While the International Space Station was traveling about 260 miles over the Western Australia, a SpaceX Dragon cargo spacecraft autonomously docked to the forward-facing port of the orbiting laboratory’s Harmony module at 10:30 a.m. EDT, Monday, Aug. 30. Flight Engineers Shane Kimbrough and Megan McArthur of NASA monitored operations.

Among the science experiments Dragon is delivering to the space station are:

Building bone with byproducts
REducing Arthritis Dependent Inflammation First Phase (READI FP) evaluates the effects of microgravity and space radiation on the growth of bone tissue and tests whether bioactive metabolites, which include substances such as antioxidants formed when food is broken down, might protect bones during spaceflight. The metabolites that will be tested come from plant extracts generated as waste products in wine production. Protecting the health of crew members from the effects of microgravity is crucial for the success of future long-duration space missions. This study could improve scientists’ understanding of the physical changes that cause bone loss and identify potential countermeasures. This insight also could contribute to prevention and treatment of bone loss on Earth, particularly in post-menopausal women.

Keeping an eye on eyes
Retinal Diagnostics tests whether a small, light-based device can capture images of the retinas of astronauts to document progression of vision problems known as Space-Associated Neuro-Ocular Syndrome (SANS). The device uses a commercially available lens approved for routine clinical use and is lightweight, mobile, and noninvasive. The videos and images will be downlinked to test and train models for detecting common signs of SANS in astronauts. The investigation is sponsored by ESA (European Space Agency) with the German Aerospace Center Institute of Space Medicine and European Astronaut Centre.

Robotic helpers
The Nanoracks-GITAI Robotic Arm will demonstrate the microgravity versatility and dexterity of a robot designed by GITAI Japan Inc. Results could support development of robotic labor to support crew activities and tasks, as well as inform servicing, assembly, and manufacturing tasks while in orbit. Robotic support could lower costs and improve crew safety by having robots take on tasks that could expose crew members to hazards. The technology also has applications in extreme and potentially dangerous environments on Earth, including disaster relief, deep-sea excavation, and servicing nuclear power plants. The experiment will be conducted inside the Nanoracks Bishop Airlockthe space station’s first commercial airlock.

Putting materials to the test
MISSE-15 NASA is one of a series of investigations on Alpha Space’s Materials ISS Experiment Flight Facility, which is testing how the space environment affects the performance and durability of specific materials and components. These tests provide insights that support development of better materials needed for space exploration. Testing materials in space has the potential to significantly speed up their development. Materials capable of standing up to space also have potential applications in harsh environments on Earth and for improved radiation protection, better solar cells, and more durable concrete.

Helping plants deal with stress
Plants grown under microgravity conditions typically display evidence of stress.  Advanced Plant EXperiment-08 (APEX-08) examines the role of compounds known as polyamines in the response of the small, flowering plant thale cress to microgravity stress. Because expression of the genes involved in polyamine metabolism remain the same in space as on the ground, plants do not appear to use polyamines to respond to stress in microgravity. APEX-08 attempts to engineer a way for them to do so. Results could help identify key targets for genetic engineering of plants more suited to microgravity.

Easier drug delivery
The Faraday Research Facility is a multipurpose unit that uses the space station’s EXPRESS payload rack systems, which enable quick, simple integration of multiple payloads . On this first flight, the facility hosts a Houston Methodist Research Institute experiment and two STEM collaborations, including “Making Space for Girls” with the Girl Scouts of Citrus Council in Orlando, Florida.

The Faraday Nanofluidic Implant Communication Experiment  (Faraday-NICE) tests an implantable, remote-controlled drug delivery system using sealed containers of saline solution as surrogate test subjects. The device could provide an alternative to bulky, cumbersome infusion pumps, a possible game changer for long-term management of chronic conditions on Earth. Remote-controlled drug delivery could simplify administration for people with limitations.

partnership between Faraday and Girls Scouts allows troops to play a role in conducting the control experiments, including providing them with images of the same experiments that are happening in space. The studies involve plant growth, ant colonization, and the brine shrimp lifecycle.

These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help 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 through Artemis.

Spacewalk is Postponed

The International Space Station as photographed in October of 2018.

The U.S. spacewalk outside the International Space Station originally planned for Tuesday, Aug. 24 with NASA astronaut Mark Vande Hei and JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide has been postponed due to a minor medical issue involving Vande Hei. This issue is not a medical emergency. The spacewalk is not time-sensitive and crew members are continuing to move forward with other station work and activities. Teams are assessing the next available opportunity to conduct the spacewalk following the SpaceX CRS-23 cargo resupply launch planned for Aug. 28 and upcoming Russian spacewalks. The preview briefing Aug. 23 is also being rescheduled and will be announced at a later date.

Busy Day as U.S., Russian Crews Get Ready for Spacewalks

All seven Expedition 65 crew members are gearing up three spacewalks the first of which is set to start next week. Two astronauts will go on the first spacewalk then two cosmonauts will conduct the second and third spacewalks. The other three crewmates will provide support to the spacewalkers.

The first spacewalk on Aug. 24 will see Commander Akihiko Hoshide and Flight Engineer Mark Vande Hei spend about six hours and 50 minutes setting up the Port-4 (P4) truss structure for future Roll-Out Solar Array installation work. They will install a modification kit on P4 that prepares the site for the third of six new solar arrays planned for the station.

Flight Engineers Megan McArthur and Thomas Pesquet reviewed their spacewalk support roles today including controlling the Canadarm2 robotic arm and helping the duo in and out of their U.S. spacesuits. Flight Engineer Shane Kimbrough also spent several hours Wednesday morning assembling the solar array modification kit that Hoshide and Vande Hei will install next week.

