Stoke’s Nova rocket, designed to be
completely reusable.

The rocket startup Stoke Space announced earlier this week it has successfully completed all tank tests for 1st stage of its Nova rocket, thus increasing the odds that the rocket’s first launch will occur before the end of this year.

During this campaign, the team filled both tanks above their maximum expected pressure conditions, demonstrated automated pressure control across a range of fill levels, and operated the vehicle through challenging environmental conditions, including hurricane-force winds and a severe lightning storm. More than just a successful structural test campaign, the result was a broader demonstration that Nova’s hardware, software, ground systems, and operations approach are maturing together.

The company noted that it is not unusually for new rockets to experience explosions and other failures during this testing phase, thus making its complete success without a failure “a significant achievement.”

Stoke has consistently refused to set a launch date as it has been developing its rocket. It approach has been simply “We will launch when we are ready.” It has had this luxury in that it has successfully raised $1.34 billion in private investment capital, attracted to the company because of its rocket’s radical design that will allow both its first and second stages to be reusable. The first stage will land vertically, as does SpaceX’s Falcon 9.

The second stage uses a revolutionary nozzle design that makes its return possible. Instead of a single central nozzle, the engine has a ring of small nozzles on the outside edge of its heat shield. The stage will then return to Earth like a capsule, with those nozzles adding force to control and slow its descent.

The rocket itself has a smaller payload capacity than a Falcon 9, but its ability to be completely reusable means its second stage is far more capable. It can fly multiple times, thus lowering the launch costs for its customers. It can also provide an orbital manufacturing site, like a Varda capsule, which will attract a much larger customer base.
