Launch Moves to Sunday: Forecast 40 Percent ‘Go’

The launch of Orbital ATK’s Cygnus cargo spacecraft to the International Space Station has moved to Sunday at 4:44 p.m. EST, the start of a 30-minute launch window for the uncrewed spacecraft to begin it mission. Countdown and launch coverage will begin here on the NASA Blog and on NASA TV at 3:45 p.m.

Saturday’s attempt was called off because of high winds that were expected to violate launch criteria throughout the 30-minute launch window. The weather forecast for Sunday improved to a 40 percent chance of acceptable conditions at launch time.

  1. All space lovers will be watching here tomorrow. Here in Lisbon will be 9:44pm. Good luck. Godspeed.

  2. Thanks for the excellent coverage of our space program. I appreciate the updates on launch postponing events beyond not having to stand in my yard looking at the sky for an hour not to miss seeing the event. I feel like I am participating in history and learning about science while doing it. I believe in science and scientific research. I oppose those who want to keep our nation ignorant of the revealed facts from scientific research. I live vicariously through your activities. Thank you for improving the quality of humani experience.

  3. I was actually quite pleased to find the launch for Orbital ATK was delayed. Why? Because, regardless of how persistent the nagging thought of having forgotten something all day yesterday (the 5th of December 2015, and scheduled launch date) I could not recall just what it was. My first waking thought this morning was that I had missed the launch coverage. So, quite pleased to find that I’m getting another chance at that.
