media type="custom" key="23739818" When traveling in space, the space vehicle protects astronauts from space debris, which usually can be seen, and space radiation, which cannot be seen. One of the most difficult things to block is space radiation, and it is also the most deadly. Space radiation affects human cells and tissues. For long space missions, materials used to build the spacecraft must give the space explorer more protection from space radiation than what is currently provided. NASA and Lockheed Martin are developing the Orion Multi-Purpose Crew Vehicle. Orion will serve as the exploration vehicle that will carry the crew to space and protect them during extended space travel.

MRS. DE TORRE MRS. ZIEGELBAUER 3RD GRADE SCIENCE TEACHERS
 * OUR OBJECTIVE:**
 * 1) Material Designers: Students will analyze different materials to simulate space radiation shielding on a spacecraft and select the best material to build a spacecraft.
 * 2) Structural Engineers: Students will calculate the amount of the various materials needed to create the model and put together "supply boxes."
 * 3) Construction Crew: Students will use the information from the structural engineers and material designers to construct a model spacecraft.
