The global space market is shifting towards lightweight, affordable and available space systems: smaller instrumentations, dual-use systems, assembly line payloads, constellations and flight formation. This trend gives rise to Micro and Nano satellites. The Israeli space program, originally motivated by national-security needs and lack of resources, had to focus on miniaturization. The Israeli space industry and academia developed know-how and technological infrastructure in the field of small satellites to fulfill these needs and requirements. Today, Israel specializes in developing lightweight, high-resolution, high precision small satellites for both national security and scientific needs, and has unique expertise in these areas. Based on this technological know-how several Israeli groups are currently developing micro-satellites and nano-satellites for demonstrating and validating new-technologies, and technology spin-ins. An additional outcome of these activities is educational public outreach for inspiring young people to pursue their future in the space business. This paper focuses on two activities reflecting on this process. First, it presents microsatellites projects such as Venus, a joint Israeli-French satellite for scientific and technological missions. Second, it depicts Inklajnl nano-satellite project, involving high school students in the development process. These fields of expertise, at the head of current global trends, are opportunities for international joint ventures, for example in the field of Earth Observation, for better use of global resources.