On the other side of the station in the Russian segment, cosmonauts Oleg Novitskiy and Pyotr Dubrov are preparing for two of their own spacewalks planned for early September. They are continuing to organize their spacewalk tools and equipment in the Poisk module‘s airlock. The duo will exit Poisk for both excursions and ready the Nauka Multipurpose Laboratory Module for science operations.

The Northrop Grumman Cygnus spacecraft’s hatch was opened this afternoon after successful rendezvous and berthing operations. At 6:07 a.m. EDT, NASA astronaut Megan McArthur used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as ESA (European Space Agency) astronaut Thomas Pesquet monitored Cygnus systems during its approach. Cygnus was then bolted into place on the International Space Station’s Earth-facing port of the Unity module at 9:42 a.m. EDT. Cygnus will remain at the space station for about three months until the spacecraft departs in November.

The spacecraft’s arrival brings more than 8,200 pounds of research and supplies to space station. Highlights of cargo aboard Cygnus include research studying 3D printing using simulated lunar regolith, seeking to utilize microgravity to develop new means to treat a degenerative muscle condition on Earth, investigating new tactics to control heat during operations in space and during the intense heating of reentry, and testing a technology to remove carbon dioxide from spacecraft atmospheres with applications to future NASA exploration missions.

These are just a sample of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program.

NASA has continued to assess any integrated impacts to the space station from the inadvertent firing of thrusters on the newly arrived Russian Nauka module. Routine operations have continued uninterrupted since the event, with the space station prepared for the arrival of multiple spacecraft. Consistent with NASA policies, an investigation team is being formed to review the activity. NASA’s team will begin with identifying team members and defining the scope of the investigation. The team will focus on analyzing available data, cooperating with our Russian colleagues for any information they require for their assessment, and coordinating with the other international partners.

Cygnus Installed on Unity Module for Cargo Transfers

The Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 9:42 a.m. EDT. Cygnus will remain at the space station for about three months until the spacecraft departs in November.

The spacecraft’s arrival brings more than 8,200 pounds of research and supplies to space station. Highlights of cargo aboard Cygnus include:

 From dust to dorm
Using resources available on the Moon and Mars to build structures and habitats could reduce how much material future explorers need to bring from Earth, significantly reducing launch mass and cost. The Redwire Regolith Print (RRP) study demonstrates 3D printing on the space station using a material simulating regolith, or loose rock and soil found on the surfaces of planetary bodies such as the Moon. Results could help determine the feasibility of using regolith as the raw material and 3D printing as a technique for on-demand construction of habitats and other structures on future space exploration missions.

Maintaining muscles
As people age and become more sedentary on Earth, they gradually lose muscle mass, a condition called sarcopenia. Identifying drugs to treat this condition is difficult because it develops over decades. Cardinal Muscle tests whether microgravity can be used as a research tool for understanding and preventing sarcopenia. The study seeks to determine whether an engineered tissue platform in microgravity forms the characteristic muscle tubes found in muscle tissue. Such a platform could provide a way to rapidly assess potential drugs prior to clinical trials.

Taking the heat out of space travel
Longer space missions will need to generate more power, producing more heat that must be dissipated. Transitioning from current single-phase heat transfer systems to two-phase thermal management systems reduces size and weight of the system and provides more efficient heat removal. Because greater heat energy is exchanged through vaporization and condensation, a two-phase system can remove more heat for the same amount of weight than current single-phase systems. The Flow Boiling and Condensation Experiment (FBCE) aims to develop a facility for collecting data about two-phase flow and heat transfer in microgravity. Comparisons of data from microgravity and Earth’s gravity are needed to validate numerical simulation tools for designing thermal management systems.

Cooler re-entries
The Kentucky Re-Entry Probe Experiment (KREPE) demonstrates an affordable thermal protection system (TPS) to protect spacecraft and their contents during re-entry into Earth’s atmosphere. Making these systems efficient remains one of space exploration’s biggest challenges, but the unique environment of atmospheric entry makes it difficult to accurately replicate conditions in ground simulations. TPS designers rely on numerical models that often lack flight validation. This investigation serves as an inexpensive way to compare these models to actual flight data and validate possible designs. Before flying the technology on the space station, researchers conducted a high-altitude balloon test to validate performance of the electronics and communications.

Getting the CO2 out
Four Bed CO2 Scrubber demonstrates a technology to remove carbon dioxide from a spacecraft. Based on the current system and lessons learned from its nearly 20 years of operation, the Four Bed CO2 Scrubber includes mechanical upgrades and an improved, longer-lasting absorbent material that reduces erosion and dust formation. Absorption beds remove water vapor and carbon dioxide from the atmosphere, returning water vapor to the cabin and venting carbon dioxide overboard or diverting it to a system that uses it to produce water. This technology could improve the reliability and performance of carbon dioxide removal systems in future spacecraft, helping to maintain the health of crews and ensure mission success. It has potential applications on Earth in closed environments that require carbon dioxide removal to protect workers and equipment.

Mold in microgravity
An ESA investigation, Blob, allows students aged 10 to 18 to study a naturally-occurring slime mold, Physarum polycephalum, that is capable of basic forms of learning and adaptation. Although it is just one cell and lacks a brain, Blob can move, feed, organize itself, and even transmit knowledge to other slime molds. Students replicate experiments conducted by ESA astronaut Thomas Pesquet to see how the Blob’s behavior is affected by microgravity. Using time-lapse video from space, students can compare the speed, shape, and growth of the slime molds in space and on the ground. The National Center for Space Studies (CNES) and the National Center for Scientific Research (CNRS) in France coordinate Blob.

These are just a sample of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program.

Cygnus also will deliver a new mounting bracket that astronauts will attach to the port side of the station’s backbone truss during a spacewalk planned for late August. The mounting bracket will enable the installation of one of the next pair of new solar arrays at a later date.
