Watch Rosetta landing site selection announcement

Since ESA's Rosetta spacecraft arrived at Comet 67P/Churyumov-Gerasimenko on 6 August, the race has been on to find a suitable location for the lander Philae. Five candidate locations were announced on 25 August for further investigation, in order to determine possible orbital and operational strategies for Rosetta to despatch the lander to each of them. By 14 September, the five candidate sites will have been assessed and ranked, leading to the selection of a primary landing site and a backup. The final two sites, along with their operational challenges and scientific expectations, will be presented during the briefing on 15 September.

Watch live as the target for Rosetta's lander is announced at ESA Headquarters on 15 September, streaming starts at 0900 GMT / 1100 CEST.
