A number of startups have emerged aimed at cleaning up low Earth orbit, which is currently crowded with millions of pieces of space junk — including anything from broken satellites, to rocket fragments, to debris from vehicle stages or space missions.While the task of cleaning up LEO is an important one, there’s one problem, according to Alex Fielding, co-founder of a new space venture alongside Steve Wozniak: We don’t know where most of the space junk is actually located.“Orbital cleanup companies, they don’t have resolution, or we don’t agree on where almost any object in low Earth orbit is with greater accuracy than maybe three or 400 kilometers on any given moment,” Fielding said in a recent interview with TechCrunch.The company, which has been in stealth, got some attention in September after Wozniak tweeted a link to a one-minute promo video on YouTube, and rumors intensified that Privateer would be focused on cleaning up space objects.“You’re in a world with many, many, many more things [in orbit], of which those many more things are far more dangerous, they’re almost all in low orbits, they’re moving very, very fast, and they’re not well tracked or understood for the most part.”The dangers of space junk remain all too present."
