Because Titan is tidally locked, the same side of the moon faces Saturn all the time, just like our own moon and Earth.

Nasa’s mission teams use extreme environments to trial equipment and procedures for future lunar and planetary exploration.

By chance, NASA Europa Clipper captured interstellar comet 3I/ATLAS in ultraviolet light as it sped past Earth, revealing hidden gases and offering a rare preview before its Jupiter encounter ahead.

An instrument aboard NASA’s Europa Clipper spacecraft captured rare ultraviolet observations of an interstellar comet while Earth-based telescopes were blinded by the Sun. The spacecraft’s unique ...
