Fuel leaks threaten to delay launch of new NASA moon rocket
Cape Canaveral, Aug 29: Fuel leaks during final liftoff preparations threatened to postpone the launch of NASA's mighty new moon rocket Monday morning on its shakedown flight with three test dummies aboard.
As precious minutes ticked away, NASA repeatedly stopped and started the fuelling of the Space Launch System rocket with nearly 1 million gallons of super-cold hydrogen and oxygen because of a leak.
The fuelling already was running nearly an hour late because of thunderstorms off Florida's Kennedy Space Centre.
The leak of highly explosive hydrogen appeared in the same place that saw seepage during a dress rehearsal back in the spring.
Then a second apparent hydrogen leak turned up in a valve that had caused trouble in June but that NASA thought it had fixed, officials said.
Later in the morning, NASA officials spotted what they feared was a crack or some other defect on the core stage the big orange fuel tank with four main engines on it but they later said it appeared to be just a buildup of frost.
The rocket was set to lift off on a mission to put a crew capsule into orbit around the moon.
The launch represents a milestone in America's quest to put astronauts back on the lunar surface for the first time since the Apollo programme ended 50 years ago.
NASA's assistant launch director, Jeremy Graeber, said after the repeated struggles with the first leak that the space agency would have to decide whether to go forward with the Monday morning launch.
"We have a lot of work to get to that point," Graeber cautioned.
If NASA scrubbed Monday's launch, the next attempt wouldn't be until Friday at the earliest.
The 322-foot spaceship is the most powerful rocket ever built by NASA, out-muscling even the Saturn V that took the Apollo astronauts to the moon.
No astronauts were inside the rocket's Orion capsule.
Instead, the test dummies, fitted with sensors to measure vibration, cosmic radiation and other conditions, were strapped in for the six-week mission, scheduled to end with the capsule's splashdown in the Pacific in October.
Even though no one was on board, thousands of people jammed the coast to see the rocket soar.
Vice President Kamala Harris was expected among the VIPs.
The launch is the first flight in NASA's 21st-century moon-exploration programme, named Artemis after Apollo's mythological twin sister.
Assuming the test goes well, astronauts will climb aboard for the second flight and fly around the moon and back as soon as 2024.
A two-person lunar landing could follow by the end of 2025.
The problems seen Monday were reminiscent of NASA's space shuttle era, when hydrogen fuel leaks disrupted countdowns and delayed a string of launches back in 1990.
Launch director Charlie Blackwell-Thompson and her team also had to deal with a communication problem involving the Orion capsule.
Engineers scrambled to understand an 11-minute delay in the communication lines between launch control and Orion that cropped up late Sunday.
Though the problem had cleared by Monday morning, NASA needed to know why it happened before committing to a launch.

LPG crisis: Karnataka temples gear up to stock wooden logs for ‘Prasada’
Bengaluru (PTI): Temples in Karnataka have started preparations to stock wooden logs fearing that the LPG shortage could hamper the ‘Prasada’ preparation and distributions to the devotees.
The looming LPG crisis in the state in the wake of Iran-Israel conflict has made the temple managements jittery.
According to the Akhila Karnataka Hindu Temple Archakas Federation (AKHTAF) president M S Venkatachalaiah, there is no immediate crisis in the temples.
“We have LPG cylinder stock that can last for a week but if this scarcity continues then there will be a problem in serving Prasada (offerings to the deity) to the devotees,” AKHTAF president said.
He added that many temples in the state have started stocking wooden logs to overcome the LPG crisis.
“Our temples have started preparing to store wooden logs to prepare Prasada though currently we don’t have a problem, at least for a week,” Venkatachalaiah told PTI.
Another priest working in a temple belonging to the state Endowment Department said the temples may have to go back to the traditional way of cooking as done in the ancient time using wood.
The LPG crisis has not affected the mid-day meal programme for government school students yet, though there was a meeting in the Education Department to find ways to tackle if crisis deepens, sources associated with the Mid-day Meal programme said.
Meanwhile, the largest partner of the Mid-day Meal programme in the country is Akshaya Patra.
The NGO said they do not depend much on LPG gas cylinder.
“The LPG crisis has not affected us. Our kitchens are steam-based, and we generate steam through boilers which run on electricity. That’s point number one. Point number two—gas is used only for very minor things, mainly for seasoning. That is the tadka,” an Akshaya Patra executive told PTI.
According to him, the NGO has has a gas reserves for about nearly one month across India, though gas is used in very small quantities every day.
He pointed out that the Mid-day meal programme will not be affected because in one or one-and-a-half weeks, schools will close owing to summer vacation.
Akshaya Patra feeds 23.5 lakh children across more than 24,000 schools across India, in 16 states and three Union Territories, he said.
