Sizing up the 5 companies selected for Europe’s launcher challenge

The managers of the European space cited the rule of geographic yielding as a reason for delays and cost exceeding on ESA projects, including Ariane 6, which made its debut in July 2024, several years late. Essentially, the policy forces ESA to choose entrepreneurs in countries that provide funding for each program, whether they offer a most reliable or profitable solution.

With the European Launcher Challenge, ESA upsets this policy by first selecting launch entrepreneurs, then going to their original governments to obtain funding for the program.

Two of the challengers selected by ESA come from Germany. Isar Aerospace, whose headquarters are in Munich, develops a small orbital launch vehicle in two stages named Spectrum. Just northwest of Munich, Rocket Factory Augsburg develops a rocket called RFA One with capabilities similar to the spectrum.

Maiaspace belongs to Arianegroup, the parent company of Arianespace, based in France. Spanish Company PLD Space is developing a launch vehicle called Miura 5 and in 2023 launched its first rocket supplied by liquid in the upper atmosphere on an under-director test flight. Orbex, whose siege is in the United Kingdom, works on a rocket called Prime. The five corporate rockets are currently preparing for their efforts to the small satellite launch market.

The European launcher challenge will include two components, the first of which will be for the launching services for ESA missions providing for the launch of 2026 to 2030. The second part will be a contract to demonstrate an upgrading of the launch service capacity, including at least one flight demonstration of the increased launch vehicle. The ceiling of 169 million euros per challenger will include all activities in both parts of the challenge.

“With this initiative, ESA takes decisive measures towards marketing and expansion of launch services, which are essential to ensure sovereignty in space,” wrote Isar Aerospace on X.
