A mysterious object crashed into the Moon last year, and scientists think they’ve finally figured out what it was. On March 4, 2022, a piece of space junk hurtled towards the surface of our celestial companion, leaving behind not one but two craters – prompting speculation as to what exactly the manmade object was. And now, in a paper published in the Planetary Science Journal, a team of researchers at the University of Arizona (UArizona) have offered “definitive proof” that it was a booster from a Chinese space rocket that had spent several years hurtling through space. But the most interesting part of all this? The defunct piece of spacecraft was apparently carrying a secret cargo. Initially, based on its path through the sky, the UArizona team thought it was an errant SpaceX Falcon 9 rocket booster from a 2015 launch. However, after analysing how precise light signals bounced off its surface, they later concluded that it was more likely to be a booster from a Chang'e 5-T1 – a rocket launched back in 2014 as part of China’s lunar exploration programme. And yet, the Chinese space agency denied ownership, insisting that their rocket booster burned up in the Earth's atmosphere upon re-entry. But the US Space Command refuted this claim by revealing that the rocket’s third stage never re-entered the planet’s atmosphere. Furthermore, two key pieces of evidence gathered by the UArizona researchers suggested that there was more to the object than just a simple abandoned rocket booster. Firstly, the way it reflected light. The paper’s lead author, Tanner Campbell, explained in a statement: "Something that's been in space as long as this is subjected to forces from the Earth's and the moon's gravity and the light from the sun, so you would expect it to wobble a little bit, particularly when you consider that the rocket body is a big empty shell with a heavy engine on one side. “But this was just tumbling end-over-end, in a very stable way." In other words, the rocket booster must have had some kind of counterweight to its two engines, each of which would have weighed around 545kg (1,200lbs) without fuel. The stability with which the object rotated led Campbell and his colleagues to deduce that “there must have been something more mounted to [its] front”. Secondly, the team were struck by the impact the booster left when it slammed into the Moon. It created two craters, around 100ft (30.5 metres) apart, instead of one, which, according to Campbell was very unusual. He pointed out that the craters left behind by Apollo rockets are either round, if the object came straight down, or oblong if it crashed down at a shallow angle. "This is the first time we see a double crater," he said. "We know that in the case of Chang'e 5 T1, its impact was almost straight down, and to get those two craters of about the same size, you need two roughly equal masses that are apart from each other." And yet, despite the rigour of their investigation, the UArizona team have been unable to identify what exactly this additional object was. "We have no idea what it might have been – perhaps some extra support structure, or additional instrumentation, or something else," Campbell admitted. "We probably won't ever know."

