Impulse Space added $308 million to its recent Series D round. The company said Wednesday it extended that $500 million round, announced in June, with several existing investors participating. The additional money will help Impulse Space scale its team and work on new product development. The company has flown three of its Mira maneuverable spacecraft, two of which recently completed proximity operations that saw them come within 200 meters of each other. A fourth Mira is scheduled to launch next month, while the company works on its larger Helios kick stage for a 2027 first flight.
