<P> The series follows the fortunes of Dave Lister who is stranded three million years in the future, together with the hologrammatic representation of his former bunkmate and immediate superior Arnold Rimmer; a creature known only as Cat; and the ship's computer Holly . During Series II, the crew encounter a mechanoid called Kryten, who joins them from Series III onwards . In Series VI the Red Dwarf ship has been stolen from the crew, forcing them to travel in the smaller Starbug craft for two series . In Series VII Kristine Kochanski, Lister's former love interest, joins the crew, following the departure of Rimmer . In series VIII the entire crew of the Red Dwarf ship--including a pre-accident Rimmer--are resurrected, but the Starbug crew, along with Rimmer, find themselves sentenced to two years in the ship's brig for "abusing classified information". Series IX (Red Dwarf: Back to Earth) involves Lister, Rimmer (back as a hologram), Cat, and Kryten hallucinating that they've arrived on Earth in another dimension in the early 21st century, and Series X and XI sees the same four crew members continue their adventures back on Red Dwarf, Kochanski having departed due to Lister's descent into depression and Holly offline due to water damage . </P> <P> The twelfth series of Red Dwarf premiered on 12 October 2017 on Dave . As of 16 November 2017, 73 episodes of Red Dwarf have aired . </P> <Table> <Tr> <Th_colspan="2"> Series </Th> <Th> Title </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 15 February 1988 (1988 - 02 - 15) </Td> <Td> 21 March 1988 (1988 - 03 - 21) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> II </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 6 September 1988 (1988 - 09 - 06) </Td> <Td> 11 October 1988 (1988 - 10 - 11) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> III </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 14 November 1989 (1989 - 11 - 14) </Td> <Td> 19 December 1989 (1989 - 12 - 19) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> IV </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 14 February 1991 (1991 - 02 - 14) </Td> <Td> 21 March 1991 (1991 - 03 - 21) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 5 </Td> <Td> V </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 20 February 1992 (1992 - 02 - 20) </Td> <Td> 26 March 1992 (1992 - 03 - 26) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 6 </Td> <Td> VI </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 7 October 1993 (1993 - 10 - 07) </Td> <Td> 11 November 1993 (1993 - 11 - 11) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 7 </Td> <Td> VII </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 17 January 1997 (1997 - 01 - 17) </Td> <Td> 7 March 1997 (1997 - 03 - 07) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 8 </Td> <Td> VIII </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 18 February 1999 (1999 - 02 - 18) </Td> <Td> 5 April 1999 (1999 - 04 - 05) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 9 </Td> <Td> Back to Earth </Td> <Td_colspan="2"> </Td> <Td_colspan="1"> 10 April 2009 (2009 - 04 - 10) </Td> <Td> 12 April 2009 (2009 - 04 - 12) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 10 </Td> <Td> X </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 4 October 2012 (2012 - 10 - 04) </Td> <Td> 8 November 2012 (2012 - 11 - 08) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 11 </Td> <Td> XI </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 22 September 2016 (2016 - 09 - 22) </Td> <Td> 27 October 2016 (2016 - 10 - 27) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 12 </Td> <Td> XII </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 12 October 2017 (2017 - 10 - 12) </Td> <Td> 16 November 2017 </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Series </Th> <Th> Title </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr>
