Discover Mars: A Stunning Flight Over Water-Weathered Landscapes with Mars Express
Explore the power of water on Mars with ESA’s Mars Express. This flight showcases the Oxia Palus region, covering about 890,000 km², more than twice the size of Germany. The tour features Ares Vallis, one of Mars’s largest outflow channels, which stretches over 1700 km from the southern highlands to Chryse Planitia’s plains.
Billions of years ago, water flowed through Ares Vallis and other channels, shaping the landscape we observe today.
Our flight begins at the landing site of NASA’s Pathfinder mission. The Sojourner rover explored Ares Vallis for 12 weeks in 1997. As we proceed south, we pass over the Masursky and Sagan craters. The Masursky Crater shows signs of past water flow from Tiu Vallis.
The Masursky Crater contains jumbled blocks, leading us to Hydaspis Chaos, known for its chaotic terrain. This area appears mixed due to sudden water release from underground, causing the surface to collapse into blocks.
Next, we see the Galilaei crater, which likely once held a lake that overflowed. We also observe streamlined islands and terraced riverbanks, indicating past water flow direction.
How will the insights from Dr. Helena Fischer contribute to the success of the ExoMars Rosalind Franklin rover mission?
Exploring Mars: An Interview with Dr. Helena Fischer, ESA Mars Express Specialist

Interviewer: Thank you for joining us today, Dr. Fischer. We’re excited to discuss the recent insights provided by ESA’s Mars Express regarding the Oxia Palus region and its remarkable features. Can you begin by explaining the significance of Ares Vallis?
Dr. Fischer: Ares Vallis is a critically important geological feature on Mars. It is one of the largest outflow channels on the planet, stretching over 1,700 kilometers from the southern highlands to the plains of Chryse Planitia. This ancient river-like structure provides compelling evidence of past water flow, which is crucial for understanding Mars’s hydrological history.
Interviewer: The film showcasing the Oxia Palus region sounds fascinating. What insights does it offer regarding past water activity on Mars?
Dr. Fischer: The film captures how billions of years ago, water coursed through Ares Vallis and shaped the Martian landscape. The imagery reveals various landforms, such as the Masursky Crater, which shows signs of water flow from Tiu Vallis and includes jumbled blocks indicative of water’s transformative impact. For instance, the chaotic terrain seen in Hydaspis Chaos is a visual reminder of sudden water releases, which caused significant surface collapses.
Interviewer: It’s incredible to see these landscapes rendered in 3D. Can you explain how these visuals were created and the technology behind it?
Dr. Fischer: Certainly! The stunning visuals were produced using data from the Mars Express High Resolution Stereo Camera. We combine single-orbit observations with topographical data, creating a 3D perspective. This involves a rigorous processing of camera data, conducted by the German Aerospace Center and with support from the Freie Universität Berlin’s Planetary Science group. Each second of the film consists of 50 frames, enriched with vertical exaggeration and atmospheric effects to enhance realism.
Interviewer: The Oxia Planum area is mentioned as the planned landing site for the ExoMars Rosalind Franklin rover. Why is this region particularly suited for the mission?
Dr. Fischer: The Oxia Planum region is ideal for the ExoMars mission because it showcases extensive evidence of past water activity. This area’s geological features, shaped by ancient floods, may harbor signs of past life. Studying these features can give us critical insights into the conditions that might have supported life on Mars, making it a compelling target for exploration.
Interviewer: what are your hopes for future explorations on Mars, specifically with regards to the findings from the Mars Express?
Dr. Fischer: My hope is that the Mars Express continues to illuminate the planet’s past, particularly its water history, which is directly linked to the possibility of life. The data and visuals obtained will guide future missions, including ExoMars, and hopefully lead to groundbreaking discoveries regarding the presence of life or the conditions that might have sustained it in the past.
Interviewer: Thank you, Dr. Fischer, for sharing these exciting insights about Mars and the ongoing exploration efforts!
Dr. Fischer: Thank you for having me! The exploration of Mars is an exhilarating journey, and I look forward to what lies ahead.
Continuing past Ares Vallis, we arrive at Oxia Planum, the planned landing site for ESA’s ExoMars Rosalind Franklin rover. This mission aims to find signs of life on Mars, making this water-flooded region an ideal choice.
The flight concludes with a breathtaking overview of Ares Vallis and its water-rich surroundings.
