Live coverage: New Horizons returns first close-up image

This image from NASA’s New Horizons spacecraft focuses on a section of the informally named Serenity Chasma, part of a vast equatorial belt of chasms on Pluto’s largest moon, Charon. Scientists believe that Charon’s subsurface water-ice layer may have been partially liquid in its early history, and has since refrozen, expanded and pushed the surface outward, producing the massive chasms we see today.

The icy plains of Pluto resolved by NASA’s New Horizons spacecraft stretch as wide as Texas, enveloping mountain ranges and bizarre hilly outcrops in a mosaic revealing one lobe of the distant world’s heart-shaped reservoir of exotic frozen carbon monoxide, nitrogen and methane.

Five years after missing a shot to enter orbit at Venus, Japan’s Akatsuki spacecraft completed a critical rocket burn early Monday in a bid to salvage the research mission and become the only space probe operating around Earth’s nearest planetary neighbor.
