He isn’t very optimistic.

Tesla and SpaceX founder Elon Musk recently admitted that his company is going to launch its Starship spaceship into orbit for the first time in January but warned people that it might not be successful.

According to Yahoo, Just before the launch, SpaceX is expected to carry out several tests Musk said in a recent video call.

Musk highlighted just risks when it comes to launching a spaceship for the first time. He told Americans who have high hopes for SpaceX to be reasonable with the expectations of success when it comes to a first time launch.

“There’s a lot of risk associated with this first launch, so I would not say that it is likely to be successful, but we’ll make a lot of progress,” he said.

Musk then said he is confident that the Starship will reach orbit at some point.

“I’m not sure we’ll get there on the first attempt, but I’m comfortable we’ll get there next year,” he added.
