# Aspire Space and LEAP 71 partner to build reusable space launch systems

[Aspire Space](https://www.voxelmatters.directory/company/aspire-space/) and [LEAP 71](https://www.voxelmatters.directory/company/leap71/) have announced a strategic collaboration to develop a new, large reusable launch vehicle capable of delivering up to 15 metric tons to low Earth orbit (LEO). Founded in Luxembourg and led by veterans of launch programs like Zenit, Soyuz, and Sea Launch, Aspire Space is relocating its core operations to the United Arab Emirates. This move supports the UAE's ambitions to lead in the growing global space economy.

It uses its proprietary Large Computational Engineering Model, Noyron, to design next-generation aerospace hardware. Under the partnership, LEAP 71 will develop the entire propulsion system for Aspire’s rockets. The first-stage engines will be based on the company’s XRB-2E6 design—a high-performance, reusable Methalox (liquid methane/liquid oxygen) engine delivering 2,000 kilonewtons of thrust, comparable to top U.S. launch systems.

Stan Rudenko, CEO of Aspire Space, stated: "Sovereign space access and rapid reusability are essential for global space leadership. LEAP 71’s presence in the UAE gives us a local, strategic advantage. Relocating our team here was a clear choice as we aim to support the Emirates’ bold space ambitions."

"We created LEAP 71 to speed up engineering itself using advanced computational tools," added Josefine Lissner, CEO of LEAP 71. "Our collaboration with Aspire unlocks decades of industry knowledge and puts it into action."

LEAP 71’s Noyron platform integrates engineering logic, physics, manufacturing constraints, and feedback into a deterministic system that autonomously generates manufacturable hardware. Unlike probabilistic AI, Noyron is based on first principles of science and engineering.

Lin Kayser, Co-Founder of LEAP 71, further commented, "True innovation depends on iteration, and traditional design processes are slow. Noyron allows us to convert expert knowledge into code, dramatically reducing development time—from months to days. Future space systems will be computed, not drawn."

In the past year, LEAP 71 has successfully designed and hot-fired a new rocket engine every 30 days, including a working aerospike engine—one of the most complex propulsion systems ever built.

Sergey Sopov, CTO of Aspire, shared: "We've built rockets the traditional way for decades—reliable but slow. LEAP 71’s technology lets us transform our experience into fast, repeatable innovation. This marks a new era in aerospace."

In addition to the launch vehicle, Aspire is also developing a reusable spacecraft capable of carrying up to 2 metric tons to and from orbital stations. Hot-fire testing of the propulsion system begins in Q3 2026, starting with the 200 kN second-stage engine. The first launch of the new system is planned for 2030.
