1 00:00:00,000 --> 00:00:07,940 \h Music. 2 00:00:07,940 --> 00:00:15,950 \h On Dec. 14, 2009, A United Launch Alliance Delta II rocket carried NASA's Wide-field Infrared Survey Explorer, 3 00:00:15,950 --> 00:00:19,830 \h or WISE, space telescope into a high polar orbit. 4 00:00:19,830 --> 00:00:25,210 \h WISE lifted off from Space Launch Complex-2 at Vandenberg Air Force Base in California 5 00:00:25,210 --> 00:00:29,990 \h beginning its 10-month mission to map the entire sky in the infrared. 6 00:00:29,990 --> 00:00:37,150 \h Preparations for launch started earlier in the year when WISE's builder, Ball Aerospace & Technologies Corp., in Boulder, Co., 7 00:00:37,150 --> 00:00:42,090 \h shipped the spacecraft to the Astrotech payload processing facility at Vandenberg. 8 00:00:42,090 --> 00:00:47,010 \h During the months of August, September and October the spacecraft was uncanned, 9 00:00:47,010 --> 00:00:52,460 \h uncovered and moved to a clean room for testing, weighing and balancing. 10 00:00:52,460 --> 00:00:59,840 \h Meanwhile, at Space Launch Complex-2, build-up of the Delta II began on Oct. 19 with the hoisting of the first stage onto 11 00:00:59,840 --> 00:01:04,240 \h the launcher platform, shortly followed by the interstage section. 12 00:01:04,240 --> 00:01:08,980 \h Once the first and interstage sections were secured, workers attached the three solid rocket 13 00:01:08,980 --> 00:01:14,350 \h boosters around the base and then lifted the second stage section into position. 14 00:01:14,350 --> 00:01:21,700 \h By the end of October, the rocket was complete and testing began on its Tracking and Data Relay Satellite transmitter. 15 00:01:21,700 --> 00:01:27,570 \h A demanding workload followed in November as technicians tested the rocket's propellant and guidance control systems, 16 00:01:27,570 --> 00:01:31,920 \h in addition to performing first stage leak checks. 17 00:01:31,920 --> 00:01:36,030 \h At Astrotech, work continued with loading of the cryogenic hydrogen that will keep the 18 00:01:36,030 --> 00:01:41,740 \h spacecraft's infrared telescope super-cold during its months of observations. 19 00:01:41,740 --> 00:01:49,930 \h After one final week of testing, technicians gingerly lowered a transportation canister over WISE for its move to the launch pad. 20 00:01:49,930 --> 00:01:56,130 \h Then, the 1,460-pound spacecraft was lifted atop the Delta II rocket. 21 00:01:56,130 --> 00:02:00,530 \h By the end of the month, an integrated electrical test was conducted to ensure the 22 00:02:00,530 --> 00:02:04,430 \h two crafts communicated with each other and with mission control. 23 00:02:04,430 --> 00:02:10,280 \h In a clean room environment, the spacecraft was carefully encased in its protective shell, called a fairing. 24 00:02:10,280 --> 00:02:17,080 \h The two-part fairing protects the spacecraft during the harsh environment of liftoff, and fell away once it reached orbit. 25 00:02:17,080 --> 00:02:23,590 \h Technicians at the launch pad continued mechanical, electrical and avionics system checkouts of the rocket, 26 00:02:23,590 --> 00:02:28,730 \h while cooling of the spacecraft's cryogenic systems continued until liftoff.
