1 . X-ray Polarimeter Satellite (XPoSat)

The Indian Space Research Organisation has announced a plan to launch its first X-ray Polarimeter Satellite (XPoSat) to investigate the polarisation of intense X-ray sources.

About XPoSat

  • XPoSat (X-ray Polarimeter Satellite) is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions.
  • The spacecraft will carry two scientific payloads in a low earth orbit.
  • The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin. The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV.


  • The emission mechanism from various astronomical sources such as blackhole, neutron stars, active galactic nuclei, pulsar wind nebulae etc. originates from complex physical processes and are challenging to understand. While the spectroscopic and timing information by various space based observatories provide a wealth of information, the exact nature of the emission from such sources still poses deeper challenges to astronomers.
  • The polarimetry measurements add two more dimension to our understanding, the degree of polarization and the angle of polarization and thus is an excellent diagnostic tool to understand the emission processes from astronomical sources.
  • The polarimetric observations along with spectroscopic measurements are expected to break the degeneracy of various theoretical models of astronomical emission processes. This would be the major direction of research from XPoSat by Indian science community.

XPoSat Payloads

  • POLIX : POLIX is an X-ray Polarimeter for astronomical observations in the energy band of 8-30 keV. The payload is being developed by Ramam Research Institute (RRI), Bangalore in collaboration with U R Rao Satellite Centre (URSC). The instrument is made of a collimator, a scatterer and four Xray proportional counter detectors that surrounds the scatterer. The scatterer is made of low atomic mass material which causes anisotropic Thomson scattering of incoming polarised X-rays. The collimator restricts the field of view to 3 degree x 3 degree so as to have only one bright source in the field of view for most observations. POLIX is expected to observer about 40 bright astronomical sources of different categories during the planned lifetime of XPoSat mission of about 5 years. This is the first payload in the medium X-ray energy band dedicated for polarimetry measurements.
  • XSPECT : XSPECT is an X-ray SPECtroscopy and Timing payload onboard XPoSat, which can provide fast timing and good spectroscopic resolution in soft X-rays. Taking advantage of the long duration observations required by POLIX to measure X-ray polarization, XSPECT can provide long-term monitoring of spectral state changes in continuum emission, changes in their line flux and profile, simultaneous long term temporal monitoring of soft X-ray emission in the X-ray energy range 0.8- 15 keV. An array of Swept Charge Devices (SCDs) provide an effective area >30 cm2 at 6 keV with energy resolution better than 200 eV at 6 keV. Passive collimators are used to reduce the background by narrowing the field of view of XSPECT. XSPECT would observe several types of sources viz X-ray pulsars, blackhole binaries, low-magnetic field neutron star (NS) in LMXBs, AGNs and Magnetars

2 . Loss and Damage Fund

Context : On the first day of the 28th Conference of Parties or COP-28 here on Thursday, member countries agreed to make operational a Loss and Damage (L&D) Fund meant to compensate countries already dealing with climate change.

About Loss and Damage Fund

  • The World Bank will be the “interim host” of the Fund for a period of four years. It will be managed by an independent secretariat.
  • All developing countries are eligible to apply for and every country has been “invited” to contribute to the Fund. Payments are voluntary and a certain percentage has been set apart for a category of countries called the Least Developed Countries and Small Island Developing States.
  • Fund has received commitments worth nearly $250 million from countries, though billions of dollars are still needed to meet its purpose. The UAE, the host country, and Germany made a financial commitment of $100 million each; the U.S. $17 million, the U.K. approximately $50.6 million, and Japan $10 million for the Fund. The European Union committed $145 million, over and above the German contribution.


  • Loss and damage from climate change cost about $1.5 trillion ($1,500 billion) in 2022, says a study published by the University of Delaware. Several developing countries and some of the poorest lost an average of about 8.3% of the GDP due to climate change. The Fund, as it stands now, does not specify how often it will be replenished.

What is Loss and Damage

  • Loss and damage refers to the negative consequences that arise from the unavoidable risks of climate change, like rising sea levels, prolonged heatwaves, desertification, the acidification of the sea and extreme events, such as bushfires, species extinction and crop failures.
  • As the climate crisis unfolds, these events will happen more and more frequently, and the consequences will become more severe.


