Spacesuits and eye checks filled the schedule on Tuesday as the Expedition 71 crew gears up for a trio of spacewalks planned for this month. The International Space Station residents also kept their research and lab maintenance duties while unpacking a new cargo ship.

NASA Flight Engineers Matthew Dominick and Mike Barratt started their morning inside the Quest airlock preparing suits and equipment for upcoming spacewalks. The duo then joined fellow NASA astronauts Tracy C. Dyson and Jeanette Epps after lunchtime for a spacewalk conference with specialists on the ground. Afterward, Dyson and Dominick partnered together organizing and configuring a variety of spacewalk tools in Quest. NASA will announce the spacewalk details and spacewalkers in an upcoming media advisory and news briefing.

Earlier, Epps powered on a pair of Astrobee robotic free flyers for an operations test. She also set up a pair of Kubik research incubators inside the Columbus laboratory module. At the end of the day, Epps gathered in the Harmony module with Barratt and Dominick for eye checks using a medical imaging device viewing the cornea, retina, optic nerve.

Station commander and Roscosmos cosmonaut Oleg Kononenko who is on his fifth mission aboard the orbital outpost has accumulated 1,000 days in microgravity as of June 4. The previous record holder was cosmonaut Gennady Padalka who held the record since Sept, 11, 2017, when he landed on Earth completing the Expedition 44 mission and gaining 879 cumulative days in space.

Kononenko joined Flight Engineer Nikolai Chub on Tuesday and continued offloading some of the three tons of cargo packed inside the recently arrived Progress 88 cargo craft. Fellow cosmonaut Alexander Grebenkin wrapped up an experiment session and stowed hardware that images Earth’s upper atmosphere in ultraviolet wavelengths. Afterward, he studied ways international crews and mission controllers can improve communications to inform crew training and ensure mission success.

Teams at NASA and Boeing confirmed Monday the company’s Starliner spacecraft, ULA (United Launch Alliance) Atlas V rocket, and ground support equipment are healthy and ready for the next launch attempt. The first Starliner flight with NASA astronauts Butch Wilmore and Suni Williams, known as NASA’s Boeing Crew Flight Test, is targeted to liftoff at 10:52 a.m. EDT Wednesday, June 5, to the International Space Station for about a one week stay aboard the microgravity laboratory.

The Expedition 71 crew kicked off Monday with spacesuit work and cargo operations aboard the International Space Station. Back on Earth, mission managers are targeting June 5 for the launch of Boeing’s Starliner spacecraft on NASA’s Crew Flight Test.

Four NASA astronauts spent much of Monday in the Quest airlock checking out spacesuits and reviewing procedures for a trio of spacewalks targeted to take place in June. Flight Engineer Mike Barratt started the work as he powered up the spacesuits, cleaned cooling loops, and serviced suit components throughout the day. Flight Engineer Tracy C. Dyson assisted Barratt with the suit job then trained on the suit safety systems and jet packs that would be used to maneuver back to the station in the unlikely event of an emergency.

Flight Engineer Matthew Dominick also participated in the spacesuit and jet pack safety training. He also joined Flight Engineer Jeanette Epps and reviewed standard spacewalk procedures such as suiting up, exiting and entering Quest, safety steps, and communication protocols. NASA will announce the spacewalk details and spacewalkers in an upcoming media advisory and news briefing.

On Saturday, June 1, a Roscosmos Progress 88 cargo craft docked to the space station’s Poisk module packed with about three tons food, fuel, and supplies. Cosmonauts Oleg Kononenko and Nikolai Chub monitored Progress’ arrival then spent a portion of the weekend and all-day Monday unloading the new cargo. Kononenko also replaced communications gear in the Zvezda service module while Chub set up and photographed a new space physics investigation.

Cosmonaut Alexander Grebenkin pointed a camera outside a station window toward Earth today and photographed landmarks for a pair of Earth observation studies. At the end of the day, Grebenkin installed hardware to image Earth’s atmosphere in ultraviolet wavelengths. Researchers use the imagery to understand natural events and man-made impacts on Earth’s surface and atmosphere.

Teams at NASA and Boeing confirmed Monday the company’s Starliner spacecraft, ULA (United Launch Alliance) Atlas V rocket, and ground support equipment are healthy and ready for the next launch attempt. The first Starliner flight with NASA astronauts Butch Wilmore and Suni Williams, known as NASA’s Boeing Crew Flight Test, is targeted to liftoff at 10:52 a.m. EDT Wednesday, June 5, to the International Space Station for about a one week stay aboard the microgravity laboratory.

Teams at NASA and Boeing confirmed Monday the company’s Starliner spacecraft, ULA (United Launch Alliance) Atlas V rocket, and ground support equipment are healthy and ready for the next launch attempt. The first Starliner flight with NASA astronauts Butch Wilmore and Suni Williams, known as NASA’s Boeing Crew Flight Test, is targeted to liftoff at 10:52 a.m. EDT Wednesday, June 5, to the International Space Station for about a one week stay aboard the microgravity laboratory.

Work at the launch pad at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida was completed June 2 to change out and test a failed power distribution source that halted a launch attempt on June 1. The Starliner mission management team reviewed multiple aspects of the replacement and troubleshooting steps and polled “go” to proceed during a detailed session as they continue to prep the teams and hardware for the June 5 opportunity.

“I really appreciate all the work by the NASA, Boeing, and ULA teams over the last week,” said Steve Stich, manager of NASA’s Commercial Crew Program. “In particular, the ULA team worked really hard to quickly learn more about these issues, keep our NASA and Boeing teams informed, and protect for this next attempt. We will continue to take it one step at a time.”

The weather forecast continues to call for favorable conditions, with U.S. Space Force meteorologists from the 45th Weather Squadron predicting a 90% chance of acceptable conditions at launch time. The ascent corridor and onshore winds weather also is forecast to be acceptable in the unlikely case of an emergency abort during the launch.

Wilmore and Williams continue preparing for launch with proficiency training. The two remain quarantined at Kennedy Space Center in Florida ahead of liftoff.
