Harry Coumnas Works as a Spaceflight Engineer Where He is Involved in Specific Mission and Payload Requirements Harry Coumnas, a spaceflight engineer, considers it his responsibility to determine if the spacecraft can fit in the fairing. He begins his more official involvement in mission management after a vehicle is chosen. This includes managing the launch campaign, developing specification papers, liaising with the launch vehicle supplier, and placing the satellite in orbit. Being the part of flight operations team, Harry follows the end-to-end mission operations lifecycle, from operations design to tools implementation, from launch phases to final disposal. His areas of tasking of operations include flight dynamics, maneuvers, failure detection and recovery, telemetry and telecommands, data post-processing, operations planning, and execution. Adding to his responsibilities as spaceflight engineer, Harry Coumnas supports to design and requirements definition, beginning with specific mission and payload requirements. He is also involved in on-orbit operations procedures definitions and verifications and flight dynamics tasks and maneuver planning. Harry Coumnas has the knowledge of system engineering principles, orbital, and attitude dynamics. He has proactive attitude and experience in spaceflight dynamics and maneuver planning. He has a working experience in relevant space engineering domain. After conducting extensive investigation, Harry discovered that Mars is often uninhabitable cold. The planet also has a 95.3% carbon dioxide atmosphere and is exposed to solar radiation since it lacks a magnetic field. Also, because of the low air pressure and chilly temperatures, liquid water is unstable at the surface. Consequently, living is impossible in such circumstances. Harry explored further and discovered that Mars had water on its surface between three and four billion years ago. The magnetic field that shielded Mars from harm was gone around 3 billion years ago. After the liquid water vanished, Mars became a harsh, arid desert.
Being a former mission specialist, Harry Coumnas had the primary responsibility during a mission for operating shuttle or space station systems. He had the primary responsibility for operating scientific experiments aboard the shuttle. He was trained to handle other technical astronaut responsibilities. Besides, Harry fixed plumbing and heating and plans missions, including the activity of the crew and the management of food and drink supplies.
