Space exploration is evolving rapidly, with satellites and spacecraft playing a critical role in communication, navigation, and scientific research. However, traditional propulsion systems rely on toxic and inefficient fuels, mostly a mixture of hydrogen and oxygen, creating both environmental and operational challenges. Enter Dream Aerospace, a Chennai-based startup that is redefining space propulsion with its innovative, non-toxic, and high-performance thruster technology.

The Genesis
Founded in 2022 by Hari Krishnan KJ and Rogith S, Dream Aerospace was born from the realisation that conventional satellite propulsion systems are outdated, hazardous and, more importantly, inefficient. With the increasing number of satellites being deployed, there was a pressing need for efficient, eco-friendly propulsion solutions. The duo, along with their team, set out to bridge this gap by developing green and high-performance thrusters that would not only be safer but also enhance the efficiency of space missions.
Their journey was far from easy. The aerospace industry is heavily regulated and dominated by established players, making it challenging for new entrants to gain traction. However, Dream Aerospace’s breakthrough innovation, the ATOM Green Monopropellant Thruster, set them apart from the competition and placed them on the radar of investors and industry leaders.
Revolutionising Space Propulsion with ATOM Thruster
Dream Aerospace’s flagship product, the ATOM Thruster, is a game-changer in space propulsion. Unlike conventional hydrazine-based thrusters, which use highly toxic and carcinogenic propellants, ATOM operates on a Hydroxylammonium Nitrate (HAN)-based green monopropellant, significantly reducing toxicity and handling risks. This innovation aligns with the global shift toward sustainable space exploration while enhancing efficiency and safety for satellite missions.
The ATOM Thruster is designed to be compact, reliable, and efficient, making it ideal for small satellites, a segment experiencing exponential growth. The company’s propulsion system provides 30% higher performance than traditional hydrazine-based alternatives, improving satellite longevity and manoeuvrability.
Dream Aerospace has also pioneered an in-house high-altitude test facility, allowing for rigorous testing and validation of its propulsion systems under real-space conditions. This ensures the thrusters meet the highest industry standards before deployment.
Scaling Impact Across the Space Industry
Since its inception, Dream Aerospace has gained significant traction. The company has collaborated with premier research institutions and space agencies to test and refine its technology. Their propulsion systems have attracted interest from both commercial satellite manufacturers and defence organisations looking for safer and more efficient alternatives.
In January 2025, Dream Aerospace secured ₹3 crore ($360,000) in pre-seed funding led by Inflection Point Ventures (IPV). This funding is being used to accelerate product development, expand their R&D capabilities, and further validate their thruster technology. The company is also in discussions with global aerospace firms for potential partnerships and pilot projects.
Addressing the Sustainability Gap
Space debris and hazardous propellant waste are growing concerns in the aerospace sector. According to the European Space Agency (ESA), over 36,500 pieces of debris larger than 10 cm are currently orbiting Earth, posing a severe risk to active satellites and future missions. A significant contributor to this issue is the inefficient disposal of outdated propulsion systems and toxic fuel residues.
By developing a non-toxic, environmentally friendly propulsion solution, Dream Aerospace is directly addressing this challenge. The ATOM Thruster eliminates the need for hazardous propellants, making satellite decommissioning safer and reducing long-term space pollution. Their green fuel also ensures safer handling, minimising risks for ground personnel and engineers.
A Model for Impact-Driven Growth
Dream Aerospace’s journey exemplifies the power of innovation in a highly technical and competitive industry. The startup has carved out a niche in the growing small-satellite propulsion market by focusing on safety, sustainability, and performance.
Dream Aerospace represents a new era of responsible and efficient propulsion technology for industry leaders and space mission planners. “Our mission is to make space safer and more sustainable,” says Hari Krishnan KJ, Co-founder and CEO. “With our ATOM Thruster, we are enabling the next generation of satellite missions while prioritising environmental responsibility.”
As satellite deployments continue to rise, the demand for reliable, sustainable, and high-performance propulsion systems will only increase. With its pioneering technology and unwavering commitment to innovation, Dream Aerospace is poised to lead this transformation, one thruster at a time.
