Get ready, we’re going to Europa! NASA’s plan to send a spacecraft to explore Jupiter’s moon just passed a major hurdle. The mission, planned for the 2020s, now has NASA’s official stamp of approval and was given the green light to move from concept phase to development phase.

Formerly known as Europa Clipper, the mission will temporarily be referred to as the Europa Multi Flyby Mission until it is given an official name. The current mission plan would include 45 separate flybys around the moon while orbiting Jupiter every two weeks. “We are taking an exciting step from concept to mission in our quest to find signs of life beyond Earth,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate, said in a press release.

Since Galileo first turned a spyglass up to the skies and discovered the Jovian moon, Europa has been a world of intrigue. In the 1970s, we received our first look at Europa through the eyes of Pioneer 10 and 11, followed closely by the twin Voyager satellites in the 1980s. Their images provided the first detailed view of the Solar System’s smoothest body. These photos also delivered evidence that the moon might be harboring a subsurface ocean. In the mid 1990s, the Galileo spacecraft gave us the best view to-date of Europa’s surface.

"Observations of Europa have provided us with tantalizing clues over the last two decades, and the time has come to seek answers to one of humanity's most profound questions," Grunsfeld said. “Mainly, is there life beyond Earth?”
