We have shipped our 20kW satellite - Gravitas - to the launch site. Given the supply chain to operate at this power regime doesn’t exist, we had to build 85% of the satellite in-house. This includes building our own large solar arrays, high power propulsion system, large batteries, large reaction wheels and much more. This launch will represent the first time all of these systems are test on orbit together. Internally at @K2SpaceCo, we’ve thought about a few levels of success for this mission - we expect mission success to fall somewhere along this spectrum: - Tier 1 (Baseline mission success): Deploy solar arrays, establish comms, operate the satellite —> we’ve now got an operational 20kW satellite on orbit - Tier 2: Power on the payloads, activate the 20kW propulsion system —> we’re completing payload missions and have fired the highest power hall thruster ever flown on orbit - Tier 3: Orbit raise the satellite, test performance in high radiation environments (like 2,000km) —> we’ve collected massive amounts of data on the performance of the platform in very very difficult environments More than anything, Gravitas represents the start of an iterative journey, where we will take the data we receive from this first satellite and incorporate it into the next wave of satellites launching next year. We’re excited to start this journey, we’ll report back as we get more data. Thanks to Tim for covering our story on TechCrunch techcrunch.com/2026/03/19/k2…
