Two astronauts checked in with ground engineers today after completing the second of three spacewalks yesterday that are planned for this month. Meanwhile, a Russian cargo ship stands at its launch pad ready to blast off Thursday morning on a short delivery trip to the International Space Station.

Commander Randy Bresnik and Flight Engineer Mark Vande Hei called down to Mission Control today to discuss the elements of Tuesday’s successful spacewalk. During the excursion, they began the lubrication process on the Canadarm2’s newly-installed latching end effector and swapped out a degraded video camera. Today, the spacewalkers are servicing their spacesuits’ water system and recharging the batteries.

Bresnik will conduct another spacewalk Oct. 18 with NASA astronaut Joe Acaba to finalize the servicing on the Canadarm2 robotic arm. The duo will also perform some electrical maintenance work and replace another degraded video camera. NASA TV will broadcast the third and final spacewalk on Oct. 18 beginning at 6:30 a.m.

Three tons of food, fuel and supplies are loaded inside a Russian resupply ship (ISS Progress 68) ready to lift off to the orbital complex Thursday at 5:32 a.m. The 68P will take just two orbits around Earth and dock to the station less than three-and-a-half hours later. This will be the shortest delivery mission for a Progress mission which usually takes a near six-hour trip, and in the past has taken up to two days to assist in the resupply of the complex.

Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA completed a 6 hour, 26 minute spacewalk at 2:22 p.m. EDT. The two astronauts lubricated components of the new latching end effector they installed in the previous spacewalk on the Canadarm2 robotic arm and replaced a faulty camera system.

They also completed a variety of additional tasks, including replacing a smudged lens cover and removing two handrails from outside the tranquility module in preparation for a future wireless antenna installation.

This was the second of three spacewalks planned for October. Bresnik will also lead the next spacewalk Oct. 18 joined by Flight Engineer Joe Acaba to continue the lubrication of the new end effector and to replace another camera system on the Destiny Lab.

Today’s spacewalk was the fourth for Bresnik’s career and the second for Vande Hei. The Oct. 18 spacewalk will mark the third of Acaba’s career.

Two NASA astronauts switched their spacesuits to battery power this morning at 7:56 a.m., EDT aboard the International Space Station to begin a spacewalk planned to last about 6.5 hours. Live coverage is available on NASA Television and the agency’s website.

Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA will lubricate components of the new latching end effector they installed on the Canadarm2 robotic arm in their first excursion Oct. 5. They will also replace a faulty camera system in the 204th spacewalk in support of assembly and maintenance in station history. This is the fourth spacewalk of Bresnik’s career and the second for Vande Hei.

A third spacewalk to continue the lubrication of the new end effector and to replace another camera system on the Destiny Lab is planned for Bresnik and Flight Engineer Joe Acaba of NASA Oct. 18.

Spacewalkers Going Outside Second Time in Less Than a Week

Spacewalkers Mark Vande Hei and Randy Bresnik
Spacewalkers Mark Vande Hei and Randy Bresnik are pictured Oct. 5, 2017, working outside the International Space Station.

Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA will head outside the International Space Station at approximately 8 a.m. EDT Tuesday to begin a 6.5-hour spacewalk. Live coverage will be available on NASA Television and the agency’s website beginning at 6:30 a.m.

During Tuesday’s spacewalk, Bresnik and Vande Hei will lubricate the Canadarm2 Latching End Effectors (LEE) that the spacewalkers replaced Oct. 5. Canadarm2 has two identical Latching End Effectors used to grapple visiting cargo vehicles and payloads, provide data and telemetry to the rest of the Canadian-built Mobile Base System and the unique capability to “walk” from one location on the station’s truss to another. The Canadarm2 grappling mechanism that was replaced last week experienced a stall of its motorized latches last month.

This will be the 204th spacewalk in support of space station assembly and maintenance, and the second of three spacewalks planned for October.

Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA completed a 6 hour, 55 minute spacewalk at 3 p.m. EDT. The two astronauts replaced one of two Latching End Effectors (LEE) on the station’s robotic arm, Canadarm2.

They also accomplished a couple of get-ahead tasks, including removal of the multi-layer insulation from a spare direct current switching unit. They also prepared a flex hose rotary coupler for future use.

This was the first of three spacewalks planned for October. Bresnik will lead the next two, as well. Vande Hei will join him again Oct. 10 with Flight Engineer Joe Acaba joining him Oct. 18.

The second and third spacewalks will be devoted to lubricating the newly installed end effector and replacing cameras on the left side of the station’s truss and the right side of the station’s U.S. Destiny laboratory.

Today’s spacewalk was the third for Bresnik’s career and the first for Vande Hei. The Oct. 18 spacewalk will mark the third of Acaba’s career.
