Exploring Mars: Insights from NASA's Adam Steltzner
Written on
The Mars 2020 Mission Overview
NASA's Perseverance rover is poised to land on Mars soon, and we had the privilege of speaking with Adam Steltzner, the chief engineer behind this ambitious project at NASA's Jet Propulsion Laboratory (JPL). Steltzner, who designed the rover's innovative sample return system, is prominently featured in the upcoming National Geographic documentary, "Built for Mars," which chronicles the challenges of sending this robotic explorer to the red planet. Below is a condensed version of our enlightening discussion.
Section 1.1: Building on Curiosity's Legacy
When planning for Mars 2020, was it always intended to utilize the Curiosity rover's design?
Adam Steltzner: Absolutely! From the outset, our deputy project manager, who previously managed the Curiosity flight system, initiated the idea of leveraging existing resources after Curiosity was launched. He asked, "How much spare equipment do we have?" After Curiosity's launch, there were no plans for follow-up missions, so Matt Wallace explored whether we could utilize leftover components to minimize costs and build a new mission based on the foundation laid by Curiosity.
Section 1.2: Challenges and Opportunities
Were there concepts for Perseverance that you couldn't implement due to constraints?
Adam: Not particularly!
So, you managed to get everything you envisioned?
Adam: Surprisingly, yes! It's uncommon for someone to ask if I got everything I wanted, so it took me a moment to realize that I did.
Section 1.3: Jezero Crater's Geological Importance
What makes Jezero Crater a significant landing site?
Adam: Scientists are particularly interested in Jezero Crater because it was once a lake, and we're landing right at the delta. Deltas are areas where rivers deposit sediments when they flow into larger bodies of water, and these deposits are excellent for preserving signs of ancient life.

Chapter 2: Ingenuity and Sample Return Systems
Nasa's Adam Steltzner breaks down his trajectory to Mars | Roadtrip Nation - YouTube: Adam Steltzner elaborates on the trajectory to Mars and the technology involved, emphasizing the importance of Ingenuity and the sample return mission.
Section 2.1: The Role of Ingenuity
Is there a possibility for the Ingenuity Helicopter to assist Perseverance?
Adam: While Ingenuity serves primarily as a technology demonstration, it could potentially aid surface missions. However, due to its design and limited life expectancy on Mars, we don't plan for its extensive use.
Section 2.2: The Importance of Sample Return
Why is it essential to bring Martian samples back to Earth?
Adam: Bringing samples back allows us to utilize all of Earth's scientific tools and expertise, enabling us to conduct thorough investigations that would be impossible with in-situ measurements alone.
Section 2.3: Ensuring Sample Integrity
How do you prevent Earth contamination in sample collection?
Adam: This is a significant challenge. We've constructed exceptionally clean hardware and developed rigorous cleaning protocols. For instance, we use titanium tubes treated with titanium nitride, which minimizes contamination risk.
Section 2.4: Future of Mars Exploration
How far are we from a potential Mars colonization?
Adam: I hope we are infinitely far from it. Mars is not a hospitable environment for human life, and Earth remains far more suitable for sustaining life.
Section 2.5: The Future of Technology in Space Exploration
What innovations could change planetary exploration?
Adam: Utilizing commercial off-the-shelf technology could revolutionize exploration. For example, integrating consumer electronics into spacecraft systems could enhance performance and reduce costs.
