NASA and SpaceX are targeting a mid-May launch to deliver scientific investigations, supplies, and equipment to the International Space Station. 
Loaded with about 6,500 pounds of supplies, the SpaceX Dragon spacecraft will lift off aboard the company’s Falcon 9 rocket from Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Following its arrival to the orbital complex, Dragon will dock autonomously to the forward port of the space station’s Harmony module.

For more than 25 years, the International Space Station has provided research capabilities used by scientists from more than 110 countries to conduct more than 4,000 experiments in microgravity. Research conducted aboard the station helps advance long-duration missions to the Moon as part of the Artemis program and to Mars, while providing multiple benefits to humanity. 
In addition to cargo for the crew aboard the space station, Dragon will deliver several new science experiments, including: 
ODYSSEY will evaluate how well Earth-based microgravity simulators recreate space conditions. Researchers will examine bacterial behavior in space and compares the results to experiments conducted in microgravity simulators on Earth. 
STORIE will monitor charged particles in orbit around the Earth, which respond to space weather and can affect assets like power grids and satellites. The instrument could help researchers gain knowledge to better predict and respond to these changes. 
Laplace will study the movement and collision of dust particles in microgravity to understand particle motion in space. Researchers hope to learn more about Earth’s origins and provide fundamental understanding of how planets in our solar system and beyond came into existence. 
Green Bone will observe how bone cells grow and develop in space on a bone scaffold made from wood. Microgravity results could help researchers improve products that treat fragile bone conditions such as osteoporosis. 
SPARK will evaluate how red blood cells and the spleen change in space for future astronauts. Researchers will observe human samples and imagery taken before, during, and after spaceflight to identify ways to protect astronaut health during long-duration space missions.  
NASA astronaut Jack Hathaway and ESA (European Space Agency) astronaut Sophie Adenot will monitor the spacecraft’s arrival. Dragon will remain docked to the orbiting laboratory for about a month before splashing down in the Pacific Ocean, returning critical science and hardware to teams on Earth. 
European Enhanced Exploration Exercise Device Power Cable – A replacement power cable is launching for installation on the European Enhanced Exploration Exercise Device.  
Catalytic Reactor – A vital component of the Water Recovery and Management System, the catalytic reactor oxidizes volatile organics from wastewater that are removed by the Gas Separator and Ion Exchange Bed orbital replacement units. This part is launching to maintain on orbit sparing.  
Universal Pretreat Concentrate Tank – This is a passive tank to provide alternate pretreat concentrate to the Universal Waste Management System (UWMS) and Waste Hygiene Compartment (WHC). Two units are launching to maintain this hardware, in tandem with Russian pretreat tanks currently used. A universal pretreat concentrate tank adapter will accompany the tanks to connect with the Russian hose.  
Additional equipment launching includes an Ultraprobe to replace a worn ultrasonic inspection tool, a Remote Sensor Unit to restore spares for the station’s vibration monitoring system, and flexible repair patches for sealing the pressure hull if needed. The mission also will deliver an updated ARMADILLO (AOGA ReMediation, Advanced DeIonization and Limited Life Optimization) cartridge and hose assemblies to improve water processing for oxygen generation, along with a nitrogen recharge tank assembly to help maintain the station’s gas reserves. 
When Dragon returns in mid‑June, it will bring back an ocular imaging device used to monitor crew eye health, a sorbent bed that filters trace contaminants from cabin air, and a separator pump from the Waste and Hygiene Compartment. The Advanced Plant Habitat, which supported long-duration plant biology studies, also will return for eventual museum display. A pressure management device that recovers vestibule air during depressurization will come back for repair and storage as a ground spare.  
NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.
