Valentina Tereshkova (06 Mar 1937)
She was a Soviet cosmonaut who was the first woman to fly in space. She is the only solo woman. She was selected as a cosmonaut for her expert skill in parachuting. She was the only one of the four-woman participants to complete a space mission. On 16 Jun 1963, she was launched in Vostok 6 and made 48 orbits of Earth in 71 hours. Tereshkova left the program shortly after her return. She was also honored with the title Hero of the Soviet Union.
Joseph von Fraunhofer (6 Mar 1787 - 7 Jun 1826)
He was a German physicist who first studied the dark lines in the solar spectrum, which were seen by Wollaston in 1802. He measured 576 lines but could not explain them. These are caused by the selective absorption of those wavelengths by atoms of elements. He used a diffraction grating instead of a prism to disperse the spectrum. He also invented a heliometer.
Johann Georg Hagen (6 Mar 1847 - 5 Sep 1930)
He was an Austrian Jesuit priest and astronomer who made a catalog of variable stars. He worked at the Vatican Observatory and reexamined for accuracy the listing of all the NGC (New General Catalogue of Nebulae and Star Clusters) objects north of about -30 degrees. He published lists of errata in the NGC. During his observations, he observed tenuous dark clusters of interstellar matter. These strange clouds have not been recorded by others. Jesuits have been involved in astronomy since 1551.

Hans Albrecht Bethe (2 Jul 1906 - 6 Mar 2005)
He was a German-American physicist who helped to shape classical physics into quantum physics. He also increased the understanding of the atomic processes responsible for the properties of matter and of the forces governing the structures of atomic nuclei. He studies nuclear reactions and reaction cross-sections. In 1943, he was asked to be the head of the Theoretical Division at Los Alamos on the Manhattan Project. He also received the Noble prize for physics (1967) for his work on the production of energy in stars.

Niels Bohr's Model of the Atom
On this day in 1913, Niel Bohr described his new ideas on the atomic structure in his first paper. It was one of the three historic papers he wrote on this subject.
Dawn spacecraft in Ceres orbit
In 2015, the NASA spacecraft, Dawn, entered orbit around the dwarf planet, Ceres. It became the first spacecraft to orbit a dwarf planet. It travelled for 7.5 years covering 3100 million miles. On its way, it explored the giant asteroids and returned many images. As Dawn neared Ceres, it’s cratered surface showed some unusual small bright spots.
