  1. Space Systems Engineering and Design Our journeys to the stars will be made on spaceships created by determined, hardworking scientists and engineers applying the principles of science, not aboard flying saucers piloted by little gray aliens from some other dimension. — Robert A. Baker in “The Aliens Among Us: Hypnotic Regression Revisited”, The Skeptical Inquirer, Vol. XII, No. 2, 1988 C. Hall, Randolph 224D cdhall@vt.edu

  2. The Spacein Aerospaceand Ocean Engineering Courses, Labs, Research Space Jobs Astronautics references Course overview Chris Hall, Randolph 224D cdhall@vt.edu (540) 231-2314 www.aoe.vt.edu/~chall/courses/aoe2104

  3. Space-Relevance of AE Curriculum • Mathematics - space systems must be modeled and analyzed mathematically • Computational methods - space systems models must be analyzed numerically • Mechanics - space systems have mechanical components undergoing static and dynamic loads • Aerodynamics - space systems must be launched through the atmosphere, and sometimes reenter the atmosphere C. Hall, Randolph 224D cdhall@vt.edu

  4. Required Courses AOE 4134 Astromechanics (Fall of Jr or Sr Year) • Required in junior year in order to take Space Design • Orbital dynamics of satellites and interplanetary probes AOE 4065/6 Design (Fall/Spring, Sr Year) • Required Course with choice between Aircraft and Spacecraft options • Recent spacecraft projects: • CubeSat (TransOrbital) • Sounding Rocket Payload (NASA Wallops Island) • MicroMAPS (NASA Langley) • Tether Launch System for Mars Missions (AIAA) • PowerSail (USAF) C. Hall, Randolph 224D cdhall@vt.edu

  5. Elective Courses AOE 4140 Attitude Dynamics (Spring, Jr or Sr Year) • Required in junior year in order to take Space Design (in lieu or AOE 3134 Stability & Control) • Pointing dynamics and control of spacecraft AOE 4984 Spacecraft Propulsion (Spring, Sr Year) • Senior Propulsion (5135) is prerequisite Out-of-department technical electives (only 1 counts) ECPE 4164 Intro to GPS Theory/Design (Fall, any year) GEOG 4354 Intro to Remote Sensing (Fall, any year) • Recommend taking by junior year PHYS 3655/3656 Intro to Astrophysics (Fall/Spring) • Recommend taking by junior year C. Hall, Randolph 224D cdhall@vt.edu

  6. Research Opportunities(juniors and seniors) • Satellite Tracking Laboratory • operational in Randolph 311A • need software tools for using the lab with astronautics courses • Spacecraft Simulator Laboratory • under development in Hancock 214 • need help integrating software and hardware • Take variable hours AOE 4994 • Present paper at AIAA Student Conference C. Hall, Randolph 224D cdhall@vt.edu

  7. Amateur Satellite Tracking Station Operational in 311A Randolph Hall Allows tracking and communications with amateur satellites, Space Shuttle, and HokieSat This picture was made using the freeware program WinOrbit. C. Hall, Randolph 224D cdhall@vt.edu

  8. b3 b2 b1 Spacecraft Simulator Laboratory • In Hancock 214 • Spherical Air Bearing simulates torque-free environment • Experiments complement analytical research funded by Air Force and NASA on Spacecraft Formation Flying • Facility will be used in research on magnetic bearings on moving platforms C. Hall, Randolph 224D cdhall@vt.edu

  9. Space Jobs • Interns: summer jobs at Orbital, Goddard, Intelsat, ... • Co-op: long-term semester-at-a-time jobs at … • Contact: Catherine Copeland in Career Services • Finding a permanent position • Space graduates are working at Aerospace Corp, Ball, Lockheed-Martin, Goddard, Kennedy, Langley, Johnson … • www.spacejobs.com C. Hall, Randolph 224D cdhall@vt.edu
