HOUSTON (NASA PR) — SpaceX’s Dragon cargo ship splashed down off the coast of Baja California this morning with more than 4,100 pounds of NASA cargo, science and technology demonstration samples from the International Space Station.
The Dragon spacecraft will be taken by ship to Long Beach, where some cargo will be removed immediately for return to NASA. Dragon then will be prepared for a return trip to SpaceX’s test facility in McGregor, Texas, for final processing.
A variety of technological and biological studies are returning in Dragon. The Fruit Fly Lab-02 experiment seeks to better understand the effects of prolonged exposure to microgravity on the heart. Flies are small, with a well-known genetic make-up, and age rapidly, making them good models for heart function studies. This experiment could significantly advance understanding of how spaceflight affects the cardiovascular system and could help develop countermeasures to help astronauts.
Samples from the Systemic Therapy of NELL-1 for osteoporosis will return as part of an investigation using rodents as models to test a new drug that can both rebuild bone and block further bone loss, improving crew health. When people and animals spend extended periods of time in space, they experience bone density loss, or osteoporosis. In-flight countermeasures, such as exercise, prevent it from getting worse, but there isn’t a therapy on Earth or in space that can restore bone density. The results from this ISS National Laboratory-sponsored investigation is built on previous research also supported by the National Institutes for Health and could lead to new drugs for treating bone density loss in millions of people on Earth.
The Cardiac Stem Cells experiment investigated how microgravity affects stem cells and the factors that govern stem cell activity. The study focuses on understanding cardiac stem cell function, which has numerous biomedical and commercial applications. Scientists will also look to apply new knowledge to the design of new stem cell therapies to treat heart disease on Earth.
Dragon is the only space station resupply spacecraft able to return a significant amount of cargo to Earth. The spacecraft lifted off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on June 3 carrying about 6,000 pounds of supplies and scientific cargo on the company’s eleventh commercial resupply mission to the station.
For more than 16 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 2,000 research investigations from researchers in more than 95 countries.
