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 Ering
Cassini
-Found water geysers in the south
pole
-Investigated the composition of
water (found organic chemicals.)
II. Preparing
What we want to investigate?
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 find?
3. Amino Acid
2. DNA
1. RNA
4. H2S
5. CH4 , NH3
Instruments
-Camera
-Sonar
-Laser spectrometer
-GC-MS
-Seismography
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
Mass
Spectrometry
Inner Structure of GC/MS
Using GC/MS
- Observe unknown samples’
Periodical changes of composition
- identify unknown samples that we
collected.
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
