‘Permanent Pictorial Cancellations will help to attract tourists'
Mysuru: Senior superintendent of post offices (SSPO) for Mysuru postal division, G Harish, on Saturday said that Permanent Pictorial Cancellations released by the postal department not only highlight prominent tourist destinations and other major landmarks of the cities, but also help to attract tourists and promote tourism in the region. He was speaking after releasing the Permanent Pictorial Cancellation of the Silver Jubilee Clock Tower, one of the major landmarks of the heritage city of Mysuru, at a function held at his office. The Permanent Pictorial Cancellation of the Silver Jubilee Clock Tower, brought out by the department, highlights the significance of this major landmark to tourists across the world, he said. Speaking on the same occasion, deputy superintendent of post offices for Mysuru postal division GL Navin said that his department has also planned to bring out special postcards about the Silver Jubilee Clock Tower on account of its 100 years of establishment celebrations in the next two years.

Why did EOS-09 satellite mission fail? ISRO reveals initial observation
After taking off at the scheduled time of 5.59 am on Sunday, the 101st launch of the Indian Space Research Organisation (ISRO) failed mid-flight during its third stage, just minutes after the launch. ISRO's otherwise reliable PSLV C61 rocket launched from Satish Dhawan Space Centre in Sriharikota with EOS 09, an earth observation satellite, onboard. The mission was to carry the Earth observation satellite into a Sun Synchronous Polar Orbit (SSPO). However, the launch suffered a technical glitch during the third stage of PSLV's flight and failed.

Due to an observation in the 3rd stage, the mission could not be accomplished,' said the space agency. According to ISRO's Chairman V Narayanan, the Polar Satellite Launch Vehicle is a 4-stage rocket, and the first two stages were normal. However, during the third stage, there was a 'fall in the chamber pressure of the motor case' which caused the mission failure. Also read: EOS-09 mission: What ISRO said on the failed satellite launch "Today, we targeted the 101st launch from Sriharikota, the PSLVC61 EOS-09 mission. The PSLV is a four-stage vehicle, and up to the second stage, the performance was normal. The third stage motor started perfectly, but during the functioning of the third stage, we are seeing an observation," Narayanan said. "...and the motor pressure--there was a fall in the chamber pressure of the motor case, and the mission could not be accomplished. We are studying the entire performance, we shall come back at the earliest," he added, according to a PTI report. EOS-09 is a repeat satellite of EOS-04, designed with the mission objective to ensure remote sensing data for the user community engaged in operational applications and to improve the frequency of observation, according to ISRO. The mission was ISRO's 101 launch. Had the mission been successful, the Orbit Change Thrusters (OCT) would have been used to reduce the altitude of the PS4 stage, followed by passivation to limit its orbital life after the deployment of EOS-09. The mission carried a Synthetic Aperture Radar (SAR) payload capable of providing images for various earth observation applications under all-weather conditions.

Isro's 101st mission fails as PSLV-C61 suffers third-stage anomaly
Isro was unable to complete the launch of its Earth observation satellite EOS-09 aboard PSLV-C61 on Sunday due to an anomaly in the third stage of the four-stage rocket, investigation is underway Vrinda Goel New Delhi India's latest Earth observation satellite mission faced a setback on Sunday morning. The Indian Space Research Organisation (Isro) launched its 101st mission, carrying the Earth Observation Satellite, named as EOS-09, aboard the Polar Satellite Launch Vehicle (PSLV-C61) rocket from the Satish Dhawan Space Centre, Sriharikota, at 5:59 am. It was to be put in a Sun Synchronous Polar Orbit (SSPO). However, Isro later confirmed that the mission could not be completed successfully. Early launch smooth, but satellite fails to reach orbit Isro was unable to complete the launch due to an anomaly in the rocket's third stage. The space agency, in a post on X, said, "Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be accomplished." #WATCH | Sriharikota, Andhra Pradesh | ISRO Chief V Narayanan says, "Today we attempted a launch of PSLV-C61 vehicle.

The third stage motor ignited successfully, but an issue arose during its operation, preventing the mission from succeeding.' He added, 'We will return after conducting a thorough analysis.' What is the EOS-09 mission? EOS-09 is an advanced Earth observation satellite equipped with C-band synthetic aperture radar technology, This high-tech Earth observation satellite isn't bothered by clouds, darkness, or bad weather, it snaps razor-sharp images of the planet's surface 24/7. The all-weather, all-hours capability gives a major boost to India's surveillance, environmental monitoring, and disaster management efforts across the board. EOS-09 is a follow-up to EOS-04, launched in 2022, and was designed to provide continuous remote sensing data to support operational activities and enhance observation frequency. #WATCH | Indian Space Research Organisation (ISRO) launches PSLV-C61, which carries the EOS-09 (Earth Observation Satellite-09) into a SSPO orbit, from Sriharikota, Andhra Pradesh.

Post-deployment, the launch vehicle's PS4 stage was intended to use Orbit Change Thrusters (OCT) to lower its altitude before undergoing passivation, an industry-standard process to reduce orbital lifespan and ensure responsible space operations. Part of a satellite constellation 'EOS-09 is a crucial satellite within a constellation that monitors Earth and its changes. It supports areas like agriculture, forestry, disaster management, and strategic uses, especially in monitoring border regions,' Selvamurthy told ANI.

"Mission could not be accomplished": ISRO chief Narayanan on EOS-09 satellite launch
Sriharikota: The Indian Space Research Organisation (ISRO) observed technical problems during the 3rd stage of the launch of the EOS-09 satellite, due to which they could not complete the mission, the ISRO chief V Narayanan said while addressing the scientists after the launch on Sunday. "During the functioning of the third stage, we are seeing an observation and the mission could not be accomplished. After analysis, we shall come back," the ISRO chairman said. The ISRO also posted on X about the development. "Today 101st launch was attempted, PSLV-C61 performance was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be accomplished." The flight sequence of the PSLV-C-61 consists of various stages, starting from Ignition of PS1 and PSOM at the ground, to separation of various sections to finally the separation of the satellite from the rocket. According to the ISRO chief, the problem was detected at the third stage, which is a solid rocket motor which provides the upper stage with a high thrust after the atmospheric phase the launch. This stage has a maximum thrust of 240 Kilonewtons. This was ISRO's 101st launch, in which they launched the Earth Orbiting Satellite, also known as EOS-09, which was supposed to be put in a Sun Synchronous Polar Orbit (SSPO). The plan was for the EOS-09 satellite to be deployed as Orbit Change Thrusters (OCT) will be used to lower the altitude of the PS4 stage. This will be followed by passivation, a measure aimed at reducing the stage's orbital life and ensuring responsible space is designed to deliver continuous and reliable remote sensing data for use in various operational sectors. Notably, this launch was also aligned with promoting sustainability and carrying out responsible space operations, as the EOS-09 is equipped with deorbiting fuel for safely disposing it off after the mission. EOS-09 is an advanced Earth observation satellite equipped with C-band synthetic aperture radar technology. It can capture high-resolution images of the Earth's surface under all weather conditions, day or night. This capability enhances India's surveillance and management systems across multiple sectors.
