Kepler's hosted-payload datasheet lists up to 120 kg payload mass, orbit-average power of at least 400 W subject to local time of ascending node, and 8 TB storage. Mission feasibility still depends on power, thermal, pointing and orbit requirements. The hosted-payload sheet lists 2.2 Gbps optical data relay and latency below 750 ms. These are vendor service specifications for the described configuration, not universal mission guarantees. The published sales route is sales@kepler.space.

Maverick secured capacity for ten 400 kg-class Kepler Tranche-2 satellites on Portal's Motus Via Sol mission, targeting a Falcon 9 launch in mid-2028. This is reserved future launch capacity, not a completed deployment. Kepler says Tranche 2 will extend its optical network with up to 100 Gbps data rates, on-orbit computing and integrated hosted payloads, supporting government and commercial missions including announced NorthStar and ESA programs.
