"As anticipated, seasonal decline in sunshine at the robot's arctic landing site is not providing enough sunlight for the solar arrays to collect the power necessary to charge batteries that operate the lander's instruments, " NASA said in an official statement. The last signal Phoenix sent to Earth was received on November 2; however, NASA engineers will continue to monitor the situation for three weeks in the unlikely event the probe sends another signal. The total length of the mission was just over five months, which was two full months longer than originally scheduled. NASA extended the mission after confirming the presence of water on Mars. Now, NASA scientists will begin to fully analyze the data collected during the mission. Initial data confirms the presence of water found in soil, small concentrations of salt, and that the soil was somewhat alkaline (not acidic as in other places on Mars). The main objective of the Phoenix mission on Mars, also referred to as the Red Planet, was to determine whether life, likely in the form of microbes, has ever been sustained or could be sustained on the planet. Water is a necessary element in order to sustain life, which is why the discovery of water on Mars is so noteworthy. Phoenix, which was the first probe to successfully land in a polar region on Mars, took 25, 000 pictures with the first atomic force microscope ever used outside the boundaries of Earth. Currently, there are two other probes on Mars the Spirit and Opportunity. Mars is located 422 million miles from Earth. It revolves around the sun once every 687 Earth days. Q1. What made NASA lose contact with the Phoenix probe? Q2. Why was the Phoenix mission extended beyond the original three month period? Q3. Why is water such a significant discovery on Mars?

• copies of the article above, one for each student
• chart paper or other form of note demonstration such as a white board
• PowerPoint slideshow on solar orbits

• revolution: the length of time it takes an object to revolve around the sun
• rotation: the length of time it takes an object to rotate around its axis
• perihelion: when a body is closest to the sun in its revolution
• aphelion: when a body is farthest away from the sun in its revolution
• solar power: electricity generated by the capturing of the sun's energy

Day 1 Introduction 1.   Teacher will begin the class with an introduction to Mars and why we are studying it as a planet: because it closely resembles Earth in size and rotational speed, and also because we now have evidence that water once existed on this neighboring planet. 2.   Have the students respond to the following prompt in a journal or notebook to get their thinking started: If we could no longer support life on Earth, what qualities would we have to look for in a new planet? What would we need in order to make life as close to what we have on Earth now? Planetary Rotation and Revolution 3.   Using the PowerPoint slideshow included in this lesson plan, engage the students in a discussion of the concepts of rotation and revolution and the differences between the two. 4.   Discuss how the Earth’ s revolution is the cause of the Earth’ s 365-day year and how the tilt of the Earth’ s axis causes us to experience seasons as we revolve around the sun. 3.   Discuss how the rotation of the Earth around its axis, which takes a little under 24 hours, is responsible for the length of the Earth’ s day. 4.   Compare the length of the Earth’ s rotation and the length of the Earth’ s revolution to those of Mars, based on the chart on planetary motion in the PowerPoint show—how does the Martian day and year compare to that of Earth? Have the students draw a diagram representing the differences between the planets. 5.   Scientists often look to Mars as a place where humans could potentially live in the event that Earth is no longer habitable—how would the differences in the speed of rotation and revolution affect life on Mars? Day 2 Introduction 1.   Teacher should have on the board the steps to the design method so that during the lesson students can reference the process while they work.   Write the following on the board: The Design Process

• Identify the problem or opportunity
• Investigate the problem or opportunity: Gather and analyze information through interviewing, observing, documenting, modeling, weighing choices, identifying your client
• Frame/Reframe the problem: Make sure that you have identified the right problem to solve
• Generate possible solutions
• Edit/Develop ideas: talk with your group about what ideas have the most potential
• Evaluate your ideas Create your solution: Create diagrams, models, and presentations; organize your resources and notes
• Re-Evaluate your solution: Take feedback and analyze how you could make your solution even better

2.   Teacher should pass out a copy of the article to each student and have them take out their journals or notebooks to take notes on what they find interesting or what they have questions about while reading The Mars Rover- problems and possibilities 3.   Using your favorite technique, have the students read the article on NASA’ s Mars Rover program and the recent challenges it has faced due to the oncoming Martian winter (I find it works best when students are reading aloud). 4.   Have the students answer the three discussion questions at the end of the article in their notebooks independently and then discuss the results as a class when they are done. 5.   Using the Design Method on the board, have students, in groups of two, work through the steps of the design process using the information in the article. The goal here is to use the information presented in class the day before along with the article to identify the problems with the Rover as it is—possible problems the students could identify are that the scientists didn’ t account for the lack of sunlight  and should have included a backup power source on the rover, the scientists should have programmed the Rover to change locations during the winter in order to get more sunlight, scientists should have launched the Rover sooner in the Martian year, etc. 6.   Have the student pairs or groups of 3 come up with a solution to the Mars Rover problem, whether it’ s a new design for the Rover itself or a change in the execution of the program. 7.   At the end of the class period, have groups share some of their ideas of changes to the NASA program and how it might help solve the Rover problem.

• Have students write a response to the article questions in their notebooks or journals (these entries should be checked for comprehension and understanding of the subject).
• Have students take notes on their design ideas in their notebooks as well
