Live coverage: New Horizons returns first close-up image

Two days before its final plunge into Saturn, the Cassini spacecraft turned its camera toward the ringed world to take a series of images for a colour mosaic, capturing a last evocative close-up until a new mission reaches the planet.

At the Palomar Observatory near San Diego, astronomers are busy tinkering with a high-tech instrument that could discover a variety of objects both far from Earth and closer to home. The Caltech HIgh-speed Multi-colour camERA (CHIMERA) system is looking for objects in the Kuiper Belt, the band of icy bodies beyond the orbit of Neptune that includes Pluto.

A concept called Comet Hitchhiker, developed at NASA’s Jet Propulsion Laboratory, puts forth a new way to get into orbit and land on comets and asteroids, using the kinetic energy — the energy of motion — of these small bodies. Masahiro Ono, the principal investigator based at JPL, had Douglas Adams’ “Hitchhiker’s Guide to the Galaxy” in mind when dreaming up the idea.
