Astronauts Work Science, Spacewalk Preps as Cosmonauts Relax

The Expedition 65 astronauts researched space biology while preparing for a pair of spacewalks aboard the International Space Station today. The station’s two cosmonauts cleared their schedules and relaxed aboard the orbital lab today.

Flight Engineers Shane Kimbrough and Thomas Pesquet spent part of Monday getting ready for a spacewalk set to begin Wednesday at 8 a.m. EDT. The duo configured tools, printed checklists and inspected their spacesuit jetpacks, also known as Simplified Aid for EVA Rescue (SAFER).

The duo will spend about six-and-half hours installing the first two of six new solar arrays on the space station’s integrated truss structure. The solar arrays will roll out instead of unfurling, like the older arrays, and augment the station’s power system. NASA TV will begin its live coverage of the spacewalk activities at 6:30 a.m.

The pair also had time for pharmaceutical and botany research. Kimbrough serviced samples for a study that seeks to improve the chemical and physical stability of medicine on Earth and in space. Pesquet started the Advanced Plant Experiment-07 investigation which is exploring how microgravity affects gene expression in plants.

NASA Flight Engineer Megan McArthur was looking at new ways to produce high-quality protein crystals which could lead to new disease therapies on Earth. Her fellow NASA astronaut Mark Vande Hei swapped fuel bottles inside the Combustion Integrated Rack. The duo wrapped up the day training for the Canadarm2 robotic techniques they will use to support the spacewalkers on Wednesday.

Commander Akihiko Hoshide worked on the Confocal Space Microscope then cleaned up biology hardware inside the Kibo laboratory module.

In the station’s Russian segment, cosmonauts Oleg Novitskiy and Pyotr Dubrov took the day off in space today commemorating Russia Day which observes that country’s economic and social achievements.

Space Botany and Biology Studies Under Way Benefitting Earth

Cotton plants and kidney cells were the dominant research topics aboard the International Space Station today. NASA TV will also broadcast a preview on Monday of two upcoming Expedition 65 spacewalks.

The orbiting lab is hosting a variety of life forms to help researchers understand how weightlessness affects biology. Observations provide insights often advancing health and improving conditions for humans on and off the Earth.

During Friday morning, NASA Flight Engineer Shane Kimbrough harvested cotton plants growing for the TICTOC botany study. The investigation looks at gene expression and root growth in microgravity which may improve both space agriculture and cotton cultivation on Earth.

The Kidney Cells-02 investigation is under way this week following its delivery aboard the SpaceX Crew Dragon resupply ship on Saturday. NASA astronauts Mark Vande Hei and Megan McArthur collaborated on the biotechnology study today that is seeking treatments for conditions such as kidney disease and osteoporosis affecting both astronauts and Earthlings.

Commander Akihiko Hoshide and Flight Engineer Thomas Pesquet worked on a variety of science hardware on Friday ensuring orbital research continues at full pace. Hoshide, currently on his third spaceflight, serviced medical imaging gear the crew uses regularly for eye checks. Pesquet, who is working his second station mission, stowed a small incubator after the completion of a study exploring how drugs work in space. The European Space Agency astronaut then swapped samples inside the Fluid Science Laboratory for a foam study potentially impacting consumer products, fire safety and the petroleum industry.

Kimbrough and Pesquet will go on two spacewalks set for June 16 and 20. The duo will spend six-and-half hours on both excursions installing a new pair of solar arrays robotically-extracted overnight from the Cargo Dragon’s trunk. NASA TV will go live on Monday at 2 p.m. EDT with station managers discussing the upcoming spacewalk activities to augment the station’s power system.

Over in the Russian segment of the space station, cosmonauts Oleg Novitskiy and Pyotr Dubrov worked on a variety of communications gear during the morning. After lunchtime, the duo split up to inventory cargo transferred to and from the ISS Progress 77 cargo craft and inspect the Zvezda service module.

Robotics Prepping Station for Upcoming Solar Array Spacewalks

Mission controllers will command the Canadarm2 robotic arm to remove a new pair of solar arrays from the SpaceX Cargo Dragon resupply ship tonight. Four Expedition 65 astronauts are also training for robotics activities to support two spacewalks scheduled to begin next week.

Packed inside the unpressurized segment of the Cargo Dragon, also known as its trunk, is a pair of unique solar arrays that will soon be attached to the International Space Station’s Port-6 truss structure. Also called iROSA, or ISS Roll Out Solar Arrays, they will be extracted tonight from Dragon’s trunk by robotics controllers remotely commanding the Canadarm2. It will be staged on the truss structure where two spacewalkers will install it on the station starting next week.

In the meantime, Flight Engineers Shane Kimbrough and Thomas Pesquet are preparing for those two installation spacewalks planned for June 16 and 20. The duo joined fellow flight engineers Mark Vande Hei and Megan McArthur on Thursday afternoon for computerized training to prepare for the robotics activities necessary to support the solar array installation work.

Kimbrough and Pesquet this week have been inspecting their spacesuits, organizing their tools and readying the U.S. Quest airlock where they will stage both spacewalks. They will set their spacesuit batteries to battery power at 8 a.m. EDT on both days signifying the start of their spacewalk. NASA TV will begin its live coverage of both spacewalks at 6:30 a.m.

Science is still ongoing aboard the orbital lab as the astronauts and mission controllers get ready for the two spacewalks.
