Crew Unloads Dragon as Russian Cargo Ships Depart, Prep for Launch


ISS — Expedition 60 Mission patch.


July 29, 2019


A new U.S. space freighter is open for business today after delivering its payload to the International Space Station on Saturday. Meanwhile, a Russian resupply rocket is processing for another space delivery mission on Wednesday that will take less than three and a half hours after launch.


NASA Flight Engineer Nick Hague opened Dragon’s hatch early Sunday beginning a month of cargo operations. His fellow crewmates Christina Koch and Andrew Morgan are unloading critical research samples and stowing them inside the station’s science freezers and incubators for analysis.

The new experiments will be exploring microgravity’s effect on a variety of biological and physical processes benefitting humans on Earth and in space. The crew will be researching 3-D bio-printing, silica manufacturing, botany and tissue regeneration and a host of other space phenomena.

Robotics controllers will remove the International Docking Adapter-3 (IDA-3), a new commercial crew ship docking port, from Dragon’s unpressurized trunk in mid-August. A pair of spacewalkers will install the IDA-3 on the Harmony module’s space-facing Pressurized Mating Adapter a few days later.


Russia’s Pirs Docking Compartment port opened up today at 6:44 a.m. EDT when the Progress 72 (72P) cargo craft undocked completing a four-month stay at the orbiting lab. It will re-enter the Earth’s atmosphere loaded with trash and discarded gear for a fiery, but safe disposal over the Pacific Ocean.

The new Progress 73 cargo ship will replace 72P after it launches Wednesday at 8:10 a.m. from the Baikonur Cosmodrome in Kazakhstan. It will dock to Pirs that same morning at 11:35 a.m. after just two Earth orbits packed with more food, fuel and supplies for the crew.


Cosmonauts Alexey Ovchinin and Alexander Skvortsov are training today on the tele-robotically operated rendezvous unit (TORU) for Wednesday’s arrival of the 73P. The duo will be in the Zvezda service module at the controls of the TORU monitoring the 73P’s approach ready to take over manual docking operations in the unlikely event of an emergency.
