New propulsion systems could enable a mission to Sedna

In the outer reaches of our solar system, far beyond the orbit of Pluto, lies Sedna, one of the most mysterious objects ever discovered. This reddish dwarf planet follows such an extreme orbit that it takes more than 11,000 years to complete a single journey around the sun. Now, scientists are proposing a new mission to reach this distant world using a revolutionary propulsion technology.
