Hollerith's invention automated the counting and sorting of information by encoding data on punched cards read by electromechanical machines. Initially developed for the 1890 U.S. Census, the technology reduced processing time from years to months. Hollerith founded the Tabulating Machine Company, which later evolved into IBM. His work laid the groundwork for modern computing by introducing systematic data encoding, storage, and retrieval. The punched card system dominated information processing well into the mid-20th century.

On January 8, 1973, the Soviet Union launched Luna 21 from the Baikonur Cosmodrome as part of its robotic lunar exploration program. The mission carried the Lunokhod 2 rover, designed to traverse the lunar surface and transmit scientific data back to Earth. Luna 21’s successful deployment allowed the rover to cover over 37 kilometers on the Moon, far surpassing its predecessor Lunokhod 1 in range. The rover conducted soil analysis, captured high-resolution images, and measured the lunar environment’s temperature and radiation. Luna 21 remained operational for about four months, providing valuable insights into the Moon’s geology and conditions. This mission demonstrated the Soviet space program’s technological prowess during the height of the Space Race. Luna 21’s achievements contributed to humanity’s understanding of Earth’s natural satellite.

On January 8, 1994, Soviet cosmonaut Valeri Polyakov departed Earth aboard Soyuz TM-18. He began a continuous stay on the Mir space station that would last until March 22, 1995. Polyakov orbited Earth for a record-breaking 437 days to study the effects of long-duration spaceflight on the human body. He conducted medical experiments to understand muscle atrophy, bone density loss, and radiation exposure. His mission provided invaluable data for planning future missions to Mars and beyond. Polyakov returned safely, breaking previous spaceflight duration records and inspiring space medicine research.
