Countdown Holding

This is Atlas Launch Control at T-minus 2 hours (L-3 hours) and holding. The countdown has entered the first of two planned, built-in holds that are scheduled in today’s timeline. This first block of time gives the countdown some margin to resolve issues or catch up work that could be running late, and the hold provides an opportunity to ensure all is ready before fueling operations begin.

The final hold occurs at T-minus 4 minutes.

At the present time, all activities are on schedule and no problems are being addressed by the launch team.

Weather Improves to 80% GO

In the pre-fueling weather briefing to mission management, Launch Weather Officer Jessica Williams reports that conditions continue to look favorable for launch today.

The launch time forecast has improved to an 80 percent of acceptable weather as dry air moves into the area. Ground winds and cumulus clouds are only minor concerns.

The outlook for launch time calls for some scattered low clouds, good visibility, northwesterly winds of 10 gusting to 15 knots and a temperature near 76 degrees F.
