India's space endeavors in 2024 are set to commence with a launch on the first day of the year. The Indian Space Research Organisation (ISRO) is currently in the final stages of pre-launch activities, preparing to deploy the X-Ray Polarimeter Satellite (XPoSat) aboard a Polar Satellite Launch Vehicle (PSLV). Following the deployment of the main satellite, the PSLV's last stage will carry an additional 10 payloads.
 
In addition to XPoSAT, the primary satellite, the PSLV mission will transport an additional 10 payloads or instruments into space using its final stage, known as the PSLV Orbital Experimental Module, or POEM.
 
Space Startups Launch Cutting-Edge Technologies
 
The five instruments included on the POEM platform, as detailed by ISRO, are:
 
Radiation Shielding Experimental Module (RSEM): Designed to assess the effectiveness of Tantalum coating, developed by TakeMe2Space, Hyderabad.
 
Women Engineered Satellite (WESAT): Aims to measure Solar Irradiance and UV Index, crafted by LBS Institute of Technology for Women.
 
BeliefSat-0: An amateur radio satellite created by KJ Somaiya Institute of Technology.
 
Green Impulse Transmitter (GITA): A green bipropellant CubeSat propulsion unit from Inspecity Space Labs Private Limited.
 
Launching Expeditions for Aspiring Technologies - Technology Demonstrator (LEAP-TD): For demonstrating microsatellite subsystems, by Dhruva Space.
 
Other 5 includes
 
RUDRA 0.3 HPGP and ARKA-200: Two instruments from Bengaluru's Bellatrix Aerospace; RUDRA 0.3 HPGP is a green monopropellant thruster, and ARKA-200 is a heater-less hollow cathode for Hall thrusters.
 
Fuel Cell Power System (FCPS) and Silicon-based High Energy Cell: Two payloads developed by ISRO's Vikram Sarabhai Space Centre (VSSC); FCPS for fuel cell demonstration and a Silicon-based high energy cell.
 
Dust Experiment (DEX); A payload from Physical Research Laboratory (PRL) designed to measure the interplanetary dust count.
 
"PSLV's POEM: Pioneering Orbital Space Experiments"
 
The POEM (PSLV Orbital Experimental Module) is an innovative platform utilized for performing experiments in space, making use of the final stage of ISRO's Polar Satellite Launch Vehicle (PSLV). The PSLV is a rocket with four stages. The initial three stages drop into the ocean after use, while the final stage (PS4), typically left as space debris, is repurposed in POEM for conducting orbital experiments after delivering the satellite to its orbit.
 
During the PSLV-C53 mission, the final stage, after being expended, will serve as a "stabilized platform" for various experiments. This mission marks the first instance where the PS4 stage, through the POEM platform, will orbit the Earth as a stabilized platform for conducting experiments.
 
The PSLV Orbital Experimental Module (POEM) is equipped with a specialized Navigation Guidance and Control (NGC) system to maintain stable orientation in space. It is powered by solar panels mounted around the PS4 tank, supplemented by a lithium-ion battery. For navigation, POEM utilizes an array of four sun sensors, a magnetometer, gyroscopes, and the NavIC system.
 
"PS4 Fuel Tank: POEM's Core"
 
The term "PS4 tank" refers to the fuel tank of the fourth stage (PS4) of the Polar Satellite Launch Vehicle (PSLV). In a multi-stage rocket like the PSLV, each stage has its own engines and fuel tanks. The PS4 is the uppermost stage of the PSLV, responsible for placing the satellite into its final orbit. The fuel tank in this stage, known as the PS4 tank, holds the propellant needed for this final push. In the context of the PSLV Orbital Experimental Module (POEM), solar panels are installed around this tank, utilizing the structure of the PS4 stage even after its primary function of satellite deployment is completed.

New Delhi: Assam Chief Minister Himanta Biswa Sarma on Tuesday said that four to five lakh “Miya voters” would be removed from the electoral rolls in the state once the Special Intensive Revision (SIR) of voter lists is carried out. He also made a series of controversial remarks openly targeting the Miya community, a term commonly used in Assam in a derogatory sense to refer to Bengali-speaking Muslims.

Speaking to reporters on the sidelines of an official programme in Digboi in Tinsukia district, Sarma said it was his responsibility to create difficulties for the Miya community and claimed that both he and the BJP were “directly against Miyas”.

“Four to five lakh Miya votes will have to be deleted in Assam when the SIR happens,” Sarma said, adding that such voters “should ideally not be allowed to vote in Assam, but in Bangladesh”. He asserted that the government was ensuring that they would not be able to vote in the state.

The chief minister was responding to questions about notices issued to thousands of Bengali-speaking Muslims during the claims and objections phase of the ongoing Special Revision (SR) of electoral rolls in Assam. While the Election Commission is conducting SIR exercises in 12 states and Union Territories, Assam is currently undergoing an SR, which is usually meant for routine updates.

Calling the current SR “preliminary”, Sarma said that a full-fledged SIR in Assam would lead to large-scale deletion of Miya voters. He said he was unconcerned about criticism from opposition parties over the issue.

“Let the Congress abuse me as much as they want. My job is to make the Miya people suffer,” Sarma said. He claimed that complaints filed against members of the community were done on his instructions and that he had encouraged BJP workers to keep filing complaints.

“I have told people wherever possible they should fill Form 7 so that they have to run around a little and are troubled,” he said, adding that such actions were meant to send a message that “the Assamese people are still living”.

In remarks that drew further outrage, Sarma urged people to trouble members of the Miya community in everyday life, claiming that “only if they face troubles will they leave Assam”. He also accused the media of sympathising with the community and warned journalists against such coverage.

“So you all should also trouble, and you should not do news that sympathise with them. There will be love jihad in your own house.” He said.

The comments triggered reactions from opposition leaders. Raijor Dal president and MLA Akhil Gogoi said the people of Assam had not elected Sarma to keep one community under constant pressure. Congress leader Aman Wadud accused the chief minister of rendering the Constitution meaningless in the state, saying his remarks showed a complete disregard for constitutional values.

According to the draft electoral rolls published on December 27, Assam currently has 2.51 crore voters. Election officials said 4.78 lakh names were marked as deceased, 5.23 lakh as having shifted, and 53,619 duplicate entries were removed during the revision process. Authorities also claimed that verification had been completed for over 61 lakh households.

On January 25, six opposition parties the Congress, Raijor Dal, Assam Jatiya Parishad, CPI, CPI(M) and CPI(M-L) submitted a memorandum to the state’s chief electoral officer. They alleged widespread legal violations, political interference and selective targeting of genuine voters during the SR exercise, describing it as arbitrary, unlawful and unconstitutional.
