Just one week left! This page will soon sign off, but don’t worry! New Horizons is still cruising through the cosmos. Follow NASA Solar System Exploration for all the latest.

Learn more about the mission:

New Horizons was the first spacecraft to explore Pluto and its five moons up close and, later, made the first close exploration of a Kuiper Belt Object.

Findings from NASA’s New Horizons mission show persistent dust impacts well beyond Pluto. This suggests the Kuiper Belt may be larger than expected or that something else is at play in the outer solar system. https://www.nasa.gov/missions/new-horizons/nasas-new-horizons-detects-dusty-hints-of-extended-kuiper-belt/

Preparations are in full swing for a major upgrade to New Horizons’ onboard fault detection and correction software. This update will ensure the spacecraft’s operations as it ventures even farther from the Sun and operates on lower power. The software will be uploaded in late July.

Just roused from hibernation, New Horizons starts six months of active operations that will include long-distance looks at Kuiper Belt objects and close-up data gathering on the dust and radiation environment in this remote part of our Sun’s heliosphere. https://science.nasa.gov/mission/new-horizons/

NASA’s New Horizons is still exploring! The mission team is using the Subaru Telescope in Hawaii to search for a new Kuiper Belt Object (KBO) flyby target—continuing its groundbreaking journey through the outer solar system. 🌌🔭

The next observing run is scheduled for June 2025 as the team scans the vast reaches of space for a distant world to explore. More: https://science.nasa.gov/mission/new-horizons/

In February 2007, NASA’s New Horizons made history as the fastest spacecraft to reach Jupiter—arriving in just 13 months! 🚀 Using the giant planet’s gravity, it picked up even more speed and captured breathtaking images of Jupiter and its moons. This flyby was a crucial milestone on the path to Pluto and beyond.

From January 15-17, the New Horizons science team convened at JHU Applied Physics Laboratory (APL) in Maryland, diving into the latest scientific results and mapping out plans in planetary and heliophysics research. 🌍🌞🚀

Discussions ranged from new discoveries at the edge of our solar system to plans for the mission’s extended operations. Learn more about New Horizons as the mission continues its journey into the outer reaches of space: science.nasa.gov/mission/new-horizons

How dark is deep space? 🌌

Astronomers may have finally answered this cosmic question thanks to New Horizons, which captured the faint glow of the universe from over 5.4 billion miles away. The findings reveal that the Cosmic Optical Background (COB) is entirely explained by light from galaxies—no exotic or unknown sources required.

This breakthrough, which will be presented at by Space Telescope Science Institute's Marc Postman, underscores the power of New Horizons’ distant location and innovative capabilities.
