NASA’s Astronomy Picture of the Day

In today's image, we see a timelapse showing the positioning of Earth over the course of a year as imaged by a satellite in Earth orbit. We can see how the seasons change with more and less light in the Northern and Southern hemisphere as the seasons change.

In today's image, we see the Orion spacecraft around the Moon. This was part of the Artemis I mission which was an uncrewed craft returning to the Moon. Artemis II is scheduled for this coming year which will return astronauts to the Moon for the first time since 1972. This will not be a landing, but a try around the Moon in preparation for a future landing.