  • At the 19th Conference of the Parties (COP 19) to the United Nations Framework Convention on Climate Change (UNFCCC) in Warsaw, Poland, in 2013, representatives of member countries formally agreed to establish the L&D fund. It was being created to provide financial and technical assistance to economically developing nations that were incurring L&D due to climate change. 
  • At COP 25, the Santiago Network for L&D was set up, but countries failed to commit any fund. 
  • At COP 26, the Glasgow Dialogue on finance for L&D was established to continue discussions over the next three years on the fund. 
  • Finally, at COP 27 in 2022, after intense negotiations, representatives of the UNFCCC’s member states agreed to set up the L&D fund and a Transitional Committee (TC) to figure out how the new funding mechanisms under the fund would operate. The TC was also to prepare recommendations that countries would consider, deliberate on, and potentially adopt by COP 28. 

How much loss and damage is the world facing?

  • Research shows that 55 vulnerable countries have suffered $ 525 billion combined climate crisis-fuelled losses in the last 20 years. The number is estimated to reach $ 580 billion per year by 2030. Global warming has changed the way the world lives, with vulnerable communities being the worst affected.
  • According to the IPCC, losses and damages will increase in future as global warming continues to rise. It will be unequally distributed and impact developing nations the most and, in them, the socially and financially weaker sections.

How will L&D funds ensure climate justice? 

  • Adaptation and L&D are not mutually exclusive concepts. They exist on a continuum of climate resilience, and both have a place in the collective efforts to combat climate change. 
  • A successful response to climate change requires balancing of the proactive measures of adaptation with the moral and financial responsibility of addressing the losses and damages that are an inescapable part of a climate-altered world. 
  • The L&D fund was conceived as a critical component of global climate action, recognising that some of the consequences of climate change are irreversible and beyond the capacity of vulnerable nations to handle. 
  • To achieve climate justice, rich countries must meet their obligations to reduce emissions and deliver finance in line with what is fair, and uphold the principles of equity, justice, and solidarity in the face of a changing climate. 
  • Otherwise, global climate action will get derailed, putting more pressure on the already beleaguered COP 28 talks. 

3 . DAC

Context : In a major move to enhance the combat capabilities of the armed forces significantly, the Union government accorded initial approval to defence acquisition projects estimated at ₹2.23 lakh crore that included procurement of 97 Tejas light combat aircraft and 156 Prachand combat helicopters.

Details of the projects cleared by DAC

  • The DAC approved a proposal of the Indian Air Force to upgrade its Su-30 fighter fleet by state-run aerospace major Hindustan Aeronautics Ltd. It further accorded Acceptance of Necessity (AoN) or initial approval for procurement of two types of anti-tank munitions namely area denial munition (ADM) Type-2 and -3.
  • The top body on procurement of military hardware also cleared acquisition and integration of automatic target tracker (ATT) and digital basaltic computer (DBC) for T-90 tanks besides approving another proposal to buy medium-range anti-ship missiles (MRAShM) for the Navy.

4 . Green Credit Initiative

Context : Refraining from fresh commitments to contain global temperature rise, Prime Minister Narendra Modi in his address at COP-28, offered to host the 33rd edition of the annual summit due in 2028 in India. He said that developed countries ought to be “vacating the carbon space” before 2050 and made a pitch for the world’s countries to join India on its “Green Credit initiative” which was a “non-commercial” effort to create a carbon sink.

What is Green Credit Initiative?

  • The Green Credit Initiative was first introduced by the ministry of environment, forest and climate change on October 13, 2023. There are two main priorities of the initiative – water conservation and afforestation.
  • The environment ministry defined the initiative as a “market-based mechanism designed to incentivize voluntary environmental actions across diverse sectors by various stakeholders like individuals, communities, private sector industries, and companies.”
  • Under this scheme, green credits will be assigned to specific environmental activities, and will be treated as tradable commodities. These green credits will be able to be sold on domestic market platforms.
  • The main purpose of this initiative is to boost voluntary environmental activities like tree plantation, water conservation, sustainable agriculture, and waste management by incentivizing it for big corporations and private companies, bringing about a change in the climate issues faced by the country.
