China’s Rover Found Evidence of an Ancient Ocean on Mars

In a recent study published in National Science Review, a team of researchers led by the China University of Geosciences discuss direct evidence of an ancient ocean and its shoreline that existed in the northern hemisphere of Mars during the Hesperian Period, or more than 3 billion years ago. This finding is based on data collected by the China National Space Agency’s (CNSA) Zhurong rover in the Vastitas Borealis Formation (VBF), which lies within southern Utopia Planitia on Mars.

China's Mars Rover Finds Recent Evidence of Water Near the Equator

The surface of Mars is a pretty desolate place at first glance. The soil is many times as dry as the driest desert on planet Earth, the temperatures swing from one extreme to the other, and the air is incredibly thin and toxic. And yet, there’s ample evidence that the planet was once much warmer and wetter, with lots of flowing and standing water on its surface. Over time, as Mars’ atmosphere was slowly stripped away, much of this water was lost to space, and what remains is largely concentrated around the poles as glacial ice and permafrost.

For years, space agencies have been sending robotic landers, rovers, orbiters, and aerial vehicles to Mars to learn more about when this transition took and how long it took. According to China’s Tianwen-1 mission, which includes the Zhurong rover, there may have been liquid water on the Martian surface later than previously thought. According to new research from the Chinese Academy of Sciences (CAS), the Zhurong rover observed salt-rich dunes in the Utopia Planitia region that showed cracks and crusts, indicating the possible presence of water as recently as a few hundred thousand years ago.

The Zhurong Rover has sat unmoving and unresponsive on Mars since May 20^th, 2022, when one of the planet’s infamous dust storms forced the science team to switch the rover to hibernation mode. It was expected to wake in late December, but has yet to show any signs of activity. Last week, the Rover’s chief designer, Zhang Rongqiao, offered an update on the rover’s status.

New Pics of Phobos From China’s Tianwen-1 Orbiter

Two fundamental factors affect all astrophotography – timing and location. If a camera happens to be at the right place at the right time, it can capture images that have never been seen before. And with the proliferation of cameras throughout the solar system, more and more novel photos will be captured at an ever-increasing frequency. China’s Tianwen-1 probe added to that novel collection to celebrate its second anniversary by taking a shot of Mars’ moon Phobos.

China’s Tianwen-1 has Imaged the Entire Surface of Mars, Completing its Primary Mission

After exploring Mars for more than a year, China’s Tianwen-1 space probe has successfully taken images covering the entire Red Planet, China’s National Space Administration (CNSA) announced on June 29. Tianwen-1, which translates to “quest for heavenly truth”, consists of six separate spacecraft: an orbiter, two deployable cameras, lander, remote camera, and Zhurong rover. The images in question were taken by the orbiter while circling Mars 1,344 times, capturing images of the Red Planet from every angle while Zhurong explored the surface. in the statement, CNSA said the probe has now completed all of its tasks, which included taking medium-resolution images covering the entire planet.

Two Lego designers with a history of space-themed projects have teamed up for a new proposed set: China’s Long March CZ-5 and Tianwen-1 Mission. The set is currently gathering supporters on the LEGO Ideas website. If it gets enough support, LEGO will review it and possibly create it.

Remember how China’s Tianwen-1 spacecraft released a remote camera to take a picture of itself during its flight to Mars, back in late 2020? Now in Mars orbit, Tianwen-1 has done it again, releasing another mini remote camera. Except this time, the planet Mars is part of the view.

The images are stunning.

New Images of Mars From China’s Rover

On May 14^th, 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 22^nd, 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.

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.
