Explanations:The concept of CubeSat satellites is an important aspect of modern space technology. CubeSats are small satellites that are typically used for educational, research, and technological demonstration purposes. They are often developed by universities, research institutions, and smaller countries to conduct experiments and gather data in space. The size and cost-effectiveness of CubeSats make them an attractive option for countries that are new to space technology or wish to engage in space research without the high costs associated with larger satellites.
Collaborative space missions involving CubeSats are becoming increasingly common as countries seek to share the costs and expertise required for space exploration. These collaborations can involve countries of varying sizes and levels of technological development. For example, a smaller country like Nepal can partner with another smaller country like Sri Lanka to launch a CubeSat, thereby gaining valuable experience and data from space missions without the need for extensive national space programs.
In the context of the question, the correct answer is that Nepal and Sri Lanka have launched a CubeSat satellite together. This collaboration is significant because it represents a growing trend of smaller countries working together in space technology. Such partnerships can lead to shared knowledge, reduced costs, and increased access to space for countries that might otherwise find it difficult to participate in space missions independently.
It is important to note that while major space powers like India, Russia, Japan, China, and the United States have extensive space programs and have collaborated on various missions, the specific collaboration involving a CubeSat satellite launch is between Nepal and Sri Lanka. This partnership highlights the evolving landscape of space exploration, where smaller countries are increasingly participating in space activities through collaborative efforts.
