The Expedition 63 crew kicked off the work week exploring space agriculture and spacecraft technologies. The trio also split the day on upcoming mission preparations and International Space Station maintenance.

Ongoing botany studies on the station have been teaching scientists, engineers and astronauts how to grow crops in space, so crews can feed themselves farther away from Earth. Future astronauts on long-term missions to the Moon, Mars and beyond will need to be self-sufficient with less support from mission controllers and resupply missions.

Commander Chris Cassidy set up the Advanced Plant Habitat during the afternoon for upcoming grow operations in the research facility. The controlled plant growth chamber automates the delivery of nutrients and light to support a variety edible plants for harvesting, analysis and tasting.

Cassidy is also gearing up for a U.S. resupply mission due to replenish the orbiting lab in early October. The NASA astronaut is sharpening his robotics skills on a computer to get ready to capture Northrop Grumman’s Cygnus cargo craft with the Canadarm2 robotic arm.

A Russian technology experiment is using acoustics to locate micrometeoroid impacts on the space station. The two flight engineers, Anatoly Ivanishin and Ivan Vagner, partnered during the morning checking hardware and downloading data that may pinpoint the location of high-speed particle hits on the outside of the space lab.

The cosmonaut duo then spent the rest of Monday servicing life support gear and updating computer systems.

Mission controllers at NASA’s Johnson Space Center are returning to normal operations today after setting backup control centers at remote locations. The International Space Station support team returned to Houston after setting up remote operations earlier this week when Hurricane Laura neared the Texas-Louisiana border.

The three Expedition 63 crew members continued their standard science and maintenance tasks this week after orbiting above Laura and sending down video and imagery of the storm. This comes after a four-night stay in the station’s Russian segment during a test to locate the source of a minor cabin air pressure leak.

Today, Commander Chris Cassidy worked on swapping components on a U.S. oxygen generator. He replaced a hydrogen sensor then cleaned the critical life support device. Afterward, the NASA astronaut checked samples in the Materials Science Laboratory which processes experiments to discover new uses for a variety of materials such as metals, alloys, polymers, and more.

Veteran cosmonaut Anatoly Ivanishin worked Friday morning servicing communications gear inside the Soyuz MS-16 crew ship. During the afternoon, the three-time station resident handed Russian radiation detection gear to Cassidy for deployment in the orbiting lab’s U.S. segment.

First-time space flyer Ivan Vagner of Roscosmos spent his day focusing on a variety of space technology studies using advanced photography gear. He explored ways to improve orbital navigation and improve the detection of landmarks on Earth.

Station Crew Re-Enters U.S On-Orbit Segments, Mission Control Preps for Storm

The International Space Station

The Expedition 63 crew ended its stay isolated in the Russian segment of the International Space Station this morning after an extended leak test. Mission Control also deployed remote teams to maintain 24/7 support for the station and its crew as Hurricane Laura approaches the Texas Gulf Coast.

Commander Chris Cassidy started the day reopening the hatches to the U.S. segment to begin resuming normal station operations. He reactivated U.S. life support equipment and restowed U.S. gear used during the crew’s weekend stay in the Zvezda service module.

Mission control will study the test data this week in an effort to determine the source of a cabin air leak detected in September of 2019. The rate is still well within segment specifications and presents no danger to the crew or the space station. The station’s atmosphere is maintained at a pressure comfortable for the crew members, and a tiny bit of that air leaks over time, requiring routine repressurization from nitrogen tanks delivered on cargo resupply missions.

Roscosmos Flight Engineer Anatoly Ivanishin spent the morning reconfiguring the Russian segment of the orbiting lab. The veteran station cosmonaut checked pressure valves and communications gear while opening hatches to various Russian modules.

Flight Engineer Ivan Vagner, on his first station mission, started the day resetting Russian life support equipment and sampling the air in Zvezda for analysis. Vagner also had time for science during the afternoon studying the Earth’s nighttime atmosphere and exploring ways to improve locating landmarks on Earth for photography.

Meanwhile, personnel at NASA’s Johnson Space Center in Houston are monitoring Hurricane Laura and making general preparations at the center. A small team of flight controllers germane to monitoring and sending commands for the most important station systems were sent to a backup control center hub in central Texas in advance of the storm.

A full team of station flight controllers is getting set up at the Marshall Space Flight Center in Huntsville, Alabama, to take over longer-term control of station systems should that become necessary. This backup activity is planned for each hurricane season or for some other extenuating circumstance and will be executed with no impact on critical station operations or the safety of the crew.

Crew Spending Another Day in Russian Segment

The three Expedition 63 crew members will spend another day inside the Russian segment of the International Space Station. Mission controllers are continuing their leak detection work today to collect more data.

All of the orbiting lab’s hatches will remain closed until Tuesday morning to give ground specialists additional time to collect data and monitor pressure readings in each module. The rate is still well within segment specifications and presents no danger to the crew or the space station.

