Kraken Mare Xplorer

This is a "near-scale" model of a proposed NASA robotic submarine that will be used for exploring the liquid ethane/methane lakes of Saturn's largest moon, Titan. It is a "near-scale" model due to the lack of detailed, measured drawings for this vessel--I only had two drawings for reference. Titan is Saturn's largest moon and it is the second largest moon in our solar system. Titan was discovered in 1655 by Christian Huygens. The NASA Cassini-Huygens orbiter/probe entered Titan orbit in 2004 with the Huygens descent probe landing on Titan in January 2005. Titan has a methane cycle similar to Earth's water cycle. Lakes exist at high northern latitudes. Lakes and larger seas or mare are filled with liquid ethane and methane. An average, estimated (actual depth is unknown) depth of 20 m for these mare would be equivalent to twice the volume of Earth's oil and gas reserves. The proposed submarine was designed by Ralph Lorenz for NASA Institute for Advanced Concepts (NIAC). There are three bodies of liquid ethane that are targeted for exploration: Kraken-1, Kraken-2, and Ligeia Mare. The large dorsal fin on the explorer is an X-Band Phased Array Antenna. Similarly, the discs on either side of the main mast fin are X-Band Omni Antenna. This model was intentionally designed with numerous holes, channels, and ducts for enabling the vessel to completely submerge in a body of water (e.g., pool, bathtub, bucket, etc.). If you are interested in experimenting with the diving/surfacing abilities of this model, you can tape an Alka-Seltzer tablet inside the nose section. Carefully, poke a couple of small holes in the tape, thread the cap onto the Karken Mare Xplorer, and place the model in some water. As the vessel submerges, the water will activate the tablet and cause an explosion of gas to fill the interior of the ship enabling it to surface. This is an experimental feature of this model and it might not perform to your expectations. Good luck and have fun! Tip: Use Testors Cement for Plastic Models No. 3512 for assembly.
