📝 EPISODE DESCRIPTION

K2 Space launched Gravitas — a 20kW satellite that is one of the highest-power spacecraft ever built. This is the story of the contrarian bet behind it. When the entire satellite industry was racing toward smaller satellites, brothers and co-founders Karan and Neel Kunjur bet on the opposite: build bigger. Because in space, everything comes down to power, and power scales with size. Four years later, that bet became real. Gravitas launched — full size, full capability, built almost entirely in-house by a team that stayed intentionally small the entire way. This film shows their journey: the bet the Kunjur brothers made, the team who believed in it, the years of engineering problems nobody had solved and the night everyone gathered to watch it go into orbit. [00:43] The meaning behind “K2” [02:08] The contrarian bet Karan and Neel made [04:40] The people who believed in K2’s thesis [06:25] Building Gravitas and preparing for the mission [08:31] Gravitas launches into orbit — K2 Space is building the infrastructure for humanity's next era in space — from national security and commercial satellites today to deep space exploration in the years ahead.
