Yesterday Flickr NASA Johnson published a hi res photo of Kanai in Cupola.Today it is removed. Why?Has someone saved the hi res version?
Could someone explain to me or point to a link describing the main tasks of the next Russian EVA (Russian EVA 44) ?
You have to accomplish a spacewalk during the flight. What is the planned program?- The main task of the output is to change the electronic unit at the antenna of the retransmission system "Luch". There is such a satellite antenna in the Russian segment that was delivered to the ISS along with the Zvezda service module during the assembly of the station. Then it was assumed that in the nearest future, satellite retransmitters "Ray" will appear and through them we will have a direct connection with the Earth. But, unfortunately, these were the 2000s and funding was inadequate, satellites were not created.This antenna idled in space for 17 years, and although it physically works, but the element base there is already outdated. The satellites of the Luch system created today operate on a new element base. Therefore, in order to make the entire retransmission system for the ISS work, it is necessary to change the electronic unit on the antenna - the subscriber relay equipment.The difficulty lies in the fact that when this service module was launched with the antenna, no one thought that it would have to change this unit in space. Therefore, we are going to have a very difficult and jeweled work: we will have to unscrew tens of bolts in thick gloves of the spacesuit, dismantle the block and put a new one. For this, three types of instruments were invented. We will unscrew one, if it does not go - the second, again not - the third. And earlier, during the previous exits, no one has tried to work in the place where the antenna is. I hope that we will do everything and we will have our onboard-to-Earth connection via the Luch retransmission system (currently the Russian segment uses the NASA retransmission system when the ISS is out of line of sight from Russia - TASS comment).Probably, let's start some microsatellitesAlso there are additional works during this exit. In particular, it will be necessary, if time is enough, to disconnect and dismantle the measuring blocks from the experiment "Furnishings" with subsequent disposal by the method of throwing away from the ISS, to take some samples off the cladding of the station.Probably, we will start some microsatellites. They are launched in a certain direction with their hands, and it is necessary that they do not rotate. I plan to go to outer space on February 2."How do you like the new spacesuit?"- In the new spacesuit added automatic temperature control - it's like in cars climate control. Earlier it was necessary to manually make it warmer or colder, depending on which side of the station is at the exit: on the sunny or shady. Now this is all done by the automation, which redistributes the water streams inside a special thermoregulating water suit, put on you under a spacesuit.In the new spacesuit the material of the hermetic shell changed - it seems to have become tougher, well, it needs to go out and work, then I can make a conclusion.
ISS Daily Summary Report – 1/02/2018 Extravehicular Mobility Unit (EMU) Operations: Today, the crew removed the Short Extravehicular Mobility Unit (SEMU) from the Launch Enclosure (SLE) in order to remove the SEMU Soft Stow Covers and SOP Ancillary hardware. The crew also resized EMUs 3008, 3003, and 3004 in preparation for the upcoming EVAs later this month.
