Farewell Cassini

One of Saturn's moons above its rings against star-lit space.
If you like science and dream of exploring the stars or going into space one day, then you are probably aware of the Cassini mission. The probe recently took its last photo just as it entered the Venus atmosphere, but before the camera faded to black it took many beautiful photos.

If you are not science buff, "Cassini-Huygens is one of the most ambitious missions NASA ever launched into space. Loaded with an array of powerful instruments and cameras, the spacecraft is capable of taking accurate measurements and detailed images in a variety of atmospheric conditions and light spectra."

Cassini reached Saturn in July 2004 and has been dubbed one of the most successful of NASA's many missions. It's "scripted death dive" occurred on September 15, 2017.

What are some of the missions biggest discoveries?

One of its moons, Enceladus, shows evidence of water-based ice and a subsurface ocean leading to speculation about the presence of life.

Another moon, Titan, has earth-like rain, rivers, lakes and seas - although it is liquid methane, not water. I wonder what kind of being would live on a methane planet?

The rings are a laboratory for how planets are formed, colliding and separating. Scientists even think they witnessed the birth of a new moon.

But it's the pictures - those close up and personal pictures of a planet in our solar system that attract a lot of attention. They are just beautiful.

Do you want to visit another planet someday? Have you visited the planetarium on campus? Do you think people will be living on other planets in your lifetime?

  1. I want to visit Neptune because it rains diamonds. No, I haven't visited the planetarium. No people in my lifetime won't be able to visit another planet because they don't take care of ours.
