Upon What Does the Turtle Stand? : Rethinking Education for the Digital Age
Brings together the reflections of independent researchers from around the world. Sixteen authors from fourteen countries present their views on the use of information and communication technology (ICT) in education, offering valuable insights through the examination of current issues relevant to the future of education. What will education be in tomorrow’s world? How can ICT be used without rendering education a purely technical process? How can we succeed the renovation of educational subjects without transforming them into technical objects? The introductory chapter of this publication guides us into the essays through a classification organized by the editors to illustrate different attitudes to technologies: The ‘Globalizers’ see the integration of ICT and education as a means of enhancing the competitiveness of their society in a global economy / The ‘Reformists’ see it as a means of bringing about significant change in didactics in the various disciplines, and even in the ‘basics’ of education / The ‘Humanists’ consider technologies as possible catalysts for changing the aims and values of education from learni- oriented to humanistic

Space Systems Failures : Disasters and Rescues of Satellites, Rocket and Space Probes
The very first book on space systems failures written from an engineering perspective. In the 1960s and 1970s deep space missions were dispatched in pairs in case one was lost in launch or failed during its journey. Following the triumphs of the Viking landings on Mars in 1976 and both Voyagers spacecraft successfully surveying the outer giant planets of the Solar System, it was decided by NASA to cut costs and send out just a single probe. Although Magellan successfully mapped Venus by radar, it suffered from problems during the flight. Then came the loss of Mars Observer, whose engine exploded as it was preparing to enter Mars’ orbit because it was using technology designed for Earth’s satellites and the engine was not suited to spending several months in space. Later came the high-profile losses of Mars Climate Observer and Mars Polar Lander - a consequence of the faster, better, cheaper philosophy introduced by Dan Goldin in 1993. Even the highly successful Galileo mission suffered a major setback when its high-gain antenna (also based on satellite mission suffered a major setback when its high-gain antenna (also based on satellite communication technology) failed to deploy fully, greatly diminishing the craft’s radio transmission capabilities, forcing the ground crew to re-programme the on-board computer to enable it to fulfil its mission and provide stunning images of Jupiter and its moons.

Messages security application
The rapid development of communication technology, is bringing many technological conveniences with it and simplifying our lives. On the other hand, it has disadvantages such as hiding the information that is continuously roaming through various communication media resources between senders and receivers and avoid sharing them with third parties. Eliminating these disadvantages via specific security methods and algorithms is related to the discipline called cryptography, which includes information security. Encryption is the process of turning a plaintext to jargon or the method of changing a confidential file to jargon in order to prevent unauthorized persons from gaining access to confidential message. A Message is the transfer of information from the sender to the receiver through a particular medium. Encryption is the most effective process for achieving data security.
