Why was Axiom-4 mission carrying Indian astronaut Sudhanshu Shukla delayed
Sudhanshu Shukla
was postponed moments before its scheduled launch on June 10 2025. The mission was first postponed due to bad weather at NASA's Kennedy Space Center in Florida. The postponement turned out to be extended after the discovery of a leak of liquid oxygen when engineers undertook a routine engine test. Liquid oxygen is a critical component of the rocket fuel system and a leak could cause substantial issues at launch time. In order to prevent risks the team interrupted the launch and repaired the problem before they continued. Safety inspections are a top priority for space missions because even the smallest technical malfunction will become a serious risk. There will be a new release date once all systems are cleared.
What is the Axiom-4 mission
The
Axiom-4 mission
is a private space mission that has been organized by Axiom Space collaboration with NASA and SpaceX. It will see four astronauts on board the International Space Station (ISS) for scientific research and international cooperation. Indian Air Force Group Captain Sudhanshu Shukla is a part of the crew, which is a matter of pride for India. The team will ride SpaceX's Falcon 9 rocket and Dragon spacecraft. The mission belongs to a developing trend of commercial space travel, blending public agency assistance with private ingenuity. It also creates new opportunities for nations such as India to be involved in human spaceflight missions beyond their domestic programs.

The launch was delayed after engineers discovered a leak of liquid oxygen (LOX) during a final 'hot fire' engine test. This pre-launch test involves firing the rocket's engines briefly to ensure they are functioning properly. The leak was found in the rocket's propulsion section, which holds key fuel and engine systems. Any fault in this area could be dangerous during liftoff. The team halted the mission immediately for safety. Such problems, as few as they are, are considered very seriously. It's safer to postpone a mission than to endanger the rocket for damage or the crew on board during flight or launch.
What is liquid oxygen and why is it used
Liquid oxygen, or LOX, is a highly cold and energetic oxidizer employed in rockets. Fuel in the rocket uses oxygen for combustion. The engines on Earth can burn oxygen taken from the air, space does not have an atmosphere, so rockets have to bring their own. LOX is mixed with fuels such as kerosene or hydrogen to provide the high-pressure burn required to take off. It is stored at very low temperatures—approximately minus 183 degrees Celsius—so it remains liquid. This makes it extremely efficient, but very risky if mishandled. LOX is an important component used in contemporary rocket launches worldwide.
Why is a LOX leak dangerous
Liquid oxygen is extremely reactive and can be dangerous even with a small leak. Liquid oxygen can create frost buildup, pressure unevenness, and, upon contact with fuel or some materials, it could initiate fire or explosion. In a rocket, temperatures and pressures are extreme, and even a minor malfunction in LOX can be disastrous. That's why the engineers halted the Axiom-4 mission the moment they detected the leak. LOX handling demands strict safety measures, and crews need to be 100% certain the system is sealed, stable, and secure before proceeding with launch operations.
What follows next
Following the leak detection, SpaceX engineers halted the mission to correct the malfunction and conduct further safety tests. These tests are imperative to make the rocket safe and reliable for the astronauts on board. A fresh launch date will be fixed after everything is cleared. The mission can be postponed by days or possibly weeks, but safety first. For now, the team is concentrating on fixing the issue in full before going ahead. It's a standard procedure in space travel, where every minute detail needs to be checked twice. The astronauts, including Shukla, are still in training and standby for the rescheduled launch.
Why this mission is important
Axiom-4 mission is a milestone moment for India and the future of international space collaboration. Despite the setback, it's a moment of pride as Shukla becomes part of the elite group of Indians to travel into space. His participation in the mission signifies India's increasing capabilities and presence in the space industry. It also opens the door for more public-private collaborations and international manned missions. Science is not the only purpose of this flight but inspiration, too. Millions of Indians look on, particularly schoolchildren, who might one day envision themselves as astronauts. The mission will proceed soon, carrying those aspirations on its wings.

