China’s Zhurong rover rolls onto Martian surface for first time

By

Mars is getting busy, with NASA’s Perseverance and Curiosity rovers and InSight landers being joined by a new explorer: China’s Zhurong rover. Arriving last week and recently sending back its first images from the red planet, Zhurong has now rolled onto the martian surface for the first time.

The rover made it through the grueling entry, descent, and landing phase in which the lander has to pass through the thin Martian atmosphere and slow itself enough to touch down gently on the surface. Still attached to its lander, the rover immediately began collecting telemetry data. With everything looking good, the rover rolled down a ramp off the lander and onto the Martian soil.

According to the China National Space Administration (CNSA), Zhurong touched the planet’s surface at 10:40 a.m. Beijing Time on Saturday, May 22 (10:40 p.m. ET on Friday, May 21).

This makes China the second county to successfully operate a rover on Mars, along with the U.S. Zhurong will now explore the Utopia Planitia region in its three-month mission, searching for indications of water ice and analyzing the chemical composition of the surface.

Zhurong also has a feature no other rover has had before, in terms of its suspension. “It is the first Mars rover with an active suspension system,” China’s state news agency Xinhua writes. “It could help the rover get out of trouble by moving like an inchworm on the complicated Martian surface with both loose sandy soil and densely distributed rocks, said Jia Yang, deputy chief designer of the Tianwen-1 probe, from the China Academy of Space Technology.”

The rover, which is named after a traditional Chinese fire god, weighs 240 kilograms (529 pounds) and is smaller and lighter than NASA’s Perseverance rover. There are some key differences as well: Zhurong is solar-powered, with solar panels on its top which spread out like butterfly wings, while Perseverance is nuclear powered using a radioisotope power system. As the sunlight on Mars is weaker than on Earth, Zhurong can turn its solar panels to face the sun as it moves to maximize the amount of energy it can collect.

Crew Dragon is about to fly with empty seats for the first time. Here’s why
A Falcon 9 rocket launches from California.

NASA and SpaceX are making final preparations for the Crew-9 astronaut flight to the International Space Station (ISS), which is set to launch from the Kennedy Space Center in Florida on Thursday, September 26.

But this will be the first of SpaceX’s 13 crewed flights to the ISS since the first one in 2020 where there will be two empty seats on the Crew Dragon spacecraft. And there’s a very good reason for that. Let us explain.

Perseverance rover gears up for a big climb to the rim of the Jezero Crater
One of the navigation cameras aboard NASA’s Perseverance Mars rover captured this view looking back at the “Bright Angel” area on July 30, the 1,224th Martian day, or sol, of the mission.

The Perseverance rover on Mars is set to begin its newest challenge: a slog up the rim of the Jezero Crater that will take months to complete. The rover will face steep slopes and difficult terrain, testing its wheels and suspension system, but its efforts should help to uncover rocks from the most ancient part of the Mars crust.

Since the rover landed in the Jezero Crater in 2021, it has been exploring the floor of the crater and the site of an ancient river delta. This area was chosen because it was once home to an ancient lake, so the rock cores that the rover has collected will help to uncover information about the history of water on Mars -- which is vital to determine if the planet could ever have been habitable.

Perseverance rover finds tantalizing hints of possible ancient life on Mars
mars 2020 perseverance rover

NASA's Perseverance rover was sent to Mars with one big, ambitious aim: to see if life could ever have thrived on our neighboring planet. Although there's unlikely to be anything alive on Mars now, the planet was once similar to Earth, with a thicker atmosphere and plentiful water on its surface. And during this time, billions of years ago, microbial life could have survived there. Now, Perseverance has located some tantalizing indications of possible microbial life -- although it's too early for scientists to be sure.

The rover has been taking samples by drilling into the martian rock as it travels, and it's a recent sample from an area called the Cheyava Falls that has ignited interest. The rock, collected on July 21, has indications of chemical signatures and physical structures that could potentially have been formed by life, such as the presence of organic compounds. These carbon-based molecules are the building blocks of life; however, they can also be formed by other processes.
