Beginning of the Mission

NASA’s Jet Propulsion Laboratory was activated in the 1950s to join the space race – designing and operating robotic spacecraft and orbital and astronomy missions.

JPL was a pioneer of interplanetary exploration – they were tasked with creating the Mariner probes, launched from Atlas-Agena rockets, later Atlas-Centaur.

Mariner made history with their adventuring – the first planetary flyby, orbiter, and even a gravity assist maneuver.

Each Mariner was based around a hexagonal framework – packed with electronics and parts as varied as antennae and cameras for power and propulsion sources.

Ranger and Surveyor missions bode well for Apollo, but it was Mariner who truly charmed us all.

Timeline of the Mariner Missions

Mariner 1

Mariner 1 was an incredible mission. It had the potential to change what we thought we knew about Venus and answer questions that had remained unanswered for decades. But sadly, it wasn’t meant to be.

Just hours before the rocket’s launch, a fuse blew in its range safety circuit, and the mission had to be aborted. Then, when Mariner 2 was sent toward Venus, it immediately went off course and threatened inhabited areas should it crash.

Luckily JPL was able to prevent any more damage by ordering Mariner 2 to self-destruct rather than falling from the sky. This was a disaster but also a lesson learned–and one that made space exploration even safer in the years that followed.

Mariner 2

Exploration isn’t for the faint-hearted. It takes more than want and imagination – it takes careful planning, agility, and dedication. Mariner 2 was the perfect example of this spirit of discovery.

Despite experiencing technical issues, a mere month later, it proved that with better modifications and persistent hard work, we could achieve greatness. This spacecraft became the first in history to successfully reach another celestial body, reaching Venus after 110 days in space.

The mission concluded when the transmission was lost on January 2nd, 1963. But despite that, Mariner 2 continues its orbit around the mighty Sun to this day – a reminder of humanity’s never-ending curiosity and our drive to explore the unknown frontiers of space.

Mariner 3

NASA wanted to explore the mysterious surface of Mars, so with Mariner 3, they set out. It was fitted with four solar panels, a TV camera, and other instruments.

So it needed a rocket with greater firepower – the mighty Atlas-Agenda was launched, but sadly, due to a technical malfunction, the solar panels failed, and all power soon drained after 8 hours.

But this didn’t deter their dreams – in fact. They kept their spirits up and, despite the failure, still believed that it could be done!

They applied new technologies and tried again and were eventually successful in bravely landing on Mars with Mariner 4 – an even bigger and more advanced mission!

Mariner 4

Mariner 4 was a total game-changer. It worked hard to make history as the first spacecraft to get up close and personal with Mars. And it delivered, sending back 22 invaluable images that captured about 1% of the planet’s surface.

But even legends have their limits – 38 micrometeoroid hits weakened Mariner 4’s system and eventually meant that all contact was lost in December 1967, as it ran out of energy.

Still, it provided us with an incredible feat – something that no other mission had done before. It showed us just what could be achieved with courage and ambition, and set the benchmark for exploring the red planet, inspiring missions like Viking in the ’70s.

Mariner 4 opened up a world of possibilities: it brought distant Mars up close. And although its journey came to a bittersweet end, we’ll always carry this pioneer in our hearts.

Mariner 5

Mariner 5 was a backup but had an exciting mission of its own – a Venus flyby! It blasted off and then flew near the atmosphere at 3,990 kilometers (2,480 mi).

The data collected showed that Venus was hot and filled with clouds. It also taught us more about interplanetary space.

But it wasn’t just the analysis Mariner 5 provided. Every moment zooming by the planet gave us a better look at this fascinating world and its mysterious landscape! This knowledge would go on to shape future missions in their exploration of our solar system.

Mariner 6 and 7

Mariner 6 and 7 were pioneers. Launched a month apart with big dreams, they set out to solve the most mysterious questions about Mars—like, is there water? And maybe even signs of life?

These twin probes had one mission: to study the surface and atmosphere of Mars. Observing closely from their spacecraft, they searched for traces of water and CO2. It didn’t take long before the answer was found — yes! There was evidence that a mix of water vapor and CO2 filled the Martian skies.

The results were groundbreaking, opening up new avenues for such future studies as manned missions. A great feat in space exploration, Mariner 6 and 7 changed everything we knew about Mars at the time — all thanks to their incredible journey.

Mariner 8

NASA’s Mariner 8 was a vessel with a mission for progress. Part of the Mars 71 Project, its intention was to conduct research on the planet’s composition, density, pressure, and temperature. It wanted to measure the atmosphere, as well as surface composition, temperature, and topography.

But it was not meant to be. On launch day, disaster struck; its fuel tank failed, causing it to crash into the Atlantic Ocean. This marked NASA’s third failure in just three attempts.

Still, setbacks can spark something new. Not giving up, scientists continued exploring ways to connect with Mars, leading to more successful ventures in the future. Ingenuity and problem-solving were at play in developing better ideas that offered a lack of risk while maintaining maximum contributions in pioneering knowledge as we march towards space exploration targets.

For Mariner 8, an ocean grave became its resting place, but it taught us invaluable lessons about consistency and resilience—the prerequisites for success in any project or endeavor.

Mariner 9

Mariner 9 had an amazing success story. Though its twin project failed to launch, Mariner 9 went into orbit around Mars and stayed for over a year! It was able to capture 7,329 breathtaking images of the Red Planet, along with two of its moons – Phobos and Deimos. It also sent back a whopping 54 billion bits of data.

This mission was incredibly valuable as it provided key insights that allowed the subsequent Viking Program to make progress. The findings from Mariner 9 broke new ground and set the stage for future interplanetary exploration.

In a nutshell, Mariner 9’s success generated buzz and excitement, encouraging more research on Mars in years to come. Thanks to its daring launch commandeer and superb performance, this spacecraft is remembered as a hallmark of space exploration history.

Mariner 10

Mariner 10 had the first close look at two very different planets in our Solar System. Cutting-edge technology and a risky interplanetary maneuver allowed it to reach both Venus and Mercury.

At Venus, Mariner 10 took in an extraordinary view of its thick, chemically dynamic atmosphere, quickly rotating every four days. Capturing over 4,100 photos amazed scientists with the intricate patterns on the surface.

While making its way to Mercury, Mariner 10 snapped 2,800 photographs of this brutal planet – exposing its strange moon-like appearance that made it clear we weren’t in Kansas anymore!

The impressive mission broke records and illuminated our understanding of space science. It laid a trailblazing path for future newcomers to reach places never before explored by man.
