A launch grouping dozens of satellites from unrelated owners, concentrating independent insured interests on a single event.
A rideshare launch carries dozens of satellites belonging to unrelated operators on a single vehicle, each paying by the kilogram for a slot on a standardized mission profile it does not choose. The practice has cut the cost of reaching orbit by an order of magnitude for small satellites and has become the normal route to space for start-ups and laboratories. For insurance it inverts an implicit assumption of the class: where a launch historically carried a single interest of known value, a shared flight carries dozens of distinct interests, priced by different insurers, none of whom knows the total value exposed to the same event. A launcher failure then produces an accumulation invisible in any one portfolio, exactly the mechanism cyber underwriting learned to name elsewhere. A sequencing difficulty compounds it, since staged deployment means some passengers are separated and others are not when a late failure occurs, multiplying loss characterizations for one flight.
The SpaceX Transporter-1 flight, launched on 24 January 2021, placed 143 spacecraft belonging to dozens of different operators into orbit, then a record for satellites deployed by a single launch.
