Sources are noting that Marshall Space Flight Center (MSFC) have seen their request for a design change to the External Tanks dismissed by managers at the Johnson Space Center during today\u2019s heated PRCB (Program Requirements Control Board) meeting. <\/p>\n

Meanwhile, seperate sources are claiming John Muratore, Manager for Shuttle Systems Engineering and Integration, has been re-assigned to a position that has no influence on Shuttle decisions.

Remaining issues with the tank comes as a surprise, following encouraging wind tunnel testing \u2013 which is still on-going \u2013 on the modified ET test article.<\/font> <\/p>\n

The ice\/frost ramps appear to be the focus of attention again, with further work on \u2018shaving\u2019 the ramps down being part of the Wind Tunnel process. <\/font><\/p>\n

\"\"A small section of foam did liberate from the ice\/frost ramp during a 30 second high aerodynamic pressure run, although that was believed to be over 1000 psf \u2013 much higher than a Shuttle can expect to encounter during ascent.<\/font><\/p>\n

To aid the reduction in foam shedding, NASA recently confirmed they would fly STS-121 with a \u2018Low Q\u2019 mission profile, which will keep the stack below 735 psf during the ride uphill. Wind Tunnel tests below 735 psf encountered no problems during evaluations.<\/font><\/p>\n

It is possible, though not confirmed, that MSFC requested that the ice\/frost ramps on all future External Tanks, including ET-119 \u2013 currently awaiting Discovery\u2019s arrival for mating in the VAB (Vehicle Assembly Building) \u2013 undergo the extra \u2018shaving down\u2019 as undertaken at the wind tunnel tests.<\/font><\/p>\n

\"\"<\/font><\/em>However, it is understood that during today\u2019s PRCB the recommendation was rejected, with the decision to proceed with flying the tank \u2018as is.\u2019<\/font><\/p>\n

Discovery is currently schedule to fly this July on STS-121 \u2013 the second of two test flights prior to the re-start of International Space Station (ISS) assembly flights.<\/p>\n

A re-design would have likely led to a 12-18 month downtime period for the Shuttle fleet, a highly undesirable option for the Program.<\/p>\n
