Descriptive Annotation: Mission to Mars is written in a way that makes the reader feel as if the author is walking you through what it would be like to travel through Mars. It goes step by step as to what it would be like on your way there, what living in the space shuttle is like and what you would need to do once you actually landed in Mars. What I find neat about this book is that it presents facts on Mars, but they are incorporated in the way the author describes how the mission to Mars to be. It is fun because it is a non-fiction book but it reads and looks a lot like a picture book. Interdisciplinary Connections: This book would be great to connect to science when learning about planets. In particular Mars, since that is the main idea of the book.
A Review of Antennas for Picosatellite Applications
satellite communication | Definition, History, & Facts | Britannica
Cube Satellite CubeSat technology is an attractive emerging alternative to conventional satellites in radio astronomy, earth observation, weather forecasting, space research, and communications. Its size, however, poses a more challenging restriction on the circuitry and components as they are expected to be closely spaced and very power efficient. One of the main components that will require careful design for CubeSats is their antennas, as they are needed to be lightweight, small in size, and compact or deployable for larger antennas. This paper presents a review of antennas suitable for picosatellite applications.
Race is on to make satellites that generate, transmit solar power
A novel MIMO multiple input multiple output satellite channel model that allows the generation of associated channel impulse response CIR time series depending on the movement profile of a land mobile terminal is presented in this paper. Based on high precise wideband measurements in L-band the model reproduces the correlated shadowing and multipath conditions in rich detail. The model includes time and space variant echo signals appearing and disappearing in dependence on the receive antenna position and movement, and the actual azimuths and elevations to the various signal sources. Attenuation and path delays relative to the hypothetical line of sight LOS ensure usability for ranging purposes. Parameters for car and pedestrian applications in urban and suburban environments are provided.
The title is a bit misleading. The tale of how President Eisenhower brought imagery intelligence into the heart of US defense policy making is an excellent case study on how a President should deal with a lack of critical information. How and why the early Corona spy satellites were designed and built should stand with the Ultra code-breaking story as one of the most important Western espionage achievements of the last century. One, therefore, expects bits of their dogma to be included in this work.
