The seven-member Expedition 68 crew continued its science activities on Tuesday exploring how microgravity affects biology and physics. Back on Earth, three astronauts and one cosmonaut are less than a day away from launching to the International Space Station.

NASA Flight Engineers Frank Rubio and Bob Hines targeted their biology studies on what is happening inside the human body during spaceflight. Rubio explored how enhancing space nutrition affects the human immune and microbiome systems for the Food Physiology experiment. Hines collected his blood and urine samples and stowed them in a science freezer for later analysis. A host of space biology investigations require the samples to understand how human physiology adapts to weightlessness.

A portion of Tuesday’s space research looked at fluid physics as station Commander Samantha Cristoforetti studied how foams behave differently in space than on Earth. The ESA (European Space Agency) astronaut swapped foam samples inside the Fluid Science Laboratory for the Soft Matter Dynamics experiment.  The study may provide insights helping researchers improve materials production for Earthbound industries such as firefighting, petroleum, medicine, and food products.

Maintenance is also key on the orbital lab to ensure the space station’s many systems continuously operate in tip-top shape while orbiting an average of 260 miles above the Earth. NASA Flight Engineer Kjell Lindgren cleaned vents and fans inside the Unity module to remove impediments to the airflow. NASA astronaut Jessica Watkins worked on water transfer operations then cleaned and inspected station module hatches.

Cosmonaut Sergey Prokopyev, who is on his second spaceflight, spent Tuesday on orbital plumbing and ventilation work before configuring Earth observation hardware. First-time space flyer Dmitri Petelin of Roscosmos also spent his day on orbital plumbing duties and life support maintenance as he and Prokopyev continue to familiarize themselves with life on orbit.

Back on Earth, the SpaceX Crew-5 mission is counting down to its launch from Kennedy Space Center in Florida at noon EDT on Wednesday. Commander Nicole Mann will board the SpaceX Crew Dragon Endurance, atop the Falcon 9 rocket, with Pilot Josh Cassada and Mission Specialists Koichi Wakata and Anna Kikina then take a 29-hour ride after liftoff to the forward port on the station’s Harmony module. The commercial crew quartet will open the vehicle’s hatch and join the Expedition 68 crew shortly afterward. NASA TV will have continuous coverage of the launch, docking, and crew greeting, beginning Wednesday at 8:30 a.m. EDT on the agency’s app and website.

The next crew to the launch to the International Space Station is at the Kennedy Space Center counting down to liftoff this week. Back onboard the orbiting lab, the seven-member Expedition 68 crew is busy conducting advanced space research to improve life for humans on and off the Earth.

Four SpaceX Crew-5 crew members arrived in Florida on Saturday ahead of their launch aboard the Dragon Endurance at noon EDT on Wednesday. NASA astronauts Nicole Mann and Josh Cassada will command and pilot Endurance respectively. They will ride along with Mission Specialists Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) and Anna Kikina of Roscosmos. The commercial crew quartet will dock to the forward port of the Harmony module 29 hours after launch to begin their station mission.

After the Dragon Endurance docks to the orbiting lab, another four station crew members will turn their attention to ending their mission and returning to Earth just over a week later. NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, with ESA (European Space Agency) astronaut Samantha Cristoforetti, who have been living on the station since April 27, will help their Crew-5 replacements adjust to life on the station. The homebound astronauts will then undock inside the SpaceX Dragon Freedom crew ship and parachute to a splashdown off the coast of Florida.

In the meantime, Lindgren and Hines began Monday focusing on how living in space is affecting their muscles. The duo used an Ultrasound device and the Myotones device to scan and measure the biochemical properties of their leg, neck, and back muscles. Watkins nourished vegetables and took photos of the plants growing for the XROOTS space agriculture study taking place in the Columbus laboratory module. NASA Flight Engineer Frank Rubio swapped glass fiber samples in the Microgravity Science Glovebox for the Intelligent Glass Optics space manufacturing investigation. Station Commander Cristoforetti serviced samples inside the Electrostatic Levitation Furnace that supports high-temperature thermophysical research in space.

The station’s two cosmonauts, two-time station visitor Sergey Prokopyev and first-time space flyer Dmitri Petelin, had their hands full on Monday keeping up with lab maintenance while continuing their station familiarization activities. Prokopyev inspected windows inside the Zvezda service module then set up Earth observation gear. Petelin worked on orbital plumbing duties before inventorying and restocking station docking hardware.