Issue between EC, Congress should not be discussed in Parliament: Rijiju
Union Parliamentary Affairs Minister Kiren Rijiju on Monday called on Congress and other opposition parties to refrain from creating disruptions in Parliament over issues related to the Election Commission. Rijiju, while speaking at a press conference, stated that any disputes between the Election Commission and political parties should be discussed directly with the EC, and not in the Parliament. "The issue between the Election Commission and the Congress party should be discussed in the Election Commission and not in the Parliament. We are not the spokespersons of ECI. ECI is an autonomous body, and we cannot answer on behalf of them..." he added. He urged the opposition not to "create a ruckus" over issues related to the Election Commission. Rijiju said, "As far as Congress and other political parties are concerned, they created a ruckus in the House over the issue of the Election Commission. I request that they refrain from creating a ruckus during this discussion." Rijiju also announced that Parliament will hold a special discussion to honour Captain Shubhanshu Shukla and his recent space visit to the International Space Station (ISS) as part of India's space mission. "In the Parliament, today, we are going to honour Captain Shubhanshu Shukla through a special discussion. We will discuss his space visit and India's space mission in detail," Rijiju said. He expressed hope that members from all parties would participate positively, similar to the bipartisan support witnessed during the recent discussion on Operation Sindoor. "I hope that the way all the members of all parties took part in the discussion on Operation Sindoor, the same way all parties will congratulate Captain Shubhanshu Shukla and Indian scientists and take part in this discussion..." he added. Shukla, who returned to Earth on July 15 after completing NASA's Axiom-4 (AX-4) space mission, landed in Delhi in the early hours of Sunday. Shukla was part of NASA's Axiom-4 Space Mission, which took off from NASA's Kennedy Space Centre in Florida, US, on June 25. He returned to Earth on July 15, splashing down off the coast of California. He became the first Indian in 41 years to travel to space.

Astronaut Shubhanshu Shukla to meet PM Narendra Modi today
A day after returning to India after successful maiden mission to the International Space Station, astronaut Shubhanshu Shukla is likely to meet Prime Minister Narendra Modi on meeting comes as parliament decided to honour his achievement with a special discussion. Union Parliamentary Affairs Minister Kiren Rijiju confirmed the decision, calling Shukla's accomplishment "a historic milestone for the nation".Rijiju said, "Our hero astronaut Capt. Subhanshu Shukla has returned home after a successful mission to the International Space Station. Parliament will honour him with a special discussion on this remarkable achievement and India's growing space ambitions in our journey to the stars".advertisement Shux, who is a serving Indian Air Force Test Pilot, went to space earlier this year on his maiden mission as part of the Axiom-4 mission. He served as Mission Pilot alongside three other crew members. He conducted seven experiments sent by the Indian Space Research Organisation (Isro), all related to India's own human spaceflight program Gaganyaan Mission. His work aboard the ISS included key scientific experiments on microgravity's impact on human physiology and advanced research in material sciences. Shux's contributions not only garnered global recognition but also demonstrated India's increasing role in collaborative space returned to India with his fellow astronaut Gp. Capt. P Balakrishnan Nair, who was the backup astronaut for the Ax-4 mission. 'As I sit on the plane to come back to India, I have a mix of emotions running through my heart. I feel sad leaving a fantastic group of people behind who were my friends and family for the past year during this mission. I am also excited about meeting all my friends, family and everyone in the country for the first time post mission. I guess this is what life is — everything all at once,' Shux wrote ahead of his Shukla and Nair are part of India's Gaganyaan astronaut corps and are set to resume training with two other astronauts in October at Isro's Human Space Flight Centre (HSFC).India is planning to launch maiden crewed Gaganyaan Mission to space in 2027, buikld a Bharatiya Antriksh Station by 2035 and land a man on the Moon by 2040.- EndsMust Watch

NASA plans to build a nuclear reactor on the moon
