The Starship prototype SN9 is starting at the company's development facility in Boca Chica, Texas.
SpaceX closed another $ 850 million monster equity financing round last week, people familiar with the financing told CNBC, bringing the company's valuation to around $ 74 billion.
The company raised the new funds at $ 419.99 per share, these people said – or just a dime below the $ 420 price that Elon Musk infamous for in 2018 when he said he "secured the funding" to Tesla to take privately.
The latest increase also means company valuation is up about 60% from the August preliminary round when SpaceX raised nearly $ 2 billion on a valuation of $ 46 billion.
SpaceX did not immediately respond to CNBC's request for comment.

In addition to further building a war chest for SpaceX for its ambitious plans, insiders and existing investors were able to sell an additional $ 750 million in a secondary transaction, one respondent said.
In particular, SpaceX has only raised part of the funding available in the market. One person told CNBC that the company received "insane demand" of approximately $ 6 billion in offers in just three days.
Cash for Starlink and Starship

The recent inflow of funds is due to SpaceX developing two capital-intensive projects at the same time.
Starlink is his ambitious project to build an interconnected Internet network with thousands of satellites, known in the aerospace industry as a constellation, designed to deliver high-speed Internet to consumers around the world. SpaceX's leadership previously estimated that Starlink would cost at least $ 10 billion to build, but believe the network could bring in up to $ 30 billion a year – or more than ten times its annual revenue existing missile business.
SpaceX has launched more than 1,000 satellites for Starlink to date and has begun serving customers in the US, Canada and the UK in an early public beta. The company recently expanded the scope of this public beta to allow potential users to pre-order Starlink service for $ 99. Pre-order messages tell users that SpaceX is "targeting coverage in your region by mid-to-late 2021," while others are stating pre-orders in 2022.
The company announced in a release from the Federal Communications Commission last week that Starlink had "over 10,000 US and international users" in just over three months since public beta began.
Musk also reiterated last week that SpaceX plans to eventually outsource Starlink and bring it to the public. He said Starlink "needs to cross a deep negative cash flow gap over the next year or so."
"As soon as we can predict the cash flow reasonably well, Starlink will go public," said Musk.
SpaceX's starship rocket is another ambitious endeavor. The company is constantly building and testing prototypes in Boca Chica, Texas. The company has successfully launched several Starship prototypes and safely landed them after short flights at approximately 500 feet. Despite exceeding several development milestones, the two most recent high-altitude flights exploded on impact after attempted landings.
The Starship prototypes are made of stainless steel. The company's aim is to develop a missile system that is reusable, similar to a commercial aircraft. SpaceX is developing Starship with the aim of launching cargo and up to 100 people simultaneously on missions to the moon and Mars.
Despite the explosive end to the last two flights, SpaceX has viewed the launches as advancing the rocket's development. The next Starship prototype is on the company's launchpad. SpaceX is expected to attempt another test flight in the coming weeks.