LAUSANNE, Switzerland & NEWARK, Calif.--(BUSINESS WIRE)--May 24, 2023--

Amazon says it will soon start using drones to drop packages into people’s gardens from the air in the UK. Customers will be able to make orders and then have Amazon load their packages into autonomous aircraft at its fulfilment centres, the company said. Those drones will then fly to their house, and drop the package into the garden from the air, doing so within 60 minutes, it said. For customers, the drones will be offered alongside the usual set of delivery options, and for no extra price. The deliveries are intended to sit alongside traditional deliveries for when people want small items such as suncream or Fire Sticks quickly, Amazon said. The drones should be launched from new locations by the end of 2024, Amazon said as part of a host of announcements for its plans for Prime Air, its drone delivery arm. It also announced a new drone, which it calls the MK30, which it says is quieter and able to operate in more diverse conditions, such as light rain. Like the existing drones, those new ones are capable of carrying one, 5lb package in a dedicated storage container built into the drone. The package is then ejected out of that container when the drone arrives at the delivery point, which will generally be in customers’ gardens. Amazon stressed that it had looked to build the drones with safety features such as the ability to spot any obstacles, seemingly in an attempt to allay concerns about the danger they may pose, especially in suburban areas. The drone includes technology that will stop deliveries if it spots a pet in the drop-off area, for instance. The drones then fly themselves back to their base, and land vertically just as they take off, on the stands from which they are launched. They can then have their batteries swapped for the next launch. Amazon has already launched drone delivery in two locations in the US, in Texas and California. It says those projects have delivered “thousands” of packages in the last 12 months since those projects launched. But it will now launch a similar scheme in the UK, as well as in Italy and at another US location, by the end of 2024. It has not said exactly where those drones will fly from, but suggested that it will do so soon. The drones will be able to fly out to about 12 kilometres from their base, which will be located in one of the UK’s fulfilment centres. The location has been chosen and will be announced in a “couple of months”, he said. The company intends to expand the rollout after that, however, with Amazon’s head of Prime Air telling The Independent that there is a “mapped-out plan” to open more facilities over time. “This is not a market test,” he said. That is part of a plan to increase deliveries from thousands now to hundreds of millions by the end of the decade. “Our vision for a successful delivery solution for our customers, who really want their packages faster, is to be able to deliver 500 million packages by the end of the decade to customers in highly-populated, dense urban areas,” Mr Carbon said. Mr Carbon said that Amazon had chosen the UK for its next expansion in recognition of its aerospace heritage, as well as Amazon’s large footprint in the country and high demand from customers. He also said that Prime Air had a “great legacy” in the country, with the first ever successful Amazon drone delivery happening in Cambridge in 2016, though its operations have been scaled back in the country since. Showing off Amazon’s work on drones to reporters in Seattle, Mr Carbon said that much of the recent work had gone into safety features, and he said the new drones were certified in the same way as traditional planes. Amazon’s current drones are twice as safe as driving to a physical store to pick up an item, he said, and the upcoming MK30 is “two orders of magnitude” safer than making that journey. He suggested that part of the reason for expanding the drone network was to reduce the number of cars making deliveries in busy cities, as well as reducing the need for panicked and potentially unsafe journeys to shops when people need ultra-fast deliveries. But he also said that there was “absolutely” a demand for such quick deliveries from customers. It was clear that customers “want stuff fast”, he said. Amazon is “committed to taking technology, finding technology, developing technology” to make the experience of deliveries better in response, he said. Amazon has not said how much the drone project has cost in the more than a decade it has been in operation. It also would not say exactly how many drones are in its fleet, or give any information the economics of the flights, such as how many deliveries would be required for it to be profitable. But he did stress that the new rollout is “not about proving that you can deliver a package by drone” and is not a pilot or a test scheme, but a real rollout of the technology with a view to making it widespread. He did say however that it would “start slow” to increase the chances of success. The UK has its own regulatory framework, and Amazon said it had been working with regulators and the government to ensure the drones are ready to launch by the end of next year. But it also comes with its own challenges, such as dense urban areas, fewer gardens and less use of the grid system that can make US neighbourhoods easier to map. Mr Carbon said that Amazon had designed the drone and the other systems that support its journeys to be able to do so in a range of different environments. The drone “has been designed to cope with where our customers are”, he said. Amazon was unable to say what restrictions it expected regulators to put on the drones’ flights, such as weather they would be allowed to cross roads and whether someone would need to have sight of it at all times. It said that it was working on technologies to give the drones more capabilities – such as the ability to autonomously spot and avoid obstacles – with the hope that those would allow for less restrictions. UK regulator the Civil Aviation Authority suggested that Amazon’s work would lead to changes such as the ability for commercial flights to operate without being watched by their pilot. “Exploring the options of how drones can be safely and successfully incorporated into more of the UK’s airspace is key,” Frederic Laugere, head of innovation advisory services at the UK Civil Aviation Authority. “It is vital that projects such as this take place to feed into the overall knowledge and experiences that will soon enable drones to be operating beyond the line of sight of their pilot on a day-to-day basis, while also still allowing safe and equitable use of the air by other users.” The new locations are just one part of a plan to bring the deliveries to “as many Amazon customers as our technology can safely enable”, Amazon said in its announcement. It plans to “soon” launch from “new cities, countries, and continents”, it said.

A recent study has found that eating strawberries daily could reduce the risk of developing dementia. Researchers at the University of Cincinnati claim that by eating the fruit every day, certain people of middle age could reduce their risk of dementia. The 12-week study published in Nutrients had 30 overweight patients - who had complained of mild cognitive impairment - abstain from eating berries, aside from a daily packet of supplement powder mixed with water and consumed with breakfast. Half of the participants, who were 50 to 65 years old, received a powder that contained the equivalent of one cup of whole strawberries (the standard serving size), whilst the other half received a placebo. Participants' long-term memory, mood, and metabolic health were measured by researchers. The team found that those who had taken the strawberry powder had performed better on a wordlist learning test, as well as having a significant reduction in depressive symptoms. "Both strawberries and blueberries contain antioxidants called anthocyanins, which have been implicated in a variety of berry health benefits such as metabolic and cognitive enhancements," said Robert Krikorian, professor emeritus in the UC College of Medicine's Department of Psychiatry and Behavioural Neuroscience. "There is epidemiological data suggesting that people who consume strawberries or blueberries regularly have a slower rate of cognitive decline with ageing." Ellagitannins and ellagic acid are also found in strawberries, which are known to possess anti-inflammatory, antioxidant, antimicrobial, and anticancer properties. Krikorian went on to explain that strawberries may have improved cognitive function by reducing inflammation in the brain. "Executive abilities begin to decline in midlife and excess abdominal fat, as in insulin resistance and obesity, will tend to increase inflammation, including in the brain," he explained. The university did, however, acknowledge that Krikorian's research was partly funded by the California Strawberry Commission. Although said that the group had no role in the design of the study, data collection and analysis, or publication of the results.
