Unveiling Mars: The Mysterious Phenomena of Twilight Clouds
Ever wondered what the clouds on Mars look like? A recent video captured by NASA’s Curiosity Rover has provided a spectacular display. This footage, recorded on January 17, shows delicate red and fine green clouds drifting across the Martian sky, reminiscent of clouds seen on Earth. Studying these clouds can offer scientists valuable insights into Mars’ climate patterns and the dynamics of its atmosphere.
The images, captured by one of the two cameras aboard the Curiosity Rover, depict what scientists refer to as “noctilucent” or twilight clouds. These clouds are visible high above Mars’ surface, even at night, as they are illuminated by sunlight that penetrates the upper atmosphere. The snapshots were collected over 16 minutes and sped up 480 times to create the video, according to a statement from the Jet Propulsion Laboratory, the institution behind the Curiosity mission.
The twilight clouds on Mars, made of carbon dioxide ice, are also known as dry ice. These clouds form at the highest altitudes, roughly 37 to 50 miles (60 to 80 kilometers) above the surface, where the temperature is lower. This causes the carbon dioxide in Mars’ atmosphere to condense into visible clouds. Some of the ice crystals can be seen falling as thick white streaks before dissipating about 31 miles (50 kilometers) high, where they evaporate due to increasing temperatures.
This marks the fourth year that the Curiosity Rover has witnessed the formation of these clouds, which typically appear in the early autumn season in the southern hemisphere of Mars. According to a statement from the Jet Propulsion Laboratory, these twilight clouds were first observed by a team of scientists back in 1997 during NASA’s Pathfinder mission.
“I will always remember the first time I saw the colorful clouds and I was sure that at first it was a color artifact,” said Mark Lemmon, an atmospheric scientist at the Colorado Space Institute,
Summarizing the curiodity sketches detailing the clouds.
“Now it has become very predictable so that we can plan our shots first; Clouds appear exactly at the same time this year.”
Last September, scientists announced the most extensive map of Mars created, based on two decades of images captured by the European Space Agency’s Mars Express Orbiter. This map catalogs various cloud patterns observed on Mars, including some unique to the red planet, showcasing the diversity of Martian atmospheric phenomena.
“The clouds on Mars are diverse and interesting as we see in our paradise on earth,” Daniela Tirsch, a planetary geologist at the German Aerospace Center, who participated in the catalog,
at the time.
“added that sometimes some clouds have been sighted that are completely different from anything seen in our planet.”
However, the reason why these twilight clouds have only been observed in certain parts of Mars remains a puzzle for Lemmon and other scientists. For instance, since landing in the Jezero Crater in 2021, NASA’s Perseverance Rover has not detected any twilight clouds, despite being located in the northern hemisphere, further north than the Pathfinder’s landing site. Curiosity itself did not detect these clouds until 2019, nearly seven years after landing in the Gale Crater, just south of the Martian equator.
“It is not expected that carbon dioxide will develop on ice here, so there is something that cools it until it can happen,” said Lemmon in the same statement. “Certain areas are likely privileged to form them, because the region where the waves in the atmosphere are known as gravitational waves cool the atmosphere sufficiently to freeze carbon dioxide molecules and sculpt the clouds produced.”
Despite this, he emphasized that Mars’s gravitational waves are not fully understood, and what causes certain places to generate these clouds when others don’t, remains mysterious.
One possible explanation, however, has been suggested by scientists examining the gravitational waves that ripple through Mars’ atmosphere. These waves could cool the atmosphere, allowing carbon dioxide to condense into clouds. Yet, the precise mechanisms and locations of these gravitational waves are still largely unknown, offering ample room for further investigation and research.
Today, understanding these clouds and their formation is more crucial than ever. As NASA continues to prepare for human missions to Mars in the coming decades, detailed knowledge of the planet’s atmospheric dynamics, including nocturnal clouds, can help ensure the safety and success of astronauts. Future missions, like the upcoming Mars Exploration Program, will continue to explore these phenomena, driving our understanding of the Red Planet forward.
Even now, advancements in atmospheric research on Mars are proving invaluable. For example, studies of Martian cloud formations are inspiring new techniques in Earth’s atmospheric science, much like early satellite imagery from Mars transformed our understanding of landscapes and satellite imagery here on Earth, advances that often led to critical environmental insights for our planet. Many U.S. researchers are now collaborating with international partners to share knowledge and technology, enhancing global cooperation in space exploration. Additionally, understanding the dynamics of Martian clouds can provide insights into potential climate change impacts on Earth, reinforcing the importance of continued space research.

Unveiling Mars: The mysterious Phenomena of Twilight Clouds
### Frequently Asked Questions about Martian Twilight Clouds
#### What are twilight clouds on Mars, and how were they discovered?
Twilight clouds on Mars, also known as noctilucent or “dry ice” clouds, are made of carbon dioxide ice and form at high altitudes (37 to 50 miles) where the temperature is significantly lower.These clouds become visible at night due to sunlight reaching through Mars’ upper atmosphere. They were first observed during NASA’s Pathfinder mission in 1997,and NASA’s Curiosity Rover has been documenting them as 2019,with previous observations dating back to the 1990s[3].
#### What do Martian twilight clouds look like?
The Curiosity Rover captured footage showing delicate red and fine green clouds drifting over the Martian sky, reminiscent of Earth’s clouds.This innovative video was created by speeding up 16 minutes of footage, highlighting the beauty and uniqueness of these Martian clouds[2].
#### How are twilight clouds formed on Mars?
Twilight clouds form when carbon dioxide in Mars’ atmosphere condenses into ice at high altitudes,where temperatures are significantly cooler. Some of the ice crystals fall and then evaporate about 31 miles above the surface as temperatures increase. This cycle of formation and dissipation contributes to the clouds’ uniqueness[2].
#### Why are twilight clouds only found in some parts of Mars?
Scientists, including Mark Lemmon, have noted that Twilight clouds are not uniformly distributed across Mars. They typically appear in certain regions, especially during early autumn in the southern hemisphere, which remains an enigma. The phenomenon is linked to atmospheric conditions such as gravitational waves that cool the atmosphere, enabling cloud formation[2].
#### How do these clouds impact Mars research?
understanding Martian twilight clouds is crucial as NASA prepares for human missions to Mars. studying these clouds enhances our knowledge of Martian atmospheric dynamics, which can improve the safety and success of future astronauts. Additionally, insights from Martian clouds can also influence Earth’s atmospheric studies[2].
#### What are scientists doing to study these clouds further?
Future missions, including the Mars Exploration Program, aim to delve deeper into these phenomena, advancing our understanding of the Red Planet. Ongoing international collaboration in space exploration and atmospheric research also plays a significant role in uncovering the mysteries surrounding Martian twilight clouds[1].
### why Should We Care About Martian Clouds?
Studying Martian twilight clouds not only expands our understanding of planetary atmospheres but also sheds light on potential climate change impacts on Earth.
