1545 GMT (11:45 a.m. EDT)
 RANGE NOW 'NO GO' while safety personnel sweep the hazard area off the coast of Cape Canaveral.

1544 GMT (11:44 a.m. EDT)
 The Centaur helium problem appears to be on the ground-side of the system.

1543 GMT (11:43 a.m. EDT)
 The earlier issue about a first stage purge pressure sensor reading has been reviewed and determined to be no concern for launch.

1540 GMT (11:40 a.m. EDT)
 This upcoming test, which should take about five minutes to run, is an effort to determine if there is a leak in the helium system.

1539 GMT (11:39 a.m. EDT)
 HOLD EXTENDED by 10 more minutes, putting launch no sooner than 11:59 a.m. EDT.

1539 GMT (11:39 a.m. EDT)
 The team is going to stop flow to the Centaur while running some tests.

1535 GMT (11:35 a.m. EDT)
 FIVE MORE MINUTES have been inserted into this countdown hold, delaying launch to 11:49 a.m. EDT.

1533 GMT (11:33 a.m. EDT)
 NASA says the helium system charge cycle rate being seen today is being compared with the rate recorded during the countdown dress rehearsal a couple of weeks ago, plus looking at the ground-side of the system and performing a leak check, a spokesman says.

1530 GMT (11:30 a.m. EDT)
 ANOTHER HOLD EXTENSION has been added, pushing launch time back to 11:44 a.m. EDT.

1529 GMT (11:29 a.m. EDT)
 Today's launch opportunity extends to 12:43 p.m. EDT, so there's plenty of time for engineers to work through these technical issues that popped up late in the countdown.

1526 GMT (11:26 a.m. EDT)
 HOLD EXTENDED by five minutes to review these technical issues. So that put launch no sooner than 11:39 a.m. EDT.

1525 GMT (11:25 a.m. EDT)
 Liftoff likely will be delayed at least a few minutes.

1525 GMT (11:25 a.m. EDT)
 The Juno spacecraft's transfer to internal power will be delayed while the helium issue is assessed.

1524 GMT (11:24 a.m. EDT)
 The anomaly team is starting a discussion about higher the expected cycles of Centaur helium system charges.

1522 GMT (11:22 a.m. EDT)
 The launch team is looking at the momentary first stage purge pressure sensor reading. But that doesn't appear to be an issue.

1559 GMT (11:59 a.m. EDT)
 Standing by to resume the pre-flight activities that were placed in an extended hold while engineers sorted out a couple of technical issues and the Range to swept the hazard box again.

1557 GMT (11:57 a.m. EDT)
OFFICIAL NEW LAUNCH TIME has been established for 12:13 p.m. EDT.

1553 GMT (11:53 a.m. EDT)
 The Atlas 5 rocket now stands ready for launch, pending a final OK from the Range that the hazard area is clear.

1552 GMT (11:52 a.m. EDT)
 The anomaly team says the testing determined the excessive charging of the Centaur helium system is being caused by a ground-side problem. Engineers are switching the charging to a backup system, clearing the way for launch.

1545 GMT (11:45 a.m. EDT)
 FURTHER HOLD ORDERED lasting five more minutes, meaning the launch time has slipped to 12:04 p.m. EDT.
