ISRO reflects a successful 2024
Chennai, May 31 (UNI) As the Indian Space Research Organisation (ISRO) is gearing up for mega launches including Chandrayaan, Gaganyaan and Indo-US Nissar Mission, besides sedning country's first Astronaut to International Space Station (ISS) on board Axiom-4 mission, the Space Agency looked back with pride its ahievements made in 2024. In an update on its website, ISRO said there were five launches from the spaceport of Sriharikota that proved successful that included precise injection of eight Indian spacecrafts, one foreign satellite and six rocket bodies, including POEM 3 and 4. They included PSLV-C58/XPoSat, PSLV-C59/PROBA-3, PSLV-C60/SPADEX docking experimental mission, GSLV-F14/INSAT-3DS, and SSLV-D3/EOS-08 mission, all of them successfullyinjected the payloads in their designated orbits. ISRO's GSAT-20 was launched by Falcon-9 Block 5 of SpaceX from Cape Canaveral. TSAT-1A was also launched by Falcon-9. "Consequently, a total of 8 Indian satellites, 1 foreign satellite, and 6 rocket bodies (including POEM-3 and POEM-4) were placed in their intended orbits", It said reflecting back on its achievements of 2024. It said a total of 136 Indian spacecraft, including those from private operators/academic institutions, were launched in Earth-orbit till December 31, 2024. As of that date, the number of operational satellites owned by the Indian government is 22 in LEO (Low Earth Orbit) and 31 in GEO (Geo-synchronous Earth Orbit). In addition, two Indian deep space missions, namely, Chandrayaan-2 Orbiter (CH2O) and Aditya-L1 at Sun-Earth Lagrange's point were also active. The propulsion module of Chandrayaan-3 spacecraft continued to operate in a high Earth orbit (more than 1 lakh km away) after being relocated from its lunar orbit since November 2023. ISRO Chairman Dr. V. Narayanan, releasing the Indian Space Situational Assessment Report (ISSAR) for 2024 compiled by ISRO System for Safe and Sustainable Space Operations Management (IS4OM), said the upper stage of PSLV-C3 underwent an accidental break-up in 2001 and generated 371 debris. While most of these fragments have re-entered the atmosphere, 41 PSLV-C3 debris were still in orbit by the end of 2024. On Atmospheric re-entry, it said among the intact Indian upper stages, 34 rocket bodies re-entered the Earth's atmosphere till 2024 end, and five of such re-entries took place in 2024. All LVM3 rocket bodies have decayed, only the one from LVM3 M2 OneWeb India- mission remain in orbit. Among GSLV rocket bodies, only GSLV-F12 and GSLV-F14 rocket bodies are in orbit. A total of 31 Indian satellites have re-entered the atmosphere till the end of 2024. In the year 2024 alone, 9 Indian satellites re-entered the atmosphere. Among them was Cartosat-2 which re-entered the atmosphere on February 14, 2024, the first-ever LEO satellite of ISRO to be de-orbited at end-of-life to reduce its post-mission orbital life from more than 30 to less than 4 years.

Unique digital address for every home in India
NEW DELHI: After 53 years since the Department of Posts adopted the IN CODE system, a path-breaking digital initiative has been launched by the department with an aim to further reduce emergency response time and ensure better citizen-centric delivery of public and private services. The Department of Posts has recently launched a digital addressing system based on geographical data. This marks a major upgrade over the present pin code system which is area-specific, as it would be unique for each residence or office. 'The National Addressing Grid or Digital Postal Index Number (DIGIPIN) will speed up service delivery and emergency response,' said a senior official in the department. It has been developed in collaboration with the ISRO (Indian Space Research Organisation), Indian Institute of Technology, Hyderabad and NRSC (National Remote Sensing Centre). The DIGIPIN is a 12-digit alphanumeric code. 'In a nutshell, it is a democratisation of the address system with each individual having a unique one. This is an open-source, geo-coded, grid-based digital address system,' the official said, adding, 'We are in the initial stages. As it progresses and becomes popular in future, one can just provide their name and house number with the DIGIPIN and everything could be delivered smoothly.' The new address system uses the latitude and longitude coordinates to fetch a unique DIGIPIN of a certain place and simplifies location mapping, the official added. It was in 1972 that the postal department adopted the PIN CODE system, which serves as the backbone of the Indian postal service. The novel digital initiative marks a modernisation of the address system.

