Pieces of distant, ancient asteroid arrive on Earth from Nasa spacecraft, after travelling billions of miles
A piece of asteroid has arrived on Earth from the other side of the solar system, in a major success for Nasa’s Osiris-Rex mission. The spacecraft has spent years flying to Asteroid Bennu, gathering up a piece of it, and bringing it back home so that it can be studied by researchers. It brings an end to a mission that took seven years, saw it travel 4 billion miles, and cost more than a billion dollars. Scientists hope that study can help reveal how planets formed and evolved, and might shed light on how life itself began. Since Bennu is around 4.5 billion years old, the sample is almost like a look back into the solar system during its early years and Nasa has referred to it as a “time capsule”. Asteroid Bennu is also notable as Nasa’s “most dangerous asteroid”, according to a scale used to measure how much of a hazard a given object poses. It is the first time that Nasa has brought back a piece of an asteroid, and the first time since 2020. It is also the biggest ever to be gathered, at around 250 grams. Nasa sent a team on board helicopters to gather the sample canister, extracting it to ensure that it did not become contaminated by the environment. Since the sample was directly from the asteroid, it will not have any trace of material from the Earth on it, unlike those that fall to Earth. That sample will be distributed between 200 people at 38 institutions across the world, including those in the UK. The Osiris-Rex mission left Earth in September 2016, and arrived at the asteroid in October 2018. It gathered samples in October 2020, and then left the asteroid in April 2021. Since then, both the sample and the spacecraft have been returning back from the other side of the solar system to Earth. The spacecraft then dropped off the sample to return home, while Osiris-Rex will carry on to study another asteroid called Apophis, where it will arrive in 2029. Apophis is also notable for its danger: at times, it has challenged Bennu at the top of the league table of most dangerous objects. But recent research has suggested that Apophis poses less of a danger. Ashley King, UKRI future leaders fellow, Natural History Museum, said: “Osiris-Rex spent over two years studying asteroid Bennu, finding evidence for organics and minerals chemically altered by water. “These are crucial ingredients for understanding the formation of planets like Earth, so we’re delighted to be among the first researchers to study samples returned from Bennu. ‘We think the Bennu samples might be similar in composition to the recent Winchcombe meteorite fall, but largely uncontaminated by the terrestrial environment and even more pristine.” Dr Sarah Crowther, research fellow in the Department of Earth and Environmental Sciences at the University of Manchester, said: “It is a real honour to be selected to be part of the Osiris-Rex sample analysis team, working with some of the best scientists around the world. “We’re excited to receive samples in the coming weeks and months, and to begin analysing them and see what secrets asteroid Bennu holds. “A lot of our research focuses on meteorites and we can learn a lot about the history of the solar system from them. “Meteorites get hot coming through Earth’s atmosphere and can sit on Earth for many years before they are found, so the local environment and weather can alter or even erase important information about their composition and history. “Sample return missions like Osiris-Rex are vitally important because the returned samples are pristine, we know exactly w Read More Pieces of a distant asteroid are about to fall to Earth Nasa to return largest asteroid sample ever as UK helps with research Astronomers find abundance of Milky Way-like galaxies in early universe Pieces of a distant asteroid are about to fall to Earth Nasa to return largest asteroid sample ever as UK helps with research Astronomers find abundance of Milky Way-like galaxies in early universe

Mitt Romney’s blistering response to Trump’s damning indictment
Mitt Romney’s blistering response to Trump’s damning indictment
Republican US Senator Mitt Romney said that former president Donald Trump had brought an indictment upon himself for his taking classified documents and refusing to return them. Mr Romney released a statement on Friday after news that a grand jury indicted Mr Trump for his alleged unlawful of retention of national defence information at his Mar-a-Lago estate. Mr Trump said he must report to a court in Miami by Tuesday at 3pm ET. “Like all Americans, Mr Trump is entitled to the presumption of innocence. The government has the burden of proving its charges beyond a reasonable doubt and securing a unanimous verdict by a South Florida jury,” Mr Romney said. “By all appearances, the Justice Department and special counsel have exercised due care, affording Mr Trump the time and opportunity to avoid charges that would not generally have been afforded to others,” he said. “Mr Trump brought these charges upon himself by not only taking classified documents, but by refusing to simply return them when given numerous opportunities to do so.” The 2012 Republican presidential nominee, whom Mr Trump endorsed in that election, has since emerged as one of the GOP’s most outspoken critics of the former president. Mr Romney voted to convict Mr Trump in his first impeachment trial in 2020, the only Republican Senator to do so, for attempting to withhold aid for Ukraine in exchange for Ukrainian President Volodymyr Zelensky investigating Joe Biden’s son when Mr Trump was running for re-election. In 2021, six other Republicans joined Mr Romney to convict Mr Trump for his incitement of the January 6 riot. Mr Romney alluded to those cases in his statement. “These allegations are serious and if proven, would be consistent with his other actions offensive to the national interest, such as withholding defensive weapons from Ukraine for political reasons and failing to defend the Capitol from violent attack and insurrection,” he said. The statement stands in contrast to Mr Romney’s statement after a New York grand jury indicted Mr Trump in April, when Mr Romney expressed some scepticism. New York County District Attorney Alvin Bragg’s office charged Mr Trump on 34 counts related to his allegedly making hush money payments to adult film actress Stormy Daniels. “Even so, I believe the New York prosecutor has stretched to reach felony criminal charges in order to fit a political agenda,” Mr Romney said at the time. “No one is above the law, not even former presidents, but everyone is entitled to equal treatment under the law. The prosecutor’s overreach sets a dangerous precedent for criminalizing political opponents and damages the public’s faith in our justice system.” Read More Trump-appointed judge will initially preside over ex-president’s federal court appearance Trump indictment — live: Trump’s brazen classified document admission revealed amid MAGA meltdown over charges Jailhouse Rock?
