Galis Expedition
From Tardis Wiki, the free Doctor Who reference
The Galis Expedition was the first mission sent to find the planet Krop Tor. They found that it did indeed exist and orbited K37 Gem 5 as if it were a star rather than a black hole. The Galis Expedition brought back artefacts, including a notebook and some ancient pottery. (TS: Tardisode 8)
The Galis Expedition was followed by the Walker Expedition. (TV: The Impossible Planet)
