| Event Name: | Introduction to spacecraft and space environment effects on them |
| Event Description: | 6.30pm - 8.00pm This free public lecture is being held in conjunction with the Mars Society Australia. Several hundred spacecraft are in orbit around the Earth and a handful are exploring the solar system, so they have become part of everyday life in the last 50 years. The basics of spacecraft subsystems (e.g. communications, attitude control, power and thermal, sensors), orbits (geostationary (GEO), medium-earth (MEO) and low-earth (LEO)) and missions (communications, navigation, weather, remote sensing, reconnaissance) will be outlined in this talk. Spacecraft are also immersed in a high natural radiation environment that may be detrimental to their operation. The radiation environment at GEO, MEO and low-earth LEO orbits and their considerable variability will be described. Effects on spacecraft vary widely, such as Single Event Upsets caused by high-energy protons and Deep Dielectric Discharge or Electrostatic Discharge caused by high-energy electrons. The sources of the radiation in high-speed solar wind streams, solar particle events and geomagnetic storms will be described and examples of anomalies presented. |
