Where is the New Horizons Spacecraft right now?
The app above shows you where the New Horizons Spacecraft is today, right this moment, in an interactive animation. It also shows the position of Pluto and also two Kuiper Belt Objects, 2014 MU69 which is New Horizon's next target and 2014 PN70 (which was a candidate target). New Horizons completed some manoeuvres in October/November 2015 in order to achieve a rendezvous with 2014 MU69 (an approximately 45km diameter object) around the 31st December 2018 or 1st January 2019 (the position of 2014 MU69 still needs refining). NASA Release. Article.
The rendezvous with 2014 MU69 will be an historic event although the fact that it will all be going on with the Sun sitting in between the earth and New Horizons probably means we may well have to wait quite a while - longer than we did with Pluto - for the first pictures.
You can wind the animation backwards in time to watch its launch and its flyby of Jupiter, and forwards to watch its encounter with Pluto and beyond. You can stop it at any time to see its position and the position of the planets during its flight. The 2D/3D button shows planets or New horizons on "3D" stalks to represent the distance above or below the plane of the ecliptic.
If your browser doesn't support flash then we provide a video which also allows you to see an animation of the New Horizons journey from Earth to Pluto and on.

New Horizons images
New Horizons discovers flowing ices in Pluto’s heart-shaped feature. In the northern region of Pluto’s Sputnik Planum (Sputnik Plain), swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth.

The left side of heart shaped region on Pluto appears to be a huge glacier made of nitrogen and other frozen gasses. It can be seen flowing around mountians and other features at its edge and even flows through breaches in the walls of ancient craters to fill or part fill the interiors. Scientist are suggesting that the polygonal shapes seen in the ice may possibly be due to a convection processes where warmer material is welling up from deep below.
Shown below is the southern edge of the glacier:
New Horizons detected a few surprises to do with Plutos atmosphere. Recent measurements (by watching stars as they passed behind pluto from earth or earth orbit telescopes) showed that the pressure of plutos atmosphere has been steadily increasing - against scientific understanding that thought as pluto got further from the sun its pressure should drop. Indeed the team were in a hurry to get New Horizons launched before the atmosphere dissappeared altogether. However the first result from New Horizons shows that the atmopheric pressure has dropped to approximately half the last measurement. Perhaps New Horizons got to pluto just as its atmosphere is collapsing as it goes into deep freeze or something else is happening. Full Story.
Also, as seen in the above image, New Horizons detected hazing in Plutos atmosphere at 52 miles high and 31 miles high. Again these layers were not expected and are not understood. The haze occurs when methane gas is broken down by sunlight and causes more complex molecules such as ethylene and acetylene to be created. These hydrocarbons then freeze and form tiny particles that slowly fall to the surface and are visible as a haze. Full Story.
New Horizons scientists use enhanced color images to detect differences in the composition and texture of Pluto’s surface. It can be clearly seen that the nitrogen glacier in the left of the heart shape differs from the material in the right. Credits: NASA/JHUAPL/SwRI. Click for full story.
Pluto's moon Nix (left), shown here in enhanced color as imaged by the New Horizons Ralph instrument, has a reddish spot that has attracted the interest of mission scientists. The data were obtained on the morning of July 14, 2015, and received on the ground on July 18. At the time the observations were taken New Horizons was about 102,000 miles (165,000 km) from Nix. The image shows features as small as approximately 2 miles (3 kilometers) across on Nix, which is estimated to be 26 miles (42 kilometers) long and 22 miles (36 kilometers) wide. Pluto's small, irregularly shaped moon Hydra (right) is revealed in this black and white image taken from New Horizons' LORRI instrument on July 14, 2015 from a distance of about 143,000 miles (231,000 kilometers). Features as small as 0.7 miles (1.2 kilometers) are visible on Hydra, which measures 34 miles (55 kilometers) in length. Image Credit: NASA-JHUAPL-SwRI
A newly discovered mountain range lies near the southwestern margin of Pluto’s Tombaugh Regio (Tombaugh Region), situated between bright, icy plains and dark, heavily-cratered terrain. This image was acquired by New Horizons’ Long Range Reconnaissance Imager (LORRI) on July 14, 2015 from a distance of 48,000 miles (77,000 kilometers) and received on Earth on July 20. Features as small as a half-mile (1 kilometer) across are visible. Click for full story. Image Credit: NASA-JHUAPL-SwRI
Animated Flyover of Pluto’s Icy Mountain and Plains
This simulated flyover of Pluto’s Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain) was created from New Horizons closest-approach images. Norgay Montes have been informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest. Sputnik Planum is informally named for Earth’s first artificial satellite. The images were acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as a half-mile (1 kilometer) across are visible. Credit: NASA/JHUAPL/SWRI
In the center left of Pluto’s vast heart-shaped feature – informally named “Tombaugh Regio” - lies a vast, craterless plain that appears to be no more than 100 million years old, and is possibly still being shaped by geologic processes. This frozen region is north of Pluto’s icy mountains and has been informally named Sputnik Planum (Sputnik Plain), after Earth’s first artificial satellite. The surface appears to be divided into irregularly-shaped segments that are ringed by narrow troughs. Features that appear to be groups of mounds and fields of small pits are also visible. This image was acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as one-half mile (1 kilometer) across are visible. The blocky appearance of some features is due to compression of the image. Click for full story. Image Credit: NASA-JHUAPL-SwRI
New close-up images of a region near Pluto’s equator reveal a giant surprise: a range of youthful mountains rising as high as 11,000 feet (3,500 meters) above the surface of the icy body. The close-up image was taken about 1.5 hours before New Horizons closest approach to Pluto, when the craft was 478,000 miles (770,000 kilometers) from the surface of the planet. The image easily resolves structures smaller than a mile across. Click for full story. Image Credit: NASA-JHUAPL-SwRI
Remarkable new details of Pluto’s largest moon Charon are revealed in this image from New Horizons’ Long Range Reconnaissance Imager (LORRI), taken late on July 13, 2015 from a distance of 289,000 miles (466,000 kilometers). A swath of cliffs and troughs stretches about 600 miles (1,000 kilometers) from left to right, suggesting widespread fracturing of Charon’s crust, likely a result of internal processes. At upper right, along the moon’s curving edge, is a canyon estimated to be 4 to 6 miles (7 to 9 kilometers) deep. Click for full story. Image Credit: NASA-JHUAPL-SwRI
Since its discovery in 2005, Pluto's moon Hydra has been known only as a fuzzy dot of uncertain shape, size, and reflectivity. Imaging obtained during New Horizons' historic transit of the Pluto-Charon system and transmitted to Earth has definitively resolved these fundamental properties of Pluto's outermost moon. Long Range Reconnaissance Imager (LORRI) observations revealed an irregularly shaped body characterized by significant brightness variations over the surface. With a resolution of 2 miles (3 kilometers) per pixel, the LORRI image shows the tiny potato-shaped moon measures 27 miles (43 kilometers) by 20 miles (33 kilometers). Image Credit: NASA-JHUAPL-SwRI
Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard NASA’s New Horizons spacecraft, taken on July 13, 2015 when the spacecraft was 476,000 miles (768,000 kilometers) from the surface. Click for full story. Credits: NASA/APL/SwRI
On July 11, 2015, New Horizons captured a world that was growing more fascinating by the day. For the first time on Pluto, this view revealed linear features that may be cliffs, as well as a circular feature that could be an impact crater. Rotating into view is the bright heart-shaped feature that was seen in more detail during New Horizons’ closest approach on July 14. Click for full story. Credits: NASA/JHUAPL/SWRI
This is New Horizons' last look at Pluto's Charon-facing hemisphere and reveals intriguing geologic details. This image, taken early the morning of July 11, 2015, shows newly-resolved linear features above the equatorial region that intersect, suggestive of polygonal shapes. This image was captured when the spacecraft was 2.5 million miles (4 million kilometers) from Pluto. Image credit: NASA/JHUAPL/SWRI

