NASA News: Final Space Walk Preparation as Cargo Transfers

All’s ready and the astronauts are prepared with their paraphernalia for the final Space walk. But before that, on Friday at 10:40 a.m. EDT, two flight engineers Fyodor Yurchikhin and Alexander Misurkin would be venturing out of the docking compartment and start their walk.

It’s news for the space buffs!! These two astronauts, who’ve been eyeing at the space, would be spending roughly 6.5 hours rigging cables for the future arrival of a “Nauka” Multipurpose Laboratory Module and also installation of an experiment panel. The Russian Laboratory module would launch a Russian Proton rocket. Its purpose is to substitute Pirs.

Preparations!!

The duo would be opening the hatch to the Pira docking compartment. Further, Commander Pavel Vinogradov and Flight Engineer Chris Cassidy would be cloistered to Poisk module and their Soyuz TMA-08M spacecraft.
During the time of the spacewalk, Pavel Vinogradov and Chris Cassidy would be present there. Even the Europe’s Automated Transfer Vehicle (ATV) and Russia’s Progress 52 resupply craft will be stopped during this time.

Space Walk

This is the seventh spacewalk for Yurchikhin and second one for Misurkin. This spacewalk eventually turns out to be 172nd in support of station assembly and maintenance.

Again the duo would be move out of Pirs in order to substitute a laser communications experiment which has a small optical telescope. This telescope would be mounted during a future spacewalk.

Cargo Transfers

Cargo transfers have been perpetuating from “Kounotori-4”. It is Japan’s H-II Transfer Vehicle (HTV-4). Nyberg, Cassidy and Parmitano endeavored for the whole day and utilized the time in removing cargo and configuring packing gear. Finally, they filled the HTV-4 with some junk.

Arrival of HTV-4

After starting the day in Japan’s Kibo laboratory, Nyberg and Cassidy established a sensor and also treated ventilation grilles. The purpose for the same was to gauge the air velocity inside Kibo.

Japanese materials science experiment, Hicari, was also worked upon by the duo. They have already cleaned and removed sample cartridges.

What’s Hicari?

A GLACIER science freezer was installed by Cassidy. It was done into an EXPRESS rack present in the Destiny laboratory. The ultra-cold freezer harbors biological samples for analysis by the scientists on the ground.
