Upper Stage of PSLV-37 rocket enters earth's atmosphere as predicted: Isro

The upper stage of PSLV-37 rocket, which launched a record number of 104 satellites more than seven years ago, has re-entered the earth's atmosphere as predicted, the Indian Space Research Organisation announced on Tuesday. PSLV-C37 was launched on February 15, 2017 with Cartosat-2D as the main payload along with another 103 satellites as co-passengers. It created history as the first mission to launch 104 satellites with a single vehicle, the Bengaluru-headquartered national space agency noted in a statement. After injecting the satellites and passivation, the upper stage (PS4) was left at an orbit of approximately 470 x 494 km size. It was regularly tracked and its orbital altitude slowly decayed, primarily due to atmospheric drag effects, it said. Since September 2024, IS4OM (ISRO System for Safe and Sustainable Space Operations Management) regularly monitored the orbital decay as part of its regular activities and predicted the re-entry into the atmosphere in October first week.

Isro completes Reusable Launch Vehicle tech demonstrations with LEX trio

Space agency ISRO on Sunday said it has achieved a third consecutive success in the Reusable Launch Vehicle Landing Experiment by demonstrating the autonomous landing capability of the launch vehicle under more challenging conditions. This mission simulated the approach and landing interface and high-speed landing conditions for a vehicle returning from space, reaffirming the Indian Space Research Organisation's (ISRO) expertise in acquiring the most critical technologies required for the development of a Reusable Launch Vehicle (RLV), the space agency said. The third and final test in the series of Landing Experiment (LEX-03) was conducted at 07:10 1ST at the Aeronautical Test Range (ATR) in Chitradurga, Karnataka. Following the success of the RLV LEX-01 and LEX-02 missions, ISRO in a release said, RLV LEX-03 re-demonstrated the autonomous landing capability of the RLV under more challenging release conditions (cross range of 500 m against 150 m for LEX-02) and more severe wind ...

'Another milestone': Isro's PSLV accomplishes zero orbital debris mission

ISRO on Monday said its Polar Satellite Launch Vehicle (PSLV) has accomplished zero orbital debris mission, and described it "another milestone". This was achieved on March 21, when the PSLV Orbital Experimental Module-3 (POEM-3) met its "fiery end" through a re-entry into the Earth's atmosphere. "The PSLV-C58/XPoSat mission has practically left zero debris in orbit," the space agency said. The PSLV-C58 mission was accomplished on January 1. According to ISRO, after completing the primary mission of injecting all satellites into their desired orbits, the terminal stage of PSLV was transformed into a 3-axis stabilised platform, the POEM-3. The stage was deorbited from 650 km to 350 km, which facilitated its early re-entry, and was passivated to remove residual propellants to minimise any accidental break-up risks, it said. POEM-3 was configured with a total of nine different experimental payloads to carry out technology demonstrations and scientific experiments on the newly ...
