Crew Relaxes as Two Robotic Arms Prepare for Payload Handoffs

The Expedition 59 crew has a light duty day today with some science work on the schedule. Meanwhile, robotics controllers are preparing to swap external payloads in the unpressurized trunk of the SpaceX Dragon cargo craft.

NASA Flight Engineer Christina Koch checked samples today as she continued exploring why pathogens become more virulent in space. Later, she set up hardware for the Kidney Cells experiment that seeks innovative treatments for humans on Earth and in space.

Astronaut Nick Hague of NASA retrieved sample trays from a materials exposure experiment brought back inside the Kibo lab module. Fellow NASA astronaut Anne McClain checked on mice being observed for changes to their immune systems in microgravity.

Two new experiments are ready for robotic extraction from the SpaceX Dragon and installation on the International Space Station starting Thursday night and into the weekend. An older experiment will be removed from the station and placed back in Dragon.

The remotely controlled Canadarm2 robotic arm will first extract the Orbiting Carbon Observatory-3 (OCO-3) from Dragon’s trunk. Japan’s robotic arm will then take hold of the OCO-3 and install the global carbon detection device on Kibo’s external pallet. The Canadarm2 will then extract and install the Space Test Program-Houston 6 hardware for space physics research on the station’s truss structure.

Finally, the Japanese robotic arm will hand off the Cloud-Aerosol Transport System (CATS) to the Canadarm2 for installation in Dragon’s trunk. CATS will burn up over Earth’s atmosphere when Dragon’s trunk separates during its reentry at the end of May. A SpaceX Dragon resupply ship delivered CATS in January of 2015 for robotic installation outside Kibo. CATS successfully demonstrated low cost atmospheric monitoring techniques from the station.

Science Aboard Station Today Impacts Astronaut Health Long-Term

The International Space Station has all but one of its seven ports occupied by two crew ships and four cargo ships today. With plenty of food, fuel and supplies, the Expedition 59 crew is busy conducting new science experiments delivered to the orbital lab.

The crew researched an array of space biology today including pathogen virulence, immune system changes and upper body pressure that can affect mission success. Human research and life science is key in microgravity as NASA learns to support healthy astronauts for longer missions farther into space.

NASA Flight Engineer Christina Koch continued studying why pathogens increase in virulence due to the weightless environment of space. She performed inoculation procedures on cell cultures to help scientists understand critical cellular and molecular changes that occur on the absence of gravity.

Koch then joined fellow astronauts Anne McClain and David Saint-Jacques in the afternoon exploring how the immune system responds during a long-term space mission. The crew is observing dozens of mice on the orbital lab to characterize the response changes since the mouse immune system closely parallels that of humans.

McClain also participated on more Fluid Shifts research with Flight Engineers Alexey Ovchinin and Flight Engineer Nick Hague. The trio worked with a variety of biomedical hardware today observing the impacts of increased head and eye pressure caused by microgravity. The long-running human research experiment seeks to reverse the upward flow of fluids and alleviate the symptoms reported by astronauts.

New Science Being Unpacked and Worked Aboard Orbital Lab

Six spaceships are now parked at the International Space Station and the Expedition 59 crew is working on the newest science delivered Monday. Astronauts will continue to live and work in space longer and scientists want to know how humans and a variety of other organisms adapt to support these missions.

NASA astronaut Anne McClain tended to several dozen mice delivered to the orbital lab Monday on the SpaceX Dragon cargo craft. The rodents’ immune systems are similar to humans and scientists are monitoring them to detect any changes caused microgravity.

NASA astronaut Christina Koch set up the Microgravity Science Glovebox today to begin operations with the new Micro-14 pathogen study. Microgravity can increase the virulence of pathogens and doctors are seeking to understand the process to keep space crews safe and healthy.

Koch and McClain both started Tuesday unpacking frozen biological samples from Dragon. The duo stowed the samples into different science freezers aboard the station for later analysis and experimental work.

McClain, Commander Oleg Kononenko and Flight Engineer Nick Hague also explored head and eye pressure caused by upward fluid shifts due to the effects of microgravity. The long-running human research experiment seeks to reverse the upward flow and alleviate the symptoms reported by astronauts.

Busy Monday as Astronauts Grapple Dragon and Store Critical Experiments

This morning, just two days following its nighttime launch from the Florida coast, SpaceX’s Dragon cargo spacecraft was captured and installed on the Earth-facing side of the International Space Station’s Harmony module at 9:32 a.m. EDT.

Expedition 59 astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA successfully employed the space station’s robotic arm to grapple Dragon at 7:01 a.m., which brings the number of spaceships docked at the space station to six. Other vehicles visiting include Russia’s Progress 71 and 72 resupply ships and the Soyuz MS-11 and MS-12 crew ships, as well as Northrop Grumman’s Cygnus space freighter.

Dragon’s arrival heralds a busy week for the crew. Today, NASA astronauts Anne McClain and Christina Koch unpacked and activated time-critical experiments after completing checkout of the spacecraft. Fresh biological samples, such as kidney cells, were stowed in science freezers and incubators for later analysis. New lab mice were also quickly transferred and housed in specialized habitats to enhance research for an immune system study that aims to keep astronauts healthy for long-duration missions in space, which will become even more commonplace as our destinations extend to the Moon and beyond.

SpaceX’s 17th cargo flight to the space station under NASA’s Commercial Resupply Services contract supports dozens of new and existing investigations. NASA’s research and development work aboard the space station contributes to the agency’s deep space exploration plans, including returning astronauts to the Moon’s surface in five years.

This latest commercial cargo delivery refreshed the orbiting laboratory with 5,500 pounds of research, crew supplies and hardware.

SpaceX Cargo Craft Attached to Station

Two days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module at 9:32 a.m. EDT.

The 17th contracted commercial resupply mission from SpaceX (CRS-17) delivers more than 5,500 pounds of research, crew supplies and hardware to the orbiting laboratory.

Here’s some of the science arriving at station:

Scientists are using a new technology called tissue chips, which could help predict the effectiveness of potential medicines in humans. Fluid that mimics blood can be passed through the chip to simulate blood flow, and can include drugs or toxins. In microgravity, changes occur in human health and human cells that resemble accelerated aging and disease processes. This investigation allows scientists to make observations over the course of a few weeks in microgravity rather than the months it would take in a laboratory on Earth.

The Hermes facility allows scientists to study the dusty, fragmented debris covering asteroids and moons, called regolith. Once installed by astronauts on the space station, scientists will be able to take over the experiment from Earth to study how regolith particles behave in response to long-duration exposure to microgravity, including changes to pressure, temperate and shocks from impacts and other forces. The investigations will provide insight into the formation and behavior of asteroids, comets, impact dynamics and planetary evolution.

These are just a few of the hundreds of investigations that will help us learn how to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars. Space station research also provides opportunities for other U.S. government agencies, private industry, and academic and research institutions to conduct microgravity research that leads to new technologies, medical treatments, and products that improve life on Earth.

After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with about XX pounds of cargo and research.
