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 (PTI): The Supreme Court on Thursday remarked that if individuals start questioning certain religious practices or matters of religion before a constitutional court then there will be hundreds of petitions questioning different rituals, leading to the breaking of religions and the civilisation.

The nine-judge Constitution bench is hearing petitions related to discrimination against women at religious places, including the Sabarimala temple in Kerala, and on the ambit and scope of the religious freedom practised by multiple faiths, including Dawoodi Bohras.

The bench comprises Chief Justice of India (CJI) Surya Kant and Justices B V Nagarathna, M M Sundresh, Ahsanuddin Amanullah, Aravind Kumar, Augustine George Masih, Prasanna B Varale, R Mahadevan and Joymalya Bagchi.

The Central Board of Dawoodi Bohra Community filed a PIL in 1986 seeking the setting aside of a 1962 judgment, which had struck down the Bombay Prevention of Excommunication Act, 1949 -- this law made excommunication of any community member illegal.

The 1962 Constitution bench judgment said, "It is evident from the religious faith and tenets of the Dawoodi Bohra community that the exercise of the power of excommunication by its religious head on religious grounds formed part of the management of its affairs in matters of religion and the 1949 Act in making even such excommunication invalid, infringed the right of the community under Article 26(b) of the Constitution."

Senior advocate Raju Ramachandran, representing a group of reformist Dawoodi Bohras, submitted that a practice which is conducted in response to secular and social actions of an individual cannot be the subject of Constitutional protection under Article 25 of the Constitution and consequently cannot be a ‘matter of religion’ under Article 26 of the Constitution.

Ramachandran told the court that a practice which may have a religious aspect but also significantly and adversely impacts fundamental rights is not immune to restriction under Article 25 of the Constitution or Article 26 of the Constitution.

Responding to the submission, Justice Nagarathna said that if everybody starts questioning certain religious practices or matters of religion before a constitutional court, then "what happens to this civilisation where religion is so intimately connected with the Indian society".

"There will be hundreds of petitions questioning this right that right, opening of the temple, and the closure of the temple. We are conscious of this," she said.

Adding to the response, Justice Sundresh said, "Every religion will break and every constitutional court will have to be closed.

"If the dispute between two entities are allowed then everybody will question everything. In your case there may be a civil wrong committed to you but in another case, another member will say I don't agree. It is regressive. To what extent can we go in a country like ours which is progressive and on the move is the question," he said.

Justice Nagarathna went on that what sets apart India from any other region is that "we are a civilisation" despite having so many pluralities and diversities?

Asserting that diversity is the country's strength, she added, "One of the constants in our Indian society is the relationship of human beings -- man, woman and child -- with the religion."

"Now, how a religious practice or a matter of religion is questioned, where it is questioned, whether it can be questioned, whether it has to be a question within a denomination for a reform or whether the state will have to do or you want the court to adjudicate upon all these aspects. This is troubling us.

"What we lay down, is for a civilisation that is India. India must progress despite all its economy, everything there is a constant in us. We can’t break that constant. That is what is troubling us ," she said.

Ramachandran replied that India is a civilisation under the Constitution and therefore nothing which goes against the grain of constitution can be continued in a civilised society.

He said that's where court's task come in and "it can't throw hands" and say there will be so many petitions.
