China did almost the same thing a few weeks ago!!<br /><br /><br />ROCKET EXPLOSION: Australian astronomer Ray Palmer was photographing the Southern Cross from his observatory in Western Australia on Feb. 19th when a flaming plume cut across the Milky Way. "I had no idea what it was," he says. "It was moving very slowly and I was able to track it for 35 minutes." <br /><br /><br />Photo details: Nikon FM2, 50mm lens, Kodak Elite Chrome 200, 30 minutes. <br /><br />In mid-apparition the object exploded. Gordon Garradd of New South Wales photographed an expanding cloud filled with specks of debris. Tim Thorpe of South Australia saw it, too. "Quite a surreal scene," he says. <br /><br />What was it? It was a mystery for almost 24 hours until satellite expert Daniel Deak matched the trajectory of the plume in Palmer's photo with the orbit of a derelict rocket booster--"a Briz-M, catalog number 28944." <br /><br />One year ago, the Briz-M sat atop a Russian Proton rocket that left Earth on Feb. 28, 2006, carrying an Arabsat-4A communications satellite. Shortly after launch, the rocket malfunctioned, leaving the satellite in the wrong orbit and the Briz-M looping around Earth partially-filled with fuel. On Feb. 19, 2007, for reasons unknown, the fuel tanks ruptured over Australia. <br /><br />Jon P. Boers of the USAF Space Surveillance System confirms the ID and notes "later, on the other side of the world, our radar saw 500+ pieces in that orbit." Today the count is up to 1111 fragments. "[We're seeing] more fragments as the cloud expands," he explains. <br /><br />Some of the fragments are visible in this movie made by Rob McNaught at the Siding Spring Observatory, NSW, Australia: <br /><br /><br />Photo details: Canon 5D, 50mm lens, f/1.4, 20 x 20sec exposures. <br /><br />"Spica is at the right edge of the animation and the fragments are moving to the north and east," he says. <br /><br />One thousand-plus fragments makes this "a major breakup event," says Mark Matney of NASA's Orbital Debr
