The crew retrieved samplers as part of the Aerosol Sampling Experiment that had been deployed the day before in Nodes 1 and 3. After connecting them to chargers, they were redeployed for a second round of sampling. The battery-powered samplers pull in air and collect particles through thermophoresis, a process in which different particle types exhibit different responses to the force of a temperature gradient. The collected cabin air particles are later returned to Earth so investigators can study them with powerful microscopes.
The Veggie facility amped up production with an additional six space algae culture bags installed by the astronauts for future studies. The Space Algae investigation will further NASA’s understanding of how plants respond and grow in spaceflight using state-of-the-art omics approaches. Algae may perceive microgravity as a physical stress, which can trigger the production of high-value compounds. Scientists plan to sequence whole genomes of the space-grown algal populations to identify genes related to growth in spaceflight and evaluate how their composition changes in low-Earth orbit.
In addition, the crew continued the organization, packing and loading of items slated for return on SpaceX’s Dragon early next month.

The crew also completed routine eye checks with an ultrasound device Wednesday morning to maintain good vision during spaceflight.
Russia’s Progress 70 (70P) cargo craft delivered nearly 5,700 pounds of crew supplies and station cargo to the International Space Station on Monday less than four hours after launch. Meanwhile, the U.S. Cygnus resupply ship from Northrop Grumman tested its ability to boost the orbital laboratory’s altitude today.
Monday’s arrival of the Russian resupply craft set a milestone for station operations by arriving with its cargo in just 3 hours and 40 minutes, or only two Earth orbits. The new Progress makes six spacecraft parked at the orbital complex including the Progress 69 resupply ship, the Soyuz MS-08 and MS-09 crew ships and the SpaceX Dragon and Northrop Grumman Cygnus space freighters.
The engine on Northrup Grumman’s Cygnus cargo ship fired for 50 seconds Tuesday at 4:25 p.m. EDT to reboost the station in a test designed to verify an additional capability to adjust the station’s altitude, if required. The brief engine firing raised the station’s altitude by about 295 feet. Cygnus will depart the station on Sunday after delivering several tons of supplies and science experiments back in May for the six crewmembers on board.
Traveling about 250 miles over the Tasman Sea between Australia and New Zealand, the unpiloted Russian Progress 70 cargo ship docked at 9:31 p.m. EDT to the Pirs Docking Compartment of the International Space Station.
