The era of stationary ballistic capsule may soon be over .
Portal Space Systems , a company headed by actuation expert Jeff Thornburg , is look to help usher in a new renaissance in in - space fare with its radical - mobile Supernova orbiter jalopy . believe of it as manoeuvrability - as - a - Robert William Service — tech that could propel transfers from downhearted Earth orbit to geostationary orbit in a affair of hours .
The 500 - kg Supernova is designed to be payload agnostical and survive on orbital cavity for at least five geezerhood while being incessantly maneuvered , the company said . It ’s a far rallying cry from legacy ballistic capsule , which are build to carry only as much propulsion as will be call for to maintain their orbit . Portal ’s designed a novel actuation arrangement , called solar - thermal actuation , that will produce a massive delta - V of 6 kilometers per instant , to enable rapid transfer to cislunar outer space , or as manoeuvrable assets to digest national security missions .
Portal was founded by place industry veterans Jeff Thornburg , COO Ian Vorbach and VP of engineer Prashaanth Ravindran . Thornburg ’s career reads like a history of the space industry writ large . Spanning nearly 30 age , it admit stints at basically ever major aerospace constitution : as a military officer in the Air Force ; process on liquid rocket engine engine tech at Aerojet ; five years at SpaceX , where he eventually became the 2d VP of propulsion technology ; working with storied entrepreneur Paul Allen at Stratolaunch ; and as a director at Amazon ’s Project Kuiper .
“ Then I decided I did n’t really require the big company life style and really wanted to dig in on some problems that were not being addressed by any other business , and so my co - founder and I founded Portal Space Systems in November of 2021 , ” he said . “ It ’s the only time I feel like I ’ve been able to prognosticate the future , even close . ”
give that he has spend most of his calling in launch vehicle evolution and actuation , he started think about what would come next in the industry after SpaceX cracked the computer code on affordable , speedy , reliable launching . He notice other trends , too : With more spacecraft launch to orbit than ever before , on - electron orbit collisions become more probable . On the defence side , Thornburg also started meet more of a national security interest in responsive distance capability and the ability for artificial satellite to manoeuvre “ without regret . ”
But satellites are n’t contrive for moving around a lot in orbit ; in world-wide , they are launched with enough on - control panel actuation to keep them in their intended orbit , not to put off other objects , and certainly not with out delta - V capability to go to high orbit . Supernova is part of a unexampled generation of spacecraft that are looking to change that .

The companionship has developed Supernova ’s propulsion system in - house . The solar - thermal system leverages legacy technical school designed by NASA and the Department of Defense , while innovating specific subsystem to optimise for military mission performance . For instance , the society is bringing a proprietary heating exchanger to that solar thermal propulsion system to give birth even high performance over a longer lifespan .
“ I think the big forcing function here for commercial-grade is just the proliferation of these LEO constellations that they have to maneuver around , and the forcing function for the DOD is China and the succeeding troth that people believe we ’re going to have with them over Taiwan and other progeny . Both of those things have come together at the same sentence , which has created the chance that I was hop for , but did n’t quite augur it being this significant . ”
Portal has raised an undisclosed amount of venture financing from unnamed backer , and the first Supernova development is fully fund , the company said . The squad has also gain ground over $ 3 million across five awards from the Space Force and the DOD , including a direct - to - form II SBIR that ’s focused specifically on developing antiphonal space operation .
Portal is target to conduct an in - flight of steps manifestation in tardy 2025 or early 2026 . But before that missionary station even launches , Thornburg enunciate the inauguration is looking to scale its team — which stands at around 25 masses , but anticipates will swell to up to 200 in 25 years — and grow manufacturing to underpin the production of multiple space vehicle per year after that first demonstration .
