THIS DAY IN SPACE

Discovery of Makemake
On March 30, 2005, astronomers at the Palomar Observatory in California discovered Makemake, one of the largest known dwarf planets in our solar system. The discovery was made by a team led by Mike Brown, the same group that identified Eris and Haumea. Located in the Kuiper Belt beyond Neptune, Makemake is roughly two-thirds the size of Pluto and follows a highly inclined, elliptical orbit. Its surface is covered with methane ice, giving it a bright, reddish appearance. Initially known as 2005 FY9, the object was later named after the Rapa Nui god of fertility. The discovery of Makemake played a critical role in the reclassification of planets by the International Astronomical Union in 2006, leading to the definition of the term 'dwarf planet.' Alongside Eris and Haumea, Makemake's identification highlighted the diversity and richness of the Kuiper Belt and emphasized the need for a better understanding of small, icy bodies at the fringe of the solar system.

Launch of Luna 10, First Artificial Satellite of the Moon
On March 30, 1967, the Soviet Union launched Luna 10, which would go on to become the first human-made object to orbit the Moon. Part of the Soviet Luna program, this historic mission marked a major achievement in the space race, showcasing the USSR's continued leadership in lunar exploration following their earlier success with Luna 9. Luna 10 entered lunar orbit on April 3, 1967, and remained operational for about two months. During this period, it transmitted valuable data about the Moon's gravitational field, radiation levels, and surface composition. Remarkably, it also broadcast the communist anthem 'The Internationale' during the 23rd Congress of the Communist Party, making it a political as well as scientific milestone. Luna 10 demonstrated that sustained lunar orbit was possible and laid the groundwork for both robotic and future human missions. It remains a symbol of Cold War-era ambition and ingenuity in space exploration.
