INSAT-3DS Satellite Embarks on its Journey to SDSC-SHAR Launch Port.

On January 25, 2024, the INSAT-3DS satellite, a dedicated meteorological endeavor by the Indian Space Research Organisation (ISRO), was ceremoniously flagged off to the Satish Dhawan Space Centre (SDSC-SHAR) launch port. This satellite marks a pivotal stride in providing seamless services, ensuring continuity from the existing INSAT-3D and 3DR satellites while significantly amplifying the capabilities of the INSAT system.

The INSAT-3DS satellite, a user-funded initiative in collaboration with the Ministry of Earth Science (MoES), has undergone meticulous Satellite Assembly, Integration & Testing activities at the U R Rao Satellite Centre in Bengaluru. The Pre-Shipment Review (PSR) on January 25, 2024, witnessed active participation from members of the user community, marking a crucial milestone in the satellite's journey.

Configured around ISRO's well-established I-2k bus platform and boasting a Lift-Off Mass of 2275 kg, the satellite is a testament to the substantial contributions made by Indian industries in its fabrication. Engineered for advanced meteorological observations, the INSAT-3DS satellite aims to monitor land and ocean surfaces for weather forecasting and disaster warnings. Its state-of-the-art payloads include a 6-channel Imager, a 19-channel Sounder for meteorology, as well as communication payloads such as the Data Relay Transponder (DRT) and the Satellite-Aided Search and Rescue (SAS&R) transponder.

The Data Relay Transponder (DRT) plays a pivotal role in enhancing weather forecasting capabilities by receiving meteorological, hydrological, and oceanographic data from Automatic Data Collection Platforms (ADCP) and Automatic Weather Stations (AWS). Meanwhile, the Satellite-Aided Search and Rescue (SAS&R) transponder facilitates the relay of distress signals and alerts, contributing to search and rescue services with global coverage. As INSAT-3DS sets out for its launch onboard GSLV F14, it heralds a new era in meteorological observation and disaster management.

NASA/ESA Hubble Space Telescope Reveals New Details of the Orion Nebula’s Star Formation.

This NASA/ESA Hubble Space Telescope image captures the Orion Nebula (Messier 42, M42), the nearest star-forming region to Earth, located about 1,500 light-years away. A captivating new image captured by the NASA/ESA Hubble Space Telescope offers an extraordinary look into the Orion Nebula, the nearest massive star-forming region to Earth. Located just 1,500 light-years away, this nebula is visible to the naked eye below the three stars forming Orion's "belt." The region is home to hundreds of newborn stars, including two protostars featured in the image: HOPS 150 and HOPS 153. Named after the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory, the protostars HOPS 150 and HOPS 153 provide key insights into the early stages of star formation. HOPS 150, visible in the upper-right corner of the image, is a binary star system, with two young stars orbiting one another. These protostars are surrounded by small dusty disks, where material from th...

New Method Detects Small Asteroids in Main Belt, Offering Insight for Planetary Defense.

An international team of physicists, led by MIT researchers, has developed a groundbreaking method to detect small asteroids, as small as 10 meters in diameter, within the main asteroid belt. These space rocks, ranging from the size of a bus to several stadiums wide, were previously undetectable using traditional methods. The team's discovery, detailed in a paper published in Nature, could significantly improve tracking of potential asteroid impactors, aiding planetary defense efforts. The main asteroid belt, located between Mars and Jupiter, is home to millions of asteroids, but until now, scientists could only detect objects roughly a kilometer in diameter. The new detection technique, which utilizes the "shift and stack" method, is able to identify much smaller asteroids, even those far from Earth, enabling more precise orbital tracking. This breakthrough is crucial for planetary defense, allowing scientists to spot near-Earth objects that may pose a threat in the fu...

XSPECT Payload Successfully Validates Performance through Cas A Observation.

The XSPECT instrument captures a detailed spectrum of the supernova remnant Cassiopeia A (Cas A), encompassing both the Galactic Cosmic Ray (GCR) background and the Cosmic X-ray Background (CXB). The flux observed above 8 keV predominantly results from the combined contributions of CXB and GCR. The presented spectrum, depicted in the figure, is derived from a cumulative integration time of 20 ksec, collected across multiple orbits, providing valuable insights into the X-ray emissions associated with Cas A. XPoSat, India's inaugural X-ray polarimetric mission, has achieved a significant as the XSPECT instrument captures its initial observations from the Cassiopeia A (Cas A) supernova remnant. Launched on January 1, 2024, XPoSat is equipped with two co-aligned instruments, namely the POLarimeter Instrument in X-rays (POLIX) and X-ray SPECtroscopy and Timing (XSPECT). This mission is designed to unravel the mysteries of cosmic X-ray sources. While POLIX focuses on examining X-ray po...
