The probes were identical robotic spacecraft launched by Proton-K rockets with a Blok D upper stage, each consisting of an orbiter and an attached lander. After the Mars 2 lander crashed on the Martian surface, the Mars 3 lander became the first spacecraft to attain a soft landing on Mars, on December 2, 1971. It failed 110 seconds after landing, having transmitted only a gray image with no details. The Mars 2 orbiter and Mars 3 orbiter continued to circle Mars and transmit images back to Earth for another eight months.

Verghese Kurien (26 November 1921 – 9 September 2012), known as the "Father of the White Revolution" in India, was a social entrepreneur whose "billion-litre idea", Operation Flood,made dairy farming India's largest self-sustaining industry and the largest rural employment sector providing a third of all rural income.It made India the world's largest milk producer, doubled the milk available for each person, and increased milk output four-fold in 30 years.
He pioneered the Anand model of dairy cooperatives and replicated it nationwide, based on various "top-down" and "bottom-up" approaches, where no milk from a farmer was refused and 70–80% of the price by consumers was paid in cash to dairy farmers who controlled the marketing, procurement, and processing of milk and milk products as the dairy's owners.An invention at Amul was the production of milk powder from buffalo milk instead of from cow milk, which was in short supply in India.
He also made India self-sufficient in edible oils and fought against the "oil kings", who used underhanded and violent methods to enforce their dominance over the oilseed industry.
