The first manmade object to visit the planet Saturn was on a trajectory to leave our solar system. In 4 million years, it will reach stars from the Aquila constellation.

This probe mission was the first to explore Mercury. Using many instruments, it revealed the planet's thin atmosphere. magnetic field, ond iron core.

Since 1977, this probe has been sending data back to Earth. It has now entered the farthest corners of our solar system, reaching Uranus and Neptune.

Galileo Galilei first observed Jupiter and its moons with his telescope in 1610. He could not have imagined that several centuries later a probe mission would visit them.

Overcoming a legacy of fire, this Soviet program became the first to land a probe on Venus and the first to send images of another planet's surface to Earth.

To learn more about the composition of Jupiter's atmosphere, this 2011 NASA probe observed every longitude of the planet from its polar orbit.

The MESSENGER probe orbited Mercury for 4 years. In that time, it completed 4000 orbits and sent hundreds of photographs of the planet's surface back to Earth.

The Cassini probe spent 7 years traveling to Saturn and its moons. Its discoveries significantly changed our knowledge of Saturn and its atmosphere.

One of the most powerful rockets in existence, this partially reusable spacecraft from SpaceX is capable of carrying 63 tons of cargo into low orbit.

This Norse-inspired ESA mission would send two probes, Freyr and Freyja, to study Uranus and Neptune, the least explored planets in our solar system.

Many projects end before they even start. Without financial support from governments or private organizations, many successful projects would not exist.

Arthur C. Clarke believed that Europa had the potential to sustain human life. The Europa Clipper probe honors Clarke's ambition by studying the moon's surface.

Since 2021, this car-sized rover has been traveling the surface of Mars. Time will tell whether the rock and soil samples it collects will reveal signs of life.

Could life survive in the inhospitable atmosphere on Mars? By recreating the environment of Mars in a lab on Earth, scientists hope to find an answer.

Despite returning valuable data, the Galileo mission's atmospheric probe only lasted 58 minutes against the 28,000-degree heat it reached in Jupiter's atmosphere.

Taking advantage of Titan's low gravity, the planned Dragonfly rotorcraft will look for any signs of life hidden under the moon's thick atmosphere.

By collecting samples from the ancient Bennu asteroid, the OSIRIS-REx probe may help us understand more about the origins of life in our solar system.

Using a mini-lander, this probe collected 1500 dust grains from the asteroid Itokawa. That's a pretty impressive interstellar vacuum cleaner.

A maneuver made famous by its appearance in the novel 2001: A Space Odyssey, the gravity slingshot is utilized to save fuel across space missions.

Thanks to the power of the Sun's gravitational pull accelerating the probe, the Mariner 10 was able to complete three deceleration flybys past Mercury in a single voyage.

The first successful mission to another planet in history was the Mariner 2's Venus flyby in 1962. It took the probe 110 days to reach Venus after its launch.

The exploration of Mars's surface was preceded by several flyby missions. The first was the Mariner 4, which flew by the planet in 1965.

The gravitational slingshot is used by many probes that conduct Jupiter flybys. Pioneer 10 was the first mission to send photos of the planet to Earth.

Humanity first visited Saturn during the Pioneer 11 flyby mission, which flew through the rings of Saturn in 1979.

The slow but steady pressure of sunlight on these enormous solar sails will allow probes equipped with them to travel great distances without any fuel involved.

The stones in the asteroid belt range from a few millimeters to thousands of kilometers in size. Probes require precise navigation in order to safely pass through.

Seeing beyond the smog and light pollution of Earth's atmosphere, the striking images that Hubble transmits have challenged the limits of our scientific knowledge.

The Kepler telescope discovered thousands of exoplanets orbiting distant stars in our galaxy, including planets where life could exist.

The largest and most powerful telescope ever created, this complex instrument has allowed us to peer into the deepest corners of the universe.

Using a combination of four telescopes, the entire electromagnetic spectrum over the world studies what this project reveals.

NASA's Space Launch System is capable of getting humanity back to the Moon and beyond. This modular system can carry a range of equipment in a single rocket.

Extreme heat and radiation make Mercury difficult to explore. Progress was made in 2008 when the MESSENGER probe mapped the planet's surface.

Venus's acidic atmosphere and extreme pressure make surface exploration very difficult. The probes that have landed on the planet survived for only a few minutes.

The relative proximity and thin atmosphere of Mars make it an ideal candidate for exploration by ground probes. Several of them roam its surface today.

Jupiter's enormous size has allowed humans to explore the planet remotely since the Middle Ages. In present times, the Juno probe orbits the planet and its moons.

Over 95% of Saturn's volume is hydrogen. This makes its average density less than that of water. Despite this, 145 moons have been confirmed to orbit the planet.

This red dwarf is the closest star to our Sun, only 4 light years away. It's possible that one of the planets orbiting this star may contain liquid water.

A planet slightly larger than Earth apparently orbits this famous red dwarf. The star is located in the Ophiuchus Constellation, 6 light years from Earth.

Located in the constellation Virgo, 61 Virginis shares several properties with our own Sun. The star is orbited by two planets, one of which may support life.

587 light years away from Earth, Kepler 22 is orbited by the first discovered exoplanet to exist in a habitable zone. This means that it may contain life.

This binary star is the brightest in our night sky. Its luminosity makes the star ideal for observing any exoplanets that orbit it.

Located in the constellation Canis Minor, this star is 12 light years away from Earth. Although no exoplanets have been confirmed in Procyon's orbit, research continues.

This star, located in the Pictor constellation, is orbited by a very dense cloud of dust. It is possible that new planets could form within this cloud.

Vega is a young, rapidly rotating star that fluctuates in brightness. If there is a planet orbiting it, any life on it would exist in a completely different form from life on Earth.

Historically, SETI relied on the intermittent use of existing equipment. Private funding allowed the institute to construct this dedicated array for 24/7 observation.

By watching the coldest parts of the universe, this telescope array is designed to observe the birth of new stars. Its findings could be the key to discovering life.

If a single antenna were to match the power of this 27-telescope array in New Mexico, it would have to be 36 kilometers in diameter.

The Breakthrough Starshot project may allow us to finally reach Alpha Centauri. Doing so would take a fleet of light-equipped probes 20-30 years.

Using the NEAR coronagraph, this Breakthrough initiative hopes to find rocky planets around stars up to 20 light years away from Earth.

From a central hub, this array will extend out to a distance of 2,300 kilometers. Its physical expanse is matched by the planned scope of its observations.

Even after decades of operation, this radio telescope is not ready to retire. Astronomers still use the Lovell to track the movements of interstellar objects.

Shielded from electromagnetic waves by the Australian hills, the Parkes Observatory has received radio signals from distant stars and from NASA missions.
