MEDIA ADVISORY M21-097
NASA Spacewalk Briefing to Highlight New Solar Array Installation

Two astronauts will venture outside the International Space Station Tuesday, Aug. 24, for a spacewalk to install a support bracket in preparation for future installation of the orbiting laboratory’s third new solar array.

NASA will discuss the upcoming spacewalk during a news conference at 2 p.m. EDT Monday, Aug. 23. Live coverage of the news conference and spacewalk will air on NASA Television, the agency’s website, and the NASA app.

NASA astronaut Mark Vande Hei and astronaut Akihiko Hoshide of the Japan Aerospace Exploration Agency will install a support bracket, called a modification kit, on the inward port side of the station’s backbone truss structure in a position known as P4, which is closest to the station’s pressurized living space. The kit prepares the site for future installation and deployment of the third of six new International Space Station Roll-Out Solar Arrays (iROSA) to upgrade one of the station’s eight power channels known as 4A, which provides partial power to the U.S. Laboratory, the Harmony module, and the Columbus module. The modification kit will be attached to the mast canister at the base of the original solar arrays.

The crew will also replace a device that measures the electrical charging potential of the arrays and associated surfaces in its vicinity, called a floating point measurement unit, on a separate truss.

Reporters who wish to participate in the news conference at NASA’s Johnson Space Center in Houston by telephone must call the Johnson newsroom at 281-483-5111 to RSVP no later than 4 p.m. Friday, Aug. 20. Reporters will not be invited to attend briefings on site at NASA centers due to safety restrictions related to the ongoing COVID-19 pandemic. Anyone following the briefing on social media may ask questions using #AskNASA.

News conference participants are:

    Jeff Arend, NASA International Space Station Program systems engineering integration office manager.
    Adi Boulos, NASA spacewalk flight director.
    Sandy Moore, NASA spacewalk officer.

Live coverage of the spacewalk will begin at 7 a.m. EDT on Tuesday, Aug. 24, with the crew members scheduled to exit the station’s Quest airlock around 8:30 a.m. The spacewalk will last approximately 6 hours and 50 minutes.

Hoshide will serve as extravehicular crew member one (EV1), with red stripes on his spacesuit, while Vande Hei will be extravehicular crew member two (EV2), with an unmarked suit. This will be the fourth spacewalk for Hoshide, the fifth spacewalk for Vande Hei, and the station’s 242nd in support of assembly, maintenance, and upgrades.

The spacewalk follows three other recent ones to install the first pair of new iROSA arrays. On June 16, Kimbrough and Pesquet moved the first to a mounting bracket on the 2B power channel on the port 6 truss, where it was secured in its folded configuration. On June 20, the duo returned to the 2B power channel to complete installation and deployment. The astronauts completed installation and deployment of the second of the six new arrays in a spacewalk June 25.

The station’s original solar arrays are functioning well, but have begun to show signs of degradation, which was expected, as they were designed for a 15-year service life. The first pair of original solar arrays were deployed in December 2000 and have been powering the station for more than 20 years, exceeding expectations. They are now augmented with the first pair of iROSAs positioned in front of them. When all six of the new arrays are in place, the station’s total available power will increase from 160 kilowatts to a maximum of 215. The same roll-out solar array design will be used to power elements of Gateway, a new lunar-orbiting outpost in development by NASA’s commercial and international partners.

In November 2020, the International Space Station surpassed its 20-year milestone of continuous human presence, providing opportunities for unique research and technological demonstrations that help prepare for long-duration missions to the Moon and Mars and also improve life on Earth. Over that time, 244 people from 19 countries have visited the orbiting laboratory that has hosted nearly 3,000 research investigations from researchers in 108 countries and areas.

    The kind of photo that could warrant a caption competition, but reality is probably more incredible than you imagine! This experiment is about plants. Can plants sense gravity? This is the kind of question that could make you say yes of course, or no of course not, but then when you think about it... Researchers think about these things and we have shown in space (in previous research on the Space Station) that plants do indeed feel gravity (or react to it at least). But then comes the immediate follow-on question... how, and maybe even, why? That's what the BRIC-24 experiment is about, or Biological Research In Canisters-24. In particular this experiment was looking at microscopic water-filled membranes in T. Arabidopsis plant (the organelle contacts and vacuole fusion). This type of plant, which is a cress, is our go-to research plant in space, it is probably the plant scientists know most about in the world and beyond! And the pistol grip? It allows us to activate the experiment, once we pull the trigger, the experiment starts inside the container!

