Fantastic new images of Ceres continue to spill out of the Dawn mission, and armchair scientists all over the world are zooming into them, exploring them, and trying to solve the puzzles that they contain.
The nature of the origin of life is a topic that has engaged people since ancient times. The samples to be collected by OSIRIS-REx, returned to the Earth in 2023 and archived for decades beyond that, may indeed hide the secrets to the origin of life.

The OSIRIS-REx team has been busy assembling and testing the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) and the Sample Return Capsule (SRC).
New Horizons took its first color photo of Pluto and Charon, while Dawn obtained a 20-frame animation looking down on the north pole of a crescent Ceres.
PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.
From Italy, Bruce Betts gives background and information at the start of the Planetary Defense Conference, which addresses the asteroid threat. Bruce summarizes steps to prevent asteroid impact.

Thanks to a new focal reducer and re-aluminized mirror from a Shoemaker NEO grant, a 0.81-meter telescope in Italy is performing astrometric follow-up observations and physical studies of asteroids.
NASA has decided to pluck a small boulder off a large asteroid, instead of bagging an entire asteroid outright, the agency announced Wednesday.
Three talks on Tuesday at the Lunar and Planetary Science Conference concerned the first results from Dawn at Ceres. Chris Russell showed a map of "quads" with provisional names on Ceres, Andreas Nathues showed that Ceres' bright spot might be an area of plume-like activity, and Francesca Zambon showed color and temperature variations across the dwarf planet.
A huge amount of effort goes into deciding where to try to collect a sample on Bennu. There are roughly nine months to survey, map and model the asteroid to help make this decision.
Having found a color photo of the comet, I finally added Churyumov-Gerasimenko to my scale comparison of comets and asteroids visited by spacecraft.
Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
