Today in history. Some interesting events.
Historical events, as well as future historical events, such as spacecrafts journey.
Date: History events (sorted by year, month, day):
2006 September 15 Around mid September ESA (European Space Agency) will launch an Ariane 5 launcher (configuration ECA) (esa.int). with 3 satellites on board (DirecTV 9S, Optus D1 et LDRex 2). This version of Ariane 5 (ECA) is able to place payloads weighing up to 9.6 tonnes Into Geostationary Transfer Orbit.
Ariane 5, has originaly been developed to carry the European shuttle "Hermes" into orbit. It is a "human grade" launcher.

2006 September 9 STS-115 (wikipedia.org) Space Shuttle mission is the first to resume assembly of the International Space Station (ISS) following two "Return to Flight" test missions. The mission uses the Space Shuttle Atlantis.
2006 September 3 European space probe SMART-1 is expected to end its life in a scheduled crash on the moon surface. The SMART-1 impact (sci.esa.int) is expected in the Lacus Excellentiae region.

1979 September 1 Pioneer 11 (nssdc.gsfc.nasa.gov) passed by Saturn on September 1, 1979, at a distance of 21,000 km (about 13'000 miles) from Saturn's cloud tops.
Pioneer 11 has been use as a real "Pioneer" or a "guiney pig", it has been decided to have it pass through Saturn rings belt plan and see if it can make it, or have a better idea of the risk involved in the belt. This decision has been taken as Voyager 1 and 2 where in route to Saturn. Voyager 1 and 2 had already passed jupiter, they were in route to Saturn. Pioneer 11 scientific equipment and experiment were less sophisticate than Voyager 1 and 2, it has been decided to try with it first, to see if it can make it through the rings. It was use successfully to try a pass through the rings and observe what it might encounter.

The Pioneer 11 scientific Mission ended on 30 September 1995, in November, 1995 was the last communication with it. It was launched on 5 April 1973. The space craft antenna is out of alignement with earth, currently, it is not known if it still send signal to earth.
Pioneer 11 is heading toward the constellation of Aquila (The Eagle), Northwest of the constellation of Sagittarius. Its next close encounter with a star will be in about 4 million years.
Pioneer 11 is going away from the Sun at about 2.5 AU/year, or 12 km/s (about 7.5 miles/s).

Pioneer 10 is on its way to Aldebaran (the eye of the bull) in the Taurus constellation (the bull). It wil reach it in about 2 million years.

1859 September 1 Richard Christopher Carrington (hao.ucar.edu), the first solar flare seems to have been observed on this day. This event has also been witnessed by another person, sir Hodgson also member of the (British) Royal Astronomical Society. They independently submitted nearly identical sightings, from different locations.
(1826 May 26 - 1875 November 27). Son of a wealthy brewer, his father imposed him to study for a career in church. He studied and graduated from 1844 to 1848. Meanwhile, as soon as he could get away with it he did. He found a strong interest into astronomy and pursued it. He joined an observatory, later build his own. He observed by night and also by days.

Between 1854 and 1857, he worked on a "Catalogue of 3735 Circumpolar Stars". He received a gold medal (wikipedia.org) from the (British) Royal Astronomical Society.
However, he his remembered mostly for his work on Sunspots. He has been impressed by the work and discovery of a German astronomer: "Heinrich Schwabe", who in 1843 discovered the sunspots cycle. Richard Carrington choose to continue Heinrich Schwabe work. From 1853 to 1861 he recorded sunspots location. He missed the observation of a full sunspots cycle by a few years.

Sunspots obervation allowed him to dicover the differential rotation of the sun as well as the migration of spots in the course of a cycle. These two discoveries have been shared with another German astronomer Gustav Spörer (hao.ucar.edu).

Richard Carrington, also determined very accurately the Sun's rotation axis and made the first observation of a white light flare.

1846 September 23 AstronomerJohann Gottfried Galle (wikipedia) found Neptune. (1812 June 9 - 1910 July 10).
He was the first astronomer to have seen Neptune and used calculations made by a french mathematicien, Urbain Le Verrier (wikipedia). Neptune is the only planet discovered based on mathematical prediction rather than regular observations.
Galileo's astronomical drawings show that he had first observed Neptune on December 27, 1612, and again on January 27, 1613. Meanwhile both times he thought having found a fixed star.
Galle found the planet Neptune within 1 degree of Urbain le Verrier prediction.
Neptune discovery (wikipedia) had some controversy. Another mathematician from UK John Couch Adams (wikipedia), did some prediction about a year earlier, but both men where unaware of the work of each other. John Adams predictions were about 10 degrees off.
A conflict emerged between UK and France, regarding who discovered Neptune, Later it has been decided to give credit to both mathmaticians.
However, after some more in depth reading and some documents finding in 1998 (no error), it has been decided that Adams did not in fact deserve equal credit with Le Verrier (Scientific American).

About the Author

I am simply a Linux enthusiast with an interest in science.

I like to build hardware projects and connect them to computers, to do data acquisitions and other things. I also like to make telescopes or make existing telescopes more convenient to use.

This page will hopefully help me to learn something. I am happy if I can share it with the reader.

I belong to the following astronomy societies: RAS. ASOD and linuxastronomy.org, which is a virtual group of linux enthusiast, experimenting with astronomy.

Suggestions or corrections with for goal to make this site better are welcome.
