FOR mode control is lost when extended arm singularity is reached. Reconfiguration in Single joint mode required to return SSRMS to non-singular configuration<\/p>\n \u2018Pre-planning and training are required to develop recovery trajectories to ensure that SSRMS and OBSS remain clear of each other and the arrays. Executing unplanned reconfiguration trajectories in real-time is not a safe thing to do in this particular situation<\/p>\n \u2018Significant uncertainties remain with developing full trajectories that maintain adequate clearances.\u2019<\/p>\n \u2018Maneuvering an EV crew member on the OBSS is very different from maneuvering with EV attached directly to SSRMS. Kinematic and dynamic sensitivity and behavior are not understood at this time. Training is required to develop the intuitive feel for SSRMS behavior in the proposed configuration. <\/p>\n \u2018This requires additional time to plan the maneuvers. Clear rules on how the results of the characterization will affect the execution of the EVA need to be developed.\u2019<\/p>\n Parazynski will be monitored throughout his EVA, by a variety of cameras, mainly onboard Discovery, ensuring he remains at a safe distance from the array during the repair.<\/p>\n \u2018This kind of coordination is not difficult but requires practice and training. Things that seem trivial like camera placement on the different RWS monitors are critical to safe execution and require training to refine,\u2019 noted the presentation, adding that lessons have been learned by the sun obscuring the view of the cameras, as seen during the problematic deployment of the array.<\/p>\n Still a big issue, the \u2018thermal clock\u2019 on the OBSS sensor package continues to be evaluated. The mission\u2019s current high beta angle is believed to be a bonus for the survival of the package, but Flight Day 10 presentations point to this still being evaluated.<\/p>\n \u2018Thermal constraints: OBSS cameras and sensors are not powered when grappled by SSRMS. FD3 and FD5 handoff maneuvers had a 90 minute thermal clock. SAW repair operations using SSRMS and OBSS will violate the 90 minute clock.<\/p>\n \u2018Options for developing thermally favorable positions for OBSS while on SSRMS may be available. Multiple iterations are often required to find those configurations.\u2019<\/p>\n While Late Inspection can still be carried out on the orbiter after undocking, NASA would prefer to have the OBSS available for this operation. Should it appear that the OBSS package would suffer damage during the array repair, an option of carrying out a part-Late Inspection, while docked to the ISS, is being considered.<\/p>\n \u2018Any late inspection requirements would have to be performed prior to the repair EVA if there is uncertainty about the sensors,\u2019 added a presentation, which could be available, now that EVA-4 has been delayed until Saturday.<\/p>\n MMT and Team 4 presentations now uploaded into L2.<\/p>\n See live threads for up-to-the-second live coverage.<\/p>\n L2 members<\/em><\/font>: All documentation and quotes \u2013 from which the above article has quoted snippets \u2013 is available in full in the related L2 sections, updated live.<\/em><\/p>\n **STARLIGHT: NEW STS-117 MISSION REVIEW MUSIC VIDEO** \u2013 STS-118 Mission review video also available.<\/font><\/em><\/font> <\/em><\/font><\/p>\n **ROCK YOU LIKE A HURRICANE: STS-117 MISSION REVIEW MUSIC VIDEO \u2013 AS SEEN BY THE STS-117 CREW!!**<\/font> -.
