Review Questions

• How did the launch of Sputnik 1 impact the development of satellite technology?
  • The launch of Sputnik 1 in 1957 marked a pivotal moment in satellite technology as it was the first artificial satellite to orbit Earth. This event not only ignited the space race between the United States and the Soviet Union but also spurred significant investments in space exploration and technology. Following Sputnik's success, both nations focused on developing more advanced satellites for various purposes, including communication and reconnaissance, leading to rapid advancements in satellite capabilities that continue to influence our daily lives today.
• Discuss the role of satellite technology in modern communication systems and its implications for global connectivity.
  • Satellite technology plays a critical role in modern communication systems by providing reliable connectivity over vast distances. It facilitates telephone calls, television broadcasts, and internet access, especially in remote or underserved areas where traditional infrastructure is lacking. The ability to connect people across the globe has transformed how information is shared and consumed, fostering greater social interaction and economic development while also raising concerns about security and privacy in our increasingly interconnected world.
• Evaluate the ethical considerations surrounding the use of satellite technology for surveillance purposes and its effects on privacy rights.
  • The use of satellite technology for surveillance raises significant ethical considerations regarding privacy rights and government accountability. While satellites can enhance national security and aid in disaster response, their capability to monitor individuals without consent poses serious implications for civil liberties. As satellite imagery becomes more accessible and detailed, debates around privacy infringement intensify. The challenge lies in balancing the benefits of enhanced security with protecting individual freedoms, necessitating clear regulations and oversight to govern the use of such powerful technology.
