NASA's Webb Space telescope spots early galaxies hidden from Hubble

NASA's Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million (35 crore) years after the cosmic-creating Big Bang. Astronomers said on Thursday that if the results are verified, this newly-discovered throng of stars would beat the most distant galaxy identified by the Hubble Space Telescope, a record-holder that formed 400 million (40 crore) years after the universe began. Launched last December as a successor to Hubble, the Webb telescope is indicating stars may have formed sooner than previously thought -- perhaps within a couple million years of creation. Webb's latest discoveries were detailed in the Astrophysical Journal Letters by an international team led by Rohan Naidu of the Harvard-Smithsonian Center for Astrophysics. The article elaborates on two exceptionally bright galaxies, the first thought to have formed 350 million years after the Big Bang and the other 450 million (45 crore)

NASA's Artemis mission on way to Moon after launch by giant new rocket

A space capsule hurtled toward the moon on Wednesday for the first time in 50 years, following a thunderous launch of NASA's mightiest rocket in a dress rehearsal for astronaut flights. No one was on board this debut flight, just three test dummies. The capsule is headed for a wide orbit around the moon and then a return to Earth with a Pacific splashdown in about three weeks. After years of delays and billions in cost overruns, the Space Launch System rocket roared skyward, rising from Kennedy Space Center on 8.8 million pounds (4 million kilograms) of thrust and hitting 100 mph (160 kph) within seconds. The Orion capsule was perched on top and, less than two hours into the flight, busted out of Earth's orbit toward the moon. It was pretty overwhelming, said NASA Administrator Bill Nelson. We're going out to explore the heavens, and this is the next step." The moonshot follows nearly three months of vexing fuel leaks that kept the rocket bouncing between its hangar and the pad. .

NASA's mightiest moon rocket Artemis 1 blasts off 50 years after Apollo

NASA's new moon rocket blasted off on its debut flight with three test dummies aboard early Wednesday, bringing the US, a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo programme 50 years ago. If all goes well during the three-week, make-or-break shakedown flight, the rocket will propel an empty crew capsule into a wide orbit around the moon, and then the capsule will return to Earth with a splashdown in the Pacific in December. After years of delays and billions in cost overruns, the Space Launch System rocket thundered skyward, rising from Kennedy Space Centre 4 million kilograms of thrust and hitting 160 kph within seconds. The Orion capsule was perched on top, ready to bust out of Earth orbit toward the moon not quite two hours into the flight. The moonshot follows nearly three months of vexing fuel leaks that kept the rocket bouncing between its hangar and the pad. Forced back indoors by Hurricane Ian at the end

NASA fuelling new moon rocket for launch after leaks, hurricanes

NASA began fuelling its new moon rocket on Tuesday for a middle-of-the-night launch, its third try to put an empty capsule around the moon for the first time in 50 years. Fuel leaks plagued the first two attempts in late summer, then a pair of hurricanes caused more delays. While engineers never pinpointed the cause of the escaping hydrogen, they altered the fuelling process to minimise leakage and were confident that all the plumbing in the 322-foot (98-metre) rocket would remain tight and intact. NASA added an hour to the operation to account for the slower fill-up, vital for reducing pressure on the fuel lines and keeping the seals in place. It seemed to work, with no major leakages reported during the early stages. "So far, everything is going very smoothly," said assistant launch director Jeremy Graeber about an hour into fuelling. The rocket was being gassed up with nearly one million gallons (3.7 million litres) of super-cold hydrogen and oxygen. After more than four hours,

NASA: Moon rocket endured hurricane, set for 1st test flight next week

NASA's moon rocket needs only minor repairs after enduring a hurricane at the pad and is on track for its first test flight next week, a top official said on Friday. Right now, there's nothing preventing us" from attempting a launch on Wednesday, said NASA's Jim Free, an associate administrator. The wind never exceeded the rocket's design limits as Hurricane Nicole swept through Kennedy Space Centre on Thursday, according to Free. But he acknowledged if the launch team had known in advance that a hurricane was going to hit, they likely would have kept the rocket indoors. The rocket was moved out to the pad late last week for its USD 4.1 billion demo mission. Gusts reached 100 mph (160 kph) atop the launch tower, but were not nearly as strong farther down at the rocket. Computer models indicate there should be no strength or fatigue issues from the storm, even deep inside the rocket, Free noted. NASA had been aiming for an early Monday launch, but put it on hold for two days becau

Smashing success: Nasa's 'save-the-world test' strike results in big nudge

A spacecraft that plowed into a small, harmless asteroid millions of miles away succeeded in shifting its orbit, NASA said Tuesday in announcing the results of its save-the-world test. The space agency attempted the first test of its kind two weeks ago to see if in the future a killer rock could be nudged out of Earth's way. The Dart spacecraft carved a crater into the asteroid Dimorphos on Sept 26, hurling debris out into space and creating a cometlike trail of dust and rubble stretching several thousand miles (km). It took days of telescope observations to determine how much the impact altered the path of the 525-foot (160-metre) asteroid around its companion, a much bigger space rock. Before the impact, the moonlet took 11 hours and 55 minutes to circle its parent asteroid. Scientists had hoped to shave off 10 minutes but NASA Administrator Bill Nelson said the impact altered the asteroid's orbit by about 32 minutes. This mission shows that NASA is trying to be ready for whateve
