Our Mission

Lander

Lander Design

The rover designed for Tiger's Ebb will be strictly terrestrial. It's purpose is to collect 10 or more grams of water-ice from the thin crust of Enceladus. The rover will be equipped with a long, pole-like arm with a drill bit connected to the end. The arm will be collapsible and extend as it penetrates deeper into the surface of Enceladus. Our goal is to drill between 10-20 meters beneath the surface, in order to extract a wide variety of samples. The lander will be autonomous and stationary, our goal is to have it land inside one of the canyons in the southern hemisphere and collect data from that location.

Telescopic arm

The arm will be broken into separate joint-like pieces that will perpetually extend out from one another while the drill bit travels deeper into the crust. The mechanism would be powered by a hydraulic system connected to autonomous depth and pressure sensors to ensure the drilling operates smoothly.

Lander Mechanisms

The lander will be fitted with ATCS or Active Thermal Control System. PTCS or Passive Thermal Control System. EMI, which is electromagnetic interference. DFMR or Dual Frequency MEECN Receiver. EPC stands for Electronic Power Control. Vernier, which is a mathematical tool used in guidance. MRAC Model-Reference Adaptive Control. CGT or Computer Graphics Technology. It also will have a drill bit and shaft. Collection chamber/analyzing chamber. There are also mechanisms to help us land such as a deployable parachute and protective airbags.

Lander Design

The Enceladus lander will be 7 1/2 meters tall, and 5 meters in width and length.

Orbiter

The orbiter component of Tigers Ebb will be strictly orbital. It's main objectives are to relay information to earth from the rover, and to collect data on Enceladus' atmosphere, temperature and topography. It will be outfitted with: CIRS, Composite Infrared Spectrometer, NIMS or Near-Infrared Mapping Spectrometer. X-ray Spectroscopy, which is the absorption and emission in the electromagnetic X-ray range to determine the composition and conditions of high-temperature plasmas of galaxies. VIIRS, or Visible Infrared Imaging Radiometer Suite. SWOT, or Surface Water and Ocean Topography.

ISE which is indirect ion-specific electrode.

Emission Spectroscopy, a family of chemical analysis techniques involving electromagnetic radiation.

Orbiter design

The Enceladus orbiter will be 5 meters tall, 10 meters in length and 5 meters in width.

Systems Requirements

The systems requirements for Tiger's Ebb are the outline for what our design will need to achieve in order to conduct a successful mission. The team designated a number of goals to consider, like being able to withstand solar radiation, and ensuring communications can stay online throughout the mission. This was the teams first step in our project and we based the rest of our research and design around these requirements.

Hypothesis

Through the mission, Tigers Ebb, the team believes we will discover a source of anomalous heating in the southern hemisphere of Enceladus. We will be able to extrapolate our topographical, thermal and chemical data to discover where and why this heating is occurring. As a secondary effect of this mission, Enceladus will be mapped much more clearly, and high quality images of the moons surface will be procured. As a bonus to this mission, the team hopes to find possible signs of life within the moons crust.

SUBSYSTEMS

Tigers Ebb has been a collaborative effort, with 6 individuals working to solidify this hypothetical mission. In order to efficiently procure research and work towards our final presentation, each member was assigned a different set of subsystems. Each subsystem is a vital part of the mission and requires a strenuous amount of research to be assessed accurately. Thus our team has divided our research into 11 of these subsystems, listed in the research tab.

Trade Studies

Each team member performed a series of trade studies to determine what materials and designs would be most effective in achieving the missions goal. The trade studies entail the designation of a number of possible materials or mechanisms that could be used in our mission. The team member weighed the pros and cons of each of these possibilities through the use of their trade studies diagrams.
