With the ASAP (Aerospace Safety Advisory Panel) noting their approval \u2013 both \u201cinformally and formally\u201d \u2013 from a safety standpoint, the main assessment of STS-135\u2032 safety was tasked to the NASA Engineering and Safety Center (NESC), per Senate refinements to the FY2011 budget proposal.<\/p>\n
\u201cThe House authorization bill added the additional flight to mirror the Senate bill. There is some difference in how we would pay for it so everything isn\u2019t locked down yet but we are continuing with the planning,\u201d added one managerial overview on the latest Staff Senior Notes (L2).<\/p>\n
\u201cThe Senate bill asked the NESC to do an independent assessment of the STS-135 flight from a safety perspective.\u201d<\/p>\n

The NESC safety assessment overview was presented to managers at the Johnson Space Center (JSC) on Friday, with pre-emption of STS-135 taking the next step seen via a note from SSP manager John Shannon.<\/p>\n
\u201cA CR (Change Request) will be put out (Friday) to slide the STS-335 launch date to June 28, 2011, which is consistent with what a STS-135 launch date would be,\u201d noted Mr Shannon on the latest Shuttle\/Standup\/Integration report (L2). \u201cIt keeps us all on the same milestones for that.\u201d<\/p>\n
By Friday afternoon, notes of a meeting between SSP and ISS management confirmed the initiation of STS-135 as a \u201cReal Planned Mission\u201d, one which will go through the key Flight Definition and Requirements Directive (FDRD) process \u2013 the key baselining element for a mission.<\/p>\n

The mission outline matches with previous evaluations of late, with a full 16 rack MPLM, and an LMC carrier that will be configured to accommodate the return of the failed External Thermal Control System (ETCS) Pump Module \u2013 to allow for evaluations on the ground into the root cause failure on the ISS.<\/p>\nA four person crew allows for the utilization of the Soyuz \u201cLON\u201d plan, which \u2013 in the highly unlikely event Atlantis was unable to return to Earth \u2013 would result in the STS-135 crewmembers returning on two Soyuz vehicles, staggered over their scheduled return dates, with Expedition crewmembers handing over their seats in return for an extended stay on the ISS.<\/p>\n
The mission duration is being planned as 11+1+2, with one EVA \u2013 planned to be conducted by ISS crewmembers as a Stage EVA during the docked phase of the STS-135 mission \u2013 although Friday\u2019s meeting spoke of a consideration in assigning one STS-135 crewmember for EVA tasks, to enhance the flexibility of the mission options.<\/p>\n
At present, Soyuz TMA-22 is set to launch to the ISS in September, 2011 for an ISS crew rotation. Another Soyuz is set to launch in November, 2011 \u2013 which will be another installment of a new series of the veteran vehicle, designated Soyuz TMA-03M.<\/p>\n
According to the meeting notes, crew selection will take place on September 14, with training \u2013 or crew loading \u2013 to begin on September 27. The June 28, 2011 launch date moves the mission four days to the right of previous evaluations.<\/p>\n

Payload planning will continue throughout the coming weeks and months via meetings with ISS and Shuttle managers, who will work out the best utilization of Atlantis\u2019 upmass, with notes referring to the potential addition of the Goddard Space Flight Center (GSFC) payload R2D2, and DTO (Detailed Test Objective) 703 STORRM (Sensor Test for Orion RelNav Risk Mitigation).<\/p>\nWith Change Requests (CR) being added into the system, Atlantis will remain with a STS-335\/135 call sign \u201cfor now\u201d until the mission has been put through the baselining requirements \u2013 likely to be reviewed at upcoming Program Requirements Control Board (PRCB) meetings.<\/p>\n
STS-135 \u201cfinal\u201d approval, from a manifest standpoint, will come at the political level via the required funding allocation in the NASA budget. With both the Senate and House refinements to the FY2011 budget proposal, the decision was technically passed back to NASA, and the safety assessments, which were undertaken \u2013 positively \u2013 on Friday.<\/p>\n","protected":false},"excerpt":{"rendered":"
Atlantis has gained one final mission, flying STS-135 to the International Space Station (ISS), with a launch date targeting June 28, 2011. Pending required funding allocation, Atlantis will carry a packed Multi-purpose Logistics Module (MPLM) and a Lightweight Multi-Purpose Carrier (LMC), on a 11+1+2 mission with a four person crew.
