00:00:00,000 --> 00:00:07,370
\h        Music.

2
00:00:07,370 --> 00:00:11,710
\h        Before the Solar Dynamics Observatory is allowed to turn its instruments on the sun,

3
00:00:11,710 --> 00:00:15,090
\h        technicians spent months making sure it is up to the task.

4
00:00:15,090 --> 00:00:19,260
\h        SDO, as the mission is known, arrived in Florida on July 9, 2009,

5
00:00:19,260 --> 00:00:23,060
\h        after its construction at Goddard Space Flight Center in Maryland.

6
00:00:23,060 --> 00:00:27,850
\h        Once inside the large clean room at the Astrotech processing facility near Kennedy Space Center,

7
00:00:27,850 --> 00:00:31,940
\h        technicians carefully unpacked the spacecraft from its protective carrier.

8
00:00:31,940 --> 00:00:37,650
\h        After initial testing and processing, the workers deployed SDO's equipment to make sure it would work in space.

9
00:00:37,650 --> 00:00:40,550
\h        First, the high-gain antenna: Once the mission begins,

10
00:00:40,550 --> 00:00:46,700
\h        SDO will shoot hi-res images of the sun and relay the data instantly to a ground station in New Mexico.

11
00:00:46,700 --> 00:00:50,240
\h        Next, the technicians deployed the SDO's     
    twin solar panels that will be called on to

12
00:00:50,240 --> 00:00:52,880
\h         power the craft during its mission.

13
00:00:52,880 --> 00:01:00,040
\h        At Launch Complex-41, SDO was hoisted to the top of a waiting Atlas V rocket on Jan. 26, 2010,
