LEAP-2 Mission

Launching Expeditions for Aspiring Payloads - 2

LEAP-2 is Dhruva Space’s second commercial endeavour on the P-30 satellite platform, hosting XXX In-Orbit Demonstration (IOD) missions for global customers: France-based Sodern Arianegroup’s HORUS Star Tracker, India-based Satleo Labs’ TAPAS-1 thermal infrared sensor, a XYZ payload developed in partnership with India-based QNu Labs, and an internal AIS payload of Dhruva Space.

This mission is slated to be launched via SpaceX’s Falcon 9 on XXX MM 2026. 
[The rocket launched from Vandenberg Space Force Base, California, USA, at XXXX pm / am IST followed by successful deployment of the LEAP-2 satellite at XXXX am/pm IST.]

About Dhruva Space's Launching Expeditions for Aspiring Payloads (LEAP) programme:
‍
The LEAP hosted payload programme by Dhruva Space offers organisations a flight-proven satellite bus platform designed for seamless payload accommodation and mission deployment. Built on a foundation of modular avionics, scalable power distribution, and adaptable communication interfaces, this solution enables customers to bypass the complexity of spacecraft development while retaining mission flexibility.

Through this programme, Dhruva Space delivers end-to-end services — from satellite bus and subsystems development, payload integration, environmental testing, to Launch coordination and integration, Ground segment readiness, and compliant deorbiting at end-of-life.

Customers benefit from:
Accelerated time-to-orbit
Shared mission economics: Reduced capital expenditure via co-flying opportunities
Full-stack reliability: Integrated mission critical subsystems for robust mission assurance

LEAP empowers innovators to focus on their core technology while Dhruva Space handles the satellite bus, mission assurance, and orbital infrastructure. It’s a platform built for rapid deployment, scalability, and global collaboration, enabling faster access to Space.
