One of the strangest landforms spotted by NASA’s New Horizons spacecraft when it flew past Pluto was the “bladed” terrain formally named Tartarus Dorsa. The blades reach hundreds of feet high and are typically spaced a few miles apart. No geology degree is necessary to see why the terrain is so interesting — just grab your red and green 3-D spectacles.
Pluto’s day is 6.4 Earth days long. The dwarf planet’s largest moon, Charon, also rotates once every 6.4 days as the two worlds are tidally locked to each another. This sequence of images from the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera on NASA’s New Horizons spacecraft shows us full rotations of the two bodies.
In September, the New Horizons team released a stunning but incomplete image of Pluto’s crescent. Thanks to updated processing work by the science team, New Horizons is releasing the entire, breathtaking image of Pluto. The team also released images showing extended mapping of the dwarf planet’s “heart” feature and young craters on Pluto’s largest moon, Charon.
The New Horizons team described a wide range of findings about the Pluto system in its first research paper published today — just three months after NASA’s historic first exploration of the dwarf planet. New Horizons has revealed a degree of diversity and complexity on Pluto and its moons that few expected in the frigid outer reaches of the solar system.
NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect.
A new close-up image of Pluto from New Horizons reveals a vast, craterless plain that appears to be no more than 100 million years old. This frozen region is north of Pluto’s icy mountains, in the centre-left of the heart feature, informally named “Tombaugh Regio” (Tombaugh Region) after Clyde Tombaugh, who discovered Pluto in 1930.