Spacewalk is Postponed

Mark Garcia Posted on August 23, 2021

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. For updates, please visit https://blogs.nasa.gov/spacestation.

Thanks for everyone’s concern. I have a pinched nerve in my neck that caused us to reschedule today’s spacewalk. The support from family, friends, and NASA leadership has been fantastic. I’m looking forward to installing this IROSA Mod kit. Today just wasn't the right day.

Crew Gets Ready for Cargo Dragon and Russian Spacewalks

Mark Garcia Posted on August 24, 2021

The Expedition 65 crew is turning its attention to this weekend’s arrival of a U.S. cargo craft and a pair of Russian spacewalks starting several days later.

SpaceX is planning to launch its Cargo Dragon spacecraft to the International Space Station on Saturday at 3:37 a.m. EDT. It will arrive on Sunday and dock autonomously at 11 a.m. to the Harmony module’s forward international docking adapter packed with new science experiments and crew supplies. NASA TV will broadcast both launch and docking and NASA Flight Engineers Shane Kimbrough and Megan McArthur will be on duty monitoring the Cargo Dragon’s arrival.

Cargo transfers are still ongoing inside the U.S. Cygnus space freighter from Northrop Grumman attached to the Unity module. Commander Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) partnered with Flight Engineer Thomas Pesquet of ESA (European Space Agency) offloading some of the four tons cargo packed inside Cygnus during the afternoon.

Two spacewalks are planned to set up Russia’s newest module, the Nauka Multipurpose Laboratory Module, for science operations on Sept. 3 and 9. Cosmonauts Oleg Novitskiy and Pyotr Dubrov have been preparing their Orlan spacesuits and Russian spacewalk hardware inside the Poisk module where they will begin both spacewalks.

NASA Flight Engineer Mark Vande Hei joined Hoshide in the U.S. Quest airlock today stowing their U.S. spacesuits and spacewalk tools. Today’s spacewalk to prepare the International Space Station for its third Roll-Out Solar Array was postponed by station managers early Monday.

During today's (8/27) briefing on CRS-23, Joel Montelbano said that this EVA has been rescheduled for Aug. 12.  Can someone confirm that he meant Sept. 12?

In addition, Thomas Pesquet will replace Mark T. Vande Hei.

Indeed, it appears so!

Additionally, Pesquet is likely going to surpass Parmitano (https://forum.nasaspaceflight.com/index.php?topic=54044.msg2254504#msg2254504) for most cumulative EVA time for a non US / Russian astronaut.
Hoshide might also surpass Noguchi for the most cumulative EVA time to become the most experienced JAXA EVA astronaut.

For those unaware (like me), Hoshide is prepping the FPMU (https://forum.nasaspaceflight.com/index.php?action=dlattach;topic=54588.0;attach=2057393;sess=61833) which will replace the failing unit.
I assume that the replacement unit came up on NG-16 as the crew were already assembling it on the 16th (https://blogs.nasa.gov/stationreport/2021/08/16/) (before CRS-23's launch)

Cosmonauts, Astronauts Gearing Up for Two Spacewalks

Mark Garcia Posted on September 7, 2021

Two Expedition 65 cosmonauts will soon exit the International Space Station for the second spacewalk in less than week to continue configuring a Russian science module. Meanwhile, two astronauts are gearing up for another spacewalk, while the rest of the crew conducts space research and lab maintenance.

Russia’s new Nauka multipurpose laboratory module (MLM) saw its first power and ethernet cable connections last Friday during a seven-hour and 54-minute spacewalk with Flight Engineers Oleg Novitskiy and Pyotr Dubrov. The duo from Roscosmos will perform another spacewalk on Thursday at 11 a.m. EDT to continue more Nauka cable connections and install new handrails on the MLM.

The two cosmonauts spent Tuesday getting their Orlan spacesuits ready, organizing spacewalk tools and preparing the Poisk airlock for Thursday’s excursion. NASA TV will begin its live spacewalk coverage at 10:30 a.m. on the NASA app and the agency’s website.

Just three days after that two astronauts will exit the U.S. Quest airlock to modify the Port-4 (P4) truss structure and ready the orbital lab for its third set of Roll-Out Solar Arrays. Commander Akihiko Hoshide from the Japan Aerospace Exploration Agency (JAXA) and Flight Engineer Thomas Pesquet from ESA (European Space Agency) will don their U.S. spacesuits on Sunday and begin their spacewalk at 8:30 a.m.

