Axiom Launch To Send Shubhanshu Shukla To Space Deferred For Rocket "Repair"
In a post on X, SpaceX said the mission to the International Space Station (ISS) was deferred due to a technical glitch in its Falcon 9 rocket that is being used for the launch. The new date for the launch is yet to be decided.
"Standing down from tomorrow's Falcon 9 launch of Ax-4 to the @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," it posted on the microblogging site.
The LOx leak refers to an oxygen leak.

Group Captain Shukla will be the first Indian to fly to the ISS under the private astronaut mission that will launch aboard a SpaceX Crew Dragon capsule on a Falcon 9 rocket, from the Kennedy Space Centre in Florida. The mission is jointly being undertaken by Axiom Space Inc, the National Aeronautics and Space Administration (NASA) and Indian Space Research Organisation (ISRO).
According to ISRO, the oxygen leak was detected in the propulsion bay during a performance test.
"As part of launch vehicle preparation to validate the performance of booster stage of Falcon 9 launch vehicle, seven second of hot test was carried out on the launch pad. It is understood that LOX leakage was detected in the propulsion bay during the test. Based on the discussion on this topic by ISRO team with the experts of Axiom and SpaceX it has been decided to correct the leak and carry out necessary validation test before clearing for the launch. Hence the launch of Axiom 04 slated for 11th June 2025 for sending first Indian Gaganyatri to ISS is postponed," ISRO Chairman Dr V Narayanan said on X.

The mission was scheduled to take off on Tuesday but was kept on hold due to bad weather. The last time it was deferred was from June 8 to June 10 - again on grounds of adverse weather conditions.
Thirty-nine-year-old Shukla will be accompanied by Peggy Whitson, a former NASA astronaut and mission commander, Slawosz Uznanski-Wisniewski from Poland and Tibor Kapu from Hungary. Once docked, the astronauts are scheduled to spend up to 14 days aboard the orbiting laboratory, conducting a mission comprising science, outreach and commercial activities.
Group Captain Shukla's travel to space comes four decades after Rakesh Sharma's iconic spaceflight onboard Russia's Soyuz spacecraft in 1984. He will serve as the Mission Pilot.
A decorated test pilot with the IAF, Mr Shukla was shortlisted under ISRO's Human Spaceflight Program (HSP) and is among the top contenders for the Gaganyaan mission, India's first indigenous crewed orbital flight. His journey aboard the Axiom Mission 4 is expected to provide critical hands-on experience in spaceflight operations, launch protocols, microgravity adaptation, and emergency preparedness - all essential for India's crewed space ambitions.
The Group Captain will conduct seven experiments in the fields of agriculture, food and human biology when he travels to the ISS next month.

ISRO working on 40-storey tall rocket: ISRO Chief
ISRO Chairman V Narayanan on Tuesday said the space agency has been working on a rocket as high as a 40-storey building to place a 75,000 kg payload in low earth orbit. Delivering the convocation address of Osmania University in Hyderabad, Narayanan said this year, the space agency has lined up with projects such as NAVIC (Navigation with India Constellation system) satellite and the N1 rocket, besides placing a 6,500 kg communication satellite of the US into orbit using Indian rockets. He said by 2035, a 52-tonne mass space station is going to be built even as ISRO is working on the Venus Orbiter mission. 'Right now, we are working on a next generation launcher. You know, what is the capacity of the rocket? The first launcher, (Dr APJ) Abdul Kalam, which he built was a 17-tonne lift-off mass, capable of placing 35 kg in low earth orbit. Today, we are conceiving a rocket to place 75,000 kg in low earth orbit. The rocket is of 40-storey building height,' he said. 'ISRO has planned to launch Technology Demonstration Satellite (TDS) and GSAT-7R, an Indian military communication satellite, specifically designed for the Indian Navy to replace the existing GSAT-7 (Rukmini) satellite, this year among others,' he further said. Narayanan said right now, India has 55 satellites in orbit and the number is going to be increased to three times in another three to four years. Narrating the sequence of events prior to astronaut Subhashnu Shukla's successful journey to the International Space Station and return, he said the original project was scheduled for June 11. However, a day before a team-led by him identified a leakage in the rocket, it was postponed to June 25. 'And with that, if the rocket would have taken off, 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 Shubhanshu Shukla, but along with him three more international astronauts,' he said. Explaining the domestic space journey, Narayanan said today India is in a position to rub shoulders with advanced space-faring nations. According to him, as of now, India has the credit of launching over 4,000 rockets. India's first satellite Aryabhatta was launched in 1975 with the support of other countries, and from then on, as many as 133 satellites of various types, including a 6,000 kg high-throughput GSAT-11 satellite, which is right now, have been launched, he said. India has the best camera on the moon with 32-centimeter resolution and is the only country till today to have succeeded Mars orbiter mission in the first attempt while none of the developed countries could do so. 'ISRO is the first organisation and India is the first country which successfully placed 104 satellites using a single rocket in the first attempt. And we made history. And today, we have built the Aditya L1 satellite to study the sun,' Narayanan said. Not only studying the sun, but it has also brought 20 terabit data. India is one among four countries having the capability which has built the satellite for studying the sun, he added. At the convocation, Narayanan was presented with the honorary degree of Doctor of Science, recognising his pivotal contributions to India's space programme, by Telangana Governor Jishnu Dev Varma. Later, speaking to reporters on the sidelines of the event, Narayanan said Shubhanshu Shukla has successfully come back (after spending 20 days in space). His (Shubhanshu's) experience is going to feed India's Gaganyaan programme, he said. Asked about Prime Minister Narendra Modi suggesting that India needs to build a pool of 40-50 astronauts ready to lead future space missions, Narayanan said, 'In the future it will happen. Whatever the Prime Minister has said, it will happen'.

