Mars helicopter Ingenuity performs well before first flight

Science
April 7 (UPI) -- NASA's Mars helicopter Ingenuity, the first powered aircraft on another planet, is free of the Perseverance rover that carried it and appears to be functioning well ahead of its first flight on Sunday, the space agency said. NASA plans to broadcast the results of that first flight at 3:30 a.m. EDT Monday after the helicopter transmits data and images to Perseverance, which will send them back to Earth. Advertisement The helicopter detached from the rover's underbelly Saturday and survived subzero temperatures with its own heaters, which NASA said was "a major milestone" in an announcement Tuesday. The 4-pound rover uses solar panels to charge its batteries and keep delicate electronics safe from extreme cold that can reach 130 degrees F below zero. "So far, everything ha...

The tests are part of SpaceX's rapid prototype development methods, which the company used to develop its highly successful Falcon rockets.

Liverpool score 7,000th top flight goal as they end losing run in Premier League with triumph over Sheffield United

Sports
It’s too early to say if Liverpool are back in business but a 2-0 win at Sheffield United will make Jurgen Klopp and Co. feel a whole lot better. They went into the Bramall Lane clash having lost their last four matches in the Premier League but they had no such problems on Sunday night. AFP Roberto Firmino and Curtis Jones set Liverpool on their way for the win Curtis Jones slotted in the opener just after the break while a Roberto Firmino effort, which took a sizeable deflection off Kean Bryan, sealed the three points. Liverpool’s second goal was actually their 7,000th in top flight matches on a night where they could have had more but for the brilliant goalkeeping of Aaron Ramsdale. Ramsdale saved efforts to deny Firmino, Andy Robertson, Moha...
Mystery of butterfly flight finally cracked by scientists

Mystery of butterfly flight finally cracked by scientists

Technology
Scientists believe they have finally cracked the mystery of how butterflies fly despite their "unusually short, broad and large wings" compared to their body size.A new study published in the Journal of the Royal Society finds that the key is not in the downstroke, when the butterflies' wings push them forward, but in the upstroke when the wings clap together. "When the wings clap together at the end of upstroke the air between the wings is pressed out, creating a jet, pushing the animal in the opposite direction," the researchers say.[embedded content] The theory about wing claps to explain butterfly flight was first proposed in the 1970s but has only just been proven by Swedish scientists at Lund University.The researchers caught six wild butterflies in the meadows around Stensoffa, in ...
