History of National Remote Sensing Day
The history of National Remote Sensing Day is closely tied to India’s space journey.
Why it is celebrated: It is observed on August 12, the birth anniversary of Dr. Vikram Sarabhai (1919–1971).
Who initiated it: The Indian Space Research Organisation (ISRO) and the Department of Space decided to mark this day to honor his immense contribution to India’s satellite technology and remote sensing program.
First Celebration: Official celebrations began in the late 1980s and early 1990s as India’s remote sensing satellites started operational work.
Dr. Sarabhai’s Vision: He believed India must harness space technology for nation-building, especially in agriculture, weather forecasting, and rural development. His vision led to the launch of India’s IRS (Indian Remote Sensing) satellite series.
What is Remote Sensing?
Remote sensing is the science of gathering information about the Earth’s surface without physically touching it—usually with satellites or aircraft.
It involves:
Satellite imagery
Aerial photography
Data interpretation using sensors
In simple terms, remote sensing is like having “eyes in the sky” to study Earth’s environment and resources.
