YOUR MISSION
YOUR MISSION
The GALS Space Agency is designing a new robotic orbiter to collect data about Mars as it orbits the planet. The new orbiter will replace the previous Mars orbiter that was damaged by meteoroids. Designing and building orbiters take a lot of time and the materials are expensive, so the engineers at the GALS Space Agency want to make sure the new orbiter can withstand the collision force of the meteoroids.

Designing and building orbiters take a lot of time and the materials are expensive, so the engineers at the GALS Space Agency want to make sure the new orbiter can withstand the collision force of the meteoroids.
The Space Agency needs to design a new, lightweight shield for a Mars orbiter to protect it from being punctured by meteoroids in space. The shied materials for the prototype orbiter cannot exceed 40 grams in mass and 100 millimeters in thickness; otherwise, it will be too heavy to launch into space.

Write a procedure for testing the meteoroid depth. Make sure this is a numbered vertical list. You might consider:
Write a procedure for testing the meteoroid depth. Make sure this is a numbered vertical list. You might consider:
Rest the test tube vertically on the surface of the prototype (which is on top of the foam board). Drop the meteoroid simulator (screwdriver) down the test tube. Carefully remove the tube and screwdriver. Use a toothpick and ruler to measure the depth of the hole created in the foam board.

STEP 8: Refine or Replicate
STEP 8: Refine or Replicate
Did your meteoroid shield successfully protect your orbiter from damage? If so, move on. If not, go back and create another prototype and repeat steps 5-7 for the next prototype.

Once you are satisfied with your design, write the following for STEP 8 in paragraph form:
- Restate problem ("The problem we were trying to solve was ... ")
- Make a claim ("Our design is ready to be replicated." OR "Our design needs to be refined further.")
- Support claim with evidence from test (make sure you include actual DATA (NUMBERS) from your data table)
- Concluding sentence ("In conclusion, we found that ... ")
