Building high powered satellites for a mass abundant future

With a 20.6kW burn, we just shattered the record for highest Hall thruster burn ever completed on orbit – four times more powerful than any thruster that has ever flown in space. And that’s just the beginning. We’re continuing to test and refine our in-house, custom-designed avionics and propulsion systems for next year’s launches. Below, our gimbal moves our thruster while it fires in our vacuum chamber. Of course, we couldn’t resist the opportunity to draw our Dyson sphere logo, which represents the abundant space future that we’re aiming for as we push the bounds of what’s possible in space.

Karan Kunjur, co-founder and CEO of @K2SpaceCo, says laser-linked satellites could provide another route for high-volume data if terrestrial cables are disrupted. Hundreds of satellites with optical links between them could move data at terabit speeds, with enough redundancy built in to handle outages gracefully. Disclaimer: bit.ly/3H4dQj0

It was an honor to keynote the @Hillermuseum's 22nd annual gala last weekend. As someone who's been obsessed with space from an early age (that's the "Earthrise" on the wall of my childhood room), Hiller's mission to support STEM education for future generations resonates with me on a personal level. @neelkunjur and I took the love of space that educators nurtured and turned it into co-founding @K2SpaceCo. Thank you to the team at Hiller for doing all they do to cultivate the next generation of U.S. space leadership.

When our co-founders @KaranKunjur and @neelkunjur started K2 Space in 2022, they identified supply chain stability as a core aim in manufacturing large, high-power satellites both quickly and cost-efficiently. Four years later, we’re building close to 90 percent of our components in-house at our Torrance, California factory as we ramp up production to build up to 100 satellites per year. Connor Love (@ConnorLoveCA) and Collen Larson of @a16z name K2 Space alongside other American companies leading the reindustrialization effort and lay out the case for investing in all levels of the industrial base as we strive towards mass abundance on both earth and in space: a16z.com/the-case-for-the-am…

A 20-kilowatt satellite is flying today, and a 100-kilowatt platform is planned next. @neelkunjur, co-founder of K2 Space, on why progress in space compounds when improvements in launch enable improvements in spacecraft, and why K2 builds for mass production rather than one-off engineering.

"We need to own those things." Neel Kunjur, co-founder of @K2SpaceCo, on the lesson legacy satellite makers learned the hard way: outsource your components and you eventually outsource your schedule and cost. K2 builds its own.

At K2 Space, we made a contrarian bet that large, high-power satellites would be the foundational infrastructure for the new space economy. Four years and over $1B in signed contracts later, that thesis is being proven out as our high-power, high payload mass satellites allow our customers to achieve more in space at a fraction of the cost of traditional, smaller buses. Daniel Biedermann, Partner at @newspacecapital, highlights this trend in a recent piece below: "As a result of this kind of innovation, customers can fly much larger radars, communication systems, processors, and defence payloads without having to design a whole spacecraft from scratch. A small number of powerful mega-satellites could replace hundreds of smaller, weaker ones, cutting the costs of manufacturing, launch, control, and network." Read more: payloadspace.com/op-ed-the-t…

"Go smaller to go cheaper, faster." That was the message from a senior government official until @neelkunjur and @KaranKunjur, co-founders of @K2SpaceCo, asked which part he actually cared about. The answer was that one is impossible without the other. K2 treated it instead as an engineering problem, one the right group of engineers could solve. Disclaimer: bit.ly/3H4dQj0

I'm excited to share this detailed update on our Gravitas mission -- from design, to mission timeline, to what's next as we continue to successfully operate our first large, high power satellite on orbit and prepare for more launches in 2027 and beyond.

Gravitas Mission Update: Engineering Lessons from K2 Space's First Large, High Power Satellite

Now that our first 20kW Mega-class satellite Gravitas has been operating successfully in space for over 125 days, I thought it would be a good time to share some of K2 Space’s successes and learnings

Within hours of launch, @K2SpaceCo's Gravitas had separated from the launch vehicle, deployed its solar arrays, and established two-way communication with the ground. For co-founders @neelkunjur and @KaranKunjur, it was the first proof that customers could rely on what they had built. Gravitas then fired a Hall thruster four times more powerful than any previously launched and activated all 12 customer payloads in half the time budgeted. Disclaimer: bit.ly/3H4dQj0

“What makes California unique is not only the engineering talent, but also the technician talent. The greater LA area has a deep pool of talented technicians who are foundational to building any major aerospace company," our Co-Founder and CEO @KaranKunjur recently shared with SpaceNews: spacenews.com/satellite-manu… Fresh off a $500M Series D at a $6.8B valuation with over $1B in signed contracts, K2 Space is looking for technicians and engineers passionate about joining our contrarian bet to build bigger for an abundant future in space.
