Another Dragon, Another EVA for ISS

June was pretty busy for the crew of Expedition 56. With all of the maintenance and experiments performed by the six-person crew, you'd think they were busy enough! But no, they also had to prepare for a spacewalk and to make preparations for a new Dragon Cargo ship. On June 14, astronauts Drew Feustel (Expedition 56 commander) and Ricky Arnold (flight engineer) performed a6 hour 49 minute EVA to install improved HD camera equipment on the outside of the station.

The two spacewalkers  installed the HD cameras to help improve the view of the upcoming Dragon crewed ship docking and future Boeing Starliner crew vehicle dockings. In addition to the cameras, they moved some grab handles and performed some maintenance outside the Japanese KIBO module.

Following liftoff on Friday, and a three-day orbital chase, another Dragon cargo ship arrived at the ISS and was captured by robotic arm on Monday July 2. Astronauts Ricky Arnold, backed up by Drew Feustel, maneuvered the craft to dock at the US-built Harmony module. It carried science equipment, supplies, and biological experiments. Dragon is scheduled to stay at the station for about a month.
Parking is getting pretty limited up there.
 
With the arrival of Dragon, the ISS ports look pretty full. There are two Soyuz crew vehicles, a Cygnus cargo ship, a Dragon cargo ship, a Russian Progress cargo ship, and the inflatable Bigelow BEAM module attached to docking ports. Soon, however, we can expect further US-built crew ships (Dragon2 and Boeing Starliner) to be arriving for testing. This will make parking very interesting at the ISS!
