Mars-Sample-Return Derailed: U.S. Bill Pins Hopes on China’s Mars Life Hunt

A U.S. spending bill effectively cancels NASA’s Mars Sample Return program, ending plans to bring Perseverance’s Martian rocks to Earth due to cost and schedule concerns (independently estimated around $11 billion). NASA will still fund related Mars-tech under the Mars Future Missions umbrella, but the race to return samples may now favor China, whose Tianwen-3 mission aims to collect rocks in 2028 and return them by 2031, potentially giving Beijing the lead in finding signs of life on Mars.

"Race to Mars: China's Sample Return Mission vs. U.S. Science Prize Stakes"

China aims to launch its Tianwen-3 Mars sample return mission around 2030, with potential landing areas narrowed down to Chryse Planitia, Utopia Planitia, and Amazonis Planitia. The mission will involve a lander and ascent vehicle, an orbiter and return module, and aims to deliver around 500 grams of Martian samples to Earth. The mission faces challenges in obtaining rock samples, taking off from Mars, and transferring samples to a reentry module. The chosen landing site will prioritize astrobiological relevance and geological diversity, with the potential to provide groundbreaking insights into Mars' geological processes and history, and possibly even biosignatures or traces of past or extant life.

"Chinese Scientists Simulate Mars Atmosphere for Sample-Return Missions"

Chinese scientists have developed a numerical model called GoMars to simulate the Martian atmosphere, aiding China's plans for a Mars sample-return mission. The model will help simulate meteorological conditions for spacecraft landing, including temperature, wind, and dust. China plans to launch the Tianwen-3 mission between 2028 and 2030, which will collect Martian rock samples using a drill and robotic arm. The atmospheric model will assist in designing materials suitable for Mars rovers to withstand extreme cold temperatures.

China's Ambitious Mars Sample Return Mission Set to Outpace NASA

China is planning to send crewed missions to Mars and return samples of Martian soil and rock to Earth ahead of NASA's proposed Mars Sample Return mission. Chinese scientists have developed a new numerical model called GoPlanet-Mars to simulate the atmospheric environment of Mars, providing crucial information for landing, sampling, and returning tasks. The model successfully reproduced the unique characteristics of Mars' surface pressure and provided good simulation performance for temperature, wind, polar ice, and dust. This model will aid in mission planning and design, as well as analyzing the causes of dormancy and developing materials suitable for Mars rovers.
