Looks like DART is still going ahead (preliminary design phase now): https://www.nasa.gov/feature/nasa-s-first-a...xt-design-phase
I've seen no news on AIM though; no getting our hopes up? |

last I heard, ESA was studying an AIMlight mission, costing no more than 150 million euros

I've seen no news on AIM though; no getting our hopes up? "La sonde AIM ne pourra pas être lancée en 2020 comme prévu, a reconnu l'ESA qui réfléchit à envoyer une caméra qui volerait sur DART et se détacherait peu avant l'impact." It seems AIM is more or less dead, no launch in 2020. Instead, ESA is considering launching a detachable camera on DART. |

A very detailed summary, but note a slight error in the size of Didymos: 780 metres, not kilometres!

New animation of the current mission plan for Hera: https://www.youtube.com/watch?v=uIKpSKZ5HAs
Overall similar to AIM except obviously arrival is along after the DART impact. Pity the original plan for dual operations fell through! |

More on the DART mission is on this NASA page - launch should be in about 2 years: https://www.nasa.gov/planetarydefense/dart,
and on this APL page with an upcoming April 2019 planning meeting: http://dart.jhuapl.edu/ -------------------- Steve [ my home page and planetary maps page ]

Comet Interceptor is a mission proposal on a shortlist of six for ESA's F-class mission call. The mission would target a dynamically new comet from the Oort Cloud, or an interstellar object. ESA is expected to select the F-class mission in July 2019. Launch would be with ESA's Ariel exoplanet observatory in 2028.
Comet Interceptor would wait at Sun-Earth L2 until a suitable target is found inbound by survey observatories such as LSST. The primary spacecraft would deploy subspacecraft for the comet encounter, providing multi-point in situ measurements of the environment near the comet, as well as different remote sensing viewpoints of the nucleus and coma. The mission's website is here, where the team are inviting registration of support for the proposal: http://www.cometinterceptor.space/ The Twitter handle is @cometintercept |

some amazing high-resolution images of (7) Iris taken by the VLT in this paper:

Hera has been chosen at the most recent ESA budget meeting. There is also a call out for amateur astronomer to start characterizing possible flyby candidates:
