“Dragon will carry back to Earth more than 4,100 pounds (1,860 kilograms) of supplies and scientific experiments designed to take advantage of the space station’s microgravity environment,” NASA officials wrote in an update on Friday (April 26).
“Splashing down off the coast of Florida enables quick transportation of the experiments to NASA’s Space Systems Processing Facility at Kennedy Space Center in Florida, allowing researchers to collect data with minimal sample exposure to Earth’s gravity,” they added.
Dragon is the only cargo craft capable of bringing gear home safely from the ISS. The other two currently operational space freighters, Russia’s Progress vehicle and Northrop Grumman’s Cygnus spacecraft, burn up in Earth’s atmosphere when their work in orbit is done.
