SUMMARY: The comet-chasing spacecraft Rosetta has been given a new comet to chase: Comet Churyumov-Gerasimenko. The European Space Agency announced on Wednesday that the spacecraft will now be launched in February 2004, and it will rendezvous with the comet in November 2014. Rosetta was originally supposed to launch earlier this year, but it was delayed after an Ariane 5 rocket failed to launch its satellite payload - Rosetta was held back to give investigation teams time to determine what called the failure, and lost its launch window for Comet Wirtanen.
