Пилотируемая тематика тут ни при чем, просто семерочный пакет почти не изменился и добавление третьей ступени снизило тяговооруженность.

1520 GMT (11:20 a.m. EDT)
"This morning we had a very successful launch," NASA launch manager Omar Baez says. "We had a very nominal flight for the first (stage) and both burns of the second stage and we inserted the satellites at about a-tenth-of-a-mile higher than what was targeted. So we are very happy. The Delta 2 performed just perfect."

"The launch and deployment this morning from the Delta 2 rocket went flawlessly. Both satellites are in their expected orbits, both are safe, communicating with the ground station, responding to commands and receiving solar power," said Rear Adm. Joseph Horn, deputy director of the Missile Defense Agency.
1406 GMT (10:06 a.m. EDT)
High definition video of this morning's Delta 2 rocket launch is available for Spaceflight Now+Plus users here.

If you aren't a subscriber, learn more about the service.
1400 GMT (10:00 a.m. EDT)
NASA and the Missile Defense Agency plan to hold a post-launch news conference at 11 a.m. EDT to recap today's ascent and give an update on the state of health for both STSS Demo satellites.
1330 GMT (9:30 a.m. EDT)
This is the 90th consecutive successful Delta 2 rocket launch dating back to May 1997. The Delta 2's overall history since debuting in 1989 has achieved 143 successes in 145 flights.

The next Delta 2 rocket launch will occur from Vandenberg Air Force Base in California on October 8. That mission will deliver the WorldView 2 commercial Earth-imaging spacecraft into orbit for the DigitalGlobe company.
1318 GMT (9:18 a.m. EDT)
"Building on the launch of the STSS ATRR mission in May, I congratulate both the Missile Defense Agency and NASA for the start of a second successful mission that will demonstrate technologies very important to the defense of our nation," said Jim Sponnick, United Launch Alliance vice president, Delta Product Line.

"Exceptional teamwork between, NASA, the 45th Space Wing, the Missile Defense Agency, and ULA Delta 2 team enabled today's successful launch of the STSS Demo mission."
1315 GMT (9:15 a.m. EDT)
T+plus 55 minutes, 18 seconds. SEPARATION NO. 2! The lower satellite in the stack of two Space Tracking and Surveillance System spacecraft has been deployed, completing this morning's launch sequence.
1312 GMT (9:12 a.m. EDT)
T+plus 52 minutes. The second stage is pitching around 180 degrees to the desired position for casting free the second satellite.
1310 GMT (9:10 a.m. EDT)
T+plus 50 minutes, 30 seconds. The Delta 2 rocket is performing a retro maneuver to back away from the satellite it just deployed.
1307 GMT (9:07 a.m. EDT)
T+plus 47 minutes, 49 seconds. SEPARATION NO. 1! The upper satellite in the stack of two Space Tracking and Surveillance System spacecraft has been released into orbit.
1305 GMT (9:05 a.m. EDT)
T+plus 45 minutes. The two STSS Demo satellites are stacked one on top of the other. The separation system will fire to eject the first satellite. The upper stage then backs away and performs a turn to release the second craft that's affixed to the special carrier structure mounted atop the rocket.
1303 GMT (9:03 a.m. EDT)
T+plus 43 minutes, 4 seconds. The second stage has completed its second burn of this launch. In the next minute, the rocket will be maneuvering itself into the proper orientation for deploying the first STSS Demo satellite.
1302 GMT (9:02 a.m. EDT)
T+plus 42 minutes, 32 seconds. The Delta 2 rocket's second stage is firing again. The burn is in progress to place the vehicle into the planned circular orbit.

1301 GMT (9:01 a.m. EDT)
T+plus 41 minutes. The Diego Garcia tracking site located in the Indian Ocean is receiving data from the rocket for transmittal to the launch site.

1300 GMT (9:00 a.m. EDT)
T+plus 40 minutes. The rocket is soaring over the northwestern Indian Ocean, and restart of the second stage engine is just a couple of minutes away.

1257 GMT (8:57 a.m. EDT)
T+plus 37 minutes. The Delta 2 rocket should entering into the Diego Garcia tracking station's coverage zone, restoring a live telemetry link from the vehicle.

1255 GMT (8:55 a.m. EDT)
T+plus 35 minutes. Restart of second stage engine is expected at about T+plus 42 minutes, 30 seconds. The stage will fire for approximately 67 seconds to reach a circular orbit 729 nautical miles high and inclined 58.00 degrees for deployment of the two payloads.
1251 GMT (8:51 a.m. EDT)
T+plus 31 minutes. "We have a tandem launch today, so we have two satellites going up on the same launch vehicle, which is a little bit unusual and complicates mission somewhat. But once we get the birds up on orbit, we'll be using the two satellites together to simulate a constellation of satellites and we'll do this to test the sensor layer for the Ballistic Missile Defense System," said Lt. Col. Matthew Murdough, an MDA representative.

"We have a latch and spring mechanism that will release and the first satellite will separate away and move forward from the second satellite. We actually do a 180-degree flip maneuver with the second stage of the Delta 2 and we release the second satellite in the opposite direction as the first."

1247 GMT (8:47 a.m. EDT)
T+plus 27 minutes, 20 seconds. The vehicle just passed out of range from the Oakhangar tracking site in England. The next station to acquire the rocket's signal will be Diego Garcia in the Indian Ocean for coverage of the second stage restart and deployment of the STSS payloads.
