Roscosmos has rescheduled the launch of the Russian Progress 68 cargo spacecraft for Saturday, Oct. 14 at 4:46 am EDT (2:46 p.m. local time in Baikonur). The spacecraft is carrying almost three tons of food, fuel and supplies for the Expedition 53 crew aboard the International Space Station.

Launch coverage on NASA TV will begin at 4:15 a.m. Following a 34-orbit, two-day trip, Progress will arrive at the Pirs docking compartment of the International Space Station for docking on Monday, Oct. 16, at 7:09 a.m., with NASA TV coverage beginning at 6:15 a.m.

In addition, NASA has rescheduled the Expedition 53 crew’s third and final spacewalk in the current series to next Friday, Oct. 20. Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba will begin the spacewalk at approximately 8:05 a.m., and NASA TV coverage will begin at 6:30 a.m.

The tasks for the crew members to conduct have been adjusted. Bresnik and Acaba will replace a fuse on Dextre’s enhanced orbital replacement unit temporary platform; install an enhanced HD camera on the Starboard 1 lower outboard truss; remove thermal insulation on two spare units to prepare those components for future robotic replacement work, if required; and replace a light on the Canadarm2’s new latching end effector installed during the first spacewalk Oct. 5. The final lubrication of the new end effector and the replacement of a camera system on the Destiny Lab will be deferred for a future spacewalk.

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.

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.

The six Expedition 53 crew members gather together in the Destiny laboratory module for a group portrait. From left are astronauts Joe Acaba, Paolo Nespoli and Mark Vande Hei, Commander Randy Bresnik and cosmonauts Sergey Ryazanskiy and Alexander Misurkin.

Sensors are being installed today in the International Space Station to detect neutron radiation. The crew is also setting up a botany study, conducting human research and getting ready for next week’s spacewalk.

Cosmonaut Sergey Ryazanskiy handed over a set of radiation sensors to NASA astronaut Joe Acaba today. Acaba then installed the sensors in the station’s U.S. segment to measure only the neutron radiation levels the orbital lab is exposed to. The data from the Radi-N2 study will help scientists understand the exposure risk to crew members and develop advanced protective measures.

Acaba also continued installing hardware for the Veggie-3 experiment to get the station ready for a new crop of lettuce and cabbage. Flight Engineer Mark Vande Hei strapped himself into the station’s exercise bike for the VO2max experiment that observes physical exertion during a space mission.

A pair of spacewalkers took a look at the procedures they will use Oct. 5 to replace a latching end effector at the tip of the Canadarm2. Vande Hei will join Commander Randy Bresnik for that spacewalk and a second planned for Oct. 10. Acaba will join Bresnik for a third spacewalk set for Oct. 18.
