Kepler Communications will buy its own rocket for the first time, booking a dedicated Rocket Lab Neutron medium-lift class vehicle for a 2028 mission to expand its optical data network, the company announced Monday.
The agreement marks a shift for Kepler, which has launches all of its 33 satellites to date by buying space on shared flights. The move to a dedicated launch gives the company control over exactly when and where its next-generation relay satellites reach orbit, rather than compromising to fit a primary customer’s schedule.
The timing aligns with a broader squeeze on affordable space access. SpaceX, which has dominated the commercial small-satellite market, has reportedly stopped accepting new commercial bookings for its Transporter rideshare missions beyond late 2028. That freeze is forcing operators who rely on those flights to secure alternative capacity before the window closes.
“Selecting Rocket Lab for our first dedicated launch marks an important milestone for Kepler as we continue to scale our infrastructure,” Mina Mitry, Kepler’s chief executive, said in the release. “Our customer demand continues to grow, and dedicated launch provides the flexibility to expand and deliver more capacity and capability to the missions we support.”
The cost of a whole rocket
Neither Kepler nor Rocket Lab disclosed the value of the launch contract or the number of satellites scheduled to fly. SpaceQ could not independently confirm the price, and Rocket Lab has not published a standard commercial rate for Neutron, which is still in development.
However, the financial commitment is substantially larger than Kepler’s prior deployments. On Jan. 11, 2026, the company launched 10 of its 300-kilogram Aether satellites on a SpaceX rideshare flight. Under SpaceX’s 2026 pricing of an estimated cost of US$7,000 per kilogram, that 3,000-kilogram deployment cost could have been about $28 million (US$21 million).
By contrast, purchasing an entire medium-lift launch vehicle typically costs tens of millions of dollars more. A dedicated SpaceX Falcon 9, the market benchmark, runs about $100 million (US$74 million).
While a whole rocket demands more upfront capital, it protects Kepler from the sudden price spikes hitting the rest of the rideshare sector. With SpaceX’s rideshare pipeline apparently closing, operators forced onto dedicated small-lift rockets face costs upwards of US$20,000 or more per kilogram. By securing a medium-lift vehicle, Kepler maintains economies of scale while gaining authority over its flight path.
The capacity play
Kepler’s shift to a dedicated rocket also reflects the growing physical size of its network. The company operates a commercial data relay constellation, essentially an orbital internet backbone that lets other satellites send data down to Earth in real time rather than waiting to pass over a ground station.
The first tranche of its optical network entered service earlier in 2026, equipped with on-orbit compute processing. The 2028 mission will expand those capabilities with updated hardware and capacity for hosted payloads, third-party instruments integrated to the Kepler satellite bus.
Rocket Lab’s Neutron is designed to carry up to 13,000 kilograms to low Earth orbit. At roughly 300 kilograms each, Kepler could theoretically fit more than 40 satellites on a single flight, although adapter mass and volume constraints will limit the practical total.
That capacity represents a sizeable leap over Rocket Lab’s existing small-lift vehicle, the Electron. An Electron can carry about 300 kilograms to orbit, meaning it could realistically lift only one of Kepler’s satellites at a time. Booking a medium-lift vehicle like Neutron allows Kepler to deploy a substantial portion of its expanded network in one stroke.
Escaping the launch vacuum
The contract insulates Kepler from a looming bottleneck for Canadian space operators. Canadian companies and government programs have been frequent users of SpaceX’s rideshare missions. Montreal-based GHGSat, the Canadian Space Agency and several universities have all built timelines around the SpaceX Transporter cadence.
When that capacity tightens after 2028, operators without secured launches will be left competing for space on foreign vehicles like India’s Polar Satellite Launch Vehicle, or waiting to see if Canada’s domestic sovereign-launch candidates — NordSpace, Canada Rocket Company, and Reaction Dynamics — hit their own 2028 targets. Kepler has avoided that scramble by buying the vehicle outright.
The 2028 launch date leaves a narrow margin for development schedules. Rocket Lab is positioning Neutron as a reusable competitor to the Falcon 9, and estimates commercial operations will scale between late 2026 and 2027, though in a recent investors call Rocket Lab did say the first launch could slip into early 2027.
For Kepler, the contract secures its place in line, but the company is not gambling its entire network expansion on an unproven rocket. Kepler stated the Rocket Lab mission is one of several launches planned for 2028. Because Neutron will be its first dedicated launch, those other would likely be rideshares. By securing a mix of dedicated and shared capacity, the company can continue its network expansion and hedge its bets against both the rideshare freeze and potential rocket delays.
The dedicated launch will be from Rocket Lab’s Complex 3 on Wallops Island, Virginia.