New Horizons Flight Path
New Horizons was launched on 19th January 2006 directly into an Earth-and-Solar-escape trajectory. It had the highest launch velocity of any man made object at over 16km/s relative to earth.
Asteroid 132524 APL
In June of 2006, it was realised that the spacecraft was going to pass relatively close (100,000 km) to a small asteroid called 132524 APL. This asteroid was imaged by the space probe (as a small dot) and found, amongst many other new observations, to be about 2.5km across.
The probe began studying Jupiter and its moons in detail from January until June of 2007. Its closest approach at the end of February was 2.3 million km from the planet. The fly-by increased New Horizons velocity by 4 km/s allowing it to reduce its journey to Pluto by 3 years.
During the fly-by New Horizons was able to study Jupiter's atmosphere and faint ring system in detail including imaging "the little red spot" in more detail than ever before.
New Horizons flight path did not take it near any of the major Jovian moons, but its sensors being designed to image small objects in low light levels were able to obtain impressive images of volcanic eruptions on Io amongst other interesting observations. Below is a New Horizons animation showing eruptions on IO.
Due to its very high launch speed, New Horizons has been able to take a very direct route towards Pluto without using a large number of gravitational sling shots to achieve a suitable velocity. The schedule of its mission is listed below:
|Earth, Launch||19 January 2006|
|132524 APL, Flyby||13 June 2006|
|Jupiter, Flyby||28 Feb 2007|
|Pluto, Flyby||14 June 2015|
|Observe other KBOs||2016-2020|
|End of Mission||2026|
