Indian Space Research Organization has adopted a new logo which "is vibrant, dynamic and symbolizing a lot of energy and vitality".
In the new logo, a satellite is depicted through the two solar arrays providing energy and a pointed arrow reaching upwards signifies the launch vehicle for exploring new heights, searching the realms (kingdom) of space.
The logo also visually depicts the upward mobility of Isro with the arrow shooting upwards conveying that it can break all barriers, be it gravity or mindsets, according to the latest edition of 'Space India', the official journal of ISRO.
The name ISRO is written in Devnagari and English with the latter in a stylized font called 'Prakrta' resembling the Devnagari script to create a balance in design.
The colours used are Orange and Blue.
"In summary, the new logo depicts (show) the ambitions and aspirations of ISRO in the realm of space", the journal adds.
| About ISRO The Indian Space Research Organisation (ISRO, Bhartiya Antariksa Anusandhana Sangathana) is an independent Indian governmental agency established in 1969 for the research and development of vehicles and activities for the exploration of space within and outside of Earth’s atmosphere. Headquartered in Bangalore (Bengaluru). ISRO’s chief executive is a chairman, who is also chairman of the Indian government’s Space Commission and the secretary of the Department of Space. ISRO’s first satellite, Aryabhata, was launched by the Soviet Union in 1975. Rohini, the first satellite to be placed in orbit by an Indian-made launch vehicle (the Satellite Launch Vehicle 3) was launched in 1980. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle for putting satellites into polar orbit and the Geostationary Space Launch Vehicle for placing satellites into geostationary orbit. These rockets have launched communications satellites, Earth-observation satellites, and, in 2008, Chandrayaan-1, India’s first mission to the Moon. ISRO plans to put two astronauts into orbit in 2015. Space activities in the country started during early 1960s with the scientific investigation |
of upper atmosphere and ionosphere over the magnetic equator that passes over Thumba near Thiruvananthapuram using small sounding rockets Realising the immense potential of space technology for national development, Dr. Vikram Sarabhai, the visionary leader envisioned that this powerful technology could play a meaningful role in national development and solving the problems of common man.

Thus, Indian Space programme born in the church beginning, space activities in the country, concentrated on achieving self reliance and developing capability to build and launch communication satellites for television broadcast, telecommunications and meteorological applications; remote sensing satellites for management of natural resources.
The objective of ISRO is to develop space technology and its application to various national tasks. Accordingly, Indian Space Research Organisation (ISRO) has successfully operationalised two major satellite systems namely Indian National Satellites (INSAT) for communication services and Indian Remote Sensing (IRS) satellites for management of natural resources; also, Polar Satellite Launch Vehicle (PSLV) for launching IRS type of satellites and Geostationary Satellite Launch Vehicle (GSLV) for launching INSAT type of satellites.
The Space Commission formulates the policies and oversees the implementation of the Indian space programme to promote the development and application of space science and technology for the socio-economic benefit of the country. DOS implements these programmes through, mainly Indian Space Research Organisation (ISRO), Physical Research Laboratory (PRL), National Atmospheric Research Laboratory (NARL), North Eastern-Space Applications Centre (NE-SAC) and Semi-Conductor Laboratory (SCL). The Antrix Corporation, established in 1992 as a government owned company, markets the space products and services
Indian space programme driven by vision of Dr Vikram Sarabha considered as the father of Indian Space Programme. There are some who question the relevance of space activities in a developing nation. To us, there is no ambiguity of purpose. We do not have the fantasy of competing with the economically advanced nations in the exploration of the moon or the planets or manned space-flight. But we are convinced that if we are to play a meaningful role nationally, and in the comity of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.

ISRO plans to put two astronauts into orbit in 2015. It took around 20- 25 minutes. The panel is having 9 or 10 scientist. The senior scientist sitting at the middle asked most of the questions. We will be standing in front of a board where we have to draw diagrams if asked. I remember some of the questions. > Shamsudheen, which subject you have prepared? -communication engineering. He asked many questions from transmission line characteristics, stub matching, wave guides, etc. I said what these things are. But he asked to tell basic concepts like why there is only TE or TM mode in wave guide and not TEM. I know very little about transmission lines. I asked him to change the topic. Then they asked questions generally from electronics basics like > what is modulation? > different kinds of modulation > draw the circuit if demodulator > what is the output of not gate for sine wave input? > how to shift a sine wave up or down? > different kinds of modulation They asked about my project.I did my project in Wipro technologies, Basically it is a java based application to control multi-functional printer networks. Maybe because, it is in java they didn’t ask questions from the project. Also they asked if I have any other offer and in which company. I said bosch. Basic electronics,microcontrolls,lic,network thery so ALL THE BEST |
