Contact with the lander-rover may have been lost, but expectations from the orbiter are still intact.

Signal was stopped from the Vikram lander just 2.1k.g before the landing,and for some time there was silence in the center of ISRO,
as the Vikram lander was seen up to 2.1 k,g altitude with normal performance.
Subsequently,communication from the Vikram lander to ground stations was lost.The data was analyzed by scientists,
but nothing came out, even though contact with the lander-rover has been lost, but expectations from the orbiter are still.

Vikram Lander kept contact with the lander for a distance of 2.1 km from the moon, but after that the contact broke, scientists could not contact the lander again.Siwan of ISRO ceo says that only after studying the data that has been received at the last time of landing, the cause of contact breakdown will be known.On this occasion, Prime Minister Modi, who was present at ISRO's headquarters in Bengaluru, took updates from scientists.When ISRO chief Sivan was giving updates to the PM, then fellow scientists patted him on the consolation.

The floor was very close, just two steps away, but the victory slipped away on the last occasion.But even though contact with the lander-rover has been lost, expectations from the orbiter still remain. Because the lander-rover was successfully separated from the orbiter on September 2, and the orbiter is still about 100 kilometers from the moon.Successfully circling the classroom.  ISRO is receiving signals and necessary data from it.

Last minute opening night for Chandrayaan 2At 1:38 pm there was a process of rough breaking, and its programming was done in Chandrayaan before then.
 Vikram Lander, which is exactly 30 km from the lunar surface at 1:40 am, started descending controllably; at 1:40 pm when Chandrayaan started landing on the lunar surface, its speed was 6 km per second, meaning 21600  Km per hour.Fine breaking began to slow the lander at 1:48 pm.And its process was already programmed in Chandrayaan.When Vikram Lander At 1:48 the fine breaking process started, the lander's distance from the moon was only 2.1k.g, and in the nightAt 1:51 am, the figures stopped getting from the lander, and thus Vikram Lander's journey ended.  But hope still remains.

 Journey from Earth to Moon was a risky one for Chandrayaan 2, Chandrayaan 2's journey to the moon was 47 days, Chandrayaan 2 took the orbiter lander-rover with him, ISRO's rocket GSLY-Mark 3 on 22 July 2019  The launch of Chandrayaan-2 was carried out by Chandrayaan-2 orbiting in different orbits of the Earth for 23 days, and then Chandrayaan-2 was sent to the Lunar Transfer Trajectory on 14 August 2019. Successfully entered Moon's orbit on 20 August 2019.  And after that, on 1 September 2019, Chand was brought to the nearest orbit.

 On 02 September 2019, Lander-Rover was separated from the orbiter.  By 4 September 2019, making changes to the class twice, the Lander-Rover was brought to the nearest orbit of the moon.

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

By Surendra Uikey
  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.

By Surendra Uikey
  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.

By Surendra Uikey
  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...
