Together with the French space agency CNES (Centre national d'études spatiales) and ArianeGroup, the German Aerospace Center (DLR) has expanded the European research and technology test bed P8. The partners opened the new test cell P8.3 in 2021. With the expansion of the facility, DLR has created the conditions for future space propulsion systems to be developed and tested almost entirely at the Lampoldshausen site. DLR in Lampoldshausen has unique expertise, infrastructure and many years of experience in this field. The interaction between research and development creates important synergies and strengthens engine expertise as an important pillar of European space transportation.
