Fuel leak disrupts NASA's 2nd shot at launching moon rocket
Cape Canaveral (US), Sep 3: NASA's new moon rocket sprang another hazardous leak on Saturday, as the launch team began fuelling it for liftoff on a test flight that must go well before astronauts climb aboard.
For the second time this week, the launch team began loading nearly 1 million gallons of fuel into the 322-foot (98-metre) rocket, the most powerful ever built by NASA. Monday's attempt was halted by a bad engine sensor and leaking fuel.
As the sun rose, an over-pressure alarm sounded and the tanking operation was briefly halted, but no damage occurred and the effort resumed. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket.
NASA halted the operation, while engineers scrambled to plug what was believed to be a gap around a seal in the supply line.
The countdown clocks continued ticking toward an afternoon liftoff; NASA had two hours on Saturday to get the rocket off.
NASA wants to send the crew capsule atop the rocket around the moon, pushing it to the limit before astronauts get on the next flight.
If the five-week demo with test dummies succeeds, astronauts could fly around the moon in 2024 and land on it in 2025. People last walked on the moon 50 years ago.
Forecasters expected generally favourable weather at Kennedy Space Centre, especially toward the end of the two-hour afternoon launch window.
On Monday, hydrogen fuel escaped from elsewhere in the rocket. Technicians tightened up the fittings over the past week, but launch director Charlie Blackwell-Thompson stressed that she wouldn't know whether everything was tight until Saturday's fuelling.
Even more of a problem on Monday, a sensor indicated one of the rocket's four engines was too warm, but engineers later verified it actually was cold enough.
The launch team planned to ignore the faulty sensor this time around and rely on other instruments to ensure each main engine was properly chilled.
Before igniting, the main engines need to be as frigid as the liquid hydrogen fuel flowing into them at minus-420 degrees Fahrenheit (minus-250 degrees Celsius).
If not, the resulting damage could lead to an abrupt engine shutdown and aborted flight.
Mission managers accepted the additional risk posed by the engine issue as well as a separate problem: cracks in the rocket's insulating foam. But they acknowledged other problems like fuel leaks could prompt yet another delay.
That didn't stop thousands from jamming the coast to see the Space Launch System rocket soar. Local authorities expected massive crowds because of the long Labour Day holiday weekend.
The USD 4.1 billion test flight is the first step in NASA's Artemis programme of renewed lunar exploration, named after the twin sister of Apollo in Greek mythology.
Twelve astronauts walked on the moon during NASA's Apollo program, the last time in 1972.
Artemis years behind schedule and billions over budget aims to establish a sustained human presence on the moon, with crews eventually spending weeks at a time there. It's considered a training ground for Mars.

CM Siddaramaiah meets PM Modi, seeks urgent clearances for two irrigation projects
New Delhi (PTI): Karnataka Chief Minister Siddaramaiah on Friday met Prime Minister Narendra Modi, requesting rectification in short term farm loan limit, Rs 10,000 cr in financial support and urgent clearances for the Mekedatu Balancing Reservoir and Kalasa Bandhuri projects.
In the meeting in Parliament complex, Siddarmaiah pressed for several key interventions focusing on critical areas, including agriculture, water resources and urban infrastructure.
Deputy Chief Minister and Irrigation Minister D K Shivakumar, Energy Minister K J George and Urban Development Minister Byrathi Suresh accompanied the CM for the meeting.
The chief minister highlighted that NABARD has drastically cut the Short Term Agricultural Credit Limit for Karnataka from Rs 5,600 crore in 2023-24 to just Rs 2,340 crore in 2024-25, a 58 per cent reduction that could severely impact farmers' access to soft loans.
"I request you to look into this and direct the Finance Ministry to rectify this situation so that farmers in Karnataka continue to receive soft agricultural loans," Siddarmaiah said in a representation made to the PM.
He requested Rs 5,300 crore for the Upper Bhadra Project, which promises to irrigate central Karnataka's drought-prone farmlands. The project has been pending since the 2023-24 Union Budget.
He also pushed for clearances of two critical water projects - the Mekedatu Balancing Reservoir on the Kaveri river and the Kalasa Bandhuri project on the Mahadayi river -- both awaiting approvals from the Jal Shakti and Environment Ministries.
Highlighting Bengaluru's status as a tech hub and top GDP contributor, the state requested special assistance for urban and public transportation.
Additionally, Karnataka sought Rs 10,000 cr to develop infrastructure in 13 emerging city corporations.
On fiscal allocation, the CM complained of receiving an unfavourable deal from the 15th Finance Commission, which reduced its tax share by 1 per cent.
Siddaramaiah urged the government to provide compensation grants and ensure future finance commissions do not penalise states with significant tax contributions.
The Karnataka chief minister also met Congress leader Priyanka Gandhi Vadra and congratulated her on being elected as an MP from Wayanad.
