SpaceX scrubbed a Falcon 9 launch attempt Thursday, citing an issue associated with the planned recovery of the rocket’s first stage or payload fairing in the Atlantic Ocean. Officials later said the mission would be grounded to await improved weather in downrange recovery area in the Atlantic Ocean.

Crews working on Virginia’s Eastern Shore this week raised a top secret payload for the National Reconnaissance Office — the U.S. government’s spy satellite agency — atop a solid-fueled Minotaur 4 rocket for liftoff July 15 on the first Minotaur launch in nearly three years.

In keeping with the agency’s strict medical privacy policy, NASA officials have not identified the astronaut in question or provided any details about the nature of the medical issue.
