UAE, NASA missions find 'patchy' proton auroras in Mars atmosphere

The United Arab Emirate's Mars Mission (EMM) and NASA's MAVEN probe have found "patchy" proton auroras in Mars' skies, providing new insights into the red planet's atmosphere. An aurora is a natural light display in a planet's sky, predominantly seen in high-latitude regions such as the northern lights, or the aurora borealis, seen from the Earth. The new aurora found by the team is formed when the solar wind directly impacts Mars' upper atmosphere and emits ultraviolet light as it slows down. It was discovered in snapshots of the dayside disk obtained by the Emirates Mars Ultraviolet Spectrometer (EMUS), which observes the planet's upper atmosphere. When the aurora occurs, small regions of the planet become much brighter, signifying intense localised energy in the atmosphere. "Our discovery of these patchy proton aurora adds a new kind of event to the long list of those currently studied by EMM and challenges our existing views of how the proton aurora on Mars' dayside are formed

NASA to make another attempt of launching Artemis Moon Rocket on Saturday

NASA will try again Saturday to launch its new moon rocket on a test flight, after engine trouble halted the first countdown this week. Managers said Tuesday they are changing fueling procedures to deal with the issue. The 322-foot (98-meter) rocket remains on its pad at Kennedy Space Center, with an empty crew capsule on top. It's the most powerful rocket ever built by NASA. The Space Launch System rocket, or SLS, will attempt to send the capsule around the moon and back. No one will be aboard, just three test dummies. If successful, it will be the first capsule to fly to the moon since NASA's Apollo program 50 years ago. During Monday's launch attempt, one of the four main engines in the rocket's core stage could not be chilled sufficiently prior to planned ignition moments before liftoff. The three others came up just a little short. The chilling operation will be conducted a half-hour earlier for Saturday afternoon's try, once fueling is underway at the pad, officials said. J

Fuel leaks and possible crack threaten to delay NASA moon rocket launch

Fuel leaks and a possible crack discovered during final liftoff preparations threatened to delay 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 appeared in the same place that saw seepage during a dress rehearsal back in the spring. Then a second apparent leak in a valve turned up, officials said. Later in the morning, a crack or some other defect was spotted on the core stage the big orange fuel tank with four main engines on it with frost appearing around the suspect area, NASA officials said. Engineers began studying the buildup. The rocket was set to lift off on a mission to put a crew caps

NASA fuels moon rocket ahead of liftoff on first test flight today

NASA began fuelling its new moon rocket early Monday for liftoff on a test flight to put a crew capsule into lunar orbit for the first time in 50 years. Thunderstorms delayed the fuelling operation by an hour. The threat of lightning diminished enough to allow the launch team to proceed with loading the rocket's tanks. But it was uncertain how much the stalled work might shorten the two-hour launch window. No one was inside the Orion capsule atop the 322-foot (98-meter) rocket at Kennedy Space Center. Instead, three test dummies were strapped in for the lunar-orbiting mission, expected to last six weeks. It's the most powerful rocket ever built by NASA, out-muscling the Saturn V that carried astronauts to the moon a half-century ago. Thousands of people jammed the coast to see the Space Launch System, or SLS, rocket soar. Rain pelted the launch site as the launch team finally began loading more than 1 million gallons of super-cold fuel into the rocket. Forecasters remained optimist

NASA to test high-stakes new moon rocket next week, 50 years after Apollo

Years late and billions over budget, NASA's new moon rocket makes its debut next week in a high-stakes test flight before astronauts get on top. The 322-foot rocket will attempt to send an empty crew capsule into a far-flung lunar orbit, 50 years after NASA's famed Apollo moonshots. If all goes well, astronauts could strap in as soon as 2024 for a lap around the moon, with NASA aiming to land two people on the lunar surface by the end of 2025. Liftoff is set for Monday morning from NASA's Kennedy Space Center. The six-week test flight is risky and could be cut short if something fails, NASA officials warn. We're going to stress it and test it. We're going make it do things that we would never do with a crew on it in order to try to make it as safe as possible, NASA Administrator Bill Nelson told The Associated Press on Wednesday. The retired founder of George Washington University's space policy institute said a lot is riding on this trial run. Spiraling costs and long gaps betwe
