Sriharikota (Andhra Pradesh) (PTI): ISRO on Monday successfully launched its maiden X-Ray Polarimeter Satellite that would offer several insights into celestial objects like black holes.

ISRO's ever reliable Polar Satellite Launch Vehicle (PSLV) in its C58 mission, placed the primary X-Ray Polarimeter satellite XPoSat into a 650 Km Low Earth Orbit as intended after lifting off at the pre-fixed time of 9.10 am from the first launch pad here.

As the 25-hour countdown concluded, the 44.4-metre tall rocket lifted off majestically with thunderous applause from spectators who had descended here in large numbers at this spaceport situated about 135 km east of Chennai.

The X-ray Polarimeter Satellite (XPoSat) is aimed to investigate the polarisation of intense X-ray sources in space.

According to ISRO, it is the first dedicated scientific satellite from the space agency to carry out research in space-based polarisation measurements of X-ray emission from celestial sources.

The X-Ray polarisation serves as a crucial diagnostic tool for examining the radiation mechanism and geometry of celestial sources.

The primary payload of XPoSat is POLIX (Polarimeter Instrument in X-Rays) which is designed to measure polarimetry parameters by Raman Research Institute and XSPECT (X-ray Spectroscopy and Timing) built by the U R Rao Satellite Centre, Bengaluru. The Mission life is about five years.

Patna (PTI): In a major expansion of the Cabinet of Bihar's first BJP-led government, JD(U) supremo Nitish Kumar's son Nishant Kumar and 31 others took oath as ministers on Thursday in the presence of Prime Minister Narendra Modi and Union Home Minister Amit Shah.

Altogether 32 leaders, drawn from all constituents of the five-party NDA in the state, were administered the oath of office by Governor Lt Gen (Retd) Syed Ata Hasnain at a grand ceremony that was also attended by Defence Minister Rajnath Singh and Union Health Minister J P Nadda and BJP president Nitin Nabin.

Prominent inductees included Nishant Kumar, the son of JD(U) president Nitish Kumar, who stepped down as chief minister last month to enter the Rajya Sabha.

The BJP, which is the single largest party in the 243-member assembly with 89 MLAs, has 15 ministers, who took oath on Thursday.

Most of the inductees were those who were part of the Nitish Kumar cabinet formed in November last year after the NDA stormed back to power in the assembly polls.

The JD(U) is represented by a total of 15 ministers, 13 of whom took the oath at the Gandhi Maidan on Thursday. Vijay Kumar Chaudhary and Bijendra Prasad Yadav had taken oath in April along with Samrat Choudhary and were designated as deputy chief ministers.

Sanjay Kumar Singh and Sanjay Kumar Paswan, both from the Lok Janshakti Party (Ram Vilas) headed by Union minister Chirag Paswan, are back as ministers, and so are Santosh Kumar Suman and Deepak Prakash, sons of Union minister Jitan Ram Manjhi of the Hindustani Awam Morcha and Upendra Kushwaha of the Rashtriya Lok Morcha, respectively.
