Q&A with Scott Bolton, principal investigator on NASA’s Juno mission

NASA has released an image of Saturn’s moons Enceladus and Tethys caught in a rare alignment by the Cassini spacecraft, which is heading for its final close encounter with the icy moon Enceladus Saturday.

A new generation of spacecraft with unprecedented clarity and speed to observe the weather, improve forecasting and enhance tracking of severe storms across the United States begins with the launch of an Atlas 5 rocket on Saturday.

A technical issue with the United Launch Alliance Atlas 5 rocket that will send NASA’s $2.4 billion Perseverance rover toward Mars has pushed the mission’s launch date back to no earlier than July 30, nearly two weeks into a month-long window for the rover to head to the Red Planet, or else face a two-year delay.
