The vehicle
From launch orbit
to working orbit.
Kalpana is Pascal’s orbital transfer vehicle in development. It’s designed to carry payloads from launch to their planned destination in low Earth orbit, or support them on board.
Restartable propulsion is central to the design: enabling a sequence of manoeuvres within a defined mission envelope.
Payload design target
Up to 300 kg
Initial mission scope
Low Earth orbit
Development status
Pre-flight
Kalpana has not flown. Capabilities shown here are design targets, subject to engineering validation and mission planning.
Planned services
A vehicle.
More than one purpose.
Orbital delivery
From your launch orbit to your working orbit.
Payloads travel attached to Kalpana from launch. The planned delivery envelope covers altitude and phasing changes in low Earth orbit, followed by deployment.
The first vehicle’s scope does not include docking, retrieving satellites, or arbitrary plane changes.
Discuss a delivery missionHosted payloads
Bring the instrument. Stay on board.
Kalpana is being designed to carry hosted instruments through a mission, with shared vehicle resources and operations. Payload fit, interfaces, and operating needs are part of mission planning.
Hosting capabilities and resource allocations remain under development.
