Axiom-4 mission to now launch on June 22
Taking to 'X', ISRO announced the new date after Indian scientists held discussions with their counterparts from Poland and Hungary.
These two countries have sent an astronaut each on the 14-day manned mission to the ISS, along with India's Gaganyatri Group Captain Shubhanshu Shukla and former NASA astronaut, who is the mission commander, Peggy Whitson. Members from Axiom Space and NASA were also part of the discussions held to address the delays and parameters.
'Based on the readiness status of the SpaceX Falcon-9 launch vehicle, the Dragon spacecraft, repairs in the Zvezda module of the space station, ascent corridor weather conditions, and the health and preparedness of the crew in quarantine, Axiom Space has informed that the next probable launch date is June 22, 2025,' ISRO said. Earlier on June 14, ISRO had announced that the mission would launch on June 19, 2025. But later the same day, it was withdrawn and ISRO said the next launch date would soon be announced.
The launch was initially targeted for May 29, but deferred to June 8, 2025, because of the observations in the electrical harness in the Crew Dragon Module. The launch was then postponed to June 9 because of the delay in the preparedness of the Falcon-9 rocket. The mission was then postponed to June 10 due to inclement weather at NASA's Kennedy Space Center in Florida from where the launch was to take place.
Also, during inspections and hot fire tests that were conducted on June 8, the team had observed oxygen leak in the engine bay, besides anomalies in one of the engine actuators. The launch was then rescheduled to June 11, anticipating the issues to be addressed.
On June 11, NASA and ISRO flagged their concerns to Russian space agency Roscosmos to evaluate the new pressure signature in the Zvezda Service Module on the ISS due to the air leak. ISRO had recommended to Axiom Space, NASA and SpaceX to carry out in-situ repairs and conduct a low temperature leak test to validate the performance of system.

Students from Amity Group of Schools Represent India at NASA's Kennedy Space Centre for Global Space Design Challenge
Students from Amity International School, Sector-46, Gurugram, Amity International School, Pushp Vihar, and Amity International School, Noida all part of the Amity Group of Schools – proudly represented India at the prestigious International Space Settlement Design Competition (ISSDC) held at NASA's Kennedy Space Centre, Florida, USA. Students from Amity Group of Schools proudly represented India at the International Space Settlement Design Competition, Kennedy Space Centre, USA The four-day ISSDC is a high-intensity industry simulation where global student teams design futuristic human settlements in space. This year's challenge involved creating a floating settlement in Venus's atmosphere for the extraction, refining, and export of metals and atmospheric gases. Each 'company' comprised about 64 students from multiple countries, working collaboratively across departments such as Structures, Critical Infrastructure, Human Factors, Mission Systems, and Business Planning. The Amity delegation joined Flectel Constructors, collaborating with peers from the United Kingdom, China, Mexico, Romania, Italy, and other Indian schools. Over a rigorous 40-hour marathon, the teams conceptualized and designed a detailed settlement proposal, which was presented to a panel of international experts through a 30-minute pitch and Q&A session. Their final design, titled Ariadnav, showcased creativity, technical expertise, and collaboration under high-pressure conditions. Dr. (Mrs.) Amita Chauhan, Chairperson, Amity Group of Schools, congratulated the students, saying, 'This milestone makes us immensely proud, not only for the achievement but for the courage, creativity, and collaborative spirit our students have demonstrated on a global platform. Their work at NASA's Kennedy Space Centre truly reflects the Amity ethos – nurturing leaders who think beyond boundaries, embrace challenges, and innovate for a better future.' This participation highlights Amity's commitment to STEM excellence and inspires the next generation of learners to dream bigger – reaching not just for the stars, but beyond.

Ax-4 mission with leakage would have been catastrophic, our scientists detected issue: ISRO chief
Hyderabad, Aug 19 (PTI) ISRO scientists identified a crack in the main feed line of the rocket that carried India's Subhanshu Shukla and three other astronauts to the ISS, prompting a rescheduled launch, and had the mission continued with the issue it would have been a "catastrophic failure," the agency chief V Narayanan said here on Tuesday. The crack forced the Axiom-4 mission (Ax-4) to be postponed from June 11 to 25 of the same month, he recalled. Delivering the Convocation Address of Osmania University here, Narayanan, narrating the sequence of events prior to Shukla's space voyage, said the ISRO team, camping at Kennedy Space Centre in the US, came to know about the flaw detected in the rocket on June 10, forcing the Indian scientists to demand a thorough probe into the issue. "There were 14 questions asked and none of the questions were answered satisfactorily, including where the leak was. It was not identified. We demanded the entire correction, because we were very clear. Because I have been working in that area for 40 years, I know what is the difficulty if a rocket takes off with a leak," Narayanan, also the Secretary, Department of Space, added. Afterwards, based on the Indian Government's demand, the Indian team had put up a note and the entire leakage was corrected. Later, the first launch (on June 11) was called off after the Indian scientists inspected and found a crack in the main feed line, he further said. "If the rocket would have taken off (with the leak), it would have been a catastrophic failure. Based on the insistence of Indians, the Indian education system, the training of ISRO, the rocket was corrected. Today we have accomplished a safe mission, not only Subhanshu Sjukla, along with him three more international astronauts," he said. Shukla returned to India early Sunday after his historic visit to the International Space Station (ISS). He was part of the Axiom-4 private space mission that lifted off from Florida on June 25 and docked at the ISS on June 26. He returned to Earth on July 15, along with three other astronauts- Peggy Whitson (US), Slawosz Uznanski-Wisniewski (Poland), and Tibor Kapu (Hungary). Shukla conducted over 60 experiments and 20 outreach sessions during the 18-day mission.

India Needs 40-50 Astronauts For Upcoming Space Missions: PM Modi
New Delhi: Prime Minister Narendra Modi said India needs to build a pool of 40-50 astronauts ready to lead future space missions as he interacted with Shubhanshu Shukla, who is back after spending 20 days in space. Mr Shukla, who became the first Indian to travel to the International Space Station (ISS) as part of the Axiom-4 commercial mission, told the prime minister that there was tremendous interest across the world about India's Gaganyaan mission Mr Shukla met Modi on Monday evening and shared his experiences of the time spent at the ISS, adjusting to micro-gravity conditions, and the experiments he carried out on the orbital lab. The video of the interaction was released on Tuesday. "There is a need to have a pool of 40-50 astronauts ready for India's future missions," Modi said, adding that Mr Shukla's space travel was the first step towards future missions. PM Modi said until now, very few children may have considered becoming astronauts, but Shukla's journey will instill greater belief and generate interest in the sector. The prime minister said India now has two major missions ahead - Bhartiya Antariskh Station and Gaganyaan, and Shukla's experience would be of great value in these endeavours Shukla said the two missions presented a major opportunity for the country and the sustained commitment of the government to the space sector, despite setbacks such as the Chandrayaan-II mission was laudable. He said the government's continued support to the space program with consistent budgeting led to the success of Chandrayaan-3. Mr Shukla said such support, even after failures, is being seen globally as a reflection of India's capability and positioning in the space domain. "India can acquire a leadership role and that a space station led by Bharat, with participation from other nations, would be a powerful tool," Mr Shukla said. Mr Shukla told the prime minister that India's Gaganyaan project was generating great interest around the world. "My crew mates even requested signed notes, expressing their desire to be invited to the launch and to travel aboard India's spacecraft," Mr Shukla said. India plans to undertake its first human spaceflight in 2027 and build its own space station by 2035. India also has plans to land its own astronaut on the moon by 2040.
