1 Teacher Edition EMR: Investigation 2 Integrative Science, Technology, Engineering, and Mathematics Electromagnetic Radiation Investigation 2 NASA JUNO Mission Instructional Objectives Students will: discuss the characteristics of Jupiter and describe the components of the JUNO mission; identify criteria and constraints for the challenge; define unit vocabulary; discuss and describe one of the missions from the JUNO mission; describe and give the purpose of an instrument on the JUNO spacecraft; describe and give a spinoff application of an instrument on the JUNO spacecraft. Background This investigation is part of the EMR Unit of the Robotics and Engineering Design Curriculum. The goal of the investigation is to provide the students with an introduction to electromagnetic radiation concepts and give an overview of the NASA JUNO mission. The investigation will provide the students the opportunity to discover the behavior and characteristics of waves and their applications to the overall 8 week unit. What are the goals of the Juno mission? The Giant Planet Story is the Story of the Solar System Juno's principal goal is to understand the origin and evolution of Jupiter. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.

2 Teacher Edition EMR: Investigation 2 With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras. Juno will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system.

6 ELECTROMAGNETIC RADIATION I- 2 OPENING ACTIVITY POCKET SOLAR SYSTEM Every wonder about the size of the Solar System? Start with a strip of paper Sun and Pluto- Draw just the very edge of the sun on one end of the tape and label it. Draw the smallest dot you can on the other end of the tape and label it Pluto. Uranus (1/2)- Fold the tape in half, crease it, unfold and lay flat. Saturn (1/4) and Neptune (3/4)- Fold the tape back in half, then in half again Draw a circle a lirle bigger than a quarter on the 1/4th mark (closer to the Sun) and label it Saturn. Draw another nickel- sized circle on the 3/4th mark (closer to Pluto) and label it Neptune. Jupiter (1/8)- Fold back into quarters, then in half one more Zme - eighths. Draw the largest circle you can at the 1/8 mark (between the Sun and Saturn), and label it Jupiter. 133 Funded by the Georgia Dept. of Ed. through the U.S. Dept. of Ed. Race to the Top grant

7 ELECTROMAGNETIC RADIATION I- 2 OPENING ACTIVITY POCKET SOLAR SYSTEM Asteroid Belt- For the terrestrial (rocky) planets, you only need 1/2 of the first 1/8 th. Fold the Sun end of the solar system in to meet Jupiter at the 1/16th spot. A planet does not go on the new crease, but the asteroid belt does. Earth (Inside 1/32), Mars (Outside 1/32)- Fold the first 1/16th in half by folding the Sun end of the solar system in to the crease at the 1/32nd spot, where the asteroid belt is. Draw a small circle about the size of a Nerds candy for Earth just inside this fold (closer to the Sun) and a slightly smaller circle for Mars just outside the fold (closer to the Asteroid Belt) and label them. Mercury & Venus (Between Earth and Sun)- Between the Sun and Earth are two more planets, Mercury, closer to the Sun and Venus, closer to Earth. As best you can, evenly space these planets out in the space you have lea between the Sun and Earth. Draw a small circle a lirle smaller than Mars for Mercury and about the same size as Earth for Venus. 134 Funded by the Georgia Dept. of Ed. through the U.S. Dept. of Ed. Race to the Top grant

12 Student Sheet - EMR RFP EMR: Investigation Request for Proposals: Solicitation 1S2012 Space In Action Inc Atlanta Ave. Atlanta, GA Full Proposal Deadline (Due by end of class) Fill due date here Important Information and Proposal Requirements A complete set of documentation is necessary at the time of proposal submission. Single proposal from each group. The Juno Bot project team will review all proposals. The following is a list of the required components for all entries: o Letter of Response o Documentation of the testing conducted on test device References to Math and Science concepts utilized o Completed design checklist o Documentation of all test devices o Final working model o Presentation of the group model and findings Project Description Space In Action, an up and coming robot designer is seeking proposals as part of the Juno Bot Project. The project is to design a solar panel arm that will be used to deploy the two solar panels the spacecraft depends on for space flight. As a robot design company, many of our devices require specific parts that require outside production. We are seeking a proposal from companies with solutions that demonstrate appropriate testing procedures and rationale for the design submitted. We are interested in designs that increase the pre- designed robot s effectiveness and reliability of opening both panels as the robot prepares for simulated space flight. In the Juno mission there will be only one opportunity for successful solar panel deployment. You may only present one solution per group but we need documentation that demonstrates multiple iterations of design and complete documentation of the testing of each design including the ideal power for solar panel deployment. All submissions should be sent to our company offices to the attention of Mr. Leo Mars, Director of Engineering Systems, by the date specified above.

13 Student Sheet - EMR RFP EMR: Investigation Juno Bot Mission Objectives As part of the project, the programming division of Space In Action Inc. is seeking help in completing the programming portion of the Juno project. The company has already finished the basics of the program, but is looking for assistance in implementing the finishing touches to insure reliable results during the mission. The Juno bot must complete the following objectives in order for the mission to be considered a success. Robot Launch The robot must initially follow the line using the light sensor to reach the spot for solar panel deployment. Deploy Solar Panels at 1 st chrome marker. (This is a critical portion of the mission, if not completed the mission must be restarted) The robot must react to the chrome marker and deploy the solar panels at this point. Both panels must open. Use gravity assist from Earth flyby With the solar panels deployed, the robot must revert back to following the line around Earth to reach the second chrome marker. Transition to IR tracking at 2 nd chrome marker The robot will transition to using the IR sensor to locate and approach Jupiter. Position Spacecraft for orbit at the chrome line beside Jupiter The robot must be aligned to successfully complete one orbit around Jupiter. Complete one orbit of Jupiter The robot must complete an orbit of Jupiter without crashing into the planet. Reconfigure light sensor and data log cloud bands The light sensor connected to port 3 must be positioned to data log the cloud bands on Jupiter as the robot completes one last orbit. Report relative position of cloud bands After the last orbit the data collected by the light sensor must be used to illustrate the position of the cloud bands on Jupiter.
