Goodbye to Cassini

By Dr. Lisa Will

On Friday, September 15, 2017, NASA’s Cassini spacecraft will end its long mission by plunging into Saturn. Cassini was launched in 1997 and arrived at Saturn in 2004. It was the first spacecraft to go into orbit around Saturn and has sent back spectacular data that has vastly expanded our knowledge of Saturn, its rings and its moons.

Some of Cassini’s accomplishments include:

·         Landing the European Space Agency’s Huygens probe on Titan.

·         Discovering the water ice plumes of Enceladus.

Jupiter’s Great Red Spot Up Close!

By Dr. Lisa Will, resident astronomer at the Fleet Science Center. 

NASA’s Juno mission reached Jupiter on July 4, 2016, after a five-year space voyage. On board Juno is a built-in camera, JunoCam, built by San Diego-based Malin Space Sciences Systems. In August 2016, JunoCam started taking the highest-resolution images ever captured of Jupiter, including the first to feature the planet’s polar regions.

Evidence for a Ninth Planet

You may have heard that there is evidence of a possible new ninth planet in our solar system, but what exactly does that mean? What evidence was found?
