Problem
Current multi-stage rocket systems involve complex designs and high operational costs due to the need for jettisoning stages and managing multiple engines. This complexity increases the risk of failure and limits the frequency and affordability of space launches.
Solution
Space Transit is developing a single-stage-to-orbit (SSTO) spacecraft designed to drastically reduce the cost and complexity of space access. Their approach centers on an air-breathing, liquid oxygen/liquid hydrogen rocket engine that collects and liquefies air during ascent, reducing the reliance on onboard liquid oxygen until the spacecraft exits the atmosphere. This technology enables a lighter vehicle structure and eliminates the need for stage separation, leading to lower development, manufacturing, and maintenance costs. The company aims to establish a high-frequency space transportation system for small satellite deployment and, eventually, crewed missions.
Target Audience
Space Transit's primary customers include small satellite operators, space tourism companies, and government agencies seeking affordable and frequent access to space.
