I. Information about Enceladus

About Enceladus Cycle of revolution1.37 days Diameter500km SurfaceCovered with ice Temperature -210 Acceleration of gravity0.114m/s 2 Composition of AtmostphereH 2 O(91%), N(4%), CO 2 (3.2%), CH 4 (1.7%) Mass1.082 X 10 20

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. H 2 S 5. CH 4, NH 3

-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 Mass Spectrometry

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

Timeline Feb, 2027 Lander completes dissolving ice. Separate submarine(probe) and start probing. Jan, 2020 Lift off.Aug, 2021 Swing by at Venus.Oct, 2021 Swing by at Earth. Apr, 2023 Swing by at Jupiter. Sep, 2026 Go into the Saturn's orbit Nov, 2026 Go into the Enceladus' orbit, start mapping. Dec, 2026 Dropping lander and three seismographs Lander starts dissolving ice

seismography lander spacecraft Find appropriate area by using Thermal/visible camera

The Front Of Submarine Thermal/visible Camera

1. Find small particles easily 2. Increase the probability that we find biomarkers 3. Measure changes of composition The Side Of Submarine Sonar Laser Spectrometer Laser Spectrometer Antenna GC/MS Computer RTG
