Shubhanshu Shuklas Space Quest Stalled: How Falcon 9 Leak Halted Axiom-4 Again? Know Here
Postponement of Axiom 04 mission slated for launch on 11th June 2025 for sending first Indian Gaganyatri to ISS.
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… — ISRO (@isro) June 11, 2025
Technical Snag Halts Launch
SpaceX stated on X that extra time is necessary to correct a LOx leak discovered on post-static fire booster inspections. "Standing down from tomorrow's Falcon 9 launch of Ax-4 to the @Space_Station to allow SpaceX teams to repair the LOx leak," the company said, noting that a new launch date will be based on repair progress and availability of the launch range.
ISRO gave additional information, stating that the leak was detected in the propulsion bay during a seven-second hot test on the launch pad. "It has been decided to fix the leak and perform necessary validation tests prior to clearing for launch," ISRO tweeted on X. The move came after consultations among ISRO, Axiom Space, and SpaceX experts.
Second Postponement In Days
The Axiom-4 mission, which was initially planned for June 10, 2025, was initially postponed to June 11 at 5:30 PM IST due to inclement weather, as notified by ISRO on Monday. The new technical snag has again postponed the mission, which will take Shukla, India's first "Gaganyatri" under the Gaganyaan program, to the ISS for a 14-day scientific mission.
Mission Significance
Shukla, a 39-year-old Indian Air Force Group Captain and test pilot, was chosen for the Axiom-4 mission, a three-way collaboration between ISRO, Axiom Space, and NASA. The mission will consist of experiments in microgravity, outreach, and technology demonstrations, a new milestone for India's human spaceflight program. Shukla's journey was expected to motivate millions, with Prime Minister Narendra Modi emphasising its importance to India's space program.
Next Steps
SpaceX and ISRO are attempting to fix the LOx leak, with testing validation necessary before a new launch can be dated. The postponement has led to debate on X, with users disappointed but understanding the priority on safety. ISRO highlighted that tough checks guarantee astronaut safety, explaining, "The mission will proceed only after all systems are fully validated."
More information on the launch timeline should soon be available as teams work to resolve the technical problem and watch for weather at Florida's Kennedy Space Center.

Donald Trump's Golden Dome looks for alternatives to Musk's SpaceX
The Trump administration is expanding its search for partners to build the Golden Dome missile defense system, courting Project Kuiper and big defense contractors as tensions with Elon Musk threaten SpaceX's dominance in the program, according to three sources familiar with the matter. The shift marks a strategic pivot away from reliance on Musk's SpaceX, whose Starlink and Starshield satellite networks have become central to U.S. military communications. It comes amid a deteriorating relationship between Trump and Musk, which culminated in a public falling-out on June 5. Even before the spat, officials at the Pentagon and White House had begun exploring alternatives to SpaceX, wary of over-reliance on a single partner for huge portions of the ambitious, $175 billion space-based defense shield, two of the sources said. Musk and SpaceX did not respond to requests for comment. After Reuters reported initially that SpaceX was a frontrunner to build parts of Golden Dome, Musk said on X that the company had "not tried to bid for any contract in this regard. Our strong preference would be to stay focused on taking humanity to Mars." Due to its size, track record of launching more than 9,000 of its own Starlink satellites, and experience in government procurement, SpaceX still has the inside track to assist with major portions of the Golden Dome, especially launch contracts, sources say. Project Kuiper, which has launched just 78 of a planned constellation of 3,000 low-earth orbit satellites, has been approached by the Pentagon to join the effort, signaling the administration's openness to integrating commercial tech firms into national defense infrastructure and going beyond traditional defense players. Jeff Bezos, Amazon's executive chairman, told Reuters in January that Kuiper would be "primarily commercial," but acknowledged "there will be defense uses for these [low-earth orbit] constellations, no doubt." A spokesperson for Project Kuiper declined to comment for this story. The Pentagon declined to comment. The White House did not respond to requests for comment. Golden Dome's ambitions mirror those of Israel's Iron Dome - a homeland missile defense shield - but a larger, more complex layered defense system requires a vast network of orbiting satellites covering more territory. In the search for more vendors for the satellite layers of Golden Dome, "Kuiper is a big one," a U.S. official said. While SpaceX remains a frontrunner due to its unmatched launch capabilities, its share of the program could shrink, two of the people said. Officials have reached out to new entrants like rocket companies Stoke Space and Rocket Lab are gaining traction and will be able to bid on individual launches as the program matures, according to the U.S. official. Later in the development of Golden Dome "each individual launch is going to get bid, and we have to actually give bids to other people," besides SpaceX, the official said. NEED FOR SATELLITES There is an urgent need for more satellite production. Last year Congress gave Space Force a $13 billion mandate - up from $900 million - to buy satellite-based communication services in what was widely seen as one of many efforts to stimulate private sector satellite production. Amazon's Project Kuiper, a $10 billion initiative