New space tech can charge electric cars in just five minutes: NASA

A new NASA-funded technology for future space missions may charge an electric car in just five minutes on Earth, paving the way for increased adoption of such vehicles, the US space agency said. Researchers at Purdue University, US developed the Flow Boiling and Condensation Experiment (FBCE) to enable two-phase fluid flow and heat transfer experiments to be conducted in the long-duration microgravity environment on the International Space Station (ISS). The new "subcooled flow boiling" technique results in greatly improved heat transfer effectiveness compared to other approaches and could be used to control the temperatures of future systems in space. This technology can also have applications on Earth: It could make owning an electric car more appealing, the researchers said. Currently, charging times vary widely, from 20 minutes at a station alongside a roadway to hours using an at-home charging station. Lengthy charging times and charger location are both cited as major concer

Russian cosmonaut launched to space from US, first time in 20 years

For the first time in 20 years, a Russian cosmonaut rocketed from the U.S. on Wednesday, launching to the International Space Station alongside NASA and Japanese astronauts despite tensions over the war in Ukraine. Their SpaceX flight was delayed by Hurricane Ian, which ripped across the state last week. I hope with this launch we will brighten up the skies over Florida a little bit for everyone, said the Japan Space Agency's Koichi Wakata, who is making his fifth spaceflight. Joining him on a five-month mission are three new to space: Marine Col. Nicole Mann, the first Native American woman bound for orbit; Navy Capt. Josh Cassada and Russia's lone female cosmonaut, Anna Kikina. They're due to arrive at the space station Thursday, 29 hours after departing NASA's Kennedy Space Center, and won't be back on Earth until March. They're replacing a U.S.-Italian crew that arrived in April. Kikina is the Russian Space Agency's exchange for NASA's Frank Rubio, who launched to the space ..

Why did NASA ram DART into an asteroid?

American space agency NASA recently conducted a planned mission to hit a cruising asteroid in space, as a part of its first planetary defense technology demonstration. Let's find out more about it

NASA's dress rehearsal: Spacecraft crashes into asteroid in defence test

A NASA spacecraft rammed an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth. The galactic grand slam occurred at a harmless asteroid 9.6 million kilometers away, with the spacecraft named Dart plowing into the small space rock at 22,500 kph. Scientists expected the impact to carve out a crater, hurl streams of rocks and dirt into space and, most importantly, alter the asteroid's orbit. Telescopes around the world and in space aimed at the same point in the sky to capture the spectacle. Though the impact was immediately obvious Dart's radio signal abruptly ceased it will be days or even weeks to determine how much the asteroid's path was changed. The USD 325 million mission was the first attempt to shift the position of an asteroid or any other natural object in space. "No, this is not a movie plot," NASA Administrator Bill Nelson tweeted earlier in the day. "We've all seen it on movies like Armageddon,' but the ...

NASA delays Artemis I launch for third time due to potential hurricane

NASA is skipping next week's launch attempt of its new moon rocket because of a tropical storm that's expected to become a major hurricane. It's the third delay in the past month for the lunar-orbiting test flight featuring mannequins but no astronauts, a follow-up to NASA's Apollo moon-landing programme of a half-century ago. Hydrogen fuel leaks and other technical issues caused the previous scrubs. Currently churning in the Caribbean, Tropical Storm Ian is expected to become a hurricane by Monday and slam into Florida's Gulf coast by Thursday. The entire state, however, is in the cone showing the probable path of the storm's center including NASA's Kennedy Space Centre. Given the forecast uncertainties, NASA decided Saturday to forgo Tuesday's planned launch attempt and instead prepare the 322-foot (98-metre) rocket for a possible return to its hangar. Managers will decide Sunday whether to haul it off the launch pad. If the rocket remains at the pad, NASA could try for an Oct

NASA again readies Artemis I Moon mission, troubleshoots hydrogen leak

The US space agency has once again readied its Artemis I moon mission and met all objectives, including the key hydrogen leak threat which has resulted in two failure attempts.

NASA's new moon rocket hit by fuel leaks in test ahead of final launch

NASA's new moon rocket sprouted more fuel leaks Wednesday in a test ahead of a possible launch attempt next week, but engineers managed to get them down to acceptable levels. There was no immediate word on whether NASA would try for a liftoff Tuesday given the sporadic nature of the hydrogen leaks, which have bedeviled the launch team for months. "Leaving a lot of folks scratching their heads on this one," said Launch Control's Derrol Nail. The daylong demo had barely begun when hazardous hydrogen fuel began escaping at the same place and same time as before, despite new seals and other repairs. Engineers halted the flow and warmed the lines in hopes of plugging the leak, and proceeded with the test. But the leak persisted before dropping to acceptable levels. Hours later, another leak cropped up elsewhere. Nail said all test objectives were met. But managers need to review the results before determining whether the 98-metre rocket is ready for its first test flight, a lunar-orbiti
