Answer: Indian Space Research Organisation (ISRO)
Notes: ISRO successfully demonstrated the restart of its Vikas liquid engine at the Propulsion Complex, Mahendragiri. The test is a significant step towards developing reusable launch vehicle technologies to reduce future space mission costs. The Vikas engine, named after Dr. Vikram Sarabhai, was conceptualized and designed by ISRO's Liquid Propulsion Systems Centre (LPSC). LPSC specializes in designing and developing liquid propulsion stages for ISRO's launch vehicles. The Vikas engine powers the liquid stages of PSLV, GSLV, and GSLV Mk-III launch vehicles, enhancing their payload capacities.
