During a busy first year in
orbit around Saturn, the Cassini spacecraft got its first close - up look at the ringed planet's sixth - largest moon,
Enceladus — and wowed scientists in the process.
These findings agree well with the discovery last year by Cassini that
Enceladus undergoes large back - and - forth oscillations, called libration,
during its
orbit.
Because the icy moon is not perfectly spherical — and because it goes slightly faster and slower
during different portions of its
orbit around Saturn — the giant planet subtly rocks
Enceladus back and forth as it rotates.
Cassini took nearly a half - million images
during its mission, which included more than 13 years in
orbit around Saturn, a tour that repeatedly took the probe by the moons Titan and
Enceladus, two places scientists are eager to send another spacecraft in the search for microbial life.
