9:04pm ET -- September 22, 2022 Happy Equinox to all residents of Planet Earth. In the N. Hemisphere, summer ends -- the longest of the four seasons: checking in at 93 days, 15 hours. Over that time, Earth orbits farther from the Sun, traveling more slowly than average.

Today marks the September equinox – the #FirstDayOfFall in the Northern Hemisphere and the first day of spring in the Southern Hemisphere – which occurs when both hemispheres see equal amounts of daylight: https://t.co/tvxoSjONUf How do you mark the changing seasons? https://t.co/pefGlH8Iyn

Family photo time! #OTD in 2014, the Cassini spacecraft took this rare image of 3 of Saturn’s 82 moons: Tethys (the big guy), Hyperion (the mini-potato left of Tethys) and Prometheus (lower left at the edge of the F ring).

Live: Join senior leaders from NASA and @JHUAPL working on the #DARTMission, the world's first test of planetary defense. Preview mission milestones between now and impact with a non-threatening asteroid on Sept. 26. https://t.co/Icq23Hb49a

I thought this sub would enjoy this app - its a free app called ISS Live. I received some good feedback on this and I wanted to share. You can expand to see the Earth in the entire screen. Sunrises and sunsets are really to watch.

Crashing into an asteroid is complex work! @NASA’s #DARTMission will impact a small, non-threatening moonlet to test technology that could defend Earth against potential future hazards. Our JPL team is working with @JHUAPL to make it happen. 🤝 More: https://t.co/vyqnhAd2Hv https://t.co/1kawGbY5nm
