Whakakiia te rerenga e whai ake nei: I tīmata te whakakii i te "Discovery's" External Tank hei whakarite mo te whakarewatanga i te 11:50 GMT. I te 12:50, i whakapumautia ko nga whakamatautau tuatahi i runga i nga miihini Engine Cutoff (ECO) i roto i te Tank o waho i angitu. Ko nga ngoikoretanga o te pūoko ECO i whakaroa i te maha o nga whakamatau whakarewatanga Shuttle o mua ake nei, a ko STS-124 te miihana tuatahi ki te whakamahi i te tank whakarereke, i hangaia hei whakakore i aua hapa. I te wā i tīmata ai te whakakii hinu, i matapae ngā kaitohutohu huarere he 80 ōrau pea o ngā āhuatanga e manakohia ana i te wā kua whakaritea hei whakarewa. Kua oti te whakakii, ā, ka tīmata te whakakii i te pūkaha cryogenic, i te 15:36. Hei taapiri ki nga whakarereketanga o te ECO sensor, koinei te miihana tuatahi ki te whakamahi i te Tank o waho i hangaia i muri i te putanga o te ECO.
Ko te aitua o "Columbia" i te tau 2003, no reira ko te tank tuatahi i hangaia nga whakapainga ahuru katoa ki roto, kaua ki te whakahou.
