China's Tianwen-1 probe has sent back its first image of Mars, the national space agency said, as the mission prepares to touch down on the Red Planet later this year.

The spacecraft, launched in July around the same time as a rival US mission, is expected to enter Mars orbit around February 10.

The black-and-white photo released late Friday by the China National Space Administration showed geological features including the Schiaparelli crater and the Valles Marineris, a vast stretch of canyons on the Martian surface.

The photo was taken about 2.2 million kilometres (1.4 million miles) from Mars, according to CNSA, which said the spacecraft was now 1.1 million kilometres from the planet.

In 1972, the space race officially ended as NASA sent one last crew of astronauts to the surface of the moon (Apollo 17). This was the brass ring that both the US and the Soviets were reaching for, the "moonshot" that would determine who had supremacy in space. In the current age of renewed space exploration, the next great leap will clearly involve sending astronauts to Mars.

This will present many challenges that will need to be addressed in advance, many of which have to do with simply getting the astronauts there in one piece! These challenges were the subject of a presentation made by two Indian researchers at the SciTech Forum 2020, an annual event hosted by the International Academy of Astronautics (IAA), RUDN University, and the American Astronomical Society (AAS).
