The testing at Sriharikota evaluated redesigns to the solid motor, such as reinforced interfaces and sealing redundancy, to address the third-stage burn failures. In addition to hardware updates, technicians revised raw material standards, motor assembly procedures, and non-destructive testing protocols during integration and transportation. Agency officials will now perform a detailed analysis of the ground test data before scheduling further validation tests. This thorough review aims to restore operational reliability to the four-stage launch system.

Isro successfully tests modified PSLV third stage after two consecutive launch failures, with further checks planned.
BENGALURU: In an important step towards restoring the reliability of its workhorse Polar Satellite Launch Vehicle (PSLV), Isro Thursday said it successfully conducted a ground static test of the rocket’s modified third stage (PS3) at the Satish Dhawan Space Centre (SDSC) in Sriharikota.The test, conducted on Thursday, follows two consecutive PSLV mission failures in which anomalies were observed in the rocket’s third stage. Isro said it had comprehensively reviewed the stage’s design margins, raw material acceptance criteria, assembly procedures and quality checks before introducing modifications to strengthen the system.Isro said the modified PS3 solid motor incorporates improvements to its nozzle configuration and mechanical interfaces, along with additional redundancy in its sealing systems. The space agency has also revised procedures for accepting raw materials, assembling the motor and conducting non-destructive tests (NDT) during integration and transportation.The mechanical interfaces have also been strengthened, with redundancy introduced in the sealing systems. Isro said the adequacy of design margins had been verified and updated non-destructive testing procedures had…
The European Space Agency's Euclid mission has published its first major dataset covering roughly 14% of its planned observation area. This initial release aims to help scientists investigate dark energy and dark matter, which together comprise about 95% of the cosmos. By studying how light distorts around distant formations, researchers hope to map invisible matter and test competing cosmological theories.
Astronomers have gained access to a vast new cosmic catalog provided by the Euclid space mission. The release offers unprecedented scope for researchers analyzing large-scale structures across deep space. It marks a significant milestone in efforts to map the universe.
European Space Agency researchers are analyzing cosmic growth and gravitational phenomena to decode dark energy and dark matter, which together comprise roughly 95 percent of the cosmos. Tracking galactic positions across 10 billion years will allow scientists to reconstruct the universe's large-scale three-dimensional structure. Initial scientific conclusions regarding these invisible forces are scheduled for completion next year.
