With successful in-orbit tests, space startups validate technology on ISRO’s POEM platform

Under its standard configuration, ISRO’s PSLV rocket is a four-stage rocket. The first three spent stages fall back into the ocean, while the final stage (P4) ends up in space as junk after launching satellites into the orbit. However, the POEM initiative uses the spent final stage as a “stabilised platform to perform experiments.

Aboard the POEM mission, Hyderabad-based Dhruva Aerospace validated its P-30 satellite platform and its subsystems, and Bengaluru-based Bellatrix Aerospace validated its Rudra and Arka propulsion systems.

✅ MISSION SUCCESS

Dhruva Space is open for business as a hosted payload solution provider; declares success of #LEAPTD platform, onboard @isro’s PSLV-C58 POEM-3.

Bellatrix’s Rudra green propulsion system replaces the hazardous propellant hydrazine with one that is non-toxic, environment-friendly and high-performing, according to the company. Its Arka electric engine can propel spacecraft using electricity instead of chemical propellants.
