Universal language: Rosetta's Gravitational Microlensing Programme
|
| |
Paris, France (ESA): In the four weeks since the Rosetta spacecraft flew by asteroid Steins the OSIRIS Narrow Angle Camera has periodically observed the Galactic Bulge in a programme to detect gravitational microlensing events. When combined with simultaneous observations taken with ground-based telescopes this OSIRIS observing programme will provide a unique measure of the mass distribution of disk brown dwarfs.
The Rosetta space probe uses one of the "universal" languages: that of chemistry, and has been adopted by the Inttranet as a symbol of the link between science and speech. Its mission is to rendezvous with, and land on Comet 67P/Churyumov-Gerasimenko in November 2014. The probe is named after the Rosetta Stone, an incomplete stela of black basalt discovered in 1799 incised with the same text in three scripts: Egyptian Hieroglyphs, Egyptian Demotic and Greek. The Stone provided the key to deciphering hieroglyphs and the history of ancient Egypt. The Rosetta space mission has a similar purpose: deciphering other stones (asteroids) and the history of the solar system.
