PLUTO HEART

Formally known as **Sputnik Planitia**, this nitrogen-ice glacier proved Pluto is geologically active, featuring flowing ices and mountain ranges made of water-ice.

PLUTO DATA
Feature: Geologic Activity

ARROKOTH FLYBY

In 2019, New Horizons visited **Arrokoth**, the farthest object ever explored. Its unique "double-lobed" shape provided key insights into planetary formation.

KBO DATA
Distance: 4+ Billion Miles

LORRI CAMERA

The Long Range Reconnaissance Imager is the craft's high-resolution digital eye. It captured the iconic portraits of Pluto’s atmosphere and diverse moons.

New Horizons Mission FAQs

Tracing NASA's historic journey to Pluto, Charon, and the deep Kuiper Belt

What was the primary objective of the New Horizons mission? +

New Horizons was designed to perform the first reconnaissance of Pluto, its moons, and subsequent targets deeper within the mysterious Kuiper Belt.

When did the spacecraft launch and reach Pluto? +

It launched from Cape Canaveral on January 19, 2006, and completed its historic close flyby of Pluto on July 14, 2015, after a 9.5-year journey.

What major geological features were discovered on Pluto? +

The probe revealed a complex world featuring flowing nitrogen ice glaciers, towering water-ice mountains, and an iconic heart-shaped basin named Sputnik Planitia.

What deep-space target did New Horizons visit after Pluto? +

On January 1, 2019, the spacecraft successfully flew past the Kuiper Belt object **Arrokoth**, making it the most distant world ever explored up close.

How fast was New Horizons traveling upon launch? +

It achieved the highest launch velocity ever recorded for a human-made object relative to Earth, traveling at roughly 36,400 miles per hour.

Did the spacecraft get a gravity assist along the way? +

Yes, it performed a high-speed gravity-assist flyby of Jupiter in February 2007, which shortened its travel time to Pluto by three years.

What powers the New Horizons spacecraft so far from the Sun? +

Because solar panels are ineffective in the outer solar system, it relies on a Radioisotope Thermoelectric Generator (RTG) running on decaying plutonium-238.

What scientific instruments are on board the probe? +

It carries seven science instruments, including high-resolution telescopic cameras (LORRI and Ralph), ultraviolet and infrared spectrometers, and plasma sensors.

What discoveries were made about Pluto's moons? +

The mission mapped Pluto's largest moon Charon (revealing a red polar cap and tectonic chasms) and found that smaller moons like Nix and Hydra spin chaotically.

Is New Horizons still active today? +

Yes, it continues to speed outward through the Kuiper Belt, gathering unique heliospheric data and distant astronomical observations.
