Bøger af Jason Hall

Would you marry someone in a wheelchair? I did. His name is Jason Hall, and this is our story.Everyone knew Jason's disability. He lived almost thirty-three years in a wheelchair. They all saw our hardships and hospital stays and barriers and obstacles. But the longer we lived, the more we understood that everyone has something. Everyone has a struggle to overcome. A heartbreak to heal. A tragedy to bear. A loss to feel deeply. A chance to persevere. We tried not to compare our pain with anyone else's. Everyone has to do the tough stuff.We started writing this book together - mostly his story but I was there too. Side by side. Planning and laughing and arguing about the best stories to tell. Remembering and thinking about what we have learned in life. Deciding the purpose. Focusing in on the message.And then Jason died.This is our story. It's full of people and moments that taught us things. We invite you to take it in. Because we want you to become a part of our story too.

The development and launch of the first artificial satellite Sputnik more than five decades ago propelled both the scientific and engineering communities to new heights as they worked together to develop novel solutions to the challenges of spacecraft system design. This symbiotic relationship has brought significant technological advances that have enabled the design of systems that can withstand the rigors of space while providing valuable space-based services. With its 26 chapters divided into three sections, this book brings together critical contributions from renowned international researchers to provide an outstanding survey of recent advances in spacecraft technologies. The first section includes nine chapters that focus on innovative hardware technologies while the next section is comprised of seven chapters that center on cutting-edge state estimation techniques. The final section contains eleven chapters that present a series of novel control methods for spacecraft orbit and attitude control.
