Satellites are becoming as useful as any other global infrastructure. The main three application: imaging, communications and navigation are expanding very fast paving the way for the "New Space" firms bringing space tourism, space minerals excavation and space fueling to become a reality for humanity

  • מה זה בעצם לווין תקשורת - בקצרהלוויני התקשורת נמצאים גבוה מעל כדור-הארץ. גובה של 36000 ק"מ מעלינו. הם נעים במהירות כזו שעוקבת אחר מהירות סיבוב כדור-הארץ כך שלצופה על הקרקע הם נראים כנקודה עומדת בשמיים. עומד. נייח. סטציונרי משמעו נייח לא זז. גיאוסטציונרי – נייח מול כדור-הארץמגלל שהם לא זזים הם מצוינים כתחנות ממסר של תקשורת ביו יבשות ובתוך איזורים גדולים על כדור-הארץ. למדינת ישראל הוקצתה הנקודה 4 מעלות מערב מהאפס. נקודת גריניץ' שליד לונדון. שם נמצאים לוויני עמוס-2 ועמוס-3. בעמוס-5 אנחנו למעשה מתרחבים לנקודה חדשה בשמיים – 17 מעלות מזרח.

  • This illustration released by The Defense Advanced Research Projects Agency (DARPA) showing a satellite used for DARPA's Phoenix program scavenging defunct communication satellites for their valuable parts and recycling them to build brand new ones. It's the latest pet project from the Pentagon's research wing known for its quirky and sometimes out-there ideas. The Defense Advanced Research Projects Agency is spending $180 million to test technologies that could make this possible. (AP Photo/DARPA) (The Associated Press)
