NASA's Struggle to Open Canister Holding Asteroid Sample

NASA is facing difficulties in opening the canister containing the asteroid sample collected by the OSIRIS-REx spacecraft. While scientists have managed to collect rock and dust from outside the canister, the bulk of the sample remains stuck inside. The team at NASA's Johnson Space Center has been struggling to open the sampler head, where the majority of the sample is located. They are working on developing new approaches to extract the material while ensuring its safety and integrity. Despite the challenges, the mission has already exceeded its goal of collecting 60 grams of debris, recovering 70.3 grams of rocks and dust.
