Europa, the sixth largest moon in the solar system, has been discovered to be an ice queen. The quest for more knowledge about Europa has led scientists to convene in Paris to tackle different proposals for new Europa missions. Scientists have already been captivated by one of Jupiter's moons known as "Jupiter II" since its discovery in 1610 by Galileo. 

According to BBC News, scientists have quite a number of ideas that could count as add-ons to the U.S. missions that are most likely to happen in 2022. The ideas range from remote-sensing instruments to penetrators. The aim is to punch a hole on Europa's ice-filled surface. However, the idea has to win the approval and support of the European Space Agency.

The organization based in Paris is on the verge of issuing an announcement to fill a medium-cost launch opportunity. The invitation will cover the full spectrum of space exploration and not merely planetary science. The exploration will range from as normal as remote-sensing instruments orbiting the moon and collecting data from above to the bizarre firing of burrow sensors into Europa's icy surface to study the moon closely, inverse.com reported.
