Giovanni Schiaparelli and the Martian Canals

On March 14, 1835, Italian astronomer and science historian Giovanni Schiaparelli was born. He is remembered best for his observations of planet Mars, where he discovered a dense network of linear structures on the surface of Mars which he called “canali” in Italian, meaning “channels” but the term was mistranslated into English as “canals” indicating that the observed structures should be of artificial origin. Early Years Schiaparelli graduated in 1854 from the…

Lost on Mars – The Ill Fate of the Beagle 2 Space Mission

On February 11, 2004, the British Mars landing spacecraft Beagle 2 that formed part of the European Space Agency’s 2003 Mars Express mission was abandoned due to all contact with it was lost. “HMS Beagle was the ship that took Darwin on his voyage around the world in the 1830s and led to our knowledge about life on Earth making a real quantum leap. We hope Beagle 2 will do the same thing for…

Mariner 4 and the First Pictures from Mars

On July 15, 1965, NASA spaceprobe Mariner 4 performed the first successful flyby of the planet Mars, returning the first pictures of the Martian surface. It captured the first images of another planet ever returned from deep space; their depiction of a cratered, seemingly dead world largely changed the view of the scientific community of life on Mars. Failed Trials The two Soviet probes Marsnik 1 and 2 were launched in October 1960…

Alfred Nier – a Pioneer in Mass Spectroscopy

On May 28, 1911, American physicist Alfred Otto Carl Nier was born. Nier pioneered the development of mass spectrometry. He was the first to use mass spectrometry to isolate uranium-235 which was used to demonstrate that 235U could undergo fission and developed the sector mass spectrometer configuration now known as Nier-Johnson geometry. Alfred Otto Carl Nier attended the University of Minnesota and graduated in electrical engineering in 1931. Nier decided to continue…

Donald Howard Menzel and the UFOs

On April 11, 1901, theoretical astronomer and astrophysicist Donald Howard Menzel was born. Menzel discovered the physical properties of the solar chromosphere, the chemistry of stars, the atmosphere of Mars, and the nature of gaseous nebulae. Moreover, he was best known for his arguments against the existence of extraterrestrial UFO‘s. Early Years Donald Howard Menzel already collected rocks as a child and built a chemistry laboratory in the cellar of his family’s…

Mariner 9 – The first Spacecraft to reach another Planet

On November 14, 1971, U.S. spacecraft Mariner 9 was the first spacecraft to orbit another planet – only narrowly beating the Soviets’s Mars 2 and Mars 3, which both arrived within a month. After months of dust storms it managed to send back clear pictures of Mars’ surface. Mariner 9 was designed to continue the atmospheric studies and map over 70% of the Martian surface from the lowest altitude of 1500 kilometers and…

Asaph Hall’s Achievements in Astronomy

On October 15, 1829, American astronomer Asaph Hall III was born, who is most famous for having discovered the moons of Mars, Deimos and Phobos, in 1877. He determined the orbits of satellites of other planets and of double stars, the rotation of Saturn, and the mass of Mars. Asaph Hall was born in Goshen, Connecticut and due to the early death of his father, Hall had to leave school at the…

Viking 1 and its successful Mission to Mars

On August 20, 1975, NASA spacecraft Viking 1 was launched and sent to Mars. The Viking program was was the most expensive and ambitious, but also highly successful mission ever sent to Mars. The Viking spacecraft was composed of two main parts: an orbiter designed to photograph the surface of Mars from orbit, and a lander designed to study the planet from the surface. Moreover, I remember the exciting messages in the…

Allan Hills 84001 and Is There Life on Mars?

Allan Hills 84001 and Is There Life on Mars?

Allan Hills 84001 (commonly abbreviated ALH 84001) is a meteorite that was found in Allan Hills, Antarctica on December 27, 1984 by a team of U.S. meteorite hunters. What makes it so special that it is responsible for worldwide headlines on August 6, 1996, when NASA scientists announced that it might contain evidence for microscopic fossils of Martian bacteria based on carbonate globules observed. A Meteorite from a “Wet” Mars ALH84001 is a meteorite thought to…
