Crew Juggles Emergency Drill, Space Biology and Dragon Preps

The six-member Expedition 59 crew conducted a routine, periodic drill for response to emergencies today in the middle of a science-packed day. The astronauts also researched space biology while preparing for next week’s SpaceX Dragon cargo mission.

The space residents practiced communications, roles and responsibilities, and evacuating the station in the unlikely event of an emergency. The crew would split up, board their Soyuz spacecraft and undock quickly for a ride back to Earth. The two Soyuz crew ships docked to the International Space Station each hold three crewmembers.

NASA Flight Engineers Nick Hague and Anne McClain set up the ultrasound and optometry instruments today for more Fluid Shifts studies. Flight surgeons are exploring what happens to an astronaut’s veins and eyes due to the head-ward flow of fluids caused by microgravity.

Hague later checked out command and communications gear he and astronaut David Saint-Jacques will use when the SpaceX Dragon resupply ship arrives next week. Saint-Jacques will command the Canadarm2 robotic arm to capture Dragon early Friday, May 2, two days after it launches from Florida. Hague will monitor Dragon’s telemetry during its approach and rendezvous. NASA TV is broadcasting the pre-flight activities and mission events live.

Saint-Jacques and Flight Engineer Christina Koch also split the day feeding mice and cleaning cages for the Rodent Research-12 experiment. The study is investigating the immune system’s response to the conditions of long-term spaceflight.

Commander Oleg Kononenko focused much of his attention today on life support maintenance in the Russian segment of the orbital lab. Flight Engineer Alexey Ovchinin studied ways to maximize the effectiveness of exercise in the weightless environment of microgravity.

Biomedical and Botany Research Today as Station Preps for Sixth Spacecraft

Vein scans and eye checks were on the schedule today as the Expedition 59 crew continues ongoing biomedical studies. The International Space Station is also getting ready to host a sixth spacecraft when it arrives next week.

Scientists have been observing the space residents all week as they seek to understand the effects of the upward flow of body fluids in space. Flight Engineer Anne McClain worked on the Fluid Shifts experiment again today attaching body electrodes to NASA astronaut Nick Hague and conducting ultrasound scans of his veins. She also peered into his eyes using optical tomography coherence hardware. Results may help flight surgeons prevent the increased head and eye pressure caused by the upward fluid shifts astronauts report in space.

NASA is also learning how to support longer human missions farther out into space. Feeding crews without expensive cargo missions and fuel-consuming inventories is critical. As a result, the station provides a variety of greenhouse facilities for plant cultivation and research. Christina Koch of NASA set up new botany hardware today to enable the ongoing research and harvesting of lettuce and mizuna in space.

The SpaceX Dragon resupply ship is due to liftoff Tuesday at 4:21 a.m. EDT on its 17^th contracted cargo mission to the station. Canadian Space Agency astronaut David Saint-Jacques is training to capture Dragon with the Canadarm2 robotic arm when it arrives Thursday May 2 at 6:50 a.m. A pair of new experiments it is delivering will explore atmospheric carbon dioxide as well as X-ray frequency communication techniques.

More Head and Eye Pressure Research and Dragon Robotics Training

The Expedition 59 crew is unloading one U.S. cargo ship today and preparing for the arrival of another after it launches from Florida next week. The orbital residents also continued exploring how microgravity impacts the human body and a variety of terrestrial materials.

Astronauts Christina Koch and David Saint-Jacques worked Wednesday afternoon to offload some of the 7,600 pounds of cargo the Cygnus space freighter delivered last week. Saint-Jacques is also training today to capture the SpaceX resupply ship with the Canadarm2 robotic arm when it arrives next Thursday. Dragon will be the sixth spaceship parked at the station and occupy the Harmony module’s Earth-facing port.

The duo also split the day working with a variety of biomedical hardware and research gear to ensure healthy astronauts and successful space research. Koch and Saint-Jacques participated in ultrasound scans for ongoing health checks. Koch then explored the feasibility of manufacturing fiber optic cables in space. Saint-Jacques set up Kubik incubator hardware inside Europe’s Columbus lab module.

