In a quirky, fun campaign, NASA has released retro-looking posters to attract brave, adventurous and talented people to help set up a colony on Mars.

The eight posters by the US space agency show a range of key occupations that will be required to test human survival on the neighbouring red planet.

The posters, called “Mars Explorers Wanted”, have been designed to excite the public about the possibilities of living on another planet, and the role they could play in it as farmers, teachers, surveyors and technicians.

The set of images were first created in 2009 for an exhibit at the Kennedy Space Center in Cape Canaveral, Florida, to offer a glimpse of how exciting it would be to explore the red planet, and serve as a reminder that robots and probes can only go so far in exploring other celestial bodies.

Here's a look at the posters.

Night owls welcome! 

"If you lived on Mars' moon Phobos, you'd have an office with a view, mining for resources with Mars in the night sky. Settlers below on Mars would see Phobos rise and set not once, but twice in one day!"

Got a green thumb? 

"This one's for you! In space, you can grow tomatoes, lettuce, peas, and radishes just like you would find in your summer garden. New ways of growing fresh food will be needed to keep brave explorers alive."

 Surveyors wanted!

"Have you ever asked the question, what is out there? So have we! That curiosity leads us to explore new places like Mars and its moons, Phobos and Deimos. Just what lies beyond the next valley, canyon, crater, or hill is something we want to discover with rovers and with humans one day too."

Learning is out of this world! 

"Learning can take you places you've never dreamed of, including Mars and its two moons, Phobos and Deimos. No matter where we live, we can always learn something new, especially with teacher-heroes who guide us on our path, daring us to dream and grow!"

 Engineer our future on Mars

"People with special talents will always be in demand for our Journey To Mars. Whether repairing an antenna in the extreme environment of Mars, or setting up an outpost on the moon Phobos, having the skills and desire to dare mighty things is all you need."

Build our future on Mars

"Are you someone who can put things together, solving challenges to ensure survival? Dare to forge our future with space-age tools - build spaceships to carry us to Mars and back, and habitats to protect us while we're there."

We Need You

"We need many things for our Journey To Mars, but one key piece is YOU!"

NASA had released another set of retro posters earlier this year called the “Visions of the Future” which promoted travel to other destinations in the solar system.

One of the posters, called ‘The Grand Tour’ honours NASA’s Voyager mission, which sent back breathtaking images while exploring Jupiter, Saturn, Uranus and Neptune using the gravity of each planet.
