A NASA rocket launch off the East Coast was scrapped three times. Here’s why Amanda Kaufman Maybe the fourth time’s a charm? NASA was initially set to launch a rocket from its Wallops Flight Facility in Virginia on Saturday night, potentially offering East Coast residents a brief light show if weather permitted. But the launch was canceled. The agency rescheduled the launch for Sunday night, but again called it off and postponed it for the next night. Then the same thing happened on Monday. So, what’s the deal? Each time the launch has been canceled, NASA has cited weather conditions, saying on Twitter that “the launch has been postponed due to upper level winds not being within the required limits for a safe launch.”
