Tagging Bennu

APOD: 2023 September 21 - Tagging Bennu Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 September 21 Tagging Bennu Image Credit: OSIRIS-REx, University of Arizona,NASA, Goddard Scientific VisualizationStudio Explanation: The OSIRIS-REx spacecraft's arm reached out and touched asteroid 101955 Bennuon October 20, 2020,after a careful approach tothe small, near-Earth asteroid's boulder-strewn surface.Dubbed aTouch-And-Go(TAG) sampling event, the 30 centimeter widesampling head (TAGSAM) appears to crush some of the rocks in thisclose-up recorded by the spacecraft's SamCam.The image was snapped just after surface contactsome 321 million kilometers from planet Earth.One second later, the spacecraft fired nitrogen gasfrom a bottle intended to blow a substantial amount ofBennu's regolithinto the sampling head, collecting theloose surface material.And now, nearly three years later, on Sunday, September 24,that sample of asteroid Bennu is scheduled toarrive on planet Earth.The sample return capsule will be dropped off by the OSIRIS-Rexspacecraft as it makes a close flyby of Earth.Twenty minutes after the drop-off, the spacecraft will fire itsthrusters to divert past Earth and continue on to orbit near-Earthasteroid 99942 Apophis.

Cosmos in Reflection

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 September 21 Cosmos in Reflection Image Credit &Copyright:Jeff Dai(TWAN) Explanation: During the day,over 12,000 large mirrors reflectsunlight at the 100-megawatt, molten-salt, solar thermal power plant at thewestern edge of the Gobi desert nearDunhuang, Gansu Province, China.Individual mirror panels turn to track the sun like sunflowers.They conspire to act as a single super mirror reflectingthe sunlight toward a fixed position,the power station's central tower.During the nightthe mirrors stand motionless though.They reflect the light of the countless distant stars,clusters and nebulae of the Milky Wayand beyond.Thissci-finight skyscape was created with a camera fixedto a tripod near the edge of the giant mirror matrix onSeptember 15.The camera's combined sequence of digital exposures capturesconcentric arcs of celestialstar trails through the nightwith star trails insurreal mirrored reflection.
