Australian and US scientists successfully launched a supersonic scramjet engine at an Outback test range yesterday, as they work on a device that could revolutionize air travel.
The researchers said that a rocket carrying the scramjet reached speeds of mach 10 -- 10 times the speed of sound -- after blasting off at the Woomera range in South Australia yesterday.
They said it reached an altitude of 530km before the scramjet was successfully deployed following re-entry to the Earth's atmosphere.
Australia's Defense Science and Technology Organization (DSTO) said it was believed to be the first time a scramjet had been ignited within the Earth's atmosphere.
"It looks like we've been very successful," DSTO spokesman Steve Butler said. "We've got to go away and collate the data, that will take a few weeks, but it looks very promising."
Scramjets are supersonic combustion engines that use oxygen from the atmosphere for fuel, making them lighter and faster than fuel-carrying rockets.
Scientists hope that one day a scramjet aircraft fired into space could cut traveling time from Sydney to London to as little as two hours.
The collapse of the Swiss Birch glacier serves as a chilling warning of the escalating dangers faced by communities worldwide living under the shadow of fragile ice, particularly in Asia, experts said. Footage of the collapse on Wednesday showed a huge cloud of ice and rubble hurtling down the mountainside into the hamlet of Blatten. Swiss Development Cooperation disaster risk reduction adviser Ali Neumann said that while the role of climate change in the case of Blatten “still needs to be investigated,” the wider impacts were clear on the cryosphere — the part of the world covered by frozen water. “Climate change and
Poland is set to hold a presidential runoff election today between two candidates offering starkly different visions for the country’s future. The winner would succeed Polish President Andrzej Duda, a conservative who is finishing his second and final term. The outcome would determine whether Poland embraces a nationalist populist trajectory or pivots more fully toward liberal, pro-European policies. An exit poll by Ipsos would be released when polls close today at 9pm local time, with a margin of error of plus or minus 2 percentage points. Final results are expected tomorrow. Whoever wins can be expected to either help or hinder the

DENIAL: Musk said that the ‘New York Times was lying their ass off,’ after it reported he used so much drugs that he developed bladder problems Elon Musk on Saturday denied a report that he used ketamine and other drugs extensively last year on the US presidential campaign trail. The New York Times on Friday reported that the billionaire adviser to US President Donald Trump used so much ketamine, a powerful anesthetic, that he developed bladder problems. The newspaper said the world’s richest person also took ecstasy and mushrooms, and traveled with a pill box last year, adding that it was not known whether Musk also took drugs while heading the so-called US Department of Government Efficiency (DOGE) after Trump took power in January.
