At the end of July, the Bavarian company Rocket Factory Augsburg (RFA) managed to fire the engine of its RFA One rocket for the first time, in eight seconds, at the Kiruna test site in Sweden.

Another young company in the sector, HyImpulse, based in Baden-Württemberg, also tested its prototype rocket engine for more than 20 seconds, in May, in the Shetland Islands, Scotland, using a gasoline based on… candle wax, should be to burn very quickly for a good performance.
Our technology is advanced enough to serve the small launcher marketsaid HyImpulse co-founder Christian Schmierer, 33.
A third actor, Isar Aerospace, near Munich, is still waiting to conduct the first test on the machine.
However, it was the best funded of the three, with a bouquet of investors including fund HV Capital, Swiss bank Lombard Odier and the Porsche SE holding company. Among others, they brought in more than 150 million euros to this start -up company run by engineers in their early thirties. Its first Spectrum rocket flight is expected in 2022.
A $ 45 billion market
These projects make Germany one of the most serious competitors in the competition opened by the announced market departure for satellites to observe the Earth and cover the Internet needs of machines or connected cars.
The market must be reached

The large rocket is the main bus line that drops off its passengers at the same stop, while a micro-launcher will work like a taxi, placing satellites at the exact location the customer wants.explains Christian Schmierer, owner of HyImpulse.
These satellites of several hundred kilograms are like hand luggage compared to the loads of more than 10 tons sent into space by the Ariane rocket, the spear of European space.
The smallest of them will be

The future of car manufacturers
The three German companies are relying on a fleet of 20 to 40 partially reusable rockets, which will ensure dozens of take-offs each year.
Automotive subcontractors, looking for outlets as the years of production of internal combustion engines are counted, will be able to join the sector by providing rocket engine parts.
We wanted to create a Henry Ford moment for space travelassured Jörn Spurmann, in reference to the American industrialist who changed the methods of vehicle production.
But Germany is far from alone in the range of this profitable market. In addition to SpaceX, which is already putting mini-satellites into orbit and collaborating with NASA, the American company Rocket Lab is one of the pioneers and has already performed its first commercial flights.
China is also active, and Europe has half a dozen credible projects, particularly in Spain and the United Kingdom.
