Chinese rocket that hurtled into the Moon was carrying a ‘secret object’
Chinese rocket that hurtled into the Moon was carrying a ‘secret object’
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."

Science has determined what the optimum length of time we should spend in a bath
Science has determined what the optimum length of time we should spend in a bath
There's nothing better than a hot bath to warm up and unwind on a chilly winter evening - but water bills don’t come cheap, so it’s more important than ever to make sure you’re making the most of your time in the tub. So how long should we be spending in the bath? Well, a recent study has uncovered that 22 minutes is the optimum length of time to spend in the bath. The study conducted by Victorian Plumbing sought to discover ULTIMATE bath time for relaxation, hydration and a good night’s sleep. There were 20 participants involved in the experiment - half male and half female - who took baths of varying lengths and rated how they felt afterward based on a number of factors. The study concluded that 22 minutes is the optimum amount of time to spend in the tub - to feel relaxed, hydrated, and sleep well after. Soaking should stop at 27 minutes if you don’t want to stay feeling hydrated post-bath, according to the study. This supports the advice of some professionals, who suggest that baths should be no longer than 30 minutes. It was also uncovered that baths impact men and women slightly differently. Women have a better night’s sleep after a longer bath, ideally, 30 minutes long, whereas men sleep better after 19 minutes. Those who felt more relaxed after the baths had scrolled on their phone during their time in the tub, whereas those who watched TV were found to be the least. Sorry to burst your bubble bath lovers, but the findings also suggest that people who take more baths are generally more stressed - although they find them more relaxing than shower- on the whole. “When the nights start getting colder in the UK, we tend to see an increase in Brits looking to buy a bath. And who can blame them? There are a number of benefits of a bath; they’re soothing, and cleansing and studies have even suggested that there are similar benefits to exercise," Brenna Ryan from Victorian Plumbing said about the study's findings. “To help you get the most out of your bath, we conducted a study which found that the optimum time to spend in the tub is 22 minutes - to leave you feeling relaxed, hydrated and sleep like a baby.” How to join the indy100's free WhatsApp channel Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
