(CHEERS) 2 00:00:04.705 --> 00:00:10.310 Underwater mission rehearsals 3 00:00:10.310 --> 00:00:16.850 >>COMMS: 4, 3, 2, 1 and liftoff of space shuttle 4 00:00:16.850 --> 00:00:20.621 Atlantis the final visit to enhance the vision of Hubble, 5 00:00:20.621 --> 00:00:24.091 into the deepest grandeur of our universe! 6 00:00:24.091 --> 00:00:26.827 >>JOHN GRUNSFELD: This is a really tremendous adventure 7 00:00:26.827 --> 00:00:30.364 that we've been on, a very challenging mission, Hubble 8 00:00:30.364 --> 00:00:34.201 isn't just a satellite, it's about humanity's quest for 9 00:00:34.201 --> 00:00:38.138 knowledge. And Arthur C. Clark said, 'the only way of finding 10 00:00:38.138 --> 00:00:42.142 the limits of the possible is by going beyond them into the 11 00:00:42.142 --> 00:00:46.546 impossible,' and on this mission we tried some things that many 12 00:00:46.546 --> 00:00:51.184 people said was impossible: fixing STIS, repairing ACS, 13 00:00:51.184 --> 00:00:55.155 achieving all the content that we have in this mission. But 14 00:00:55.155 --> 00:00:00.000 we've achieved that and we wish Hubble the very best.
