As NASA's Perseverance rover explores Mars since its February landing, China's Tianwen-1 mission prepares its Zhurong rover—named after an ancient fire god—for a mid-May touchdown on the Red Planet.
China's ambitious Tianwen-1, the nation's first interplanetary mission, targets Utopia Planitia—a vast rocky plain where NASA's Viking 2 landed in 1976. The landing sequence draws from proven techniques: parachute deployment, retro-rocket firing, and inflatable airbags reminiscent of the 1997 Pathfinder mission. Success would make China only the second country after the U.S. to achieve a soft Mars landing.
On April 24, the China National Space Administration (CNSA) announced "Zhurong" as the rover's name, chosen from public submissions by experts and agency officials. Measuring 1.85 meters long and weighing 240 kg, Zhurong is compact—smaller than Perseverance but larger than NASA's original Spirit and Opportunity rovers.
Designed for a 90-Sol (92.5 Earth-day) lifespan, Zhurong reaches speeds of 200 meters per hour. Like its lunar counterpart Yutu-2, which exceeded 800 days on the Moon's far side, it may outlast expectations. Solar-powered and comparable to a 500-pound golf cart, it will probe Martian subsurface water and map geological features.
Meanwhile, NASA's Ingenuity helicopter has completed three successful flights. Flight one: 3+ meters altitude for 39 seconds. Flight two: 4 meters up for 52 seconds, shifting 4 meters laterally. Flight three: 5.2 meters high, traveling 50 meters at over 2 m/s.
These tests pave the way for Perseverance's core mission: seeking ancient life signs in Jezero Crater, collecting returnable samples, and already producing oxygen on Mars.
