A gas giant in whose turbulent atmosphere the science vessel USS Raman became trapped in 2370, leading La Forge to explore the ship through a remote probe interface.
Marijne VII is a gas giant planet featured in the seventh-season Next Generation episode Interface.
In 2370 the Starfleet science ship USS Raman sinks into the planet's atmosphere and its crew are killed. Conditions are far too dangerous for an away team, so La Forge uses an experimental interface that connects his VISOR inputs directly to a probe, letting him see and feel as though he were walking the Raman's decks himself.
Geordi has just been told that his mother's ship, the USS Hera, is missing. Aboard the Raman he meets a figure who appears to be Captain Silva La Forge and begs him to take the ship lower. She is really one of a group of subspace beings native to the lower atmosphere, who were carried upwards by accident and are dying. Geordi guides the Raman down far enough to return them home.
