What important discoveries did Cassini make?

The Cassini spacecraft orbited Saturn from June 30, 2004, until Sept. 15, 2017, when the probe ended its life with a plunge into the ringed planet’s atmosphere. The mission is known for discoveries such as finding jets of water erupting from Enceladus, and tracking down a few new moons for Saturn.

What is the Cassini spacecraft designed to study?

Cassini Orbiter Instruments Cassini’s 12 science instruments were designed to carry out sophisticated scientific studies of Saturn, from collecting data in multiple regions of the electromagnetic spectrum, to studying dust particles, to characterizing Saturn’s plasma environment and magnetosphere.

What did the Cassini spacecraft learn about Saturn and its features?

Titan, Saturn’s largest moon, has an internal, liquid water-ammonia ocean. Cassini’s imaging radar allowed us to see past Titan’s thick, smog-filled atmosphere and revealed vast methane lakes and wind-sculpted hydrocarbon sand dunes.

How was Cassini controlled?

The Cassini space probe was deliberately disposed of via a controlled fall into Saturn’s atmosphere on September 15, 2017, ending its nearly two-decade-long mission. This method was chosen to prevent biological contamination of any of the moons of Saturn now thought to offer potentially habitable environments.

Why did NASA destroy Cassini?

The mission ended on September 15, 2017, when Cassini’s trajectory took it into Saturn’s upper atmosphere and it burned up in order to prevent any risk of contaminating Saturn’s moons, which might have offered habitable environments to stowaway terrestrial microbes on the spacecraft.

Why did they crash Cassini?

Having expended almost every bit of the rocket propellant it carried to Saturn, operators deliberately plunged Cassini into the planet to ensure Saturn’s moons remain pristine for future exploration—in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.

Was Cassini successful?

NASA’s Cassini mission crashed and burned — and was a huge success.

How long did Huygens last on Titan?

153 minutes

Which planets Cannot be seen with naked eyes?

Which planets are visible to the naked eye from Earth? Mercury, Venus, Mars, Jupiter and Saturn are visible for much of the year. Neptune and Uranus are not visible – and of course the eighth planet in our solar system is Earth itself.

Why is Venus called Earth’s twin?

Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. The size of Venus is only a little smaller than our home planet, with a mass that’s about 80% of Earth’s.

Who is Earth’s evil twin?


Do we have an evil twin?

In astronomy, Venus is often called Earth’s “evil twin”, in reference to the similarity, yet opposition, of the two bodies. It is also a commonly asked question twins get and there are various view points on this.
