CNN —Two stubborn fasteners trapped invaluable material sampled from an asteroid — but after a monthslong process, it has finally been released, NASA announced Thursday. The space agency already harvested about 2.5 ounces (70 grams) of rocks and dust from its OSIRIS-REx mission, which traveled nearly 4 billion miles to collect the unprecedented sample from the near-Earth asteroid called Bennu. But NASA revealed in October that some material remained out of reach in a capsule hidden inside an instrument called the Touch-and-Go Sample Acquisition Mechanism — a robotic arm with a storage container at one end that collected the sample from Bennu. The sampler head is held shut by 35 fasteners, according to NASA, but two of them proved too difficult to open. What the asteroid sample has revealed so farAs of Thursday afternoon, NASA said the trapped sample material had not yet been revealed.
