<\/a>While the International Space Station<\/a> was traveling over the Pacific Ocean, a SpaceX Dragon cargo spacecraft autonomously docked to the space-facing port of the station\u2019s Harmony module at 7:39 a.m. EST, with NASA astronauts Nicole Mann<\/a> and Josh Cassada<\/a> monitoring operations from the station.<\/p>\n The Dragon launched on SpaceX\u2019s 26th contracted commercial resupply mission for NASA at 2:20 p.m. EST, Saturday, Nov. 26, from Launch Complex 39A at the agency\u2019s Kennedy Space Center in Florida. After Dragon spends about one month attached to the space station, the spacecraft will return to Earth with cargo and research.<\/p>\n Among the science experiments Dragon is delivering to the space station are:<\/p>\n Big Hopes for Small Tomatoes<\/strong><\/p>\n A continuous source of nutritious food is essential for long-duration exploration missions, and the typical pre-packaged astronaut diet may need to be supplemented by fresh foods produced in space. Researchers have been testing a plant growth unit on station known as Veggie<\/strong><\/a> and have successfully grown a variety of leafy greens. Veg-05<\/strong><\/a>, the next step in that work, focuses on growing dwarf tomatoes.<\/p>\n Picture of Health<\/strong><\/p>\n Moon Microscope<\/strong><\/a> tests a kit for in-flight medical diagnosis that includes a portable hand-held microscope and a small self-contained blood sample staining device. An astronaut collects and stains a blood sample, obtains images with the microscope, and transmits images to the ground, where flight surgeons use them to diagnose illness and prescribe treatment.<\/p>\n The kit could provide diagnostic capabilities for crew members in space or on the surface of the Moon or Mars, as well as the ability to test water, food, and surfaces for contamination. The hardware also may enable improved medical monitoring on upcoming Artemis and Gateway missions.<\/p>\n Building Bigger Structures<\/strong><\/p>\n On Earth, gravity deforms large objects such as the beams used in large-scale construction. Microgravity enables fabrication of longer and thinner structures without this deformation. Extrusion<\/strong><\/a> demonstrates a technology using liquid resin to create shapes and forms that cannot be created on Earth. Photocurable resin, which uses light to harden the material into its final form, is injected into pre-made flexible forms and a camera captures footage of the process. The capability for using these forms could enable in-space construction of structures such as space stations, solar arrays, and equipment.<\/p>\n The Space Exploration Initiative<\/strong><\/a> supports a range of microgravity and lunar research across science, engineering, art, and design. The experiment is packed inside a Nanoracks Black Box with several other experiments from the Massachussetts Institute of Technology Media Lab and is sponsored by the ISS National Lab<\/strong><\/a>.<\/p>\n On-Demand Nutrients<\/strong><\/p>\n Supplying adequate nutrition is a major challenge to maintaining crew health on future long-duration space missions. Many vitamins, nutrients, and pharmaceuticals have limited shelf-life, and the ability to make such compounds on-demand could help maintain crew health and well-being. BioNutrients-2<\/strong><\/a> tests a system for producing key nutrients from yogurt, a fermented milk product known as kefir, and a yeast-based beverage.<\/p>\n The investigation kicks off phase two of the five-year BioNutrients<\/strong><\/a> program, headed by NASA\u2019s Ames Research Center and managed by Game Changing Development in NASA\u2019s Space Technology Mission Directorate. The program began with the launch of BioNutrients-1<\/strong><\/a> in 2019. BioNutrients-2 employs a smaller system with a heated incubator that promotes growth of beneficial organisms.<\/p>\n The researchers also are working to find efficient ways to use local resources to make bulk products such as plastics, construction binders, and feedstock chemicals. Such technologies are designed to reduce launch costs and increase self-sufficiency, extending the horizons of human exploration.<\/p>\n Adding Solar Power<\/strong><\/p>\n Two International Space Station Roll-Out Solar Arrays, or iROSAs, launched aboard SpaceX\u2019s 22nd commercial resupply mission for the agency and were installed in 2021. These solar panels, which roll out using stored kinetic energy, expand<\/strong><\/a> the energy-production capabilities of the space station. The second set launching in the Dragon\u2019s trunk once installed, will be a part of the overall plan to provide a 20% to 30% increase in power for space station research and operations.<\/p>\n These arrays, the second of three packages, will complete the upgrade of half the station\u2019s power channels. iROSA technology was first tested<\/strong><\/a> on the space station in 2017. Roll-out solar array technology was used on NASA\u2019s Double Asteroid Redirection Test mission and is planned for use on the Gateway<\/strong><\/a> lunar space station, a vital component of NASA\u2019s Artemis program. The iROSA upgrades use the space station as a proving ground for the technology and research needed to explore farther into space.<\/p>\n Easing Gravity Transitions<\/strong><\/p>\n Travelers to space all face the transition from one gravity field to another. On future exploration missions, astronauts may encounter three different gravity fields: weightlessness while traveling in space, the gravity of another planet, and Earth\u2019s gravity when they return. These transitions can affect spatial orientation, head-eye and hand-eye coordination, balance, and locomotion, and cause some crew members to experience space motion sickness.<\/p>\n The Falcon Goggles hardware captures high-speed video of a subject\u2019s eyes, providing precise data on ocular alignment and balance.<\/p>\n These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the\u202fMoon and Mars<\/a>\u202fthrough NASA\u2019s\u202fArtemis<\/a>\u202fmissions.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
