OSIRIS-REx: A Journey to Asteroid Bennu and Back

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) is the first U.S. mission to collect a sample from an asteroid and return it to Earth. Launched on September 8, 2016, the spacecraft arrived at asteroid Bennu in December 2018 and collected a sample from its surface on October 20, 2020. The mission aims to deliver the largest asteroid sample ever received on Earth, estimated to hold about half a pound of Bennu’s material or 8.8 ounces +/- 3.6 ounces (250 grams +/- 101 grams).

Press Release: Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b (STSI 2023)

Data hints at exoplanet possessing possible liquid ocean surface
Carbon-bearing molecules have been discovered in the atmosphere of the habitable zone exoplanet K2-18 b by an international team of astronomers using data from the NASA’s James Webb Space Telescope. These results are consistent with an exoplanet that may contain ocean-covered surface underneath a hydrogen-rich atmosphere. This discovery provides a fascinating glimpse into a planet unlike anything else in our Solar System, and raises interesting prospects about potentially habitable worlds elsewhere in the Universe.
