When Christina Koch returns to Earth, she will have spent 355 days in space, the longest space flight ever made by a woman. On August 26, she posted images on Twitter for her 164 days in orbit.
Earlier this year, the astronaut posted an image of the passage from Earth to the night.
A couple times a year, the @Space_Station orbit happens to be in the sky. We are continually in sunlight, never passing into Earth's shadow from the Sun, and the Earth is here in dawn or dusk. Beautiful time to cloud watch. #nofilter pic.twitter.com/BYDLv8RFVr

"A few times a year, the space station's orbit aligns with the day / night shadow line on the Earth. We are continually in the light of the Sun, we never go into the shadow of the Earth, and the Earth below us is always at dawn or dusk, "wrote the astronaut.
According to NASA, the ISS is flying at an altitude of about 355 km and making a complete turn of the planet every 92 minutes. It travels at an astonishing speed of 27,359 km / h, allowing astronauts to see 15 or 16 sunrises and sunsets each day.
