●Satish Dhawan SAT (SDSAT)is built by Space Kidz India.
●SDSAT is a nano satellite intended to study the radiation levels/space weather and demonstrate long range communication

●UNITYsat, the combination of ‘3 Satellites’ designed and built as a Joint Development by Jeppiaar Institute of Technology, Sriperumpudur (JITsat), G. H. Raisoni College of Engineering, Nagpur (GHRCEsat) and Sri Shakthi Institute of Engineering and Technology, Coimbatore (Sri Shakthi Sat).
●The ground stations located at Chennai, Nagpur and Coimbatore will be a network for monitoring the UNITYsat in orbit which will be launched by PSLV C51.
●UNITYsat is intended for providing Radio relay services.

●The PSLV-C51 is the 53rd mission of the Indian Polar Satellite Launch Vehicle (PSLV) program.
●The Polar Satellite Launch Vehicle (PSLV)-C51 was launched at 04:54 (UTC) / 10:24 (IST) on 28 February 2021 with the main payload from Brazil, INPE’s Amazônia-1 and 18 other ride-sharing small satellites.
●This is the first dedicated commercial launch executed by NSIL.
●The PSLV C51 rocket has four stages; each one was self-contained, with its own propulsion system, thereby capable of functioning independently.
●The first and third stages used composite solid propellants, while the second and fourth stage use earth-storable liquid propellant.

Meghananda Saha
●Meghnad Saha was an Indian astrophysicist who developed the Saha ionization equation, used to describe chemical and physical conditions in stars.
●His work allowed astronomers to accurately relate the spectral classes of stars to their actual temperatures.
●He was elected to the Parliament of India in 1952. 
●Sathyendranath Bose was his classmate and Saha also participated in Swadeshi movement.

●Technical Education Quality Improvement Programme is a project of Government of India assisted by World Bank.
●The project was implemented to improve the quality of education in the technical institutions of India. 

●To boost for the country’s surveillance capabilities to monitor activities of both military warships and merchant shipping in the Indian Ocean Region (IOR).
●The ‘Sindhu Netra’ satellite developed by a team of young scientists from Research and Development Organisation (DRDO) was successfully deployed in space on Sunday.
●It is capable of automatically identifying the warships and merchant ships operating in the IOR. 
●The satellite, if required, can also help in carrying out surveillance in specific areas such as the South China Sea or the pirate-infested areas near the Gulf of Aden and the African coast.
●Sindhu Netra is one of the first in the series of satellites that would help the nation in enhancing its surveillance capabilities on land in areas such as the Ladakh region with China and the border areas with Pakista
