ISRO to launch earth observation satellite on Sunday, its 101st mission
ISRO will launch an earth observation satellite EOS-09 on-board its workhorse PSLV on Sunday (May 18) at 05:59 am from the country's only spaceport at Sriharikota, a remote sensing satellite mission. This comes four months after the space agency's 100th launch failed to put the navigation satellite NVS-02 in the intended orbit.
The EOS-09 satellite, with a mission life of five years, will have a Synthetic Aperture Radar (SAR) payload, capable of providing images of the earth in all weather conditions. The satellite, which is a repeat of EOS-04 launched in 2022, has been designed to improve the frequency of observations.
This is the second PSLV — after last December's launch of Spadex mission — where the vehicle was assembled in ISRO's new Payload Integration Facility (PIF). This facility allows the integration of the launch vehicle in a separate facility, before being moved to the mobile launch tower for the lift-off, leaving the launch pad free for other launches. The facility was set up to free up the first-launch pad for an increased number of launches.
Sunday's launch will see the satellite being injected into orbit just over 17 minutes after the lift-off. The satellite will be placed in a Sun-synchronous polar orbit, which means the satellite would pass over a given place at the same time every day.
Importantly, the satellite will carry fuel that will be reserved for de-orbiting it after the end of its mission-life. The orbit of the satellite will be lowered in a manner that it will enter the earth's atmosphere and burn up within two years, making it a debris-free mission. In fact, the fuel on-board the fourth stage of the launch vehicle will also be removed in line with international guidelines. It is also recommended that stored fuel be removed from spacecrafts or upper stages of launch vehicles to ensure that there are no accidents that break up the satellite in space and create more debris.

After bad weather, liquid oxygen leak stalls Shubhanshu Shukla-piloted Axiom-4 lift-off
CAPE CANAVERAL (FLORIDA): Group Captain Shubhanshu Shukla's lift-off to Indian space history will have to wait. As D-Day dawned in India, Elon Musk-owned SpaceX announced that the Axiom-4 launch had been indefinitely deferred, citing a LOX (liquid oxygen) leak in the Falcon-9 rocket that engineers were unable to troubleshoot immediately. Tired of too many ads? go ad free now Axiom-4 was to start its journey to the International Space Station from Kennedy Space Center's Launch Complex-39A at 5.30pm IST on Wednesday. The originally scheduled Tuesday launch was postponed by a day due to adverse weather. "Standing down from tomorrow's Falcon-9 launch of Ax-4 to the International Space Station to allow additional time for SpaceX teams to repair the LOX leak identified during post-static fire booster inspections. Once complete - and pending range availability - we will share a new launch (date)," Space X said in a statement released at 8.45pm Eastern Time Tuesday (6.15am IST, Wednesday). Hours earlier, it had shared a video of Falcon-9 and Dragon at sunrise and said the weather was 85% favourable for lift-off, with teams continuing to monitor highwinds in the ascent corridor. Installing purge to plug leak: SpaceX Hours earlier, it had shared a video of Falcon-9 and Dragon at sunrise and said the weather was 85% favourable for lift-off, with teams continuing to monitor highwinds in the ascent corridor. Isro chairman V Narayanan said, "... Based on the discussion on this topic by the Isro team with the experts of Axiom and SpaceX it has been decided to correct the leak and carry out necessary validation tests before clearing for the launch." TOI had reported on June 10 that SpaceX had unresolved technical snags that were detected during a 10-second pre-static test fire. On Saturday, Dragon and Falcon "went vertical" on the launch pad ahead of a dry rehearsal. Tired of too many ads? go ad free now On Sunday (June 8), SpaceX performed the static fire and began analysing data. "We discovered a few things during the static fire that we had to go take a look at. We found a LOX leak that we previously had seen on this booster during its entry on its last mission and discovered that we had not fully repaired the booster during refurbishment, or we actually didn't find a leak and didn't get it corrected," William Gerstenmaier, SpaceX vice-president of build and flight reliability, said late Monday. Stating that teams were trying to fix the issue, he added, "We should get that completed today, and we will have that back in configuration, and we are installing a purge that will essentially mitigate the leak." SpaceX also identified a thrust vector control issue with engine 5. The affected components have since been replaced. Gerstenmaier stressed the company's continued focus on safety and precision, noting that "space flight is really hard, and we are learning every day".

