It’s going to be a long night. In the Northern Hemisphere, that is. Tonight is the #WinterSolstice, which occurs when either of Earth's poles reaches its maximum tilt away from the Sun. This happens twice yearly, once in each hemisphere. Learn more: https://t.co/ajZ6kJlVXw https://t.co/je6JDLHe8F — PolitiTweet.org

@NASAJPL From measuring marsquakes to detecting meteoroid impacts, @NASAInSight gave us a unique perspective of the Red Planet. While the lander may no longer be operational, we’ll continue learning about Mars with the data it has left us. We thank and congratulate the InSight team. https://t.co/8a4Ln54swy — PolitiTweet.org

@akashactt Yes—these images were taken by @NASAInSight earlier this year. InSight captured thousands of photos of the Red Planet: https://t.co/618nF6PNQ6 — PolitiTweet.org

After more than four years, 1,300 marsquakes, and countless scientific discoveries, our @NASAInSight lander has reached the end of its mission. InSight may be retiring, but its legacy—and its findings from the deep interior of Mars—will live on: https://t.co/8884Slrbxr https://t.co/UKozd4P28g — PolitiTweet.org

Apollo 17, the most recent mission to land on the Moon, splashed down in the Pacific Ocean today (Dec. 19) in 1972. What we learned from Apollo is preparing us for @NASAArtemis missions, which will return humanity to the lunar surface. https://t.co/90TMy1TsjM https://t.co/RPPVBfYywW — PolitiTweet.org

@TomLankford3 The ocean’s waves, tides, and currents cause it to have highs and lows, similar to hills and valleys. Ocean Topography measures these relative to the geoid, where water height is uniform. Measuring topography helps us to better understand large-scale ocean circulation and tides. — PolitiTweet.org
