SPACE: How to watch the launch of Europe’s JUICE mission to Jupiter on April 14: Europe’s Ariane 5 rocket will have only one second to lift off at 8:14 EDT on Friday, April 14. “Due to the intricacies of the trajectory that will take JUICE to the gas giant planet, the rocket has to lift off during a one-second window, but Arianespace representatives said in a pre-launch news conference that the team has built margins into the pre-launch procedure to absorb any delays and deviations. Fortunately, additional one-second launch windows will be available every day until the end of April.”

That’s an awfully narrow launch window.
