Space station captures Dragon capsule for second time, making history

Following its successful launch from the Kennedy Space Center in Florida on Saturday, June 3, SpaceX’s Dragon capsule made history on Monday, June 5 as it became the company’s first spacecraft to connect with the International Space Station (ISS) for a second time.

Its arrival makes it the first U.S. spaceship to return to the ISS since the space shuttle program ended in 2011.

The Dragon first visited the space station in 2014, with this second trip serving to highlight the progress SpaceX is making with the design of its reusable rocket system, which also includes a Falcon 9 launch vehicle capable of landing back on Earth minutes after leaving the ground.

NASA announced the historic revisit by the uncrewed Dragon on its website: “While the International Space Station was traveling about 250 miles over the south Atlantic ocean east of the coast of Argentina, flight engineers Jack Fischer and Peggy Whitson of NASA captured Dragon (below) a few minutes ahead of schedule at 9:52 a.m. ET.”

Now that it’s in the firm grip of the inhabited orbiting satellite, the Dragon cargo ship will be carefully maneuvered by ground crew using the space station’s robotic arm. They’ll carefully install the capsule onto the Earth-facing port of the Harmony module before the astronauts begin unpacking nearly three tons of supplies and equipment.

The science gear includes, of all things, a number of fruit flies for an experiment aimed at improving our understanding of the effects on the heart of lengthy exposure to microgravity. “Because they’re small, age rapidly, and have a well-known genetic make-up, [the flies] are good models for heart function studies,” NASA explained.

The crew will also be conducting tests focusing on osteoporosis as scientists search for ways to help astronauts maintain bone density when in space for extended periods. If the research proves successful, the findings could lead to the creation of medication that can prevent bone loss and even build new bone, helping not only astronauts on future missions into deep space but also millions of people back on Earth currently dealing with the condition.

In addition, three payloads inside Dragon’s unpressurized area will demonstrate new solar panel technologies, study the physics of neutron stars, and host an array of Earth-viewing instruments, NASA said.

The Dragon will stay docked for the rest of this month before SpaceX embarks on its next challenge — bringing it back safely to Earth, where it it is hoped that it will splash into the Pacific Ocean off the coast of Baja California. And after that? Another trip to the space station with more supplies, most likely.
