Why in the news

CE20 showed it can ignite and stabilise unaided, a step towards flexible missions with several restarts.

Key facts

  • Test site: High-Altitude Test Facility, ISRO Propulsion Complex.
  • Conditions simulated space through a vacuum.

Why it matters

  • Less hardware improves flexibility and launch efficiency.
  • Saved mass may raise LVM3 payload capacity.
  • Helps multi-orbit, interplanetary and human spaceflight missions.

Exam angle

  • Engine: CE20; launcher: LVM3.

Test yourself

1. ISRO demonstrated bootstrap mode start on which engine?

The CE20 cryogenic engine was tested.

2. Where was the CE20 bootstrap mode test conducted?

It was done at the HAT Facility, Mahendragiri.

3. What does bootstrap start remove the need for at each restart?

It removes start-up gas bottles required in current systems.
