ASTEROID BELT OUTER SOLAR SYTEM

SATURN SOJOURN

Few missions have visited

the planet, but Cassini

arrived in 2004 and

explored for 13 years; data

are still being processed.

HALLEY’S COMET

On an eccentric orbit that

travels past Neptune, Halley

returns to the inner solar system

every 76 years. Various craft

studied its last visit, in 1986.

TURBULENT JUPITER

The first missions to the planet

revealed a ball of violent,

swirling gases. Some of Jupiter’s

moons have been studied for

the potential to harbor life.

THE MOON AND ITS PROSPECTS

Space companies are determining

whether there’s money to be made

on Earth’s nearest neighbor through

projects like mining, commercial

travel, and colonization.

ASTEROID ENCOUNTERS

Filled with protoplanetary bodies,

the asteroid belt holds clues to how

our solar system and planets formed.

Probes have visited and collected

samples from asteroids.

KUIPER BELT

Reaching the most distant bodies

in our solar system, the New

Horizons spacecraft was the first

to visit Pluto; it then flew on to

explore Ultima Thule.

LIVING AND WORKING WHILE ORBITING EARTH

International crews have continued to conduct research on Earth-orbiting stations, while

for 30 years NASA’s reusable space shuttles carried crew and cargo on a variety of missions.