The first space race was about flags and footprints. Now, decades later, landing on the Moon is old news. The new race is to build there, and doing so hinges on power. In April 2025, China reportedly unveiled plans to build a nuclear power plant on the Moon by 2035. This plant would support its planned international lunar research station. The United States countered in August, when acting NASA Administrator Sean Duffy reportedly suggested a U.S. reactor would be operational on the Moon by 2030. While it might feel like a sudden sprint, this isn't exactly breaking news. NASA and the Department of Energy have spent years quietly developing small nuclear power systems to power lunar bases, mining operations and long-term habitats. As a space lawyer focused on long-term human advancement into space, I see this not as an arms race but as a strategic infrastructure race. And in this case, infrastructure is influence. A lunar nuclear reactor may sound dramatic, but its neither illegal nor unprecedented. If deployed responsibly, it could allow countries to peacefully explore the Moon, fuel their economic growth and test out technologies for deeper space missions. But building a reactor also raises critical questions about access and power. Existing legal framework Nuclear power in space isn't a new idea. Since the 1960s, the U.S. and the Soviet Union have relied on radioisotope generators that use small amounts of radioactive elements – a type of nuclear fuel – to power satellites, Mars rovers and the Voyager probes. The United Nations' 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space, a nonbinding resolution, recognizes that nuclear energy may be essential for missions where solar power is insufficient. This resolution sets guidelines for safety, transparency and international consultation. Nothing in international law prohibits the peaceful use of nuclear power on the Moon. But what matters is how countries deploy it. And the first country to succeed could shape the norms for expectations, behaviors and legal interpretations related to lunar presence and influence. Why being first matters The 1967 Outer Space Treaty, ratified by all major spacefaring nations including the U.S., China and Russia, governs space activity. Its Article IX requires that states act with 'due regard to the corresponding interests of all other States Parties.' That statement means if one country places a nuclear reactor on the Moon, others must navigate around it, legally and physically. In effect, it draws a line on the lunar map. If the reactor anchors a larger, long-term facility, it could quietly shape what countries do and how their moves are interpreted legally, on the Moon and beyond. Other articles in the Outer Space Treaty set similar boundaries on behavior, even as they encourage cooperation. They affirm that all countries have the right to freely explore and access the Moon and other celestial bodies, but they explicitly prohibit territorial claims or assertions of sovereignty. At the same time, the treaty acknowledges that countries may establish installations such as bases — and with that, gain the power to limit access. While visits by other countries are encouraged as a transparency measure, they must be preceded by prior consultations. Effectively, this grants operators a degree of control over who can enter and when. Building infrastructure is not staking a territorial claim. No one can own the Moon, but one country setting up a reactor could shape where and how others operate – functionally, if not legally. Infrastructure as influence Building a nuclear reactor establishes a country's presence in a given area. This idea is especially important for resource-rich areas such as the lunar south pole, where ice found in perpetually shadowed craters could fuel rockets and sustain lunar bases. These sought-after regions are scientifically vital and geopolitically sensitive, as multiple countries want to build bases or conduct research there. Building infrastructure in these areas would cement a country's ability to access the resources there and potentially exclude others from doing the same. Critics may worry about radiation risks. Even if designed for peaceful use and contained properly, reactors introduce new environmental and operational hazards, particularly in a dangerous setting such as space. But the U.N. guidelines do outline rigorous safety protocols, and following them could potentially mitigate these concerns. The Moon has little atmosphere and experiences 14-day stretches of darkness. In some shadowed craters, where ice is likely to be found, sunlight never reaches the surface at all. These issues make solar energy unreliable, if not impossible, in some of the most critical regions. A small lunar reactor could operate continuously for a decade or more, powering habitats, rovers, 3D printers and life-support systems. Nuclear power could be the linchpin for long-term human activity. And it's not just about the Moon – developing this capability is essential for missions to Mars, where solar power is even more constrained. Call for governance, not alarm The United States has an opportunity to lead not just in technology but in governance. If it commits to sharing its plans publicly, following Article IX of the Outer Space Treaty and reaffirming a commitment to peaceful use and international participation, it will encourage other countries to do the same. The future of the Moon won't be determined by who plants the most flags. It will be determined by who builds what, and how. Nuclear power may be essential for that future. Building transparently and in line with international guidelines would allow countries to more safely realize that future. A reactor on the Moon isn't a territorial claim or a declaration of war. But it is infrastructure. And infrastructure will be how countries display power – of all kinds – in the next era of space exploration. Michelle L.D.
