ISS U.S. EVA-48 - February 16, 2018
« on: 01/27/2018 01:10 PM »
I don't see a thread yet for Monday's EVA so here it is.  With word in other threads that this EVA will return the degraded LEE to the arm because the replacement has only one functional command string, I'm wondering if there will be enough time to bring in the LEE planned for return on Dragon or will another EVA be required? ???

ISS EVA47/48: Assuming no surprises over the weekend -- the new LEE-B will be detached and mounted on a stowage deck; its camera will be removed and attached to the original LEE mechanism; the old unit then will be re-attached to the robot arm; no other LEE work is planned

After extensive troubleshooting by teams from NASA and the Canadian Space Agency (CSA), the decision was made by space station managers to use the scheduled Jan. 29 spacewalk to reinstall the LEE removed on the Jan. 23 spacewalk to restore fully redundant capability to the robotic arm

But...

Quote
CSA and its robotics specialists are continuing diagnostics over the weekend to gain additional insight. If data is obtained that could be used to solve the issue, Mondayís spacewalk could be postponed

EVA47/48: A test Saturday night confirmed the patch worked and the arm is now deemed fully operational; a second spacewalk to move a faulty grapple fixture inside for return to Earth, and to relocate another outside the station, has been deferred to mid February

ISS Daily Summary Report Ė 1/29/2018

SSRMS LEE status:  During USOS EVA 47, LEE serial number 201 was removed from the SSRMS and replaced with the spare LEE, serial number 204.  After the installation, ground teams were unable to bring LEE 204 to an operational state on primary power.  Redundant power operated as expected.  Due to this anomaly, plans were put in place to swap the LEEs back and place LEE 201 on the SSRMS as it was before.  Over the weekend, ground teams were able to install diagnostic software that identified the root cause as a faulty initial force reading.  Ground and on orbit testing confirmed the root cause, and also confirmed the ability to operate the LEE on the prime power string if the LEE was already grappled to a fixture.  A software update is being developed to resolve the issue, and is targeted for uplink in two weeks, at which point it is expected that the LEE currently installed on the SSRMS (LEE 204) will be fully operational.

That explains the 2 week delay to EVA-48.  It lets MDA/CSA finish the fix and upload it.  If the fix doesn't end up working, they'll still be able to revert the LEEs to the preEVA-47 situation in a single spacewalk.  So, the delay is just however long it will take the software teams to get the fix worked out and through testing, plus maybe a few days for on-orbit testing of the patched LEE.  That's more fast work by all the ROBO teams after they already were able to hack together the diagnostic to find the fault in the first place.  They may not often get the spotlight like the astronauts do, but engineering support is awesome.  Keep up the great work guys/gals!

MEDIA ADVISORY M18-025
NASA TV to Air US Spacewalk at the International Space Station
 

Two astronauts will venture outside the International Space Station Thursday, Feb. 15, to move components for the stationís robotic system into long-term storage. Live coverage of the spacewalk will begin at 5:30 a.m. EST on NASA Television and the agencyís website.

Expedition 54 Flight Engineers Mark Vande Hei of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency are scheduled to begin the spacewalk at 7:10 a.m. and finish about 1:40 p.m.

The two spacewalkers will move a Latching End Effector (LEE), or hand, for the Canadian-built robotic arm, Canadarm2, from a payload attachment on the stationís Mobile Base System rail car to the Quest airlock. This LEE was replaced during an Expedition 53 spacewalk in October 2017, and will be returned to Earth to be refurbished and returned to the orbiting laboratory as a spare.

They also will move an aging, but functional, LEE that was removed during a Jan. 23 spacewalk from its temporary storage outside the airlock to a long-term storage location where it will be available as a spare part for the Mobile Base System, which is used to move the arm and astronauts along the stationís truss structure.

The spacewalk originally was scheduled Jan. 29 but was postponed when a new LEE installed during the Jan. 23 spacewalk encountered startup issues. Those issues were resolved Jan. 27 through software updates written by Canadian Space Agency robotics specialists.

The spacewalk will be the 208th in support of space station assembly and maintenance and the third station spacewalk this year. The spacewalk will be the fourth spacewalk in Vande Heiís career and the first for Kanai, who will become the fourth Japanese astronaut to walk in space. Vande Hei will wear the suit bearing the red stripes and Kanaiís suit will have no stripes.
