SpaceX’s Dragon cargo spacecraft splashed down at 3:05 p.m. EDT Sunday, May 18, 2014 in the Pacific Ocean, approximately 300 miles west of Baja California, returning more than 3,500 pounds of NASA cargo and science samples from the International Space Station.
Investigations included among the returned cargo could aid in better understanding the decreased effectiveness of antibiotics during spaceflight while also improving antibiotic development on Earth. Others could lead to the development of plants better suited for space and improvements in sustainable agriculture.
The T-Cell Activation in Aging experiment, which also launched to space aboard Dragon, seeks the cause of a depression in the human immune system while in microgravity. The research could help researchers develop better protective measures to prevent disease in astronauts.
