The stone, carved during the Hellenistic period, is believed to
Rosetta Stone part of the Launchpad project. Similarly, Rosetta@home is a distributed computing project for predicting protein structures from amino acid sequences (or "translating" sequence into structure). The Rosetta Project brings language specialists and native speakers together to develop a meaningful survey and near-permanent archive of 1,500 languages, intended to last from AD 2000 to 12,000. The European Space Agency's "Rosetta" spacecraft was launched to study a comet named 67P/Churyumov–Gerasimenko in the hope that determining its composition would reveal the origin of the Solar System.
