  27. Anooshe Ansari • September 18, 2006 • First Female Private Space Explorer • the fourth private explorer to visit space • the first astronaut of Iranian descent

  28. Anooshe Ansari • Anousheh and her family provided title sponsorship for the Ansari X Prize, a $10 million cash award for the first non-governmental organization to launch a reusable manned spacecraft into space twice within two weeks

  29. Dr. Firouz Naderi • the associate director of NASA's Jet Propulsion Laboratory responsible for project formulation and strategy • the head of Mars Exploration Program

  30. Babak A. Tafreshi • photographer - science journalist • founder and director of The World At Night (TWAN) international photography project • member of Astronomers Without Borders • the 2009 Lennart Nilsson Award, the world's most recognized award for scientific photography, for his global contribution to night sky photography • 1997 to 2007 Tafreshi was an editor of the Astronomy Magazine of Iran (Nojum)

  33. The new Moon • sets in the early evening sky of Tehran • the head of Milad communication Tower • 435 m from base to the antenna tip

  34. Niloofar in Czech Republic IAC My paper

  35. Introduction Satellites Communication, Remote sensing, Planetary Exploration and Education LEO Less Weight & Size Less Cost of Manufacturing & Launch Attitude Control System – ACS Navstar54 35

  36. Stabilization & Attitude Control • Attitude Control • Reorientation & modification of the satellite attitude • Passive – Active • Gravity Gradient – GG • Spin Stabilized • Single spin • Dual spin • 3-axis stabilization • High accuracy pointing, Expensive, complicated, Heavy, Energy consuming • Momentum Exchange Device • Magnetic Control • Thrusters 36

  37. Modeling the Earth Magnetic Field • Carl Friedrich Gauss • A magnetic dipole 37

  38. Modeling the Earth Magnetic Field • The lack of electric surface current • Field as the gradient of a scalar potential • The absence of magnetic monopoles • Thus • Spherical nature of the boundary at the Earth’s surface • n=1: Dipole • n=2: Auardupole • n=3: Octupole • More coefficients  more accurate results 38

  39. Modeling the Earth Magnetic Field 10th generation of IGRF coefficients Up to 13 196 coefficients 39
