Trying to give an overview of missions to Asteroids & comets …
Giotto ( 2 July 1985 to comet HALLEY in 1986 and to comet Grigg-Skjellerup in 1992 ) NEAR Shoemaeker ( 17 February 1996 to asteroid 433 Eros in February 2001 ) Deep Space 1 ( 15 October 1998 to comet BORELLY in September 2001 ) StarDust ( 07 February 1999 to comet WILD-2 in January 2004 ) Contour ( July 2002 to comet ENCKE … mission failure ) Deep Impact ( 12 January 2005 to comet TEMPLE-1 in July 2005 ) Which missions did I forget ? … … … |

Flyby: September 11, 1985 Vega 1 and Vega 2, Comet 1P/Halley flybys (Soviet Academy of Sciences) Launch: December 15 and 21, 1984. Flyby: March 6 and 9, 1986 Sakigake, Comet 1P/Halley flyby (Institute of Space and Aeronautical Science (ISAS)) Launch: January 8,1985. Flyby: March 11, 1986 Suisei, Comet 1P/Halley flyby (Institute of Space and Aeronautical Science (ISAS)) Launch: March 18, 1985. Flyby: March 8, 1986 Giotto, Comets 1P/Halley and 26P/Grigg-Skjellerup flyby (ESA) Launch: July 2, 1985. Halley flyby: March 13, 1986. Grigg-Skjellerup flyby: July 10, 1992 Galileo, Flyby of asteroids 951 Gaspra and 243 Ida; Jupiter orbiter (NASA) Launch: October 18, 1989. Gaspra flyby: October 29, 1991. Ida/Dactyl flyby: August 28, 1993. Witnessed Shoemaker-Levy crash: July 1994 Near Earth Asteroid Rendezvous (NEAR), Asteroid 433 Eros orbiter (eventually used as a lander!) (NASA) Launch: February 17, 1996. Eros arrival: February 14, 2000. Eros landing: February 12, 2001 Deep Space 1, Flybys of asteroid 9969 Braille and comet 19P/Borrelly (NASA) Launch: October 24, 1998. Braille flyby: July 28, 1999. Borrelly flyby: September 22, 2001 Stardust, Flyby and coma sample return from comet P/Wild 2 Launch: February 7, 1999. Wild 2 flyby: January 2, 2004. Sample return: January 15, 2006 Comet Nucleus Tour (CONTOUR), Failed multi-comet flyby (NASA) Launch: July 3, 2002. Lost August 15, 2002 Deep Impact, Flyby and impact into comet 9P/Tempel 1 Launch: January 12, 2005. Tempel 1 impact and flyby: July 4, 2005 Hayabusa (MUSES-C), Orbiter and sample return from asteroid Itokawa (1998 SF36) (ISAS) Launch: May 9, 2003. Itokawa arrival: September 2005 Rosetta, Comet 67P/Churyumov-Gerasimenko orbiter and lander (ESA) Launch: March 2, 2004. Churyumov-Gerasimenko arrival: 2014 Dawn, Planned 4 Vesta and 1 Ceres orbiter (NASA) Launch: planned for May 27, 2006 (suspended indefinitely) Looks like my list is missing NEAR at Mathilde and Cassini at Masursky (and I've got to update the Hayabusa info on the page). I'll wait for this thread to develop a bit and then get to work Do you all think that the Ulysses comet tail encounters "count"? --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Soviet scientists considered an option to send the VEGA probes to other
celestial objects after Venus and Halley in 1986. One prime target was the near-Earth planetoid 2101 Adonis, which VEGA 2 could pass at a distance of six million kilometers (3.6 million miles). Sadly, the Soviets had to back out on the opportunity to become the first nation to fly a spacecraft past a planetoid when it was discovered that there was not enough maneuvering fuel in the probe to reach Adonis as planned. VEGA 1 and 2 were quietly shut down in early 1987. Information from: Robertson, Donald F., "Venus - A Prime Soviet Objective" (Parts 1/2), SPACEFLIGHT, Volume 34, Numbers 5/6, British Interplanetary Society (BIS), London, England, May/June 1992 Considering how relatively poor the images of Halley were from the VEGAs, I have to wonder how much could have been seen and learned if they did do that flyby of Adonis? Is there anything of interest about Adonis that might warrant a future mission to that worldlet? Besides its being an NEO? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