NASA Flight Engineers Anne McClain and Nick Hague were back collecting more blood, urine and saliva samples today. The samples are spun in a centrifuge, stowed in a science freezer then analyzed for the long-running Fluid Shifts study. The experiment seeks to understand and prevent the upward flow of body fluids in space that cause head and eye pressure in astronauts.

McClain then studied how living aboard the International Space Station affects her perception and cognition. Hague researched and photographed a variety of coating materials for their thermal protection and optical recognition properties.

Human Research, Materials Science and Robotics on Tuesday’s Schedule

The Expedition 59 crew spent the majority of Tuesday conducting space experiments and setting up research hardware. The International Space Station residents are also continuing to unpack a pair of recently arrived cargo ships while training for the next U.S. cargo mission.

The weightless conditions of microgravity pull fluids towards an astronaut’s head causing a common space phenomenon sometimes called “puffy-face.” Flight Engineer Nick Hague of NASA spent the morning collecting and stowing his blood, urine and saliva samples for the long-running Fluid Shifts study. The research observes and seeks to reverse the upward flow of fluids causing increased head and eye pressure that concerns flight surgeons.

NASA astronaut Christina Koch set up hardware in the Destiny lab module to begin researching the feasibility of manufacturing fiber optic cable in space. The Space Fibers study takes place inside the Microgravity Science Glovebox and will explore a blend of materials more transparent than silica-based glass.

A new materials exposure experiment is ready for deployment outside Japan’s Kibo lab module. NASA astronaut Anne McClain installed the MISSE-FF gear inside Kibo’s airlock before depressurizing the unit. Robotics controllers will deploy the exposed sample trays outside the airlock. The study will help scientists understand how radiation, the vacuum of space and micrometeoroids affect a variety of materials.

Canadian Space Agency astronaut David Saint-Jacques is training for his role to capture the next SpaceX Dragon cargo craft. Hague joined him today for the robotics training and will back him up in the cupola. Dragon is scheduled to launch April 30 from Florida and take a two-day trip to the station where it will be grappled with the Canadarm2 robotic arm and installed to the Harmony module.

Commander Oleg Kononenko helped attach sensors to Flight Engineer Alexey Ovchinin as the duo researched cardiovascular activity during exercise in space. Kononenko went on to replace smoke detectors as Ovchinin worked on life support maintenance.

New Life Science Begins; Next Dragon Cargo Mission Due Next Week

The Expedition 59 crew has been unpacking Northrop Grumman’s Cygnus cargo craft over the weekend and began science operations on the newly delivered space research. The 17^th SpaceX Dragon mission is now due to launch next week to replenish the International Space Station.

Three NASA astronauts and one Canadian Space Agency astronaut split the workday measuring the mass of 40 mice shipped to the station aboard Cygnus last week. Flight Engineers Anne McClain and Christina Koch started the first half of the day with Flight Engineers Nick Hague and David Saint-Jacques wrapping up the rodent research work in the afternoon. The quartet used the mass measurement device inside the Life Sciences Glovebox beginning the study to learn how microgravity impacts the immune system.

The SpaceX Dragon cargo craft is due to join the five other spacecraft parked at the station after it launches from Florida April 30. Dragon is scheduled to arrive May 2 and Saint-Jacques will command the Canadarm2 robotic arm to reach out and capture the cargo vessel. Dragon will deliver over 5,000 pounds of new science, supplies and hardware to the orbital lab.

Cosmonauts Oleg Kononenko and Alexey Ovchinin stayed focused on the Russian side of the station with their complement of orbital science and lab maintenance. Commander Kononenko updated communications gear, cleaned fans and filters and explored enzyme behaviors. Flight Engineer Ovchinin offloaded cargo from the new Progress 72 resupply ship and studied radiation exposure.