Mysuru's DFRL understands gravity of astronauts' food cravings
Mysuru: The launch of the Axiom-4 mission carrying Indian astronaut Shubhanshu Shukla and three others to the International Space Station (ISS) may have been postponed. .But Mysuru-based Defence Food Research Laboratory (DFRL), under DRDO, has prepared a variety of food items that were to have been carried as part of the Indian Space Research Organisation (Isro) and the Defence Research and Development Organisation (DRDO) have developed an Indian menu for space after years of with scientific instruments and personal mementoes, Shubhanshu would have carried Mysuru-made food to the ISS in the Axiom-4 mission that has now been put off. .SpaceX's Axiom 4 mission postponed again, India's Shubhanshu Shukla's maiden journey to ISS officer Madhukar confirmed to DH that the astronaut was to carry a few Indian foods for the mission, including mango nectar (aam ras), carrot halwa (gajar ka halwa), moong dal halwa and a few rice human spaceflight programme director had disclosed this in a meeting held recently in Bengaluru..'As per the memorandum of understanding (MoU) between Isro and DRDO, we are not allowed to give out more details,' Madhukar said..'We are excited that the food products prepared here will be tasted by astronauts of the ISS mission. It is an effort to make the Indian astronaut's space mission memorable,' he cookies and candies are packed for space trips. NASA's space food systems laboratory produces freeze-dried this time the Indian astronaut will have Indian food on DFRL has developed a range of ready-to-eat and semi-hydrated Indian dishes for the mission, tailored for zero gravity. This includes parathas, vegetable biryani, rice and dal, sambar, rajma, khichdi and food has been designed in such a way that it is lightweight, low-volume and easy-to-consume wholesome food. The astronaut just has to add water to the items and warm it before eating it in tickled Rakesh Sharma's taste buds DFRL was established in Mysuru in 1961 to cater to the needs of the Indian Army, Navy, Air Force, and paramilitary forces.

Axiom-4 launch: Crew safety paramount, Isro insisted in review meets
CAPE CANAVERAL (FLORIDA): Hours after SpaceX revealed late Monday that it had detected multiple snags in the Falcon-9 rocket that was to launch the Axiom-4 (Ax-4) crew aboard the Dragon spacecraft, a series of meetings unfolded Tuesday and in all of them, Isro asserted that crew safety was paramount. Group Captain Shubhanshu Shukla is part of the Ax-4 crew and is set to become only the second Indian to go to space. As part of the launch preparation, all nine engines of the first stage were to be tested together. During one of those tests, it was found that a control actuator had a glitch, and during static test fire, a liquid oxygen (LOX) leak was detected. Once this information came out on Monday, Isro was part of a meeting with all the stakeholders, where it strongly articulated its concerns about astronaut safety and wanted detailed discussions before greenlighting the launch. "That Isro team was led by chairman V Narayanan helped, given his experience, especially with cryogenic propulsion systems. After all, he helped build it for India. Isro had requested that all issues with the rocket needed to be 'resolved' before they went ahead with the launch," a source said. When contacted, Narayanan told TOI: "All I can say at this juncture is that for India and Isro, the safety of our astronaut and crew is paramount. Mission partners have decided to correct the leak and carry out necessary validation tests before clearing for the launch." When SpaceX vice-president of build and flight reliability, William Gerstenmaier, first revealed the information about the leak during a mission readiness review late on Monday, the issue was not categorised as something concerning. He said it would be resolved and the rocket would be ready for launch. However, after subsequent meetings between all partners involved in the mission, SpaceX and the other partners decided to scrub the launch, seeking "additional time for teams to repair the LOX leak.
