Understanding Mars’ clouds helps us learn about the planet’s weather, including dust storms. This knowledge is crucial for future missions, especially those involving landing on Mars.
Volcanic Features
Mars has some incredible features, like Arsia Mons, a massive volcano. Standing at 12 miles high, it’s about twice the height of Earth’s biggest volcano, Mauna Loa. The southernmost volcano in the Tharsis region, Arsia Mons is known to have thick clouds. These clouds appear when air rises up the volcano, cools, and condenses. They are most noticeable when Mars is farthest from the Sun, during a time called aphelion. This results in what scientists call the "aphelion cloud belt," beautifully shown in recent images.
Jonathon Hill from Arizona State University shared his excitement: “We hoped to see the summit peak through the morning clouds, and it didn’t disappoint.”
The THEMIS Camera
The Thermal Emission Imaging System (THEMIS) camera on Odyssey captures images in visible and infrared light. This capability lets scientists identify water ice below the surface, which could support future astronauts. Additionally, THEMIS can image Mars’ two small moons, Phobos and Deimos, providing insights into their composition.
NASA’s Odyssey Project
NASA’s Jet Propulsion Laboratory (JPL) manages the Mars Odyssey Project, part of the larger Mars Exploration Program. The spacecraft was built by Lockheed Martin Space and works closely with JPL for mission operations. The THEMIS camera is created and operated by Arizona State University.
As we explore Mars, understanding its clouds, volcanoes, and the tools we use is essential. This research not only enriches our knowledge of the planet but also prepares us for human exploration.
