ISRO Launches X-Ray Polarimeter Satellite From First Launch-Pad, SDSC-SHAR In Sriharikota

Sriharikota: India Began 2024 with PSLV rocket lifting off with XPoSat Sriharikota (Andhra Pradesh). On the first day of the calendar year 2024, India’s Polar Satellite Launch Vehicle-C58 (PSLV-C58) on Monday morning lifted off with the country’s X-ray Polarimeter Satellite (XPoSat) with 10 other payloads.
The 44.4-metre tall PSLV-C58 rocket with a lift off mass of 260 ton carrying XPoSat and 10 other experimental payloads on its fourth stage blasted off from the first launch pad at the Satish Dhawan Space Centre (SDSC) here at 9.10 a.m. Slowly rising up towards the skies with a thick orange flame at its tail, the rocket gained speed with a sound resembling rolling thunder and went up and up leaving a thick plume while the people assembled at the viewing gallery clapped their hands with pride. Interestingly, this is the first space mission for ISRO on January 1 for the Indian Space Research Organisation (ISRO).
Procedure after 21 minutes into flight of rocket
At about 21 minutes into its flight, the rocket will orbit XPoSat at an altitude of about 650 km. Subsequently, the rocket’s fourth stage will be restarted twice to reduce the orbit into a 350 km circular orbit to maintain in 3-axis stabilised mode for Orbital Platform (OP) experiments.
The PSLV Orbital Experimental Module-3 (POEM-3) experiment will be executed, meeting the objective of 10 identified payloads, supplied by the ISRO and the Indian National Space Promotion and Authorisation Centre (IN-SPACe), the Indian space agency said.
In its normal configuration, the PSLV is a four-stage/engine expendable rocket powered by solid and liquid fuels, alternatively, with six booster motors strapped onto the first stage to give higher thrust during the initial flight moments.
ISRO’s five types of rockets
The ISRO has five types of PSLV rockets — Standard, Core Alone, XL, DL, and QL. The major difference between them is the use of strap-on boosters which, in turn, largely depends on the weight of the satellites to be orbited.
The PSLV uses 6,4,2 solid rocket strap-on motors to augment the thrust provided by the first stage in PSLV-XL, QL & DL variants, respectively. However, strap-ons are not used in the core-alone version (PSLV-CA). The XPoSat is the first dedicated scientific satellite from the ISRO to carry out research in space-based polarisation measurements of X-ray emission from celestial sources. The satellite configuration is modified from the IMS-2 bus platform.
Three objectives of XPoSat
The configuration of the mainframe systems is derived based on the heritage of IRS satellites. It carries two payloads, namely POLIX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing). The POLIX is realised by the Raman Research Institute and XSPECT is by the Space Astronomy Group of the U.R. Rao Satellite Centre (URSC).
According to the ISRO, the three objectives of XPoSat are: (a) To measure polarisation of X-rays in the energy band 8-30keV emanating from about 50 potential cosmic sources through Thomson Scattering by POLIX payload. (b) To carry out long-term spectral and temporal studies of cosmic X-ray sources in the energy band 0.8-15keV by XSPECT payload and (c) To carry out polarisation and spectroscopic measurements of X-ray emissions from cosmic sources by POLIX and XSPECT payloads, respectively, in the common energy band.
Passivation of PS4
After orbiting the XPoSat in 650km, the rocket’s fourth stage — PS4 stage — will be lowered to 350km, about 9.6 deg orbit, by restarting it twice. The left-out propellant in the PS4 will be disposed of through the main engines as a precursor to enabling the safety of the PS4 stage in atmosphere re-entry experiments planned in future. The oxidiser will be let out first followed by fuel in a predetermined sequence of operations. The existing scheme of spent stage passivation by venting the tank pressure will also be active.
Post passivation of PS4, the control of the stage is transferred to the POEM Avionics, the ISRO added. The POEM is configured as a 3-axis stabilised orbital platform for conducting experiments to space qualify systems with novel ideas. The PS4 Stage Orbital Platform Electrical power requirements are catered by a Flexible Solar Panel in conjunction with 50Ah Li-Ion battery in battery tied configuration.
Navigation process
The orbital platform consists of avionic systems to take care of navigation, guidance, control and telecommands and Orbital Platform Attitude Control System to cater to control of the platform to test the payloads, the ISRO said. The 10 payloads are from Take Me 2 Space, LBS Institute Technology for Women, K J Somaiya Institute of Technology, Inspecity Space Labs Private Ltd, Dhruva Space Private Ltd, Bellatrix Aerospace Private Ltd (two payloads) and three payloads from the ISRO.

DRI seizes 2 leopard skins, wild boar horn; two suspects apprehended

Bhopal, May 6: The Directorate of Revenue Intelligence (DRI) Nagpur unit, under the Mumbai Zonal jurisdiction, successfully apprehended two individuals engaged in illegal trade and possession of leopard skins.
Following the seizure, the confiscated wildlife articles and the detained individuals were handed over to the District Forest Division of Ujjain for further investigation in accordance with the Wild Life (Protection) Act, 1972.
The operation, conducted in Ujjain, Madhya Pradesh, resulted in the seizure of two leopard skins with heads, along with an ivory (wild boar horn), from the suspects.
Acting on specific Intelligence regarding attempts to sell these prohibited wildlife items, the DRI team intervened at a hotel in Ujjain on the morning of May 4 leading to the suspects’ capture.
The seized leopard skins and ivory were confiscated under the Wild Life (Protection) Act, 1972, which strictly prohibits the trade, purchase, or possession of leopard skins or any part of the animal, as leopards are listed under Schedule I of the Act.
The agency is active in various wildlife enforcement actions, including a recent operation in Rajasthan’s Rajsamand district, where it seized two leopard hides and 18 leopard nails, leading to the arrest of five individuals.
In March 2024, another mission in Vizag city resulted in the seizure of a leopard skin and the apprehension of four traffickers.
Additionally, DRI’s Pune unit intercepted a leopard skin in Akola, Maharashtra, leading to the arrest of three persons.
This operation is part of DRI’s ongoing efforts to combat wildlife trafficking.
Earlier in January 2025, the Nagpur unit intercepted three individuals in Maharashtra’s Akola district and recovered one leopard skin.
These successful missions reaffirm DRI’s steadfast commitment to curbing illegal wildlife trade and safeguarding India’s biodiversity.
Employing its Intelligence-based approach and enforcement capabilities, the DRI continues to dismantle trafficking networks and enforce wildlife protection laws in collaboration with other agencies.
