Scientists have gathered a significant chunk of a distant asteroid, which has made its way to Earth after a mission taking millions of miles. But the really useful work will begin now. Nasa’s Osiris-Rex mission flew to the distant Asteroid Bennu, scooped up a piece of the object into a canister, and then flew back to Earth to drop it off. On Sunday, Nasa picked up that canister in the Utah desert and is now working to secure it. It will then send those samples to a variety of scientists around the world, with a chunk of it being sent to more than 200 people at 38 different institutions across the world. They hope that they can use them as a “time capsule” to peer into the early universe, telling us about where we came from. “This box when it is opened of material from the surface of Bennu can tell us untold secrets of the origins of the universe, the origins of our planet and the origins of life itself,” said Queen musician Brian May, who helped with the research by mapping out the asteroid to find a landing spot. “What an incredibly exciting day.” Sample return missions are particularly exciting to scientists because they offer a look at a pristine piece of a distant world that has been undisturbed by the environment on Earth. While some pieces of asteroids and other objects can fall down to Earth, they have to make their way through the atmosphere and can be damaged and changed in the process. They also mean that researchers are able to use all of the Earth’s latest technology to study the sample. Other pieces of distant worlds have of course been studied by spacecraft and landers, but they are only able to do so with the limited instruments they take to those planets. Another advantage of sample return missions over studying the objects at their home is that scientists can look back at those samples with new sensors and equipment invented long after the sample was actually taken. Many space missions continue for years – Curiosity is still examining Mars after arriving there in 2012, and the Voyager probes are still providing information almost 50 years after they were launched – but they are only able to do so with the technology that was available when they set off. The analysis done in sample return missions really begins when the spacecraft arrives at its target: then, it starts looking at the context of the sample, gathering information about the world from which it came that should prove useful to scientists later. Osiris-Rex arrived at Bennu in 2018, and spent two years mapping the asteroid before it set off back home with its delivery. All of that information in addition to the samples could help answer a variety of questions about our planet, scientists hope. “The asteroids in our solar system contain the raw building blocks from which the Earth was made, so working out their composition will tell us a lot of how our planet formed,” said Boris Gansicke from the department of physics at the University of Warwick. “There are many open questions, for instance, where did the water that we have on Earth come from? And where did the ingredients that made life possible to develop come from? “To answer those questions, ie measure the composition of an asteroid, you need to get your ‘hands’ on them (or in this case the arm of a space mission), and this is what Osiris-Rex achieved. “In a nutshell, it’s similar to sitting in front of a delicious dinner and wanting to have the list of ingredients.” Sample return missions are almost as old as space travel itself, and the first of them were the early Apollo missions, which brought back pieces of the Moon. Those continue to be useful to scientists. Since then, as human travel into space has declined, most of the work has been done by robots. In the early 1970s, the Soviet Union’s Luna missions gathered pieces of the Moon and brought them back, and in 2020 Japan’s Hayabusa2 mission brought back pieces of the asteroid Ryugu. Scientists have high hopes for future missions: perhaps the most discussed is a mission to Mars, which would bring back the first ever pieces of that planet. Engineers have suggested that for decades, and a number of plans have been formed, but none are likely to launch any time soon.

Whether your child’s GCSE results are high, low, or somewhere in between, one thing is inevitable – they’ll compare them with their friends’ grades. This comparison culture, which is far more pervasive because of social media, can leave teens feeling inadequate because their results are worse than their mates, or make their friends feel useless if roles are reversed. But although there’s no getting away from teenagers comparing their results both on and offline, what can parents do to try and limit the damage this it can cause? Former teacher Dr Julia Clements, principal educational psychologist at the children’s mental health charity Place2Be, says the comparison of results will undoubtedly impact some teenagers’ wellbeing. “Your teenager is bound to compare their results with their peers at the same school, but also through social media,” she acknowledges. “Although this comparison is inevitable, it may be harmful for your child’s wellbeing – especially if they’ve not done as well as expected. “Indeed, the term ‘compare and despair’ can be especially pertinent on days like today.” Sharon Davies, CEO of Young Enterprise, a charity which helps young people navigate the changing world of work, adds: “The pressure to measure up to their friends’ achievements can be overwhelming, leading to feelings of inadequacy or disappointment.” So how can parents help their teens? 1. Ask how they feel If your child is down on themselves and rating themselves negatively in comparison to their friends, they may reject any positives and praise parents provide, Clements warns. “It may be more useful, in the first instance, to ask them how they’re feeling, and to acknowledge and validate difficult feelings,” she advises. Such feelings may include disappointment, sadness, anger, shame, or feeling as if they’ve let themselves – and you – down. “If your child is feeling like this, it’s important to give them the message that you love them unconditionally and you’re proud and pleased to be their parent because of who they are – not because of the grades they achieve,” she stresses. 2. If they’ve done better than their friends… If your child has achieved good results, which may be better than some of their friends, then they’ll want to celebrate. But while celebrating is of course a great idea, Clements suggests: “You may want to talk with them about how to be sensitive and compassionate towards their friends who haven’t done so well.” 3. Help them turn a negative into a positive Consultant clinical psychologist Dr Nihara Krause specialises in teenage mental health and is working with the Talking Futures campaign to help parents engage their children in meaningful conversations about their futures. She says if a young person doesn’t get the grades they were hoping for, they may be highly critical of their performance in comparison to their peers. But she suggests parents show them how to turn their negative thinking around. “Parents should encourage their children to focus on recognising the approach they took to exams this time round and take steps to reflect on what they could do to achieve a better result in the future. Focus on what helps a young person gain their own personal best, no matter how their results compare with others.” 4. Don’t ask about their friend’s results or post about them Krause says parents should try to celebrate their child’s achievements for what they are and avoid asking about their friends’ results. “To avoid comparison, parents should also avoid sharing their child’s results on social media,” she says. 5. Don’t be too hard on yourself Clements points out that comparison culture may not just affect teenagers – if their results aren’t as good as expected, mums and dads might start comparing their own parenting during the revision and exam period with other parents whose kids have got better results. “As a parent or carer, you may also be drawn into unhelpful comparisons with others,” says Clements, “and you may question the amount of support you were able to provide your child in the run up to their exams. However, today is not a day for self-criticism or judgements – some self-compassion is important at this time.” 6. Reach out for support This might be the first results day many parents have gone through with their child, and while comparisons with other teens may well have been unhelpful, Davies points out that schools will have career advisers and teachers available who can offer support and advice. There are also online forums and blogs where those in similar situations share their experiences. She says: “No-one is expecting you to have all the answers – that’s why there’s support available.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Women more severely affected by ME, study claims 4 hacks to get teens off the sofa and get active – as study warns of heart damage Taking adult education classes may lower risk of dementia, study suggests
