On May 14th, 2021, the China National Space Agency (CNSA) achieved another major milestone when the Tianwen-1 lander successfully soft-landed on Mars, making China the second nation in the world to land a mission on Mars and establish communications from the surface. Shortly thereafter, China National Space Agency (CNSA) shared the first images taken by the Tianwen-1 lander.
By May 22nd, 2021, the Zhurong rover descended from its lander and drove on the Martian surface for the first time. Since then, the rover has spent 63 Earth days conducting science operations on the surface of Mars and has traveled over 450 meters (1475 feet). On Friday, July 9th, and again on July 15th, the CNSA released new images of the Red Planet that were taken by the rover as it made its way across the surface.

One of the hardest things to reconcile in science is when new data either complicates or refutes previously findings. It’s even more difficult when those findings were widely publicized and heralded around the community. But that is how science works – the theories must fit the data. So when a team from JPL analyzed data from Mars Express about the Martian South Pole, they realized the findings announced in 2018 about subsurface lakes on Mars might have been more fraught than they had originally thought.

Ever since 1971, when the Mariner 9 probe surveyed the surface of Mars, scientists have theorized that there might be subsurface ice beneath the southern polar ice cap on Mars. In 2004, the ESA’s Mars Express orbiter further confirmed this theory when its Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument detected what looked like water ice at a depth of 3.7 km (2.3 mi) beneath the surface.
These findings were very encouraging since they indicated that there could still be sources of liquid water on Mars where life could survive. Unfortunately, after reviewing the MARSIS data, a team of researchers led from Arizona State University (ASU) has proposed an alternative explanation. As they indicated in a recent study, the radar reflections could be the result of clays, metal-bearing minerals, or saline ice beneath the surface.

Remember the stunning video of the Perseverance rover landing on Mars? The Chinese National Space Administration (CNSA) has now released similar video footage from its Zhurong rover, including the sounds recorded as it plummeted through the Martian atmosphere on its way to landing in Utopia Planitia. The CNSA also released sounds of the rover driving off the landing platform.

New images from orbit and from Mars’ surface show the Zhurong rover on the move. China’s National Space Administration (CNSA) released new pictures and video this week, and NASA’s Mars Reconnaissance Orbiter has followed the rover’s movements from above.
The image above shows wheel tracks left behind by the Zhurong rover.

There will be all sorts of risks for any future colonists on Mars, such as extreme weather and temperatures, radiation, and the human physiological problems associated with living in with decreased gravity. But another issue means colonists on Mars will have to be on a constant lookout above their heads.

Laying on a grassy field staring at the cloud formations in the sky and coming up with harebrained ideas about their shapes is a common feature in childhood summers – at least as they’re portrayed in media. Someday that image might translate to a child laying on a sandy or rocky outcropping, looking up at the sky seeing iridescent, shimmering clouds in the sky. The biggest differences would be that the child would be looking through a visor, and those clouds would be on Mars. And Curiosity recently released some stunning images of what they might look like.

Ever have an idea that was so crazy that it just might work? A few weeks ago, members of the InSight Mars team came up with a crazy, counter-intuitive way to try to get dust off the lander’s solar panels: pour *more* dust on the panels.
Yes, that sounds crazy. But yes, it actually worked!

When NASA’s Perseverance rover landed in the Jezero crater on February 18th, 2021, it brought with it an interesting little companion that’s been causing quite a stir of late! We are talking, of course, about the Ingenuity Mars Helicopter, an experimental flight system designed to demonstrate if aerial systems can work on Mars. Since its inaugural flight on April 19th, the helicopter has been pushing the boundaries of flight on Mars, going farther and faster each time.
In fact, the helicopter managed to establish multiple records in the course of its first five flights, reaching a maximum distance of 266 m (873 ft) in 117 seconds. Unfortunately, things did not go so well for Ingenuity during its sixth and latest flight. Due to a navigation timing error, the helicopter strayed from its flight path, but managed to land safely just a few meters from where it was supposed to.

NASA’s Ingenuity helicopter is a stunning achievement of engineering, design, and, well, ingenuity. The dual-rotor craft can be seen taking off and landing in this remarkable video, taken by the Mastcam-Z, an imager aboard the Perseverance Mars Rover. Mastcam-Z is a tremendous scientific instrument, but this article’s truly outstanding lead image was taken with Perseverance’s SuperCam instrument.
