The Sun not setting over the Earth's limb🌅 You know that in one day astronauts on board the ISS can observe up to 16 sunrises and sunsets. But at times when the station's orbit passes near the terminator (the line separating the illuminated and unilluminated sides of the planet), the Sun may not set at all for its inhabitants. The ISS is not always near the terminator, as this line shifts throughout the year due to the tilt of the Earth's axis of rotation.

A giant catapult is being developed in California to hurl satellites into space without using fuel. Inside the structure, satellites will be spun up to speeds of 8,000 kilometres per hour and then simply thrown into low orbit. It's estimated they'll fly six times faster than the speed of sound. The company has already conducted a bunch of successful tests and has started building a full-fledged catapult

The Sun has set behind Saturn, but Saturn's rings continue to be illuminated. The rings illuminate the back side of Saturn. The result is an interesting photograph.
