SOLARAS S2 is a 1U CubeSat developed by Grahaa Space as part of its early technology-demonstration initiatives. Scheduled for launch in 2025, the satellite is planned to fly aboard the Innospace HANBIT-NANO launch vehicle from the Alcântara Space Center in Brazil, targeting an orbit of approximately 500 km with an inclination of 40 degrees.[1][2][3][4][5][6] The mission is designed primarily for the observation of solar radiation and for transmitting telemetry and beacon signals that can be received by the amateur radio community.[1] As an open, non-commercial demonstration mission, SOLARAS S2 aims to encourage global participation in data collection, propagation studies, and satellite health monitoring. For Grahaa Space, the CubeSat serves as a platform to validate core subsystems particularly communications and payload interfaces and contributes to the company's broader roadmap for nanosatellite development and future constellation missions.
Overview
SOLARAS S2 is a nanosatellite developed by Grahaa Space as part of its technology demonstration and small-satellite development program. The mission is intended to test core satellite systems and support early-stage capability building for the company’s future nanosatellite constellation.
Mission objectives
The nanosatellite is designed to study solar radiation and to transmit continuous telemetry and beacon signals. These signals are intended for reception by the global amateur radio community, enabling participation in satellite monitoring, propagation analysis, and data decoding activities. In addition to technology demonstration, the mission is structured as a non-commercial, open-science initiative to promote educational engagement and collaborative research.[7]
Launch and orbit
SOLARAS S2 is planned for launch in November 2025 aboard the Innospace HANBIT-NANO launch vehicle from the Alcântara Space Center in Brazil. The satellite is expected to be deployed into a low Earth orbit at approximately 300 km altitude with an inclination of around 40 degrees.[7] The mission is part of a rideshare arrangement associated with the broader Spaceward launch campaign.
Role within Grahaa Space's roadmap
For Grahaa Space, SOLARAS S2 serves as a key milestone for qualifying the overall bus and platform. The mission contributes to the company’s long-term development of nanosatellite capabilities, supporting future plans for earth observation, real-time geospatial data, and constellation-based applications.[8]
