Will NASA’s OSIRIS-REx stick its asteroid sample landing? Scientists are ‘very much confident’ as zero hour nears

It’s the final countdown. 

NASA’s $1 billion OSIRIS-REx sample return mission is less than 48 hours away from its dramatic landing in the Utah desert. The OSIRIS-REx spacecraft (which stands for “Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer”) is currently heading toward Earth while carrying precious cargo: A capsule containing somewhere around 8.8 ounces (250 grams) of material gathered from asteroid Bennu in 2020.