India will build a pool of 40-50 Astronauts
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. 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 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 Shukla's space travel was the first step towards future missions. Modi said until now, very few children may have considered becoming astronauts, but Shukla's journey will instil 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. 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," Shukla said. 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," 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.

Kairan Quazi's education and career: How a 16-year-old prodigy graduated early, left SpaceX, and is now joining Citadel Securities
Elon Musk 's youngest hire, Kairan Quazi, is trading rockets for trading algorithms. At just 16, the Bangladeshi-American prodigy has left SpaceX 's Starlink division after two years to join Citadel Securities in New York City as a developer. The move marks his entry into one of Wall Street's most competitive arenas, where engineering talent is increasingly being courted by finance giants vying with AI labs and Big Tech for the brightest minds. 'I felt ready to take on new challenges and expand my skill set into a different high-performance environment,' Quazi told Business Insider in an exclusive interview. But how did a teenager manage to leap from middle school to Wall Street in less than a decade? A childhood marked by acceleration Quazi's journey has been anything but conventional. Skipping from third grade directly to college at age nine, he enrolled at Las Positas College, where he graduated with highest honors in mathematics at just 11. By 14, he had already become the youngest graduate in Santa Clara University's 170-year history, completing a Bachelor of Science in Computer Science and Engineering cum laude, alongside graduate-level coursework in advanced algorithms, NLP, and data mining. During his undergraduate years, he combined academic rigor with teaching responsibilities, serving as a college tutor in calculus, statistics, and chemistry — an unusual role reversal for someone barely in his teens. From research labs to rocket science Even before completing his degree, Quazi built an impressive portfolio of research and industry experience. At age 10, he became the first undergraduate intern at Intel Labs' Human AI group, working on predictive speech generation platforms — a stint that stretched over three and a half years. He also delivered keynote addresses at the Linux Foundation North America Summit and SHIFT AI Global Conference. In 2022, he joined the cyber-intelligence startup as a machine learning intern, developing pipelines to detect disinformation threats across social media. But it was his leap to SpaceX in 2023 that placed him on a global stage. As a software engineer at Starlink, Quazi worked on network beam planning and optimization, designing production-critical systems that determine how satellites target internet beams worldwide. 'It required a deep understanding of low-latency, high-performance computing and real-time programming,' his LinkedIn profile notes. Why Wall Street over AI labs Given his track record, Quazi had no shortage of offers from leading AI labs and technology firms. But he chose Citadel Securities for its blend of intellectual complexity and speed. 'Quant finance offers a pretty rare combination: the complexity and intellectual challenge that AI research also provides, but with a much faster pace,' he explained to Business Insider . 'At Citadel Securities, I'll be able to see measurable impact in days, not months or years.' The firm's meritocratic approach also appealed to him. Unlike many institutions that might hesitate at his age, Citadel evaluated him solely on skill. Life beyond algorithms Moving to Manhattan represents more than just a career pivot. For the first time, Quazi will live independently, walking to work instead of relying on his mother to drive him to SpaceX's Redmond office — a reminder that despite his resume, he is still a teenager navigating milestones most reach much later. Lessons from Quazi's path For students and educators, Quazi's story is not just one of precocity but of possibility. His journey highlights how alternative educational pathways — early college, project-based learning, and industry immersion — can cultivate talent far earlier than traditional timelines allow. As Wall Street, Silicon Valley, and AI labs compete for minds like his, the deeper lesson is clear: The future belongs to those willing to blur the boundaries between age, discipline, and convention.