The spacewalking pair today reviewed their tools and the modification kit they will install on P4 then studied the upcoming robotics maneuvers planned for the excursion on a computer. NASA TV will broadcast Sunday’s spacewalk starting at 7 a.m.

The station’s three NASA astronauts focused mainly on a variety of research work as well as the upkeep of the orbital lab.

Flight Engineer Megan McArthur started Tuesday exploring how microgravity affects drug metabolism. She first retrieved genetic samples from a science freezer then analyzed them to help scientists understand biological changes in space and monitor astronaut health.

McArthur then partnered with NASA astronaut Mark Vande Hei in the afternoon reviewing their support roles for Sunday’s spacewalk with Hoshide and Pesquet. Vane Hei then joined Flight Engineer Shane Kimbrough and serviced life support components that remove carbon dioxide from the station’s cabin.

Crew Readies for Thursday, Sunday Spacewalks as Science Rolls On

Mark Garcia Posted on September 8, 2021

Two Expedition 65 cosmonauts are ready for their second spacewalk to continue outfitting Russia’s new science module on Thursday. Meanwhile, another spacewalk is due to take place on Sunday to modify the International Space Station’s power system.

Cosmonauts Oleg Novitskiy and Pyotr Dubrov wrapped up their spacewalk reviews and Orlan spacesuit checks just before lunchtime on Wednesday. The Russian duo is ready to begin Thursday’s spacewalk set to begin at 11 a.m. EDT when they open the hatch on the Poisk airlock to the vacuum of space. NASA TV will begin its live spacewalk coverage at 10:30 a.m. on the NASA app and the agency’s website.

They will spend about six-and-a-half hours continuing power and ethernet cable connections and installing handrails on the Nauka multipurpose laboratory module. The three-time spacewalkers will also complete tasks deferred from the Sept. 3 spacewalk including more ethernet cable connections, cable jettisoning and biology experiment installations.

Another spacewalk is scheduled to start Sunday at 8:30 a.m. to install a modification kit on the station’s Port-4 (P4) truss structure. Astronauts Akihiko Hoshide and Thomas Pesquet are preparing for that spacewalk to ready the P4 for the orbiting lab’s third Roll-Out Solar Array due to arrive on a SpaceX Cargo Dragon mission early next year. NASA TV will begin its live coverage at 7 a.m. as the experienced astronauts prepare to exit the U.S. Quest airlock in their U.S. spacesuits for a six-and-a-half hour spacewalk.

Meanwhile, science and maintenance continued on the orbiting lab with the crew finding time to work on human research, biology, and combustion. Pesquet from ESA (European Space Agency) studied how astronauts grip objects and move their limbs in microgravity while NASA astronaut Shane Kimbrough fed rodents and cleaned their habitats during the morning.

Hoshide and NASA Flight Engineer Mark Vande Hei worked on a pair of different combustion studies today. Hoshide, the commander from the Japan Aerospace Exploration Agency (JAXA), removed combustion research hardware from the Kibo laboratory module‘s multipurpose small payload rack. Vande Hei replaced an igniter inside the Combustion Integrated Rack for the ACME series of space combustion studies.

NASA Flight Engineer Megan McArthur focused on orbital plumbing tasks and dismantling air resupply tanks during the morning. After lunch, she turned her attention to unpacking the Cargo Dragon vehicle then joining Vande Hei for a procedures review conference with Sunday’s spacewalkers Hoshide and Pesquet.

Fourth spacewalk for Alpha mission
09/09/2021

ESA astronaut Thomas Pesquet and Japanese astronaut Akihiko Hoshide are set to leave the International Space Station on a spacewalk on Sunday 12 September.

The spacewalk is part of the upgrades for the Space Station’s solar panels, installing a new generation of roll-out panels in front of the current set that are reaching the end of their useful life.

The spacewalk begins at 14:30 CEST (12:30 GMT) when the duo are set to leave the Quest airlock. This sortie will see Thomas and Aki prepare the P4 truss for the new solar arrays that will arrive on a cargo supply mission in 2022.

Thomas is an experienced spacewalker conducting three spacewalks on this mission to install the first two new roll-up arrays, and two spacewalks during his first mission Proxima in 2017. Akihiko has also conducted three spacewalks in 2012 from the International Space Station. He is currently the Space Station commander, a role that he will pass on to Thomas later this year.

Watch the spacewalk on ESA television that will air the NASA coverage from 15:00 CEST (13:00 GMT). The spacewalk is set to last around six hours. Follow the spacewalk on Twitter with @esaspaceflight.

