2023年11月18日 Planet Earth from Orion Image Credit: NASA, Artemis I Explanation: One year ago a Space Launch System rocket left planet Earth on November 16, 2022 at 1:47am EST carrying the Orion spacecraft on the Artemis I mission, the first integrated test of NASA’s deep space exploration systems. Over an hour after liftoff from Kennedy Space Center’s historic Launch Complex 39B, one of Orion’s external video cameras captured this view of its new perspective from space. In the foreground are Orion’s Orbital Maneuvering System engine and auxillary engines, at the bottom of the European Service Module. Beyond one of the module’s 7-meter long extended solar array wings lies the spacecraft’s beautiful home world. Making close flybys of the lunar surface and reaching a retrograde orbit…

2022年9月9日 Interstellar Voyager Poster Illustration Credit: NASA, JPL-Caltech, Voyager Explanation: Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence of the solar wind and the Sun’s magnetic field. On the 45th year of their journey toward the stars Voyager 1 and 2 reached nearly 22 light-hours and 18 light-hours from the Sun respectively and remain the only spacecraft currently exploring interstellar space. Each spacecraft carries a 12-inch gold-plated copper disk with recordings of sounds, pictures and messages. The Golden Records are intended to communicate a story of life and…

2019 August 25 Leaving Earth Video Credit: NASA/JHU Applied Physics Lab/Carnegie Inst. Washington Explanation: What it would look like to leave planet Earth? Such an event was recorded visually in great detail by the MESSENGER spacecraft as it swung back past the Earth, eight years ago, on its way in toward the planet Mercury. Earth can be seen rotating in this time-lapse video, as it recedes into the distance. The sunlit half of Earth is so bright that background stars are not visible. The robotic MESSENGER spacecraft is now in orbit around Mercury and has recently concluded the first complete map of the surface. On occasion, MESSENGER has continued to peer back at its home world. MESSENGER is one of the few things created on…
