Elon Musk says SpaceX (NASDAQ:SPCX) is closing in on the milestone that would transform its economics: catching Starship’s upper stage and flying it again.

Traders who have watched his deadlines slip for years are not so sure.

“Looks like we will probably catch the ship with the tower in a few months,” Musk wrote on X on Wednesday. The first reflight, he added, would come “either end of this year or early next.”

A successful catch and reflight would demonstrate the ship can be reused, moving SpaceX toward the fully reusable rocket Musk says could cut the cost of reaching orbit a hundredfold. “That will be a fork in the road of history for consciousness reaching the stars,” he wrote.
