Some questions on iss Russian  segment

1) what Is the warranty of iss spare elbow joint on iss mrm module I need to know that to see the final period till which it can be used in case actual Era gets some problems

2) is MLM radiator and MLM heat exchanger same

3) how will Era position mlm airlock from mrm to nauka as it has only one frgf grapple fixture when Era grapple fixtures  are different

4)is Era portable  workpost and nauka means of attachment of large payloads different. If yes like as shown in the image below then is there a timeline for transferring Era portable workpost  from mrm to nauka
and  installation it. And which Progress MS delivered the means of attachment of large payloads.

Been reading about ISS this month, so have a few questions   ;)
1) Now that we have an extra member due to Crew Dragon, do we know how many astronaut-hours are spent on science vs maintenance per week?
In 2014, it was around 40 hours/week for USOS. (Slide 14 in https://www.nasa.gov/sites/default/files/files/NACRS_ISSResourceOverview_022014T.pdf)
2) Are there any plans to add International Docking Adapter to Prichal?
3) I want to learn more about the life support systems, are there any books about this?
4) Are daily schedules of astronauts published anywhere? (It was till 2014, but couldn't find the link now)

 I am not sure where to post this, but why am I not seeing anything here about NASAWatch's new story about NASA cutting back on PA coverage of the ISS? Seems like an important topic!

Will Strela no longer be needed once the ERA is operational? Also, can the ERA be equipped with a portable foot restraint?
Thx

they will be supplementary then a notable thing is the era grapple fixtures are only on nauka and prichal so maybe strela are needed for other modules in ros segment and for ERA foot restraint it is already on iss transported with rassvet as mlm outfitting on sts-127 like the nauka airlock, radiator and era spare elbow joint. Hope this helps out.

Yes, their use will lessen but is not fully eliminated. The Strela booms can be mounted on Nauka as was a proposed plan at one point when the original ROS proposal came about. ERA range can be extended by installing additional grapple fixtures on the rest of ISS RS. Even ERA grapple fixtures on the Columbus module was once considered as a part of an earlier plan before it was bumped to the Russian Segment as a barter for Russian technology transfer for the ATV programme, etal.

Nanoracks told me that they come back on Dragon cargo missions to be used again, some of been to space more than 5 times!

Does anyone happen to know anything about a new piece of station equipment called a Mini Pump Module? I've seen it referred to a few times in sources from ~2021, but I can't find any explanation of what it is or when it would be launched.

ISS crew is carefully selected and trained, so if any of them deplore CubeSats, they keep their thoughts to themselves.  :)

The sources I'm looking at, incidentally:

 - The ISS Daily Summary Report for 1 February 2021, which lists "Imagery of Mini Pump Module worksite area" as a get-ahead performed by Hopkins and Glover during EVA-70

https://blogs.nasa.gov/stationreport/2021/02/01/

 - This 2021 tweet from Koichi Wakata about doing a development run in the NBL:

https://twitter.com/Astro_Wakata/status/1425285580263415810

 - NASA's FY2022 Budget Estimates document, which mentions it in the ISS section on page 205 / SO-10: "In the vehicle area, ISS is poised to extend the Functional Cargo Block through 2024; deploy the large equipment launch carrier development Ammonia Tank Assembly, BCDU, and Mini-Pump Module; and continue spares procurements for cupola scratch panes, heat exchanger parts, tanks, pump assembly, catalytic reactor, hydrogen dome, and ancillary components and parts."

The Pump Module is the External Active Thermal Control System pump and valve control ORU.

The Mini Pump Module contains upgrades to the ORU based on the years of operational history and failures that have occurred.

Fun fact: the Mini Pump Module used to be called the EPCVP (External Pump and Control Valve Package). They changed the name to Mini Pump Module because everyone kept tripping over the old acronym.

Does all of the USOS modules share the same end cone design and therefore dimensions? From photos it does look like that the general design is the same, with only minor module specific changes like EVA handrail stanchion bolt hole locations. If this is correct, does anyone have their dimensions, length, minor diameter and major diameter?