How does Isro save satellites from collision?
The Indian Space Research Organisation (Isro) saved its satellites from collision 11 times in 2024 by performing collision avoidance manoeuvres. read more India saved its satellites from collision 11 times in 2024, according to Isro's Indian Space Situational Assessment Report (ISSAR) report. The Indian Space Research Organisation (Isro) in the report said that it saved six satellites in the low-Earth orbit (LEO) and four in the geostationary orbit (GEO) from collision. The Isro also said that it prevented the Chandrayaan-2 orbiter from a planetary collision. The Isro said that an orbit maintenance manoeuvre was originally scheduled for Chandrayaan-2 on November 26, 2024, but it was advanced to Nov. 11 to mitigate conjunctions with Nasa's Lunar Reconnaissance Orbiter (LRO), which were predicted to occur on Nov. 15-16. STORY CONTINUES BELOW THIS AD The Isro prevents such collisions by performing collision avoidance manoeuvres (CAM). These are planned changes in a spacecraft or a satellite's trajectory in space to avoid running into some other space object, which can be a body in the space, satellites, or debris from other satellites. The Isro performs such manoeuvres after conducting Space Situational Awareness (SSA) assessments to see whether an object in the space is going to be in the close vicinity of a spacecraft or a satellite. Such objects can include space debris, natural objects like asteroids and meteoroids, and energy and particle flux. ALSO READ: From a slow start to a concrete policy, how India has shaped space research with hits and misses Isro's System for Safe and Sustainable Operations Management (IS4OM) functions as the nodal entity for all space sustainability efforts, including SSA assessments and to improve compliance with internationally-recognised guidelines on the long-term sustainability of outer space activities. Isro in the report said that it conducts analyses to predict close approaches by other space objects to Indian space assets. In case of any critical close approach, CAMs are carried out to rule out or minimise the collision risk. Last year, the Isro said that the Combatant Space Operations Center of the US Space Command had issued more than 53,000 alerts Isro's Earth-orbiting satellites. These alerts were analysed using more accurate orbital data from flight dynamics and 11 collision avoidance manoeuvres were conducted — as mentioned above. STORY CONTINUES BELOW THIS AD The Isro released the following graph to show the CAMs conducted in recent years: Cumulative number of collision avoidance manoeuvres (CAMs) performed for Earth-orbiting satellites of Isro till 2024. (Photo: Isro) The number of CAMs was less in 2024 compared to the previous year because improved close approach analysis methodology with larger conjunction screening volume and usage of more accurate ephemerides helped to meet collision avoidance requirements by adjusting orbit maintenance manoeuvres on several occasions and avoiding exclusive CAMs, according to Isro. Last year, the Isro said, all manoeuvre plans, including those of the CAMs, were subjected to close approach risk analysis to rule out any potential close approach with other neighbouring space objects imminently after the manoeuvres. In doing so, the report said that 89 manoeuvre plans were revised to avoid post-manoeuvre close approaches with other space objects for LEO satellites and on two occasions manoeuvre plans were revised such for GEO satellites.

ISRO averts 10 collisions in space, backs requirement of Space Traffic Management system
The Indian Space Research Organisation (ISRO) in 2024 successfully averted 10 potential collisions involving its satellites. As per the Indian Space Situational Assessment Report (ISSAR) released by the space agency, collision avoidance manoeuvres (CAM) were carried out to avoid damages. The space agency also flagged the increase in space activity across the globe and highlighted the need for an active Space Traffic Management (STM) system. 'The sheer number of close approach alerts indicates the alarmingly rising congestion in space, especially low-Earth orbit,' ISRO said in its report, adding that with the easier access to space through rideshare, coupled with technological advancements, the future space traffic is not likely to show any signs of slowing down. The agency added that spaceflight safety in the future is expected to involve more intensive coordination and cooperation between various spacefaring entities. 'It is desirable that a suitable collaborative framework evolves for meeting STM requirements,' ISRO said. The space agency received more than 53000 alerts by the Combined Space Operations Center (CSpOC), the US–led multinational space operations center for its satellites, which were analysed using data from flight dynamics resulting in 10 anomalies. ISRO carried out six critical manoeuvres in LEO and four in GEO. For Chandrayaan-2 an orbit maintenance manoeuvre was also conducted to mitigate conjunctions with Lunar Reconnaissance Orbiter, a NASA mission launched in 2009. Currently, India has 22 satellites in LEO (Low Earth Orbit) and 31 in GEO (Geo-synchronous Earth Orbit), which are important to protect. In 2024 India undertook five launches from Sriharikota and all of them were successfully placed in their intended orbits. ISRO said the number of CAMs was lesser in 2024 compared to the previous year. 'This is because improved close approach analysis methodology with larger conjunction screening volume and usage of more accurate ephemerides helped to meet collision avoidance requirements by adjusting orbit maintenance manoeuvres on several occasions and avoiding exclusive CAMs.' The space agency said post the corrections, 89 manoeuvre plans were revised to avoid post-manoeuvre close approaches with other space objects for LEO satellites.
