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.

Rahul Gandhi meets family of ‘Mountain Man’ in Bihar

Patna, June 6: Congress leader Rahul Gandhi visited Dashrath Nagar village in Gaya district on Friday as part of his outreach efforts in Bihar ahead of the Assembly elections.
During his visit, he met the family of the late Dashrath Manjhi, popularly known as the “Mountain Man” for single-handedly carving a path through a hill in Gehlor village to connect it with Wajirganj block in the district.
Rahul Gandhi was received warmly by Bhagirath Manjhi, son of Dashrath Manjhi, who welcomed him with traditional hospitality.
The Congress leader sat with the family, shared coconut water, and listened to their concerns, including their financial hardships.
According to sources, Bhagirath Manjhi also expressed his interest in contesting the upcoming Bihar Assembly election from the Bodh Gaya constituency, though no official announcement was made.
Following his meeting in Dashrath Nagar, Gandhi proceeded to Gehlor village, where he garlanded the statue of Dashrath Manjhi as a mark of respect.
He was accompanied by Bhagirath Manjhi and later departed for Rajgir to attend a scheduled programme.
Earlier in the day, Gandhi landed at Gaya Airport, where he was welcomed by Congress leaders and supporters.
This marks Rahul Gandhi’s sixth visit to Bihar in 2025, so far, signalling a renewed push to strengthen the Congress’ presence at the grassroots level in the run-up to the Assembly elections.
Rahul Gandhi’s recent engagements in the state reflect the Congress party’s strategy to reconnect with local icons, marginalised communities, and symbolic figures, in an attempt to regain political ground in the state
Following his visit to Gaya, Rahul is scheduled to travel to Rajgir in Nalanda district to attend a Samvidhan Sammelan and return to Gaya to attend a ‘Mahila Samvad’ (Women’s Dialogue) programme and visit Mahabodhi temple in Bodh Gaya, as part of his outreach to marginalised communities and women across the state.

SC allows NBE to schedule NEET-PG 2025 exam on August 3

New Delhi, June 6: The Supreme Court on Friday allowed an application filed by the National Board of Examinations (NBE) seeking permission to schedule the National Eligibility-cum-Entrance Test (NEET)-PG 2025 on August 3.
A Bench of Justices Prashant Kumar Mishra and Augustine George Masih took note of the submission that August 3 was the earliest possible available date given by its technology partner for conducting the NEET-PG 2025 examination in terms of the recent apex court order.
Allowing the application filed by the NBE to conduct the NEET-PG 2025 examination on August 3, the Justice Mishra-led Bench clarified that no further time extension will be allowed by the top court.
In an order passed on May 30, the Supreme Court deprecated the practice of conducting the NEET-PG exam in two shifts and opined that holding the examination in two shifts leads to arbitrariness and cannot give a level playing field to the candidates.
It ordered the NBE to make necessary arrangements for holding the NEET-PG 2025 examination in one shift, duly ensuring that complete transparency is maintained and secure centres are identified and commissioned.
“The question papers in two shifts can never be of the same difficulty level. Last year, it (NEET-PG 2024) may have been held in two shifts in the facts and circumstances of that stage. But the examining body ought to have considered making arrangements for holding the examination in one shift,” the Supreme Court had remarked.
The apex court was dealing with a clutch of petitions challenging the lack of transparency in the conduct of the NEET-PG examination.
In their plea filed before the apex court, NEET-PG aspirants claimed that the introduction of two shifts, normalisation method, and change in the tie-breaker criterion affected medical students adversely. The petitioners said that NEET-PG had never been held in two shifts before and had always remained a single-shift and single-day examination to ensure a uniform examination standard and fairness of the national test.
