From the Vega mission to comet Halley to the Rosetta mission to comet 67/P Churyumov-Gerasimenko

Zelenyi, L. M.; Ksanfomality, L. V.

The data acquired by the Vega and Giotto spacecraft, while investigating comet 1P/Halley in 1986, are compared to the results of the first phase of exploration of the nucleus of comet 67P/Churyumov-Gerasimenko performed with the Rosetta and Philae modules. The course of the Rosetta mission activity and the status of the modules after the Philae pr…
