How about 'dedicated close encounters' and 'distant encounters of opportunity'?

Earth flew through the tail of Comet Halley in 1910. And since our planet has often been called Spaceship Earth....

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 |

Five years ago on February 12, 2001, the NEAR-Shoemaker probe became
not only the first one to orbit a planetoid (Eros), it also landed on the big ol' rock: http://near.jhuapl.edu/ And to think it was a Valentine's Day gift, too. -------------------- "After having some business dealings with men, I am occasionally chagrined,

I cannot found better topic than this one so I apologize for reanimation of this old topic.
Here is my collage of all cometary nuclei imaged by spacecrafts and planetary radars at 25 m/pix. Now it's with C/2013 A1 Siding Spring. -------------------- |

NEA Scout has been approved to piggyback on SLS, along with 12(!) other cubesats, four for the Moon, the rest for deep space, and three others from international partners, yet to be announced. The target is 1991 VG, which might actually be an artificial object from the 60s or 70s... |

Day of decision is coming! "During ESA’s ministerial conference in Luzern, December 1-2, 2016, the decision will be made whether or not to fund the Asteroid Impact Mission (AIM), a collaborative effort with the international AIDA mission. To reinforce the importance of the AIM mission within the scientific and space communities, asteroid experts Patrick Michel, Alan Fitzsimmons and Debbie Lewis drafted a letter in support of AIM [...] published here for the public to sign."

"Insiders say [AIM] missed their target sum by perhaps a few tens of millions. “A cool project has been killed because of a lack of vision, even short term, and courage, and this is really sad,” says Patrick Michel, a planetary scientist at the French National Centre for Scientific Research in Nice, who leads AIM. ..."

Darn, so close! Hopefully the DART component will be approved in March. Even a clone of the Deep Impact mission is better than nothing....

Wörner said a few days ago (9 Dec) that he is trying to rescue the AIM mission, though how realistic that is, I have no idea.
QUOTE Woerner, on the lack of funding for the Asteroid Impact Mission: I don’t give up. I keep fighting for it because it is too important. QUOTE Woerner on AIM: ran into problems when Germany offered less than expected, then withdrew funding altogether. Still working to “rescue” it. https://twitter.com/jeff_foust/status/807274575658618880 https://twitter.com/jeff_foust/status/807278269011738624 -------------------- |

there was an article about AIM in this week's "the Space Review"
AIM misses the funding target, for now |
