[b]SpaceX CRS-25 Mission Overview[/b] A SpaceX Falcon 9 rocket will launch the CRS-25 Dragon spacecraft to deliver cargo to and from the International Space Station for NASA. The fifth flight under NASA's Commercial Resupply Services-2 contract with SpaceX, the CRS-25 Dragon will carry research, logistics and hardware for the Expedition 67 crew including: [list][*]The Earth Surface Mineral Dust Source Investigation (EMIT), a study that employs NASA imaging spectroscopy technology to measure the mineral composition of dust in Earth's arid regions. Mineral dust blown into the air can travel significant distances and have impact Earth’s climate, weather, vegetation and more. [*]Immunosenescence, an investigation sponsored by ISS National Lab that uses tissue chips to study how microgravity affects immune function during flight and whether immune cells recover post-flight. Tissue chips are small devices that contain human cells in a 3D structure, allowing scientists to test how those cells respond to stresses, drugs, and genetic changes. [*]Suture In Space, an investigation from the European Space Agency (ESA) that examines the behavior of sutures and wound healing in microgravity. A better understanding of the role of mechanical forces (such as tension, stretching, and compression) in the healing of sutured wounds could help determine requirements for suturing materials and techniques suitable for future space missions to the moon and Mars. [*]DynaMoS, sponsored by NASA’s Division of Biological and Physical Sciences (BPS), will examine how microgravity affects metabolic interactions in communities of soil microbes. This research focuses on microbe communities that decompose chitin, a natural carbon polymer on Earth. [*]Genes in Space-9, sponsored by the ISS National Lab, will demonstrate cell-free production of protein in microgravity and evaluates two cell-free biosensors that can detect specific target molecules. This technology could provide a simple, portable, and low-cost tool for medical diagnostics, on-demand production of medicine and vaccines, and environmental monitoring on future space missions. [*]Biopolymer Research for In-Situ Capabilities will look at how microgravity affects the process of creating a concrete alternative made with an organic material and on-site materials such as lunar or Martian dust, known as a biopolymer soil composite (BPC). Using resources available where construction takes place makes it possible to increase the mass of the construction material and, therefore, the amount of shielding.[/list] The Falcon 9 first stage booster (B1067) supporting this mission is making its fifth launch after earlier being used for the CRS-22, Crew-3, Türksat 5B and Crew-4 missions. Following stage separation, SpaceX will attempt to recover the rocket's first stage on an autonomous drone ship in the Atlantic Ocean. The CRS-25 Dragon previously supported SpaceX's 21st and 23rd resupply services missions. The CRS-25 Dragon will return to Earth with research and cargo after spending about four weeks at the space station.
