Throughout the recent stunning space picture, eight billion individuals are all set to vanish. As seen by an external camera aboard the departing Orion spacecraft on Nov 21, the sixth day during the Artemis 1 mission, astronauts' home world is disappearing behind the Moon's brilliant edge, per NASA. The Orion was on its way to a powered flyby of the moon, which would bring it inside 130 km of the surface.
The speed obtained during the flyby will be utilized to achieve a far retrograde orbital around the Moon. That orbit is deemed far since it is 92,000 kilometers further than the Moon, yet retrograde since the spacecraft will revolve in the reverse direction as the Moon orbits Earth. Thanksgiving day, Friday, Nov 25, Orion just began its far retrograde orbit.
Spinning from around the Moon, Orion may reach its maximum distance from Earth (just over 400,000 km) on Monday, November 28, breaking the record established by Apollo 13 for the farthest distant spacecraft built for human exploration of space.
Capturing The 'Earthset' and 'Earthrise'
A disturbing new shot taken by the Orion spacecraft, which was recently launched into orbit in support of NASA's Artemis I mission, shows a small, faraway Earth beginning to drop behind the moon. The photograph, named "Earthset," is a reverse of the famed "Earthrise" shot acquired by NASA's Apollo 8 expedition more than 50 years ago. After over a month of unsuccessful launches, Artemis I's "giant moon rocket" was ultimately launched into orbit in the pre-dawn hours of Nov. 16.
On the other hand, decades ago, on Christmas Eve, December 24, 1968, Apollo 8, the first space mission to the moon, reached lunar orbit. The astronauts-Commander Frank Borman, Command Module Pilot Jim Lovell, as well as Lunar Module Pilot William Anders, held a live transmission from lunar orbit that evening, showing images of the Earth and moon as seen from their spacecraft. As per Lovell, the enormous loneliness is awe-inspiring, and it makes you appreciate what you have back on Earth, as reported by NASA.
Earth's Apparent Setting Differences
According to Cornell University astronomer Karen Masters, one will never witness the Earth rise or set if they are gazing at the Moon. The reason for this is that one side of the lunar surface is constantly facing the Earth while the other is always facing away. So, in practically any place on the Moon, one either sees or doesn't see the Earth.
She said that virtually anywhere because the Moon 'jiggles' from left to right a little. Over time, a little more than half of the ground is thus observable from the Earth, and at spots near the edge, one may be able to observe the Earth move up and down a little.
Without much more thought, Masters believes that she couldn't answer whether the Earth would entirely rise and descend or whether you might be able to view/not see a portion of it at all times.
What happens when humans read about Earthrise over the Moon is that the image was obtained from a spacecraft circling the Moon. Because it is orbiting the Moon, it can observe the Earth rising as it travels. The various well-known images of this occurrence are from Apollo 8 and the one from Lunar Orbiter 1. (1966).
