SpaceX is standing down from attempting to launch its powerhouse Falcon Heavy for now citing the need for "systems checkouts" while weather would have been an issue the next couple of days, and has already delayed a Falcon 9 launch as well.

After already delaying a Sunday attempt to launch Falcon Heavy from Kennedy Space Center's Launch Pad 39-A because of weather and then scrubbing a Monday night attempt less than an hour before its planned liftoff because of a "ground side issue," SpaceX had announced it would try again Wednesday.

But late Tuesday, it called off those plans.

"We are standing down from tomorrow's Falcon Heavy launch of USSF-52 to perform additional system checkouts," the company posted to X. "The payload remains healthy while teams work toward the next best launch opportunity. We're also keeping an eye on the weather and will announce a new launch date once confirmed with the Range."

USSF-52 is a mission to send up the Space Force's secretive mini shuttle, the X-37B Orbital Test Vehicle built by Boeing, on what would be the spacecraft's seventh trip to orbit.
