ISRO Successfully Tests Indigenous Electric Propulsion System.

Science & Technology | Dated: 10 Mar 2026

In a major technological breakthrough, the Indian Space Research Organisation (ISRO) successfully tested its indigenous Electric Propulsion System (EPS) for satellites in orbit. The EPS significantly reduces satellite weight by replacing bulky liquid chemical propellants.

🎯 Key Highlights:

  • The system runs efficiently using solar energy and inert gases like Argon or Xenon.
  • It dramatically increases the operational lifespan of communication satellites.
  • The EPS was developed entirely at the Liquid Propulsion Systems Centre (LPSC).

💡 Other Important Facts:

  • Test: Electric Propulsion System.
  • Agency: ISRO.
  • Benefit: Reduces Weight.
