Problem
Current launch solutions lack cost-effectiveness and reusability, hindering the expansion of in-space services and human spaceflight programs. The high cost of single-use launch vehicles limits the accessibility and frequency of space missions.
Solution
EtherealX is developing the Razor Crest Mk-1, a fully reusable medium-lift launch vehicle designed to provide cost-effective and reliable access to space. Equipped with nine Stallion liquid rocket engines, the Razor Crest Mk-1 can deliver payloads to low Earth orbit (LEO), Geosynchronous Transfer Orbit (GTO), and Translunar Injection (TLI). The reusability of the vehicle significantly reduces launch costs, making space missions more economically viable.
Target Audience
The primary target audience includes satellite manufacturers, space agencies, and organizations involved in in-space services and human spaceflight programs.
