The European Space Agency (ESA) has now committed 33 million euros for ArianeGroup to develop a prototype vertical landing hopper dubbed Themis that would begin testing first stage landings by ’23.
ArianeGroup and its collaborators in Belgium, Switzerland, France and Sweden offer critical technical knowhow gained through the development of Europe’s next-generation engine – Prometheus – which will power Themis.
ESA’s Prometheus is a highly versatile engine capable of providing 1000 kN of variable thrust and is reignitable which makes it suitable for core, booster and upper stage application. An onboard computer handles engine management and monitoring in real time – a crucial feature for reusability.
ArianeGroup is the private consortium led by Airbus and Safran that is building Ariane 6. This deal suggests that ESA amd ArianeGroup has finally recognized that Ariane 6, built without reusability, is a lemon and is not attracting customers. This new contract starts the process of developing a reusable first stage.
They still might be too late. They will only begin testing the Themis prototype in ’23, with no clarity on when a full scale version will follow. Meanwhile, it is very likely that SpaceX’s fully reusable Starship/Super Heavy will be flying orbital missions by then, and likely charging far less than they presently do for their Falcon 9.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space
, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
