Early this morning United Launch Alliance successfully launched NASA’s Ice, Cloud, and Land Elevation Satelite 2 (ICESat2).
The launch was slightly delayed due to an issue with the bottle temperatures during the countdown. This issue was quickly resolved and the mission completed successfully.
This was the final launch of the venerable Delta II which has been launching since 1989 and completed 154 missions, 1 failure, and 1 partial failure. With this launch, Delta II also achieved an important milestone of 100 consecutive launch successes.
