About Enceladus

Cycle of revolution 1.37 days

Diameter 500km

Surface Covered with ice

Temperature -210℃

Acceleration of gravity 0.114m/s2

Composition of Atmostphere H2O(91%), N(4%), CO2(3.2%), CH4 (1.7%)

Mass 1.082 X 1020

Mission Objective

Mission Statement: 1. Searching for life in Enceladus 2. Investigating the environment of Enceladus

Science Goals 1. Clarifying whether Enceladus has lives or not. 2. Investigating the structure of Enceladus.

Why is Enceladus important?

- Organic chemicals (Cassini found it)

- Magnetic field (from Saturn, protect solar wind)

- Energy

- Water

Previous research

Voyagers- Measured its diameter about

500km long- Enceladus was located in the

densest part of Saturn's diffuse E-ring

Cassini- Found water geysers in the south

pole- Investigated the composition of

water (found organic chemicals.)

II. Preparing

1. Conditions of water (composition, temperature, etc)

2. Isotope of carbon, hydrogen, oxygen, nitrogen, sulfur

3. Periodical changes of composition

4. Physical conditions inside of the Ocean

5. Structure of Enceladus

6. Configuration of the ocean floor

What we want to investigate?

What we want to find?

1. RNA

2. DNA

3. Amino Acid

4. H2S

5. CH4 , NH3

-Camera

-Sonar

-Laser spectrometer

-GC-MS

-Seismography

Instruments

Instruments - Camera

-At least, two kinds of lens one for visible, other for infrared

-Take pictures

-Make videos

-Investigate temperature

-Find out the most thin layer

Instruments - Sonar

Principle of Sonar

- The principle : Reflection of supersonic waves.

Mapping

- Map the geographical features.

Instruments - Laser Spectrometer

- Composition of the gas

- Whether there are some particles or not.

?

Instruments – GC/MS(Gas Chromatography/Mass

Spectrometry)

Gas Chromatograph

MassSpectrometry

Inner Structure of GC/MS

- identify unknown samples that we collected.

Using GC/MS

- Observe unknown samples’ Periodical changes of composition

Instruments - Seismography

- Investigating the inner structure of Enceladus

- Using 3 Seismography forming an equilateral triangle shape.

III. Launching and investigation

Where is the most interesting place?

-The south pole

And why??

-geysers-Biomarkers
