Mumbai’s Manastu Space Tests Green Propulsion System in Space

02 Jan 2025 CW Team

Mumbai-based space startup Manastu Space announced on Wednesday that it had successfully tested its self-developed thruster, Vyom 2U, onboard the PSLV Orbital Experimental Module-4 (POEM). This test, which occurred on New Year’s Eve, involved tilting the platform by 24 degrees and imparting angular velocity before the onboard systems regained control.

The POEM-4 platform, which forms part of the PSLV-C60 rocket launched carrying the SpaDeX satellites, was placed in orbit at an altitude of 350 km. The platform will be used for in-orbit experiments by ISRO labs, startups, and educational institutions.

Tushar Jadhav, founder and CEO of Manastu Space, stated, "The 30-second test firing tilted the POEM-4 platform by 24 degrees, imparting an angular velocity of 0.5 degrees per second before the systems took control again."

The Vyom 2U thruster uses MS289 green propellant, a blend of hydrogen peroxide, replacing the hazardous hydrazine-based propellants previously used in satellites.

Manastu expressed gratitude to ISRO and IN-SPACe for providing the platform to test their green propulsion system. Other experiments on the POEM-4 include seed germination in space, a robotic arm to capture tethered debris, and various space technology demonstrations.

The POEM platform is hosting 24 experiments, with 14 from ISRO labs and 10 from startups and private universities, providing an accessible platform for space technology development.

Mizoram To Build Rs 139 Billion Pumped Storage Power Plant

Mizoram Chief Minister Lalduhoma on Friday announced plans to construct a 2,400 MW pumped storage hydroelectric power plant in Hnahthial district, marking a major step towards achieving energy self-sufficiency in the state. Addressing the Mizo Students’ Union general conference in Hnahthial town, the Chief Minister said the plant would be developed across the Darzo Nallah, a tributary of the Tuipui river. Once operational, the project is expected to play a pivotal role in meeting Mizoram’s rising electricity demand and reducing dependence on imported power. Officials from the State Power..

Centre Plans Nationwide Opening Of Power Retail Market

India is preparing to open up its retail electricity market to private companies nationwide, effectively ending the long-standing monopoly of state-run power distributors in most regions, according to a draft bill released by the Union Power Ministry on Friday. The move will enable major private sector players — including Adani Enterprises, Tata Power, Torrent Power, and CESC — to expand their presence across the country’s electricity distribution landscape. A similar reform attempt in 2022 had faced strong opposition from state-run distribution companies (discoms), which currently dom..

CEA Sets 100 GW Nuclear Target For India By 2047

In a landmark step marking its 52nd Foundation Day, the Central Electricity Authority (CEA) unveiled an ambitious roadmap to develop 100 gigawatts (GW) of nuclear power capacity by 2047, aligning with India’s long-term Net-Zero commitment and energy security objectives. The event, held at the Central Water Commission auditorium in New Delhi’s R.K. Puram, was attended by Pankaj Agarwal, Secretary, Ministry of Power, who served as the Chief Guest. The roadmap sets out a detailed plan to expand India’s nuclear capacity from its current level of approximately 8,180 MW as of early 2025, outl..
