Our First Asteroid Sample Return Mission is Back on Earth on This Week NASA

That's exciting news! As of my last knowledge update in September 2021, NASA had several asteroid sample return missions in progress, including OSIRIS-REx, which was expected to return with a sample from the asteroid Bennu in 2023. If you're referring to OSIRIS-REx or another mission that has returned with an asteroid sample, it's a significant milestone in our exploration of space and the study of these celestial bodies.

I recommend checking NASA's official website and recent news updates for the latest information on the mission's successful return and any scientific findings they have made from the asteroid sample. NASA typically provides detailed information and updates about their missions on their website and through press releases.
