Bangalore’s EtherealX Unveils Razor Crest MK-1 — The World’s First Fully Reusable Medium-Lift Rocket

In a groundbreaking leap for India’s space ambitions, Bangalore-based start-up EtherealX has introduced the Razor Crest MK-1, the world’s first fully reusable medium-lift launch vehicle. This next-generation rocket is poised to set a new benchmark in space transportation, combining raw power with unmatched efficiency and reusability.

At the heart of the Razor Crest MK-1 lies a powerhouse—nine Stallion engines, each generating 925 kilonewtons (kN) of thrust. Altogether, these engines deliver a total thrust that rivals some of the most advanced rockets in existence today. Designed using RP-1 and liquid oxygen (LOX) in a closed gas generator cycle, the Stallion engines are built for high-performance across both atmospheric and vacuum conditions. This design not only enhances mission flexibility but also makes reusability more feasible and cost-effective.

In terms of payload capacity, the Razor Crest MK-1 is nothing short of impressive. It can launch up to 24.8 tons to Low Earth Orbit (LEO) in an expendable configuration, 22.8 tons in a partially reusable mode, and 8 tons in its fully reusable form. Beyond that, it can deliver 10.8 tons to Geostationary Transfer Orbit (GTO) and 6.8 tons to Lunar Orbit—figures that place it firmly among elite global launch vehicles.

But what truly sets Razor Crest MK-1 apart is its full reusability. While many rockets can be partially recovered, EtherealX has engineered the MK-1 to return and relaunch its core stages, much like SpaceX’s Falcon 9 but tailored to meet the unique demands of both Indian and global markets. This innovation is expected to cut launch costs by up to 45%, opening up affordable access to space for commercial satellite operators, academic institutions, and governments alike.

EtherealX was founded in 2022 by a dynamic trio—Manu J Nair (CEO), Shubhayu Sardar (COO), and Prashant Sharma (CTO). With strong technical backgrounds and a shared vision of transforming India into a global space leader, they’ve quickly drawn the attention of investors and space enthusiasts worldwide. The company has already secured $5 million in seed funding to accelerate development and testing of its core technologies.

Their focus now lies on completing full-scale testing facilities, qualifying their engines for operational use, and preparing the MK-1 for its debut flights. The rocket is also being eyed for future human spaceflight missions, satellite deployments, and in-space services, making it a versatile platform with long-term utility.

The Razor Crest MK-1 not only showcases India’s growing technological prowess but also signals a shift toward more sustainable, cost-efficient space travel. As countries and companies race to dominate the new space economy, EtherealX’s innovation could play a pivotal role in democratizing space access for all.

With its bold vision, strong leadership, and revolutionary technology, EtherealX is no longer just a start-up to watch—it’s a trailblazer rewriting the future of space exploration.
