Assume you are at the center of the South Pole of Mars. In this area directly around the South Pole, the Martian surface can be assumed to initially be uniform. Since you are at the ice caps of Mars, the physical constants of the ground are similar to ice.
See attached file for equation.
Suppose the atmospheric gas directly above the surface drops to -260 °F. This will affect the ground below. How deep below the surface would you find the temperature of Mars to be -254 °F after a) 1 hour b) 3 hours.

Mars Global Surveyor spacecraft orbits Mars collecting data. It has collected more Martian images than all the past Mars missions combined. This graph contains information about the surface temperature of Mars collected by the Mars Global Surveyor using a thermal emission spectrometer.
This image from NASA/JPL shows surface temperatures for the south pole of Mars.

This problem includes actual temperature data collected from the Mars Global Surveyor. This was collected from the Thermal Emission Spectrometer. The problem involves using the properties of Mars, the collected temperature data, and dimensionless parameter formula to determine the time involved with a transient solution and corresponding temperature below the Martian surface. Fun way to practice key heat transfer problem fundamentals!
Physical and chemical control of growth and viability (CASE)
In the module 3 case assignment you will explore bacterial growth and methods used to measure the growth of microbes. After you have read the information in the background readings and home page you should prepare a paper addressing the topics below:
1. Discuss the four phases of the bacterial growth curve.
2. Explain two methods used to measure microbial growth.
3. Discuss two methods used to control microbial growth.
The book Antibacterial Agents: Chemistry, Mode of Action, Mechanisms of Resistance and Clinical Applications on your ebrary bookshelf will be an important place to begin your research on this topic.
Case Assignment Expectations
Length: Case Assignment Module assignments should be at least 2-4 pages (400-800 words) in length.
References: At least two references should be included from academic sources (e.g. peer-reviewed journal articles). Required readings are included. Quoted material should not exceed 10% of the total paper (since the focus of these assignments is critical thinking). Use your own words and build on the ideas of others. When material is copied verbatim from external sources, it MUST be enclosed in quotes. The references should be cited within the text and also listed at the end of the assignment in the References section (preferably in APA format).
Organization: Subheadings should be used to organize your paper according to question
The following items will be assessed in particular:
Relevance (e.g. all content is connected to the question)
Precision (e.g. specific question is addressed. Statements, facts, and statistics are specific and accurate).
Depth of discussion (e.g. present and integrate points that lead to deeper issues)
Breadth (e.g. multiple perspectives and references, multiple issues/factors considered)
Evidence (e.g. points are well-supported with facts, statistics and references)
Logic (e.g. presented discussion makes sense, conclusions are logically supported by premises, statements, or factual information)
Clarity (e.g. writing is concise, understandable, and contains sufficient detail or examples)
Objectivity (e.g. avoid use of first person and subjective bias)
