Extended mission, spacecraft ran out of fuel en route; flyby had been scheduled for 24 November 1998[8] | ||||
Deep Space 1 | 24 October 1998 | NASA United States |
107P/Wilson–Harrington[9] | Flyby | Spacecraft 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 |

3 July 2002 | NASA United States |
2P/Encke | Flyby | Spacecraft failure | Delta II 7425 | |
73P/Schwassmann–Wachmann | Flyby | Spacecraft failure | |||||
6P/d'Arrest | Flyby | Spacecraft failure | Flyby provisionally scheduled at time of spacecraft's failure | ||||
Rosetta | 2 March 2004 | ESA | 67P/Churyumov–Gerasimenko | Orbiter | Successful | Entered orbit around 67P at 09:06 UTC on 6 August 2014. On 30 September 2016 mission ended in an attempt to slow land on the comet's surface near a 130 m (425 ft) wide pit called Deir el-Medina. | Ariane 5G+ |

67P/Churyumov–Gerasimenko | Lander | Successful | Carried by Rosetta. 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 began hibernating. Reactivated on solar power and briefly established contact with ground control again at 20:28 UTC on 13 June 2015, and sporadically until 9 July 2015 when the last communication was received.[11][12] | Ariane 5G+ |
