Virtual Launch Control Center - New Horizons
 
Archived coverage of the scrubbed launch attempt of New Horizons on January 17, 2006.

All times are in EST unless otherwise stated.

The Virtual Launch Control Center was activated at 11:00 a.m.

The Virtual Launch Control Center was deactivated at 3:27 p.m.

3:22 p.m. - The launch vehicle is being safed at this time for a launch attempt tomorrow afternoon. The clock will be reset to T-4 minutes and holding at this time. Tomorrow's window will open at 1:16 p.m. and extend to 3:15 p.m.

3:20 p.m. - The NASA launch manager has aborted the launch due to high winds at the pad. We are no-go at T-2 minute 34 seconds. We will recycle for a 24-hour turnaround.

3:19 p.m. - We are at T-4 minutes and counting. We will continue to monitor our wind speed limits.

3:14 p.m. - With 4 minutes and 40 seconds in the hold, the NASA launch manager has decided pick up the count. If the winds exceed our limits during that time, we will not launch. The wind limits at the pad are 33 knots and we have exceeded that several times today.

3:07 p.m. - We are just under the ground wind speed limits for launch. If we exceed those limits within the last 8 minutes of the countdown we will not be able to launch today.

Did You Know?
The New Horizons spacecraft will take at least 9 and a half years to reach Pluto and its moon, Charon. That means that a student who is now in first grade would be just finishing up with 10th grade!

2:57 p.m. - A new launch time has been targeted for 3:23 p.m. to study the ground winds for a safe launch today. There are 20 minutes remaining in this built-in hold.

2:52 p.m. - We are continuing to monitor the ground winds at this time. Atlas and Centaur are fueled and fully loaded. There continue to be no other technical issues and all ground assets are nominal.

2:43 p.m. - Because of continued windy conditions, a new launch time has been issued for 3:05 p.m. There are now 17 minutes remaining in the hold.

2:40 p.m. - Data from weather balloon 8 is being uploaded into the Atlas rocket.

Did You Know?
Pluto is a new type of planet. It is an ice dwarf which is common to the deep outer solar system.

2:30 p.m. - All ground assets are now ready to support the launch today. We are still working with the winds issue. Launch is currently scheduled for 2:50 p.m. and we remain in the T-4 minute hold.

2:27 p.m. - At this time the range is green. The Antigua tracking station is back online and available for launch.

2:23 p.m. - A new launch time has been established for 2:50 p.m. due to a computer problem with the Deep Space Network. The issue has been resolved.

2:15 p.m. - The latest weather data is being uploaded into the Atlas rocket. We are continuing to monitor the winds, working toward a launch of 2:30 p.m. this afternoon.

2:10 p.m. - Wind issues for the countdown are continuing to be assessed. At this time, we're still at T-4 and holding.

2:07 p.m. - A mandatory tracking station, located in Antigua in the eastern Carribbean, has gone off-line. This station must be operational for launch. There's an expectation that it will be available at 2:20 p.m.

Did You Know?
Pluto only orbits the Sun once every 248 Earth years, and is about 40 times farther out than Earth.

1:59 p.m. - Weather balloons 10 and 11 have been released to check the current wind speeds.

1:57 p.m. - Launch time has now been adjusted to 2:30 p.m. because of wind speed issues.

1:53 p.m. - We are awaiting data from the latest balloon release to determine the current upper-level and ground winds speeds. Ground wind speeds have been gusting at 33 knots. There are 12 minutes left in the built-in hold.

1:37 p.m. - The NASA Launch Manager and his team have adjusted the new launch time to 2:10 p.m. The launch window for today extends to 3:23 p.m.

1:35 p.m. - The NASA Launch Manager is a conducting poll on whether to release the hold. The NASA team is a "go" pending the results of incoming weather data.

1:34 p.m. - Based on the results of the weather balloons, a decision will be made to either extend or come out of the hold. There continue to be no technical issues at this time.

1:23 p.m. - The fill and drain value on the Atlas liquid oxygen tank is operating properly and should not be an issue for launch today. Weather is currently red due to upper level winds and ground winds continue to gust.

Did You Know?
The United States has been the first nation to reach every planet from Mercury to Neptune with a space probe.

1:14 p.m. - A new launch time is being set for 1:45 p.m. this afternoon due to issues with excessive southerly upper-level winds.

1:10 p.m. - At T-4 minutes and holding, we are now in the 10-minute, built-in hold.

1:06 p.m. - During the Atlas V weather briefing, the launch weather officer gave his report about the conditions for launch. He reported winds out the south may surpass launch constraints.

1:02 p.m. - We are now at 11 minutes and counting. At T-4 minutes we will go into a 10-minute, pre-programmed built-in hold.

Did You Know?
It took the Apollo missions more than 3 days to reach the Moon, but the New Horizons spacecraft aboard the Atlas V will only take 9 hours. This will be the fastest spacecraft ever launched.

12:44 p.m. - We are now at T-30 minutes and counting. At this time there are no technical issues at work.

12:40 p.m. - Centaur LO2 tank is now loaded at 100 percent flight level.

12:34 p.m. - At T-40 minutes, topping off of the Centaur hydrogen tank is occurring. Atlas LO2 is 97.5 percent full and is also in the process of being topped off.

12:29 p.m. - We are now at T-45 minutes and counting. Centaur hydrogen loading is at 90 percent.