NASA TV Coverage Begins for Power System Mods Spacewalk

Mark Garcia Posted on September 12, 2021

NASA Television coverage of today’s spacewalk with astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of ESA (European Space Agency) is now underway and is also available on the NASA app and the agency’s website.

The crew members of Expedition 65 are preparing to go outside the International Space Station for a spacewalk scheduled to begin at approximately 8:30 a.m. EDT and last about six and a half hours. They are ahead of schedule.

The crew is in their spacesuits in the airlock in preparation to exit the space station and begin today’s activities that will focus on attaching a support bracket in preparation for future installation of the orbiting laboratory’s third new solar array. NASA astronauts Megan McArthur and Mark Vande Hei are assisting Hoshide and Pesquet in preparations before they exit the station.

Hoshide and Pesquet will work on the port side of the station’s backbone truss structure closest to the station’s pressurized living space, a position known as P4. They will work together to build a bracket structure and attach the bracket and support struts to the mast canister, the base, of one of the P4 solar arrays. The modification kit will prepare the site for future installation and deployment of the third of six new International Space Station Roll-Out Solar Arrays (iROSAs).

The crew also will replace a device that measures the electrical charging potential of the arrays and associated surfaces in its vicinity, called a floating point measurement unit, on a separate truss section.

Leading the mission control team today is Flight Director Adi Boulos with support from Sandy Moore as the lead spacewalk officer and NASA astronaut Jessica Watkins acting as the capsule communicator, or CAPCOM, to the crew.

International Astronauts Begin Spacewalk to Modify Power System

Mark Garcia Posted on September 12, 2021

Astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of ESA (European Space Agency) have begun the first International Space Station spacewalk conducted by two international partner astronauts out of the station’s Quest airlock.

The spacewalkers switched their spacesuits to battery power at 8:15 a.m. EDT to begin the spacewalk, which is expected to last about six and a half hours.

Watch the spacewalk on NASA TV, the NASA app, and the agency’s website.

Hoshide is extravehicular crew member 1 (EV 1), wearing a spacesuit bearing red stripes and using helmet camera #22. Pesquet is extravehicular crew member 2 (EV 2), wearing the unmarked spacesuit and helmet camera #20.

The spacewalkers will begin by working together to build the upper bracket of the modification kit then installing first the left strut followed by the right strut to the mast canister, the base, of one of the solar arrays on the port side of the station’s backbone truss structure. The support bracket will enable future installation of a third of six new International Space Station Roll-Out Solar Arrays (iROSAs) to upgrade one of the station’s eight power channels. Known as 4A, the channel provides partial power to the U.S. Laboratory, the Harmony module, and the Columbus module.

This is the fourth spacewalk for Hoshide, the sixth spacewalk for Pesquet, and the station’s 244th spacewalk in support of assembly, maintenance, and upgrades.

International Astronauts Complete Power System Mods Spacewalk

Mark Garcia Posted on September 12, 2021

Astronauts Akihiko Hoshide of the Japan Aerospace Exploration Agency (JAXA) and Thomas Pesquet of ESA (European Space Agency) have concluded the first spacewalk conducted by two international partner astronauts out of the International Space Station’s Quest airlock at 3:09 p.m. EDT, after 6 hours and 54 minutes.

Hoshide and Pesquet successfully assembled and attached a support bracket in preparation for future installation of the orbiting laboratory’s third new solar array. NASA is augmenting six of the eight existing power channels of the space station with new solar arrays to ensure a sufficient power supply is maintained for NASA’s exploration technology demonstrations for Artemis and beyond as well as utilization and commercialization.

The crew also replaced a device that measures the electrical charging potential of the arrays and associated surfaces in its vicinity, called a floating point measurement unit, on a separate truss section. The new device was powered on successfully.

This was the fourth spacewalk for Hoshide, the sixth for Pesquet, and the 12th spacewalk this year. Hoshide has now spent a total of 28 hours and 17 minutes spacewalking, and Pesquet’s total spacewalking time is 39 hours and 54 minutes. Space station crew members have now spent a total of 64 days, 5 hours, and 54 minutes working outside the station conducting 244 spacewalks in support of assembly and maintenance of the orbiting laboratory.

In November 2020, the International Space Station surpassed its 20-year milestone of continuous human presence, providing opportunities for unique research and technological demonstrations that help prepare for long-duration missions to the Moon and Mars and also improve life on Earth. In that time, 244 people from 19 countries have visited the orbiting laboratory that has hosted nearly 3,000 research investigations from researchers in 108 countries and areas.