The station’s atmosphere is maintained at pressure comfortable for the crew members, and a tiny bit of that air leaks over time, requiring routine repressurization from nitrogen tanks delivered on cargo resupply missions. In September 2019, NASA and its international partners first saw indications of a slight increase above the standard cabin air leak rate. Because of routine station operations like spacewalks and spacecraft arrivals and departures, it took time to gather enough data to characterize those measurements. That rate has slightly increased, so the teams are working a plan to isolate, identify and potentially repair the source.

Meanwhile, the station trio is staying comfortable in the Zvezda service module with access to the Poisk mini-research module,  the Progress 76 cargo craft and their Soyuz MS-16 crew ship. Commander Chris Cassidy of NASA and Roscosmos Flight Engineers Anatoly Ivanishin and Ivan Vagner mainly focused on Earth photography Monday. The station’s Russian segment has a variety of windows the crew can look out with advanced camera gear for their Earth observation activities.

Crew Spending Weekend in Station’s Russian Segment

The three Expedition 63 crew members living aboard the International Space Station will spend the weekend inside the orbiting lab’s Russian segment. Commander Chris Cassidy and his crewmates Ivan Vagner and Anatoly Ivanishin will stay in the Zvezda service module from Friday night into Monday morning.

The station’s atmosphere is maintained at pressure comfortable for the crew members, and a tiny bit of that air leaks over time, requiring routine repressurization from nitrogen tanks delivered on cargo resupply missions. In September 2019, NASA and its international partners first saw indications of a slight increase above the standard cabin air leak rate. Because of routine station operations like spacewalks and spacecraft arrivals and departures, it took time to gather enough data to characterize those measurements. That rate has slightly increased, so the teams are working a plan to isolate, identify, and potentially repair the source. The leak is still within segment specifications and presents no immediate danger to the crew or the space station.

All the space station hatches will be closed this weekend so mission controllers can carefully monitor the air pressure in each module. The test presents no safety concern for the crew. The test should determine which module is experiencing a higher-than-normal leak rate. The U.S. and Russian specialists expect preliminary results should be available for review by the end of next week.

The three station residents will have plenty of room in Zvezda this weekend. The module provides the living quarters that enabled permanent human habitation to begin nearly 20 years ago when the Expedition 1 crew arrived at the station Nov. 2, 2000. Cassidy, Vagner, and Ivanishin also will have access to the Poisk mini-research module and their Soyuz MS-16 crew ship for the duration of their stay.

 

Space Traffic Clear at Station Until October

The Expedition 63 crew has turned its attention toward space science and lab maintenance after releasing a Japanese cargo craft from the International Space Station on Tuesday. More cargo and crew missions to replenish the orbiting lab are planned for October.

Commander Chris Cassidy switched off communications gear today used to send commands to Japan’s H-II Transfer Vehicle-9 (HTV-9) after its departure on Tuesday. The HTV-9 will orbit Earth until Thursday morning when it descends into the atmosphere for a fiery, but safe demise over the South Pacific.

The NASA commander spent the rest of the day working on orbital plumbing and life support gear. Cassidy removed and replaced the Waste and Hygiene Compartment’s recycle tank located in the Tranquility module. He also inspected out gear that analyzes organic compounds in the station’s air.

Veteran station cosmonaut Anatoly Ivanishin focused on battery work as he installed current converters throughout the lab’s Russian segment. First-time cosmonaut Ivan Vagner spent Wednesday morning working on more orbital plumbing before exploring ways to improve Earth photography techniques and determine how mission events impact the orbiting lab.

Space traffic will be clear at the space station for the rest of August and into September. The mission pace will pick back up in October with a U.S. Cygnus cargo ship from Northrop Grumman, the Expedition 64 crew and the SpaceX Crew-1 mission all to set to arrive within a period of three weeks.

Japanese Cargo Craft Completes Station Mission

Japan’s HTV-9 resupply ship is on its own after being released from the Canadarm2 robotic arm completing a three-month cargo mission at the station.

Eleven years after the launch of the first H-II Transfer cargo vehicle (HTV) to the International Space Station, the Japan Aerospace Exploration Agency’s (JAXA’s) HTV-9 departed the orbital laboratory today at 1:36 p.m. EDT.

Earlier today, flight controllers operating from NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston used the space station’s Canadarm2 robotic arm to detach the cargo spacecraft from the station’s Harmony module, then moved the spacecraft into its release position. Expedition 63 Commander Chris Cassidy of NASA used the Canadarm2 robotic arm to release the spacecraft from the station ending its three-month stay.

This was the final station departure of JAXA’s first-generation Kounotori, or “white stork,” cargo craft, nine of which have delivered more than 40 tons of supplies to space station crews.  JAXA is developing a new fleet of HTV cargo craft, the HTV-X, which is targeted for its first launch in 2022.

The spacecraft launched from the Tanegashima Space Center in Japan on May 20, arriving May 25 to deliver about four tons of supplies and experiments to the orbital complex, including new lithium-ion batteries that were used to upgrade the station’s power systems. The new-technology batteries were installed through a series of spacewalks along the far port truss “backbone” of the station.

HTV-9 will be commanded by JAXA flight controllers at its HTV control center in Tsukuba, Japan, to move away from the station and, on Aug. 20, to fire its deorbit engine in a burn that will send it back into Earth’s atmosphere. Loaded with trash from the space station, the spacecraft will burn up harmlessly over the Pacific Ocean.

