Video: Rosetta scientist Matt Taylor on the end of mission

NASA’s Cassini spacecraft sped by the moon Titan on Saturday, using the hazy world’s gravity to slingshot the probe on a trailblazing trajectory to explore the region between Saturn’s hydrogen-helium atmosphere and the planet’s famous rings for the first time.

Two weeks into its mission of exploration on Mars, NASA’s Perseverance rover is doing an “exceptional job” and has completed its first test drive, mission managers said Friday.

Europe’s Rosetta comet probe re-established momentary contact with the Philae lander late Thursday, renewing hopes of starting up the craft’s research instruments after two weeks of radio silence dampened the moods of scientists.
