Florida. One hundred members of the general public, representing Morocco, New Zealand, the United Kingdom and 21 U.S. states, in addition to the District of Columbia, attended the two-day event and, for a time, the #nasatweetup hashtag reached #3 on Twitter's trending topics. Launch window The November 2009 launch window of Atlantis, between November 16 and 20, was complicated by the launch of the Mini-Russian Research Module 2 (MRM-2) aboard a Soyuz-U rocket from the Baikonur Cosmodrome in Kazakhstan. Further conflict was caused by Eastern Range constraints with two other satellite launches from the Cape Canaveral Air Force Station, one at the beginning of the shuttle's launch window and the other at the end. The Eastern Range had been reserved on November 14 and 15, 2009, for the launch of the communications satellite Intelsat 14 aboard an Atlas-V rocket. A Delta-IV rocket carrying a Wideband Global SATCOM satellite was also expected to lift off on November 19, 2009. On November 10, 2009, MRM-2 was successfully launched, docking with the ISS on the 12th, while on the same day the Delta-IV rocket team announced that they had delayed their launch to a future date, allowing the shuttle to gain additional launch opportunities at the end of the window if it required. Atlas V's launch with the Intelsat 14 was scrubbed on the 14th due to a technical issue requiring a rollback. The scrub, lasting more than 24 hours, meant that Atlantis also avoided a possible postponement of its launch slipping into November 17, 2009. Shuttle processing Atlantis was towed from its hangar in Orbiter Processing Facility-1 to the Vehicle Assembly Building (VAB) on October 6, 2009, at about 07:00 EDT. The move, known as rollover, was completed at 08:25 when Atlantis arrived in the VAB transfer aisle. Atlantis was initially scheduled to roll out to Launch Pad 39A on October 13, 2009. However, an issue with a crane that was being used to transfer Atlantis for attachment to its external fuel tank and two solid rocket boosters caused a delay in operations forcing the shuttle managers to add extra 24-hours to the rollout preparations. Atlantis rolled out from the VAB to the Launch Complex 39A on October 14, 2009, at 06:38 EDT in a slow drive on the top of the Crawler-transporter. The rollout was completed with the launch platform secured in place at about 13:31 EDT. The final flight readiness
