SARJ particles are definitely ferrous (iron) - they had Peggy take a small sample off the tape from yesterday and used a magnet to test them - all of them moved around on a white sheet of paper following a magnet on the other side.

That's not good. Means something metallic is wearing or being ground down.

Except the MythBusters have never been into space. Now that would be an episode! :laugh:

Robotics ops coming up next - transfer of P6 to SRMS.
Ground will translate the MT during crew off time this morning.
After lunch the handoff back to SSRMS.

Chris, you might like to correct your article. First paragraph of the SARJ section reads "...shuttle is ready to haul up the JAXA modules in the first half of 2007, via STS-123 and STS-124", surely you mean first half of '08

Bad PAO... Why cut from cool movement of arm to uncool movement of bag in Quest?

ApolloLee · « **Reply #26 on:** 10/29/2007 06:15 am »

Now that's cool... Anyone else have Blue Danue Waltz in their head right now?

--snip--
• P6 Handoff:
o At the end of FD6, SSRMS is based on MBS PDGF3 at WS4 grappled to P6 in the
handoff position. SRMS grapples P6 in the handoff position, and SSRMS releases P6
and maneuvers to a position to view MT translation. Then the MT and SSRMS are
translated to WS8 which is required for P6 installation on P5.
o After the Meal, SSRMS re-grapples P6 in the handoff position and SRMS releases P6
and maneuvers to precradle. P6 remains on the SSRMS in the handoff position
overnight.
o According to the flight rules, P6 should be on the SRMS for as short amount of time as
possible in case of an emergency undock.
--snip--

Does anyone know why the SSRMS doesn't just hold on to the truss during the MT translate (i.e. why handoff to the SRMS at all)? Is it a clearance issue or is there a prohibition against this? Seems like a pretty serious limitation for operations when the shuttle is not docked. Also seems like it would be better based on the flight rule desire to have P6 on the SRMS for as short a time as possible.

Too much mass for the MT to safely move.
Unsafe stress on the SSRMS structures and joints.
That's at least 2 reasons that have been given (probably more I haven't read about yet).

SSRMS now ready to ungrapple P6 now that SRMS is latched to the truss.

MKremer · « **Reply #30 on:** 10/29/2007 06:34 am »

SRMS now grappled. Waiting for SSRMS to ungrapple. (Clay's having a bit of trouble with one of the Coupola robotic laptops and needs to troubleshoot before continuing).

SSRMS now ungrappled and backing away from the truss.

I notice in the contents page of the execute package that they appear to have added an inspection of the Port SARJ (unfortunately the details aren't in the published PDF) to tomorrow's EVA.

MSG 068 --- 10A EVA3 Port SARJ Inspect (pdf – Not Distributed)

Not surprising, really, but I guess that this extra task, and the fact that there were deferred tasks from EVA2, makes the T-RAD test on EVA4 even less likely to actually happen... (not that the crew were very keen to do it in the first place, by all accounts).

SSRMS being placed in stow position in preparation for Mobile Base Transporter being moved to worksite 8

Any word on the MT translation?

uko · « **Reply #35 on:** 10/29/2007 10:16 am »

I understand it is complete and everything is looking good.
