Saturn's moon Enceladus. Image taken by Cassini

One of Saturn's moons might have tipped over

Ingenium – Canada's Museums of Science and Technology

Even nearing the end, the Cassini spacecraft is still producing amazing science. This story focuses on Saturn's moon Enceladus; researchers from Cornell University in New York say they have found evidence that the moon has changed its polar axis of spin. This is based on features they've found on the surface of the moon.

Saturn's moon Titan.

Summer Arrives on Titan

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The Cassini spacecraft took this image of the north pole of Titan, the largest moon of Saturn, in the near-infrared. The dark spots near the top of the image are Titan's massive polar lakes of methane. Also visible are white streaks of cloud. The Saturnian system has moved into summer solstice for the northern hemisphere, shedding more light on Titan's north pole.

Understanding Saturn, its rings, and its moons: The Cassini-Huygens Mission

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The Cassini-Huygens spacecraft is a dual orbiter (Cassini) and lander (Huygens) currently orbiting Saturn. It launched from Cape Canaveral on October 15, 1997, entered orbit around Saturn on the July 1, 2004, and has been studying the Saturnian system ever since. After two mission extensions, and a grand total of almost 13 years orbiting the giant gas planet, Cassini-Huygens’ mission is now coming to a close. The European Space Agency (ESA) built and operated the Huygens lander, which flew with

Three moons of Saturn collected in one image: Atlas, Pan, Daphnis. These moons have large equatorial bulges.

The Walnut-Shaped Moons of Saturn

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The Cassini spacecraft has made some truly remarkable discoveries within the Saturnian system, where it has been orbiting for the last 13 years. One such discovery is of the walnut-shaped moons: Atlas, Daphnis, and Pan. These moons sport a prominent equatorial ridge pattern circumnavigating the moons (Saturn's moon Iapetus also as an equatorial feature, though not as prominent as these). The ridges are due to where the moons are located. They are all located in or very near to the ring system,

What You Need to Know About the Final 11 Orbits of Cassini

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The Cassini spacecraft has only 11 more orbits left of the ringed planet Saturn before its destruction. On September 15th, 2017, Cassini will make a planned plunge into the clouds of Saturn, which will cause it to break up. The science is packed in for Cassini over these orbits: it will study the rings by imaging and sampling, create a more accurate gravitational map of Saturn, and measure the magnetic field of Saturn. Here take a look at the summary of science in the final phase of the Grand

Cassini's first dive, finds "The Big Empty"

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The Cassini spacecraft successfully completed its first dive between the planet Saturn and its rings, something no other craft had done before. Before attempting the dive, scientists weren't sure exactly how much dust/debris would exist in this gap. As a precaution, the orbital scientists oriented Cassini so that its radio antennae pointed in the direction of its trajectory to help protect some of its more sensitive instruments. While performing the dive, mission scientists performed

Cassini Makes its First Dive Between Saturn and its Rings

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

NASA's Cassini-Huygens mission has begun its final mission phase, making its first dive between the planet Saturn and its rings. It is the only craft to ever make that plunge. Check out some of the amazing images it took as it went through, including the north pole hexagonal vortex.

Cassini Dives Closest to Saturn's Atmosphere Ever

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

The NASA/ESA Cassini spacecraft completed its first of 22 dives between the planet Saturn and its ring system; no spacecraft has ever flown that trajectory before. During the pass by the rings, Cassini was out of radio contact. Upon regaining communications, Cassini sent back an image of Saturn, the closest of the planet ever taken. Cassini will continue to dive closer and closer to the atmosphere of Saturn until it ultimately burns up on September 15th, 2017.

The Dark Chasm of Tethys

Ingenium – Canada's Museums of Science and Technology

The NASA/ESA Mission to Saturn, the Cassini-Huygens spacecraft, snapped this shot of the moon Tethys, a 1000 km wide moon of Saturn. Featured in the lower right is Ithaca Chasm. This canyon is about 100 km wide and 2000 km long; it stretches nearly 75% around the moon itself.

The Beginning of the End for Cassini

Jesse Rogerson, PhD

Ingenium – Canada's Museums of Science and Technology

A short description of the upcoming Grand Finale of the Cassini Spacecraft. Over the next 5 months, Cassini will make 22 plunges between Saturn's rings and the planet itself. No craft has ever been that close. During this final phase, Cassini will make close up measurements of the rings for the first time, image the planet's cloud-tops in unprecedented detail, and even answer long-standing questions like: how fast does Saturn actually rotate? It's going to be a very interesting 5 months.