For nearly 20 years, astronauts have continuously lived and work on the space station, testing technologies, performing science and developing the skills needed to explore farther from Earth. As a global endeavor, 240 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 3,000 research and educational investigations from researchers in 108 countries and areas.

Roscosmos Flight Engineer Ivan Vagner will back up Cassidy and monitor the release of the HTV-9 as it completes its 85-day cargo mission. NASA TV will cover the activities live starting at 1:15 p.m.

The HTV-9 will spend two more days orbiting Earth before a fiery, atmospheric demise over the South Pacific. JAXA (Japan Aerospace Exploration Agency) is developing an upgraded fleet of HTV-X space station suppliers, replacing the HTV series of spaceships, targeted for their first launch in 2022.

The Expedition 63 and 64 crews are due to trade places at the orbiting lab beginning in mid-October. The Soyuz MS-17 crew ship is slated to blast off from the Baikonur Cosmodrome in Kazakhstan on Oct. 14 and dock to the station’s Rassvet module. NASA astronaut Kate Rubins with Roscosmos cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will then begin a six-month space research mission.

One week later on Oct. 21, Cassidy will wrap up his mission with crewmates Vagner and Russian Flight Engineer Anatoly Ivanishin. The trio will enter the Soyuz MS-16 crew ship, undock from the Poisk module and parachute to a landing in Kazakhstan ending a 195-day expedition in space.

NASA and SpaceX have announced the launch of the SpaceX Crew-1 mission to the station for no earlier than Oct. 23. Mike Hopkins of NASA will command the first operational flight of the Crew Dragon spacecraft piloted by first-time NASA astronaut Victor Glover. They will be joined by Mission Specialists Shannon Walker of NASA and Soichi Noguchi of JAXA, both previous station residents.

Canada’s versatile robotic arm, the 57.7-foot-long Canadarm2, is in place and ready to grapple and release Japan’s resupply ship from the International Space Station next week. The Expedition 63 crew is continuing to pack the cargo craft while training for its robotic release.

Commander Chris Cassidy of NASA will command the Canadarm2 to release the H-II Transfer Vehicle-9 (HTV-9) on Tuesday at 1:35 p.m. EDT. Roscosmos cosmonaut and Flight Engineer Ivan Vagner will support Cassidy at the robotics workstation in the station’s “window to the world,” the cupola.

Both crewmates will be practicing the robotic maneuvers on a computer Friday and Monday to prepare for the HTV-9’s release. Cassidy finalized packing the HTV-9 with discarded gear and will close the hatch to the Japanese resupply ship on Monday. NASA TV will begin its live coverage of the release activities on Tuesday at 1:15 p.m.

Space traffic will pick up again in October with a U.S. cargo ship slated to arrive and a crew exchange planned at the orbiting lab. Northrop Grumman is targeting early October for the rendezvous and robotic capture of its Cygnus cargo craft at the station.

On Oct. 14, three Expedition 64 crew members will launch aboard the Soyuz MS-17 crew ship toward the orbital lab. NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will take a six-hour ride that day and dock to the Rassvet module beginning a six-month station mission.

One week later, Cassidy will end his mission along with Expedition 63 crewmates Vagner and Russian Flight Engineer Anatoly Ivanishin. The trio will undock from the Poisk module in the Soyuz MS-16 crew ship on Oct. 21 and parachute to a landing in Kazakhstan ending a 195-day research mission aboard the station.

The Expedition 63 crew trio continued ongoing space research and orbital housekeeping aboard the International Space Station today. Mission controllers are also preparing the Canadarm2 robotics arm for departure operations with Japan’s ninth resupply ship.

Commander Chris Cassidy split his Thursday shift with physics research in the morning and plumbing and electronics maintenance in the afternoon. The veteran NASA astronaut first checked samples inside the Electrostatic Levitation Furnace that levitates, melts and solidifies materials exposed to extreme temperatures. After lunch, he connected water recovery system cables then checked emergency communications gear.

Astrobee, a set of cube-shaped robotic free-flyers, was turned on today inside the Japanese Kibo laboratory module. The devices were autonomously maneuvering throughout Kibo and live-streaming video during the afternoon so engineers could monitor the operations.

Cosmonauts Anatoly Ivanishin and Ivan Vagner tackled their portion of research and maintenance today  in the Russian segment of the orbiting lab. Ivanishin once again continued his space biology and Earth studies. Vagner worked on another Earth observation experiment and also organized the Pirs docking compartment.

Attached to the Earth-facing port of the Harmony module since May 25, Japan’s H-II Transfer Vehicle-9 (HTV-9) is nearing the end of its mission. Robotics controllers will maneuver the Canadarm2 in position on Friday before grappling and removing the HTV-9 from Harmony on Tuesday.

Cassidy will take over afterward and command the 57.7-foot-long robotic arm to release the HTV-9 into Earth orbit the same day. Nicknamed Kounotori, or “white stork” for its delivery mission, the Japanese resupply ship will end its mission two days later for a fiery, but safe demise over the South Pacific.
