If you've seen a recent photo of Saturn (such as the one above), it's likely from the Cassini spacecraft. The 10th anniversary of the Cassini spacecraft reaching the Saturn system (the planet and its moons) occurred on June 30th.  The spacecraft is named after Giovanni Cassini, an accomplished scientist who, among other things, noted a gap between the rings of Saturn now known as the Cassini Division. This is the dark area within the rings of the above photo.

Ten years later, and our understanding of our system has been greatly enhanced by the discoveries of the Cassini spacecraft. Check out an infographic followed by the top 10 accomplishments of the program:

Below are the top accomplishments from the Cassini spacecraft in the past 10 years:

-- The Huygens probe makes first landing on a moon in the outer solar system (Titan)

-- Discovery of active, icy plumes on the Saturnian moon Enceladus

-- Saturn’s rings revealed as active and dynamic -- a laboratory for how planets form

-- Titan revealed as an Earth-like world with rain, rivers, lakes and seas

-- Studies of Saturn's great northern storm of 2010-2011

-- Studies reveal radio-wave patterns are not tied to Saturn’s interior rotation, as previously thought

-- Vertical structures in the rings imaged for the first time

-- Study of prebiotic chemistry on Titan

-- Mystery of the dual, bright-dark surface of the moon Iapetus solved

-- First complete view of the north polar hexagon and discovery of giant hurricanes at both of Saturn's poles

#ScienceLooksGood: Bringing Light to the Dark Universe

 

The Kennedy Space Center (KSC) is celebrating its 50th anniversary this week. It previously served as the staging area for the Space Shuttle program.  This has helped us to bring light to previously unknown things about the universe, and has enabled us to launch everything from satellites to parts of the International Space Station (ISS) to the Hubble Telescope.

The European Space Agency (ESA) is looking to bring light to the darkness by clearing a mission to  launch the Euclid telescope in 2020. All of the things that we can see with our weak human eyes - planets, stars, people, etc - make up about 4% of the actual universe. The rest of the universe is known as "dark matter" - a substance that only a power telescope can begin to detect.


 

 

The telescope will capture images for six years - check out the main mission site here.
