K2 Space is poised to launch its inaugural high-powered satellite, Gravitas, aboard a SpaceX Falcon 9 rocket by the end of March 2026.
Weighing two metric tons with a 40-meter wingspan when solar panels deploy, Gravitas generates an impressive 20 kW of electricity to power advanced payloads for space compute applications.
From SpaceX Roots to Satellite Innovators
Founded in 2022 by brothers Karan Kunjur and Neel Kunjur, both former SpaceX engineers, K2 Space has rapidly scaled with $425 million in funding and a $3 billion valuation as of December 2025.
The company's focus on high-power satellites stems from the growing demand for robust orbital processing and communications in an era dominated by mega-constellations.
Gravitas Mission: Payloads and Powerhouse Thruster
Gravitas carries 12 undisclosed payload modules from various customers, including the Department of Defense.
At its core is a groundbreaking 20 kW electric thruster, the most powerful ever flown in space, enabling significant orbit maneuvers.
Success will be measured in tiers: initial deployment and power generation, followed by payload operations and thruster tests, culminating in thousands of kilometers of orbit raising.
Revolutionizing Space Compute and Communications
This launch addresses critical needs for higher throughput, jamming-resistant signals, and on-orbit data processing with advanced processors.
Historically, most satellites produce only a few kilowatts, but leaders like Starlink's V2 mini approach 28 kW, setting the stage for K2 Space's advancements.
Looking ahead, K2 Space plans to deploy eleven more satellites within two years, transitioning to commercial networks by 2028.
Designs for 100 kW satellites are ready, positioning the company for cheaper launches on vehicles like Starship and New Glenn.
CEO Karan Kunjur emphasizes that higher power unlocks new economic opportunities as satellites integrate deeper into global infrastructure.
