19 August 19852 21P/Giacobini–Zinner Flyby 1Spacecraft failure
(Extended mission)
Extended mission, spacecraft ran out of fuel en route; flyby had been scheduled for 24 November 1998[8]
Deep Space 1 1 24 October 19981 107P/Wilson–Harrington[9] Flyby 1Spacecraft failure Spacecraft was unable to reach Wilson–Harrington due to ion engine operation being suspended while a problem with the probe's star tracker was investigated.[10] Delta II 7326
24 October 19982 19P/Borrelly Flyby 4Successful Extended mission
Stardust
(Discovery 4)
7 February 1999 81P/Wild Flyby
Sample return
4Successful Delta II 7426
7 February 1999 9P/Tempel Flyby 4Successful Extended mission, Stardust-NExT, to survey crater caused by Deep Impact
CONTOUR
(Discovery 6)
3 July 2002 2P/Encke Flyby 1Spacecraft failure Delta II 7425
3 July 2002 73P/Schwassmann–Wachmann Flyby 1Spacecraft failure
3 July 2002 6P/d'Arrest Flyby 1Spacecraft failure Flyby provisionally scheduled at time of spacecraft's failure
Rosetta 2 March 2004 67P/Churyumov–Gerasimenko Orbiter 6Operational Entered orbit around 67P at 09:06 UTC on 6 August 2014. Ariane 5G+
Philae 2 March 2004 67P/Churyumov–Gerasimenko Lander 6 Inactive Came to rest on the surface of 67P at 17:32 UTC on 12 November 2014. Communications ceased with the loss of battery power at 00:36 UTC on 15 November 2014 and the lander is currently hibernating. May be able to reactivate on solar power in August 2015 when the comet comes closer to the sun. Ariane 5G+
