K2 Space, a satellite manufacturing startup founded in 2022 by former SpaceX engineers Karan and Neel Kunjur, is preparing to launch its high-powered satellite, Gravitas, aboard a SpaceX Falcon 9 rocket. Scheduled for a launch as early as this month, Gravitas weighs two metric tons and features a 40-metre wingspan when its solar panels are fully extended.
Boasting a power output of 20 kW, Gravitas is designed to support intensive payloads, such as advanced sensors and computing systems. To put this in context, traditional spacecraft typically only generate a few kilowatts of electricity. The CEO, Karan Kunjur, highlights the importance of high power for the industry’s future, emphasising that K2 Space has successfully secured $450 million in funding and is valued at $3 billion as of late 2025. This launch will mark K2’s initial foray into operational space missions, which Kunjur refers to as a pivotal moment in their developmental journey.
The Gravitas mission includes flying 12 undisclosed payloads for various clients, including the Department of Defense, alongside a 20 kW electric thruster—the most potent thruster ever deployed in space. Kunjur delineates success parameters for the mission: deploying Gravitas, generating power, running the payloads, and testing the thruster. If all goes well, they aim to elevate the spacecraft into a higher orbit.
With 85% of the satellite’s components engineered in-house, Kunjur is acutely aware of the challenges associated with launching new spacecraft. He insists the foremost focus will be on gathering data to inform subsequent designs, as K2 intends to launch an additional 11 satellites over the next two years, combining demonstration and commercial opportunities. By 2028, they plan to manufacture satellites for clients establishing commercial networks.
As the demand for orbit-based data processing surges, Kunjur anticipates a significant impact on communication networks, propelled by the enhanced throughput and resilience against interference that higher-powered satellites offer. However, launching large satellites remains expensive. K2’s foundational strategy revolves around utilising SpaceX’s Starship, which promises lower launch costs, although the timeline for its operational readiness remains uncertain.
K2 believes that their spacecraft can offer competitive solutions at an estimated launch cost of $7.2 million per satellite—significantly lower than the traditional $15 million price while delivering superior power than similarly priced smaller satellites. Kunjur expresses confidence in preparing for future advancements, with designs for a 100 kW satellite already drafted in anticipation of more powerful rockets coming online.
Overall, K2 Space aims to become a frontrunner in high-powered satellite manufacturing, strategically positioning itself for future demand in a burgeoning orbital economy.
