Billionaire entrepreneur Elon Musk warned on Tuesday that one of his companies would need to step up its efforts to avoid bankruptcy. Musk said on Twitter that SpaceX might need to launch more of its rockets into space to keep up with the costs and to stay in business.

Musk said that while bankruptcy in the short term is "unlikely," it is not impossible. He said the severe global recession is threatening to dry up the company's capital liquidity at a time when it is losing billions in developing its Starlink and Starship businesses.

The tweet comes after reports emerged that Musk had told employees over the long Thanksgiving holiday that he needed "all hands on deck." Reports citing the leaked email said that it had mentioned a "production crisis" within the company involving the manufacturing of Raptor engines for its massive Starship spacecraft.

SpaceX is currently planning to launch the next-generation spacecraft into space for the first time next year. The spacecraft is the centerpiece of the company and Musk's goals of sending millions of people to the moon, Mars, and beyond.

The company's Starship rocket is also vital in the success of its Starlink network. SpaceX plans to use the rockets to launch its second version of Starlink satellites into orbit, which it expects would provide a vital revenue stream for the company in the short and long term.

The leaked email reportedly said that the company is having problems producing enough reliable Raptor engines for the Starship rocket. The email said that if they can't get enough engines, they won't have the rockets to fly Starlink Satellite V2 into space.

At the end of the leaked email, Musk warned that SpaceX could face a "genuine risk of bankruptcy" if the situation did not change. He said that the company needs to launch at least one Starship rocket into space every two weeks by 2022.

While Musk hasn't responded to questions about the leaked email, he did say in a comment on social media that the problem with the Raptor engine production is currently "getting fixed."

Musk appears to be increasing the stakes in this situation when compared to his previous targets. He claimed on a live stream less than two weeks ago that he hoped for "up to a dozen" test flights of Starship in 2022 before flying "serious payloads" in 2023.

It wouldn't be the first time the company found itself on the verge of bankruptcy. Before SpaceX's first successful flight of a Falcon 1 rocket, Musk famously faced financial disaster.
