NASA's flying telescope to study Saturn moon, comet in 2018
NASA's SOFIA, a Boeing jetliner modified to carry a 100-inch-diameter telescope, is preparing for its 2018 observing campaign, which will include observations of celestial magnetic fields, star-forming regions, and Saturn's largest moon Titan among others. Further, SOFIA will study comet 46P as it passes close to Earth, to understand Solar System's origin. It would also probe Mars' methane levels.
