19 April - Satellite Aryabhata

 

Aryabhata was India's first satellite,named after the famous Indian astronomer.Aryabhata was launched on April 19, 1975, from the Kapustin Yar launch site in the Soviet Union (now Russia), using a Soviet Kosmos-3M launch vehicle. The satellite was developed by the Indian Space Research Organisation (ISRO) and marked India's entry into the realm of space exploration.

The satellite was primarily intended for conducting scientific experiments in X-ray astronomy and solar physics. It played a crucial role in enhancing India's capabilities in space research and laid the groundwork for subsequent satellite missions undertaken by ISRO.

While Aryabhata was India's first indigenously built satellite, it wasn't the first satellite to be launched by India. That honor goes to the satellite named "Rohini," which was launched aboard a Satellite Launch Vehicle (SLV) on July 18, 1980. However, Aryabhata remains a significant milestone in India's space program and is remembered for its contribution to the country's advancements in space technology.

19 April - Charles Darwin death anniversary

 

Charles Darwin, passed away on 19 April 1882, was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.
