NASA has lifted the lid on its first findings about the Bennu sample, one of the "most hazardous known asteroids". The highly-anticipated sample from the OSIRIS-REx’s mission took seven years to complete and finally made a safe landing on Sunday 24 September. Scientists audibly gasped upon opening the capsule. They kept details to a minimum and maintained a slow pace in progress for "good reason," as they received more material than expected. "The abundance of material found when the science canister lid was removed earlier this week has meant that the process of disassembling the TAGSAM (Touch-and-Go Sample Acquisition Mechanism) head – which holds the bulk of material from the asteroid – is off to a methodical start," they said a the time. That was until now... On Wednesday 11 October, the space agency shared details for the first time from NASA experts and the University of Arizona. NASA said there were signs of water and carbon on the sample through hydrated clay minerals that contain carbon. "At nearly 5% carbon by weight, carbon being the central element of life, far exceeding our goal of 60g, this is the biggest carbon-rich asteroid sample ever returned to earth," Administrator Bill Nelson said, adding that it was "exactly the kind of material that we wanted to find." He went on to suggest that "they are going to help us determine the origin of elements that could have led to life" and provide a greater understanding of how to protect Earth from asteroids. Scientists also revealed that the sample contained space dust from asteroid Bennu. NASA showed the audience the sample on a video to protect the sample and to prevent contamination. Speaking about working through a glove box to analyse the sample, Francis McCubbin, astronomical curator at NASA's Johnson Space Centre said: "[It is] "hard, challenging work, and it does not go quickly, but we need to do this right". The samples will be preserved so that "scientists that aren't even born yet are going to have the opportunity to answer questions about our universe with these samples using technology that has not even been invented."

A BA flight was diverted back to the UK amid security concerns, not long before it was due to land.

Yamaha has unveiled a self-riding electric motorbike that features no handlebars or other standard controls. The Yamaha Motoroid 2 is the next generation of the firm’s Motoroid concept bike first revealed in 2017, but unlike its predecessor, Yamaha has built a working prototype of the latest vehicle. The self-balancing bike features gyroscopes and image recognition AI systems to stay upright and navigate roads, while also being capable of riding itself without anyone aboard. “Motoroid 2 is a vehicle for personal mobility that can recognise its owner, get up off its kickstand and move alongside its rider,” the company said. “[It] has a distinctly lifelike feel when somebody is riding on its back and has a presence more like a lifetime companion.” Yamaha plans to show off the prototype of the Motoroid 2 at the Events Japan Mobility Show 2023 in Tokyo next month. It is not clear whether Yamaha plans to release a production model of the bike, however its continued development suggests that the automotive giant is working to integrate at least some of its features into future motorcycles. Self-driving technology is increasingly common in production vehicles, though it is currently limited to four-wheeled cars and trucks. Some have even considered eschewing steering wheels, with Tesla chief executive Elon Musk originally planning to build a fleet of self-driving electric taxis that have no visible user controls. The plan was reportedly sidelined after company executives noted that regulators in most major markets require steering wheels and pedals on vehicles. Several motorcycle manufacturers have unveiled concept bikes that require no rider to operate. BMW’s ConnectedRide retrofits the company’s R 1200 GS Adventure with autonomous technology to serve as a “testbed for advanced motorcycle safety” equipment that it hopes to introduce to its production models. “In a future world of autonomously driving cars, being connected will be an urgent requirement for all motorcycle segments,” BMW’s Markus Schramm said in 2020. “This will enhance safety and ensure that motorcycling remains future-proof.” Read More Reinventing the seatbelt for the self-driving era

Mysterious blasts coming from deep in space could be the result of “starquakes”, according to a new study. For years, scientists have been observing fast radio bursts, or FRBs, coming from distant parts of space. They are very intense, very short blasts of energy – and despite finding many of them, researchers still do not know where they are coming from or how they might be formed. Now, scientists have spotted that there is appears to be similarities between those FRBs and earthquakes. Researchers behind the new study suggest that the blasts could be the result of similar behaviour on neutron stars, known as starquakes. It is just one possible explanation for the unusual bursts, which have led to suggestions they could be anything from neutron stars colliding with black holes to alien technology. Most have settled on the belief that at least some of those FRBs come from neutron stars, however, which are formed when supergiant stars collapse into an incredibly dense, small object. In the new study, researchers looked at data from nearly 7,000 bursts, taken from three different sources that are sending out repeated FRBs, examining the time and energy that they emerged in. They then also looked at earthquake information taken from Japan, and data on solar flares, and looked to compare the three. There was little connection between FRBs and solar flares, the researchers found. But there was a striking similarity between the blasts and earthquakes. “The results show notable similarities between FRBs and earthquakes in the following ways: First, the probability of an aftershock occurring for a single event is 10-50%; second, the aftershock occurrence rate decreases with time, as a power of time; third, the aftershock rate is always constant even if the FRB-earthquake activity (mean rate) changes significantly; and fourth, there is no correlation between the energies of the main shock and its aftershock,” said Tomonori Totani from the University of Tokyo, one of the leaders of the study. The findings have led scientists to speculate that there is a solid crust on the outer surface of neutron stars. That crust then experiences starquakes in the same way the Earth’s surface does – and those quakes then let out powerful blasts of energy that make their way to us as FRBs. But researchers say they will need to further examine those FRBs to better understand the connection between the two – as well as to help give us information about quakes and other physical phenomena that are closer to home. “By studying starquakes on distant ultradense stars, which are completely different environments from Earth, we may gain new insights into earthquakes,” said Professor Totani. “The interior of a neutron star is the densest place in the universe, comparable to that of the interior of an atomic nucleus. “Starquakes in neutron stars have opened up the possibility of gaining new insights into very high-density matter and the fundamental laws of nuclear physics.” The research is described in a new paper, ‘Fast radio bursts trigger aftershocks resembling earthquakes, but not solar flares’, published in the journal Monthly Notices of the Royal Astronomical Society.
