THey Viking 1 lander arrived on the Martian surface 46 years ago to investigate the planet. It dropped down into what was thought to be an ancient outflow channel. Now, a team of researchers believes they’ve found evidence of an ancient megatsunami that swept across the planet billions of years ago, less than 600 miles … Read more
The average temperature on Mars is minus 80 degrees Fahrenheit. Mars, the Red Planet of our solar system, is popular for its rusty iron structure present on the ground. According to American space agency NASA, the average temperature on Mars is minus 80 degrees Fahrenheit – way below the freezing temperature. In conclusion, no water … Read more

On August 30, a solar storm (a coronal mass ejection, or CME) struck Mars, leading to the discovery of simultaneous double auroras by NASA’s MAVEN spacecraft. This artist’s concept of the CME striking the dayside of Mars, driving a proton aurora (a type of Martian aurora that forms as the CME interacts with Mars’ upper … Read more
Two cameras on the Mars Express orbiter captured images of a series of dust storms near the Martian North Pole in 2019. Analysis of the images indicates that big clouds of dust on Mars formed similarly to water vapor clouds on Earth—an unintuitive finding, given how different the planets are. Most clouds on Earth are … Read more
Kneeling on the edge of a deep crater, astronaut Alexander Gerst uses a chisel to collect a sample of volcanic rock which he carefully puts inside a white plastic bag. Gerst is not on the Moon, even if he looks like it. He is in the middle of Los Volcanes Natural Park on the island … Read more
The second model sought to identify the physical and chemical characteristics of Mars’s porous crust – namely, temperature, chemical composition, and the presence of liquid water. These were partly determined by surface conditions (ie, surface temperature and atmospheric composition) and partly by the planet’s internal characteristics (ie, internal thermal gradient and crust porosity). These first … Read more
Illustration of Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID). NASA/ULA Space agency NASA has tested a new way of landing on Mars that could make future missions to the red planet and beyond both possible and affordable. The 20-feet diameter inflatable heat shield, which could one day help land astronauts on Mars, autonomously … Read more
An artist’s impression of the Mars Express spacecraft.Drawing: ESA For 19 years, the Mars Express spacecraft has orbited the Red Planet, providing breathtaking views and valuable insights of Mars. The hard-working orbiter has not only relayed its own data back to Earth, but also provided a communication line between other Martian missions and ground control. … Read more