led by former Starlink managers dismissed by Musk for slow progress, Reuters has reported, has lagged behind SpaceX in deployment. But its potential defense applications - such as communications that could aid missile tracking - have drawn renewed interest as the administration prepares to allocate the first $25 billion tranche of funding authorized under Trump's sweeping tax and spending bill. Traditional defense giants Northrop Grumman, Lockheed Martin, and L3Harris are also in talks to support Golden Dome. L3Harris CFO Kenneth Bedingfield told Reuters in an interview the company has seen a surge in interest in its missile warning and tracking technologies, which are expected to play a key role in the system. Northrop, meanwhile, is pursuing several efforts including a space-based interceptor, a component that would enable missile strikes from orbit, Robert Fleming, the head of the company's space business, told Reuters in an interview. "Lockheed Martin is ready to support Golden Dome for America as a proven mission partner," Robert Lightfoot, president of Lockheed Martin Space, said in a statement. Golden Dome's initial outreach this spring invited smaller, newer Silicon Valley firms seen as nimbler, more sophisticated and potentially less expensive alternatives to the big defense firms to the table - but that was before the Musk-Trump feud upended that calculus. Several with close ties to Trump aside from SpaceX, including Palantir and Anduril - were considered early frontrunners to win big pieces of the $175 billion project. But the Musk-Trump feud has reshaped the competitive landscape. Musk recently launched the "America Party," a tech-centric, centrist political movement aimed at defeating Republicans who backed Trump's tax-and-spend agenda. RAPID TIMEFRAME Trump launched the Golden Dome initiative just a week into his second term, pushing for rapid deployment. Space Force General Michael Guetlein, confirmed by the Senate on July 17, is set to lead the program with sweeping authority. Under a previously unreported directive from Defense Secretary Pete Hegseth, Guetlein has 30 days from confirmation to build a team, 60 days to deliver an initial system design, and 120 days to present a full implementation plan, including satellite and ground station details, two people briefed on the memo said. The inclusion of commercial platforms like Kuiper raises security concerns. Its satellites would need to be hardened against cyberattacks and electronic warfare, a challenge that has plagued even SpaceX's Starlink network. In May 2024, Elon Musk said SpaceX was spending "significant resources combating Russian jamming efforts. This is a tough problem." Beyond the technical and political challenges, Golden Dome could reshape global security dynamics. A fully operational space-based missile shield may prompt adversaries to develop new offensive capabilities or accelerate the militarization of space. Still, established defense players like Lockheed and RTX, formerly Raytheon, will likely be at the front of the line for contracts. Executives at RTX, maker of the Patriot missile defense system, said on Tuesday they believe the system is going to be integral to Golden Dome "especially if you want to make a significant impact over the next 2 to 3 years."

Lift the veil, abandon Soviet-era approach. Indian science community wants ISRO to up its PR game
'A kid growing in India learns about NASA (US-based National Aeronautics and Space Administration) before it does ISRO because NASA puts so much effort into taking its work to its citizens and the public, from the smallest of things to the biggest,' 'Gareeb Scientist' said in a post on Tuesday. Since then, at least 11,000 people have viewed it. He is part of a digital war. The aim is to awaken the Indian Space Research Organisation (ISRO) from its 55-year-old slumber by demanding better public outreach and engagement by the space agency around its space missions and technology development. New Delhi: A science communicator and space enthusiast on social media under the pseudonym 'Gareeb Scientist' sat determined behind his keyboard Tuesday. As soon as the clock struck one, he hit enter on a flurry of posts on X, with the hashtag, 'ISROfixyourPR'. The Indian science community is currently waging a war against the veil around ISRO-supported operations, fighting with memes, personal anecdotes and a carefully crafted list of its work, which has remained hidden from public discourse. Many Indian social media accounts, which dedicatedly post space updates from ISRO, said the campaign started with the aim to highlight the lack of PR from the space agency. The issue also extended to big-ticket missions, such as the recent partnership between ISRO and US-based Axiom Space to jointly send Indian Air Force group captain Shubhanshu Shukla to the International Space Station (ISS). Experts said that the visibility of ISRO missions had improved over the last decade. However, they added, the burden of information dissemination remained limited to media houses and independent science communicators, who often obtained information outside of official statements. Radha Krishna Kavuluru, a space technology expert and former ISRO scientist, said ISRO, in the coming years, would conduct some inspiring missions that could inspire an entire generation of future space scientists. Kavuluru said that maximum public engagement would ensure that the public had an opportunity to celebrate the achievements of ISRO while they witnessed the indigenous scientific advancements. 