  1. Europa Clipper is a mission to chatacterize the "habitability" of Europa. That is its goal. The team has been very very careful to not claim that it is looking for life. It is effectively being pitched as an early precursor #OceanWorld #astrobiology mission.

    But...if life were there and evidence was detected by the spacecraft, what instruments might give the hint of a biosignature?

    That might be the mass spectrometer MASPEX.

    What could it detect?

  2. On January 14, 2005, the Huygens probe successfully landed on the surface of Saturn's moon #Titan

    Here is a link to a video clip, as well as links to where you can download this video.

    This was one of the greatest of humankind's achievements....the first time we ever landed on an #OceanWorld.

    But what did we learn? What do these images tell us?

    Thread time!

  3. More differences of #OceanWorld ice.

    Temperature. At top of many icy moons, the ice is waaay colder than Earth. 100 K on many worlds. The coldest on Earth is maybe 200 K. Cold ice is different. Harder, abd high thermal conductivity makes it harder to melt at a spot on surface (heat energy just conducted away.)

    Formation. Ice sheets and glaciers are meteoric ice. Comes from snowfall. On Ocean Worlds (except some areas Enceladus is freeze down ice.
