Plot thickens as New Horizons moves within year of next flyby

6 January 2018 Stephen Clark

The final days before NASA’s New Horizons probe barrels in on its next destination on Jan. 1, 2019, should prove eventful, with scientists trying to sort out whether a distant mini-world detected by the Hubble Space Telescope more than three years ago may actually be a swarm of icy objects.

Scientists firm up flyby plan for New Horizons’ next destination

Now more than two years outbound from its historic encounter with Pluto, NASA’s New Horizons spacecraft is on target for a fleeting flyby less than 2,200 miles from 2014 MU69, an icy, city-sized world set to become the most distant object ever visited, just after midnight Jan. 1, 2019. Scientists now say the probe may be able to pursue another destination some time in the 2020s.

New Horizons’ next target might be a binary pair

8 August 2017 Stephen Clark

Ground observations of the New Horizons spacecraft’s next target last month revealed the distant object, lurking in the outer Solar System more than four billion miles from Earth, might have an unconventional elongated shape, or even consist of two icy bodies orbiting one another in an age-old cosmic dance.

Pluto ‘paints’ its largest moon red

In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our Solar System, and they couldn’t wait to get the story behind it.

Pluto’s haze in bands of blue

This processed image is the highest-resolution colour look yet at the haze layers in Pluto’s atmosphere. Shown in approximate true colour, the picture was constructed from a mosaic of four panchromatic images from the Long Range Reconnaissance Imager (LORRI) splashed with Ralph/Multispectral Visible Imaging Camera (MVIC) four-colour filter data, all acquired by NASA’s New Horizons spacecraft on 14 July 2015.

No. 1 New Horizons at Pluto

3 January 2016 Keith Cooper

The long-awaited fly-by of Pluto by the New Horizons spacecraft, on 14 July 2015, was an event 85 years in the making, following Pluto’s discovery by Clyde Tombaugh in 1930. Since then, Pluto has gone from planet to dwarf planet, but despite protestations from the New Horizons team, its reclassification never really changed the mission or the importance of what it would find at Pluto.

Secrets behind Pluto’s pastels far from being answered

Geologists said Thursday they are bewildered by images from NASA’s New Horizons spacecraft baring unseen landscapes on Pluto with unexpected “snakeskin” textures, colourful chasms routing through ancient landforms, and vivid new views of apparent glacial flows.
