Early indications on processing reports noted that it would not be a constraint to rollover. <\/p>\n<p>\u2018Orbiter jackdown\/weight\/CG (Center of Gravity) completed yesterday (Thursday); OTS (Orbiter Transporter System) Operations scheduled for today,\u2019 noted Friday\u2019s processing report. <\/p>\n<p>\u2018Picked up (problem), RMLG (Right Main Landing Gear) strut has higher than acceptable leak rate (allowed 1 drip\/hour, currently seeing 1 drip every 20 seconds).<\/p>\n<p>\u2018Gear was cycled five times last night with the following results: 1st cycle no drips. 2nd cycle 1 drip. 3rd cycle 5 drips. 4th cycle no drips. 5th cycle 1 drip. Strut is now extended with diaper installed. This issue may delay transporter operations, but should be no threat to rollover.\u2019<\/p>\n<p>However, further testing showed the leak was unacceptable, requiring repairs. This will carried out on Monday or Tuesday, leading to a slight delay to the rollover date, possibly by a couple of days.<\/p>\n<p>\u2018All work for OV 103 (Discovery) has been cancelled due to main landing gear seal work,\u2019 noted information on Saturday. \u2018Repair estimated Tuesday or Wednesday.\u2019<\/p>\n<p>The launch date&nbsp;should not be affected unless they require the seals to be changed out \u2013 as there is remaining contingency in the current STS-120 flow, which is ultimately targeting a launch to the International Space Station (ISS) in a launch window that opens on October 23.<\/p>\n<p>\u2018Payload bay doors closed in OPF.
