SpaceX chief Elon Musk appears to be tempering his enthusiasm ahead of the firm's third test flight of the fully stacked Starship rocket that is slated to take place early morning local time in Texas tomorrow. Starship is the world's biggest rocket in size and payload capacity, and SpaceX's tests aim to certify the rocket for operational status. So far, SpaceX has launched the second stage Starship several times as part of an earlier test campaign that sought to validate its design for a propulsive landing.

The fully stacked Starship, made of the second stage stacked on the Super Heavy booster, has been tested twice so far, with the tests marking incremental progress. Musk's comments, made on X, built on his earlier statement that had promised a launch tomorrow if the weather did not prove to be a constraint.

Elon Musk Maintains Cautious Tone Ahead Of SpaceX's Third Starship Test Flight

Throughout SpaceX's latest Starship test campaign, its chief executive and chief engineer Elon Musk has kept a low probability of success for the rocket to be a complete success at launch. Before the first test last year, Musk stressed that it was more likely than not for Starship to fail, and before SpaceX kicked off the current campaign, he had shared multiple times that production constraints related to its engine could end up delaying progress if SpaceX was careless.

While the constraints appeared to have resolved as SpaceX has increased its rate of Raptor rocket engine production, Musk still appears to be measured ahead of tomorrow's test. His latest Starship tweet (or X post) saw the executive remain doubtful that the rocket will take off tomorrow.

This is despite the fact that the FAA granted SpaceX approval to launch Starship tomorrow,
