associated with cotton root systems will enable the development of stronger cotton plants and reduce the use of water and pesticides.
New solar panels are heading to the station to increase the energy available for research and other onboard activities. The ISS Rollout Solar Array (iROSA) consists of compact panels based on technology previously proven at the station and rolls open to spread long rugs. The Expedition 65 65 will begin preparations this summer to supplement the station’s existing rigid panels with the first pair of six new arrays.
