Since years Novespace and Astrium are discussing mutual interest in cooperating together when considering Novespace well established capabilities and the ongoing development of the Astrium Spaceplane and its unique features. Indeed both companies are proposing service for non-public missions which require microgravity environment especially. It relies on assets of both parties: •Novespace in operating 0-G aircraft platforms for the sake of the European scientific community for decades;•Astrium and its Spaceplane currently in pre-development phase. Novespace and its Airbus A300 Zero-G exhibit a unique know-how in Europe for operating scientific payload on aeronautic platform(s). Moreover Astrium is preparing the development of a safe and passenger friendly Spaceplane, taking off and landing from a standard airport runway powered by turbofans and using a rocket engine of proven design to reach 100km altitude. The paper details the joint service offered and the added value of the partnership of Novespace and Astrium for various end-users. In addition longer duration of on-board microgravity periods and ultra high altitude features of the Astrium Spaceplane mission expand the scope of possible non-public applications which includes e.g.: •Earth system science and probing of uncharted layers of Earth atmosphere on a regular basis and in various locations worldwide;•Spaceflight crew training. ► Astrium and Novespace joint offer for scientific community. ► Applications including 0-G, ultra high altitude and spaceflight crew training oriented missions. ► Aeronautic-like certification for operations of Astrium Spaceplane from existing airport(s). ► One stop-shop and cost-effective service.
