ICESat-2 Weather Remains Favorable for Launch

Weather remains favorable for the Sept. 15 launch of NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) from Vandenberg Air Force Base in California on a United Launch Alliance Delta II rocket. The latest forecast from the U.S. Air Force 30th Space Wing predicts a 100 percent chance of favorable weather on launch day with patchy fog and visibility of 2-3 miles.

The spacecraft window opens at 5:46 a.m. PDT (8:46 a.m. EDT) and extends for 2 hours, 34 minutes.

The launch vehicle window is now approximately 50 minutes based on the launch team’s decision to load RP-1 fuel during the countdown, approximately 2 hours and 40 minutes prior to the beginning of the launch window.
