August Brings More Spaceship Traffic and a Spacewalk


ISS — Expedition 60 Mission patch.


August 1, 2019


The International Space Station is hosting five spaceships today as August ramps up for more orbital traffic activity. Six Expedition 60 crewmembers are also unloading U.S. and Russian cargo, activating new science experiments and stocking the station’s galley.


Russia’s Progress 73 (73P) cargo craft completed a fast-track delivery mission early Wednesday docking to the Pirs Docking Compartment just three hours and nineteen minutes after launching from Kazakhstan. Cosmonaut Alexander Skvortsov opened the 73P hatch shortly afterward starting its four-month stay. He and station Commander Alexey Ovchinin then began unloading nearly three tons of new consumables, fuel and supplies.

Two U.S. space freighters occupy the station’s Earth-facing Harmony and Unity module ports. Harmony will open up Tuesday when Northrop Grumman’s Cygnus resupply ship departs after 109 days in space. The Canadarm2 robotic arm installed the SpaceX Dragon to Unity on Saturday after its arrival and capture beginning a month of cargo operations.


NASA astronauts Christina Koch and Nick Hague are tending to mice today shipped aboard Dragon for ongoing biological research. The reusable vehicle will return the mice back to Earth at the end of the month, including other cargo, so scientists can analyze a variety of changes that only occur in microgravity.

Dragon also delivered a new commercial crew vehicle port, the International Docking Adapter-3 (IDA-3), in its unpressurized trunk. Robotics controllers will soon extract the IDA-3 before two spacewalkers install it to Unity’s space-facing port a few days later.


A few days before Dragon departs, Russia will launch an unpiloted Soyuz MS-14 crew ship to the orbiting lab for a test of its upgraded 2.1a Soyuz booster. It will dock to the Poisk module for a two-week stay before parachuting back to Earth in the vast steppe of Kazakhstan.
