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.

CBI court sentences firm partner to three years RI in Rs 4 crore bank fraud case

Chandigarh, June 5: A Special CBI Court in Mohali, Punjab, has convicted and sentenced Samir Dua, a partner of M/s G.D. Ispat Udyog, Mandi Gobindgarh, to three years of rigorous imprisonment (RI) along with a fine of Rs 15,000 in connection with a multi-crore bank fraud case, an official statement said on Friday.
The sentence was pronounced on June 4, following the conclusion of trial proceedings in the case investigated by the Central Bureau of Investigation (CBI).
According to the CBI, the case was registered against Dalip Dua and Samir Dua, partners of M/s G.D. Ispat Udyog, along with other accused, for allegedly entering into a criminal conspiracy to defraud Indian Overseas Bank’s Mandi Gobindgarh branch in Punjab.
The investigation revealed that the accused had fraudulently secured a cash credit limit of Rs 4 crore from the bank by submitting false and fabricated information and documents.
The loan facility was allegedly obtained through misrepresentation, causing a wrongful loss to the bank and corresponding unlawful gain to the accused, the agency said.
Following a detailed investigation, the CBI filed a charge sheet against the accused persons before the competent court. During the trial, the prosecution presented evidence establishing the fraudulent nature of the transactions and the conspiracy behind obtaining the credit facility.
After examining the evidence and hearing the arguments, the Special CBI Court found Samir Dua guilty and sentenced him to three years of rigorous imprisonment. The court also imposed a monetary penalty of Rs 15,000.
Proceedings against co-accused Dalip Dua were abated due to his death during the pendency of the case.
The conviction marks the culmination of the CBI’s investigation into the bank fraud, underscoring the agency’s efforts to prosecute financial crimes and hold those responsible for defrauding public sector banks accountable.

SIR will be used to create a permanent class of excluded Indians: Owaisi

Hyderabad, June 3: AIMIM president Asaduddin Owaisi on Wednesday said that Special Intensive Revision (SIR) of electoral rolls will be used to create a permanent class of excluded Indians.
He claimed that 6.5 crore names were deleted from the electoral rolls under SIR in 13 states and union territories.
The Hyderabad MP took to ‘X’ to slam the Centre for the proposal to constitute a committee to study the exclusions and build a permanent system for the identification, detention, and deportation of illegal immigrants.
“The Union Government first carried out a document-driven SIR that deleted nearly 6.5 crore names from electoral rolls across 13 States and UTs. Now it wants a committee to study those very exclusions and build a permanent system for the identification, detention, and deportation of illegal immigrants,” posted Owaisi.
“SIR will be used to create a permanent class of excluded Indians. The right to vote is the poor’s only weapon against the powerful. Without it, the government will do what it pleases with them. We are already seeing reports of people being denied the benefits of government schemes.”
“Under the law, a deletion under SIR does not mean that a person is not a citizen. Twenty-seven lakh people are still under adjudication, and many may apply afresh for enrolment as voters through Form 6. The ECI itself has provided no data on the number of people it excluded because they were foreigners. Available data show that most of those excluded by SIR are Muslims, women, the poor, and migrants,” wrote the MP.
“The government’s own data show that our demography and population have stabilised and that our TFR is 2.0. Why do we need this committee, then? So that there can be constant paranoia and fear directed against Muslims,” said the All India Majlis-e-Ittehadul Muslimeen (AIMIM) chief.
“This government loves making Indians waste their time on documentation. Sometimes it is KYC or SIR; sometimes it is uploading some document to some portal. But it cannot conduct a simple exam properly. Common people are scrutinised by the government, but the government cannot be scrutinised by us,” he added.
