In 'Will you take my hand', the season 1 finale of Discovery, we have the Discovery jumping into a cave on the Klingon homeworld, under the surface as part of Starfleet's insane plan to infiltrate and then blow up the Klingon homeworld.
However, in the TNG episode 'The Pegasus', Data is uncertain of taking the Enterprise NCC-1701-D into an asteroid. He says, "I am unaware of any prior situations where a starship was taken so deeply inside a planetary body. There may be unforeseen difficulties."
Are there any explanations? Was Discovery's spore drive and activities still classified up till TNG's timeframe? Or Data isn't well-versed in Starfleet history?
