The year 2009 in science involves some significant events.
2009 has been designated as the:
Astronomy and space exploration
- January 26 – Annular solar eclipse.[2]
- February 24 – Comet Lulin, a non-periodic comet, makes its closest approach to Earth, peaking in brightness between magnitude +4 and magnitude +6.[3]
- March 7 – the Kepler Mission has a successful launch.[4]
- July 22 – Total solar eclipse (longest lasting total eclipse of the 21st century).[5]
- September 3 – Saturn's rings cross the plane of the earths orbit (Saturn is at equinox on August 2, marking the beginning of "spring" for Saturn's northern hemisphere). (The last crossing was May 22, 1995 and next will be on March 23, 2025)[6]
- December 31 – a partial lunar eclipse will be visible from all of Africa, Europe, Asia, and Australia.[7]
Science
- May 19 – Paleontologists announce the discovery of Darwinius masillae, a "missing link" with features similar to lemurs, monkeys, and humans.[8]
- October 1 – Paleontologists announce the discovery of an Ardipithecus ramidus fossil skeleton, deeming it the oldest fossil skeleton of a human ancestor.
- December 31 – The Sleeping Beauty Transposase SB 100X is the Molecule of the Year 2009 as announced by Isidro T. Savillo, President of the International Society for Molecular and Cell Biology and Biotechnology Protocols and Researches (ISMCBBPR) (Scientist Solutions) (MDC Berlin-Buch) (VIB K.U.Leuven)
Scheduled events
Scientific events scheduled to occur in the year 2009 include:
- February 1 - The International Cospas-Sarsat Satellite System is scheduled to stop monitoring for 121.5 MHz and 243 MHz (Class B) distress signals from EPIRBs and other emergency beacons.
- May 11–22 - STS-125, the last expected Space Shuttle mission to service the Hubble Space Telescope.
- September 29 - NASA's MESSENGER spacecraft makes its final flyby of Mercury, decreasing velocity enough for an orbital capture in 2011.
Deaths
- February 11 - Willem Johan Kolff (b. 1911), physician, inventor of artificial organs.
