On July 4th, 1997, NASA’s Mars Pathfinder mission touched down on Mars, ending a 15 years period where no spacecraft operated in the Red Planet. Twenty years later, the mission’s impact on our understand of Mars is still felt. Jake is joined by Matt Golombek (Project Scientist), Brian Muirhead (Flight Systems Manager & Deputy Project Manager), Donna Shirley (Mars Exploration Program Manager), and Tanya Harrison (Planetary Scientist) who recount the story and explain why the mission plays suc...

Europe’s ExoMars program has already kicked off with the Trace Gas Orbiter, currently manoeuvring downward to its final science orbit. But ExoMars is not limited to a single mission. By 2020, ESA hopes to launch the first European rover to the Red Planet. Abbie Hutty, a Lead Spacecraft Structures Engineer, comes on to talk about what it takes to design, test and build a rover chassis, from wheels to mast, and what this rover means in the broader view of Mars exploration and international coopera...

All the obstacles in spaceflight can theoretically be broken down in to subsets of risk. Whether personal risk, programmatic risk, financial risk or professional risk, these are the things holding back individuals and organizations from accomplishing goals. What does this mean for Mars and how can we overcome it? Jake sits down with award-winning journalist Leonard David to explore this topic and try to understand what steps must be taken next to continue towards the objective of putting people ...

On Earth, geologists are pretty familiar with the concept of an esker, a snake-like ridge formation left behind by a receding glacier. Across our planet they can be found in areas where glaciers once dominated the landscape. The same is true on Mars, but eskers also require a time when glaciers could melt . Frances Butcher, a PhD student from the Open University, talks with Jake about these special kinds of Martian eskers that indicate a warmer, wetter environment than we once thought. Links Mar...

Ahead of the science, the surface operations, the tricky landing, interplanetary cruise, & launch of a NASA flagship class rover like Mars2020, the difficult decision of where to send the mission must be made. For the successor of Curiosity, this process is nearing completion as the 3rd workshop has narrowed the remaining candidates to three. Jake takes a long look at the mission requirements, landing site criteria, and Mars mapping techniques before exploring Jezero Crater, North East Syrti...

A surface mission to Mars will involve a lengthy stay in a harsh environment. Many have argued that this could be a psychologically draining experience as astronauts are forced into confined spaces with no light, perhaps underground away from harsh radiation. But architects Kelsey Lents and Jeffrey Montes don’t believe that’s necessary. They and their teams helped design the Mars Ice House, a 3D-printed ice dome that caught the eye of NASA and became a feasibility study to build a surface habita...

The year 2016 was a big one for Mars, and 2017 might be even bigger yet. We’re joined by two space reporters from Orlando to talk about the highlights of last year in Mars exploration, and look ahead to 2017, which promises to take us closer to the Red Planet.

NASA currently operates two rovers on the surface of Mars, but in the next five years that population could more than double as JPL prepares its third rover, and space agencies in Europe and China look to create their own footholds. That’s why creating a pipeline of talent that can plan, target, drive and otherwise operate these rovers is so important. Enter CanMars – an anlogue mission run by the Canadian Space Agency using real rovers here on Earth. I caught up with Eric Pilles, the planning l...

Living and working in a remote place requires more than just food, water, shelter and air. If we’re serious about maintaining the health of our future Martian astronauts, we’ll need to pay close attention to the mental health, and we’ll need to figure out a way to make food sustainable. The idea of farming on Mars isn’t new, but the ideas of Morgan Irons, founder and Chief Science Officer of Deep Space Ecology, certainly push them forward. Her “three-zone model” promises to create a closed ecolo...

Some call water the “oil of the solar system” because of its importance in our eventual exploration of other planets. Finding new sources and learning about how to access it plays a key role in our future. Using the SHARAD instrument on the Mars Reconnaissance Orbiter, Cassie Stuurman and a team at University of Texas at Austin discovered a massive deposit of ice in the northern plains of Utopia Planitia. Cassie joins us to tell the tale of its discovery, characterization and importance. Links C...

The ExoMars Trace Gas Orbiter’s primary mission is to hunt down sources of trace gasses in the orbiter and characterize them. Chief among these chemicals is Methane, and when it is isolated on the surface, we’re going to want to know what that place looks like. Enter the Colour and Stereo Surface Imagine System, a state of the art instrument that can take stereo images of the surface, allowing us to see Mars in 3D.

Elon Musk has now bore his heart (of gold) to the world. His plans for making humans multiplanetary have been shared with us, including his incredible 42-engine reusable booster, his 100-person interplanetary spaceship, and his vision for colonizing Mars. Together they form the SpaceX Interplanetary Transport System, and they are nothing if not bold. I’m joined by Anthony Colangelo from the Main Engine Cut Off Podcast to talk more about this vision, including some of the realities of making it p...

Understanding human social behaviour under conditions of remote isolation, close quarters, and constrained resources will one day be critical to successfully executing a crewed mission to Mars. Analogues and simulations provide a useful tool to learn these tactics. HI-SEAS IV (Hawaii Space Exploration Analogue and Simulation) is one such experiment, and six crewmembers recently exited after an entire year in a dome on the slopes of a Hawaiian volcano. We spoke with all six members of the crew an...

The Mars Curiosity Rover has an impressive suite of instruments, but none incite as much excitement as ChemCam, a laser/camera combo that vaporizes rocks and analyzes their components. ChemCam is firing more than it ever has before, and Nina Lanza, a staff scientist on its team, is helping make some pretty remarkable discoveries with it. On this episode, Nina tells us about a high concentration of manganese recently uncovered that tells us a lot about Mars’ past, and suggests that it might have ...

Electric vehicles aren’t just taking over our roads – they’re taking over our orbits, too! Solar electric propulsion is a cutting edge technology that allows spacecraft to change velocity up to an order of magnitude more efficiently than traditional chemical rockets.

Increasingly, Mars is appearing to us as a living, breathing world with dynamic features. One such feature that has captivated planetary scientists around the world is the occurrence of Martian Gullies, channels carved into the surface as if by water, in a world where flowing water is not exactly common.
