Isro’s outreach programme was aimed at motivating young India and tapping their scientific potential. During the interaction the Isro Chairmen engaged with students on a series of topics ranging from rockets, satellites, Chandrayaan, Gaganyaan and other space applications.
Further, Isro will be organising guided tours thrice in a year, especially during summer and Christmas holidays for students of class 11 and class 12. The students would be taken to Isro facilities in Thiruvananthapuram and Bengaluru and the launch centre at Sriharikota.

Marathon: Roscosmos to venture into Internet of things (IoT) with the launch of new satellite system
Russia’s state space corporation (Roscosmos) has planned to venture into Internet of things (IoT) with launch of new satellite system named ‘Marathon’. The new satellite system will be part of Russia’s Sphere satellite constellation, which will be fully established by 2026. The number of satellites in Marathon system are not revealed yet. The federation’s GLONASS navigation, a satellite communication system and data relay satellite set-up will be other equipment in the constellation.
Russian President Vladimir Putin has approved Sphere constellation project, which involves the construction and deployment of 640 satellites. There are several segments of the satellite communication. USA’s Iridium has been long operating successfully on voice satellite communications market. OneWeb and Starlink dominate broadband Internet segment. IoT is the third segment of the satellite communication. Work in this segment will be successful if services are provided at lowest prices as the other systems also provide such services as well.
Internet of Things (IoT)
IoT is a network of devices such as smartphones, wearable devices, home appliances and vehicles, connected to internet, which enables these objects to connect and exchange data. Blockchain technology has potential to address security risks to IoT as it provides a shield against data tampering by labelling each block of data.
