New Horizons Spots Its Next Flyby Target: Kuiper Belt Object 2014 MU69

The figure on the left is a composite image produced by adding 48 different exposures from News Horizons’ Long Range Reconnaissance Imager, each with an exposure time of 29.967 seconds, taken on August 16, 2018. The predicted position of 2014 MU69 is at the center of the yellow box, and is indicated by the yellow crosshairs, just above and left of a nearby star that is approximately 17 times brighter than 2014 MU69. At right is a magnified view of the region in the yellow box, after subtraction of a background star field ‘template’ taken by LORRI in September 2017 before it could detect the object itself. 2014 MU69 is clearly detected in this star-subtracted image and is very close to where scientists predicted, indicating to the team that New Horizons is being targeted in the right direction. The many artifacts in the star-subtracted image are caused either by small mis-registrations between the new LORRI images and the template, or by intrinsic brightness variations of the stars. At the time of these observations, 2014 MU69 was 107 million miles (172 million km) from the New Horizons spacecraft and 4 billion miles (6.5 billion km) from the Sun.

NASA’s New Horizons spacecraft has made its first detection of its next target, the Kuiper Belt object 2014 MU69, more than four months ahead of its 2019 close encounter.

It is estimated to have a diameter of 30 miles (48 km) — that’s more than...

On Earth, the Northern and Southern lights occur when the solar wind (electrically charged particles from the Sun) follow our planet’s geomagnetic field lines to the poles and collide with the upper atmosphere. Mars lacks a global magnetic field, so instead the solar wind piles up in front of Mars in a bow shock, which blocks charged particles from reaching the bulk of the atmosphere. However, in a process first observed by NASA’s MAVEN spacecraft, some solar wind protons can slip past the bow shock by first bonding with electrons from the Martian upper atmosphere to form hydrogen atoms. Because these hydrogen atoms are electrically neutral, they can pass through the bow shock and go on to create an ultraviolet proton aurora on the dayside of Mars.

This mosaic of Cerealia Facula is based on images obtained by NASA’s Dawn spacecraft in its second extended mission, from an altitude as low as about 21 miles (34 km). The contrast in resolution obtained by the two phases is visible here, reflected by a few gaps in the high-resolution coverage. This image is superposed to a similar scene acquired in the low-altitude mapping orbit of the mission from an altitude of about 240 miles (385 km). The increased resolution afforded by the low altitude is revealing intimate details about the relationships between bright and dark materials across the facula, which will help resolve the mystery of its origin. Cerealia Facula is located at about 19.7 degrees north latitude and 239.6 degrees east longitude. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA / PSI.

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.