'Keeping everything behind walls is a tradition of the Soviets. I am sure we are well past that age. Time to inspire and talk the walk,' Kavuluru told ThePrint. Also Read: ISRO commercial arm invites private players to build LVM3 rocket that delivered Chandrayaan mission Silence around recent missions On 25 June, IAF group captain Shubhanshu Shukla kicked off his journey to the ISS as a member of the US-run Axiom-4 mission. He became the first Indian to set foot on the ISS, and after Rakesh Sharma, the second Indian to travel to space. However, the buzz around the mission was limited to newspaper front pages and TV screens. The official social media pages of ISRO stayed content with reposting updates from the Union Minister of Science and Technology, Jitendra Singh. Between the 1 June Axiom-4 launch and its 15 July return to Earth, ISRO made 24 posts on its X account about the Axiom-4 mission, including 19 reposts of posts by the science minister, the Prime Minister's Office, or the Public Information Bureau. The remaining five posts on the ISRO X account informed about the multiple postponements of the launch and the technical faults that SpaceX's Falcon-9 rocket experienced. In the same period, NASA, through its various X handles, did a run-up to the launch with at least one post per day, while reposting engagement posts by Axiom Space and SpaceX. The US space agency, in partnership with Axiom Space, organised interaction sessions with the astronauts and released not only individual profile films for each but also infographics for the rocket launch and space capsule travel trajectory, among other actions. More recently, updates on missions, such as the demonstration of the advanced technology behind rendezvous, docking, and undocking of a spacecraft in space—SpaDeX—and the upcoming one-of-a-kind NASA-ISRO SAR (Synthetic Aperture Radar) Mission or NISAR, a joint Earth observation mission, have been few and far in between. On Monday, during the announcement of the NISAR launch date, ISRO's PR was limited to a post on X, as NASA held a formal press conference led by the team that will undertake the mission from the US space agency's end. The team members answered all media questions on all aspects of the mission. However, ISRO was not part of the press conference. Vikranth Jonna, a 22-year-old engineer with Hyderabad-based space tech startup Dhruva Space, listed the 'crazy cool' work ISRO has done for the mission. 'ISRO is currently building methalox engines, quantum communications, human spaceflight, reusable rockets, two landers to the Moon, a mission to Venus and a lander to Mars,' Jonna said. 'Give us more opportunities to appreciate our scientists and engineers. Show us your glory,' he added. ISRO refused to respond to ThePrint's request for a response to the ongoing social media campaign. A senior scientist confirmed to ThePrint that ISRO had 'gotten better' in its PR game but accepted that compared to its counterparts, such as NASA or European Space Agency (ESA), there is a long way to go. 'Of course, there is always room for improvement. But you need to acknowledge that the space sector in India has only started opening up, and some projects still need to operate with secrecy,' the scientist said. Also Read: Gujarat, Tamil Nadu, Karnataka to serve as 'manufacturing hubs' for India's homegrown space dreams Global competition From photos of astronauts working on the ISS and open-source data from active satellites to an easy-to-understand space glossary, the space PR game of NASA and its laboratories is top-class. Apart from its active presence, all over social media, including Facebook, LinkedIn, Instagram, and X, NASA has also been engaging with the general public through its programmes, such as the 'Get involved with NASA', where they invite members of the public to contribute their time and expertise to advancing research and solving problems, as well as potentially winning prizes as a result of their work. Its 'Citizen Science' project is open to the public all over the world and aims to collaborate with volunteers to promote discoveries. 'More than 450 NASA citizen scientists have been [so far] named as co-authors on refereed scientific publications,' the NASA website reads. Over the last few years, the ESA, China National Space Administration and Japan Aerospace Exploration Agency have also caught on. The agencies realised the global space domain was not only about what happened inside the laboratories, but that a significant portion of their space programme success also depended on how they presented themselves. For instance, the Japanese agency has been organising open houses, town meetings and laboratory tours to help promote the work happening at those sites. Mobilising interest in space When his 16-year-old nephew asked Kavuluru where he could find the link to a documentary on the ISRO Astrosat and Aditya-L1 missions—something on the lines of NASA's 'Cosmos: A Spacetime Odyssey' and 'Apollo-11'—the former ISRO scientist was hit with a sensation of embarrassment. 'He wanted to study how ISRO does deep space missions. I had no response because no such documentaries exist … Why is this the case? When we have done such complex missions and are observing the Sun and the stars, shouldn't Indian students have the luxury to observe them too?' Kavuluru asked. While ISRO missions remain under the shadows of mystery, the movie, as well as the OTT industry, has so far been cashing in on the public appetite for India's space success story. The Indian audiences have accepted 'Mission Mangal', 'Rocket Boys', 'Rocketry—The Nambi Effect', and 'Mission over Mars' with rave reviews. Be it Akshay Kumar portraying space pioneer Rakesh Dhawan, or R. Madhavan acting as senior scientist Nambi Narayanan—they have happily lapped it all up, with a feeling of pride. Now, they need an opportunity to applaud their real heroes. (Edited by Madhurita Goswami) Also Read: Russian rocket takes off with US astronaut on board, Putin's envoy hails joint space effort
