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.

Suspicious passenger apprehended at Delhi Jama Masjid Metro Station after trying to flee during screening

Alert personnel of the Central Industrial Security Force (CISF) apprehended a passenger at Delhi’s Jama Masjid Metro Station after he allegedly attempted to flee when a suspicious object was detected during his baggage screening.
According to the CISF, the incident came to light when the passenger’s baggage was being screened through an X-ray Baggage Inspection System (XBIS). During the examination, personnel noticed a dense and suspicious object on the scanner screen.
Sensing something unusual, the security personnel attempted to examine the matter further. However, the passenger allegedly tried to escape from the screening area, according to CISF.
Displaying promptness and alertness, CISF personnel immediately chased him and apprehended him near the station’s exit gate before he could leave the premises.
A subsequent examination of his belongings led to the recovery of an unidentified semi-solid substance concealed inside a stitched portion of his undergarment, the CISF said.
According to reports, the passenger reportedly claimed to be a non-resident Indian (NRI) residing in Kuala Lumpur, Malaysia.
Following the recovery, the CISF handed over the passenger, along with his belongings and the suspected substance, to the police for further investigation.
The nature of the semi-solid substance and the reason behind its concealment remain unclear. Police are investigating the matter to establish the identity of the substance and determine the circumstances surrounding the incident.
The CISF’s swift intervention prevented the passenger from leaving the station without further examination.
The force said its personnel remain alert during the screening of passengers and their baggage to ensure compliance with security protocols and prevent any potential threat to metro commuters. Further action in the case will depend on the findings of the investigation, said the police officials.

Bihar MLC election: Three FIRs filed against Anant Singh, Jan Suraaj candidate Anuj Singh

Amid campaigning for the biennial elections for eight MLC seats on October 23 in Bihar, police have registered three FIRs in connection with alleged violation of election rules during a roadshow in the Mokama Assembly constituency of Patna district.
The roadshow was held on Sunday. The cases have been registered against local MLA Anant Singh and Jan Suraaj candidate Anuj Singh, according to police sources.
Of the three cases, two were registered at Barh police station and one at Mokama police station in Patna district.
The police are investigating the alleged violations and examining the circumstances surrounding the roadshow.
According to police sources, the action followed complaints of violations of the Model Code of Conduct and other applicable regulations during the Member of Legislative Council (MLC) election-related event.
The allegations concern compliance with rules governing political roadshows and public campaigning.
However, the specific allegations against each leader and the legal sections invoked in the FIRs have not yet been independently confirmed.
The registration of the cases has triggered political discussions in the Mokama and Barh areas, where election-related activities have intensified.
During the MLC election period, candidates and political parties are required to comply with the Model Code of Conduct and applicable rules governing public meetings, roadshows, permissions and traffic management.
Authorities can initiate legal action when alleged violations are reported.
However, the filing of an FIR does not establish guilt. The allegations against Anant Singh and Anuj Singh will be subject to investigation and the due process of law.
Police said further action would be taken on the basis of the evidence collected and the findings of the investigation.
Additional details are awaited.
Anant Singh, the JD(U) MLA from Mokama in Patna district, has openly extended his support to Jan Suraaj candidate Anuj Singh and is campaigning against his own party’s official nominee, Neeraj Kumar, in the upcoming MLC election.
Anant Singh said his decision to support Anuj Singh stemmed from a personal dispute with Neeraj Kumar. He clarified that his move had nothing to do with his political relationship with the JD(U).
The election for eight Legislative Council seats is scheduled to be held on October 23, with counting of votes and announcement of results set for October 27.

‘Owaisi, BJP are twins’: Congress MP accuses AIMIM chief of splitting Oppn votes

Congress MP Pramod Tiwari on Monday hit back at AIMIM chief Asaduddin Owaisi over his recent remarks, accusing him of acting as an agent of the Bharatiya Janata Party (BJP).
Tiwari claimed that election results demonstrated how Owaisi’s party had contributed to splitting minority votes, prompting him to describe the AIMIM chief and the BJP as “twin brothers”.
The exchange comes amid political preparations for the 2027 Assembly elections in Uttar Pradesh, with parties sharpening their positions and trading allegations ahead of the electoral contest.
Addressing a gathering in Uttar Pradesh’s Rampur, Owaisi had declared that he would “never make a Nehru, a Gandhi, or a Yadav” his leader. He also stressed the need to provide greater opportunities to young people from the Muslim community.
“Muslim youth have as much potential as people from other communities… However, they are not given a platform,” Owaisi had said, adding that the AIMIM would provide them with opportunities to move forward.
Responding to the AIMIM chief’s remarks, Congress MP Tiwari accused him of working to divide opposition votes in favour of the BJP.
Speaking to media, Tiwari said, “What standing does Owaisi have to even suggest someone like a Gandhi or a Nehru? His sole function, whether intentional or otherwise, is to divide the minority vote at the behest of the BJP. I can say with full confidence that this individual works for the BJP, as evidenced by election outcomes.”
Tiwari further cited electoral results in Maharashtra and Bihar to support his allegations, claiming that the AIMIM’s electoral performance had helped the BJP and its allies by splitting votes that could otherwise have benefited other candidates.
“In Maharashtra, while his party won four seats, it also caused other candidates to lose in 22 constituencies by splitting the vote, ultimately paving the way for a BJP-led government. He did something similar in Bihar … The results clearly show that he operates as an agent for the BJP. Owaisi and the BJP are twin brothers,” he added.
This comes as political parties begin gearing up for the 2027 Uttar Pradesh Assembly elections.
Tiwari also commented on the controversy surrounding the Special Intensive Revision (SIR) of electoral rolls being conducted by the Election Commission of India (ECI).
He argued that protecting citizens’ voting rights was essential and called for a change in government through the democratic process.
“The government in the country must be changed. The nation’s economic situation and foreign policy have both failed. The public wants relief from inflation and unemployment, and a change in government is essential to safeguard the right to vote. We want to change the government democratically through elections, and for that right to vote must be safeguarded,” Tiwari said.
