Sci-5 | The Hindu Science Quiz: On Epimetheus
This picture made by the Cassini spacecraft and supplied by NASA on March 12, 2006, reveals two of Saturn’s moons, the small Epimetheus and smog-enshrouded Titan, with Saturn’s A and F rings stretching throughout the body. Launched in 1997, Cassini reached Saturn in 2004 and has been exploring it from orbit ever since. Cassini’s gas tank is sort of empty, so NASA has opted for a dangerous, however science-rich grand finale.

Which spacecraft confirmed the existence of each Janus and Epimetheus in 1980?
- Voyager II
- Cassini
- Voyager I
- Hubble House Telescope
