"Another milestone": ISRO rocket accomplishes zero orbital debris mission
Bengaluru (PTI): 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 developed indigenous systems. Out of these, six payloads were delivered by Non-Government Entities (NGEs) through Indian National Space Promotion and Authorization Centre (IN'?SPACe).
The mission objectives of these payloads were met in a month.
The orbital altitude of the upper stage continued to decay under the influence of natural forces, primarily atmospheric drag with the module (NORAD ID 58695) expected to have impacted the North Pacific Ocean (Lat 6.4 N & Long 158.7 W) on March 21, 2024, at 14:04 UTC (19:34 Hrs. IST), ISRO said.
Through the POEM, which serves as a very cost-effective platform for carrying out short-duration space-borne experiments, ISRO has opened up new vistas for academia, startups, and NGEs to experiment with their new payloads, it said.
This novel opportunity has been effectively utilised by numerous startups, universities, and NGEs for carrying out experiments in space, which included electric thrusters, satellite dispensers, and star-tracking.
POEM also incorporates new features such as total avionics in single-chain configuration, industrial-grade components in avionics packages including Mission Management Computer, standard interfaces for electric power, telemetry & telecommand, and new in-orbit navigation algorithms making use of rate-gyro, sun sensor, and magnetometer, the space agency said.
For the effective conduct of experiments onboard in POEM-3, the body rates were stabilised to less than 0.5 deg/s throughout, and innovative schemes like controlled dumping of residual propellant after the main mission were introduced for minimizing disturbances due to passivation, it added.
Noting that the Vikram Sarabhai Space Centre (VSSC) has taken the lead in conceptualising and realising the POEM by augmenting the 4th stage of PSLV, ISRO said PSLV-C58/XPoSat is the third such mission in the series, with POEMs being successfully scripted each time.
The payload operations were carried out effectively by the spacecraft operations team from the mission operations complex (MOX) at ISRO Telemetry Tracking and Command Network (ISTRAC) and ISRO's System for Safe and Sustainable Spacecraft Operations Management (IS4OM) has been monitoring and analysing the orbital decay all through, it said. Till near re-entry, POEM-3 was tracked by ISTRAC ground stations.
The Multi-Object Tracking Radar (MOTR) at Shriharikota also tracked the PS4 stage till the morning of March 21. POEM-3 was also supported by other Centres like U R Rao Satellite Centre (URSC), Liquid Propulsion Systems Centre (LPSC) and ISRO Inertial Systems Unit (IISU).
ISRO said it will continue its commitment to providing a cost-effective orbital experiment platform, as the growing menace due to space debris, especially with multiple small satellite constellations coming up, poses a significant threat to space activities, including satellite launches, human spaceflight, and space exploration missions.
ISRO, being a responsible space agency, is committed to mitigating this threat through the development and implementation of advanced debris tracking systems, space-object deorbiting technologies, and responsible satellite deployment practices, thus safeguarding orbital environments for present and future space endeavors, it added.

Karnataka offers extensive incentives in its proposed IT policy
Bengaluru (PTI): Karnataka has proposed a new Information Technology Policy for 2025–2030, offering extensive financial and non-financial incentives aimed at accelerating investments, strengthening innovation and expanding the state's tech footprint beyond Bengaluru.
The Karnataka Cabinet gave its nod to the policy 2025–2030 with an outlay of Rs 445.50 crore on Thursday after the Finance Department accorded its approval.
The policy introduces 16 incentives across five enabler categories, nine of which are entirely new, with a distinctive push to support companies setting up or expanding in emerging cities.
Alongside financial support, the government is also offering labour-law relaxations, round-the-clock operational permissions and industry-ready human capital programmes to make Karnataka a globally competitive 'AI-native' destination.
According to the policy, units located outside Bengaluru will gain access to a wide suite of benefits, including research and development and IP creation incentives, internship reimbursements, talent relocation support and recruitment assistance.
The benefits also include EPF reimbursement, faculty development support, rental assistance, certification subsidies, electricity tariff rebates, property tax reimbursement, telecom infrastructure support, and assistance for events and conferences.
Bengaluru Urban will receive a focused set of six research and development and talent-oriented incentives, while Indian Global Capability Centres (GCCs) operating in the state will be brought under the incentive net.
Incentive caps and eligibility thresholds have been raised, and the policy prioritises growth-focused investments for both new and expanding units.
Beyond incentives, the government focuses on infrastructure and innovation interventions.
A flagship proposal in the policy is the creation of Techniverse -- integrated, technology-enabled enclaves developed through a public-private partnership model inside future Global Innovation Districts.
These campuses will offer plug-and-play facilities, artificial intelligence and machine learning and cybersecurity labs, advanced testbeds, experience centres, and disaster-resistant command centres.
There will also be a Statewide Digital Hub Grid and a Global Test Bed Infrastructure Network, linking public and private research and development, and innovation facilities across Karnataka.
The government has proposed a Women Global Tech Missions Fellowship for 1,000 mid-career women technologists, an IT Talent Return Programme to absorb experienced professionals returning from abroad, and broad-based skill and faculty development reimbursements.
Shared corporate transport routes in Bengaluru and tier-two cities will be designed with Bengaluru Metropolitan Transport Corporation and other transport entities to support worker mobility.
The government said the policy is the outcome of an extensive research and consultation process involving TCS, Infosys, Wipro, IBM, HCL, Tech Mahindra, Cognizant, HP, Google, Accenture and NASSCOM, along with sector experts and stakeholder groups.
It estimates an outlay of Rs 967.12 crore over five years, comprising Rs 754.62 crore for incentives and Rs 212.50 crore for interventions such as Techniverse campuses, digital grid development, global outreach missions and talent programmes.
